WATCHDOG MONITOR Circuit

Even when all precautions are taken so that voltage surges do not cause damage to the control panel, it is possible to cause temporary disruption to the operation of the microprocessor causing it to lose track of the program sequence. The PC2550 is equipped with an external Watchdog Monitor circuit which continually checks the microprocessor program execution.
System Supervision Features
The PC2550 continuously monitors a number of possible trouble conditions including: An active battery supervision circuit that periodically tests the battery under load. A loss of the AC power supply. A supervised circuit trouble condition. A telephone line monitoring circuit. A bell circuit failure indicates open circuit or fuse failure. A test code feature which transmits a communicator test code to the monitoring station at a selected time everyday. The test code can be sent at intervals from 1 to 99 days. A bell/siren/communicator test feature which can be activated from the keypad. TLM (Telephone Line Monitoring) restoral transmission.

INSTALLATION

Bench Testing
The PC2550 contains a factory default program. Any additional programming required can be done through the keypad. For many applications all that will be required is to enter the telephone number and alarm codes with keypad entries that are as straight forward as dialing a telephone number. If you need help talk to your DSC equipment distributor. Connect 1K ohm 1/2 watt end of line resistors from each zone (Z1 to Z8) input to the closest common COM terminal. Connect an end of line resistor between the Fire input terminal and the COM terminal between Z1 and Z2. Unless all zone loops are properly terminated with end of line resistors the Ready light will not be on and the panel will not arm unless the Ready light is on. Connect the four keypad wires to the control panel as shown in the connection drawing. To completely test the PC2550 including the communicator data, it is necessary to connect the panel to a digital receiver through a telephone line connection or by connecting the telephone terminals on the PC2550 to a digital communicator test set such as the DSC DTS1. The DSC DTS-1 digital communicator test set is an inexpensive unit which can simulate the telephone system dial tone and the receiver hand shake and kissoff tones as well as display the data sent out by a digital communicator. Also, the DTS-1 has a listen-in feature which makes it ideal for monitoring the transmission between communicator and receiver when the PC2550 is connected to the telephone line. If you are using a DTS-1, connect the green and red telephone clips to the TIP and RING terminals and connect the red and black power clips to the AUX [+] and AUX [-] terminals on the PC2550. When power is applied to the panel press the red local-line button on the DTS-1 and observe the display window area. The local-line indicator should be in the local position. For testing purposes, so that the sound level is not too loud, connect a small buzzer to the BELL [+] and BELL [-] terminals to indicate when the panel is in alarm. Connect a 16.5 VAC, 40 VA transformer to the AC terminals. Before plugging in the transformer be sure the circuit board is not resting on anything metallic which may cause a short. Note: THE PC2550 WILL NOT START UP IF AC IS OFF AND THE BATTERY IS LOW. When the transformer is plugged in there should be lights on the keypad and the buzzer connected to the bell terminals may go on for a few seconds. The Armed light may be on or off the first time the panel is powered. The last armed/disarmed condition is stored in the EEPROM memory so the panel will always power up in the last armed/disarmed state. If the Armed light is on, enter the default Master Code [1234] to disarm the panel. If the keypad is not active, check for the presence of AC power at the AC terminals, check the keypad connections and check the panel fuses. If all the zones are properly connected with end of line resistors all of the zone lights will be off. Note that the panel will arm only if all zones are properly connected with end of line resistors (including FIRE circuit) so that the Ready light is on. The keypad should beep several times to indicate acceptance of the master code. Enter the Master Code to arm or disarm the panel. Read the Keypad Commands section of this manual or the Instruction Manual and enter commands on the keypad to become familiar with the different commands. Turn to the Programming Guide in this manual and enter a sample program into the panel through the keypad to become familiar with the programming commands.

Note: Ensure that plugs and jacks meet the dimension, tolerance and metallic plating requirements of 47 C.F.R. Part 68, Subpart F. For proper operation there must be no other telephone equipment connected between the control panel and the telephone company's facilities. Do not connect the alarm panel communicator to telephone lines intended for use with facsimile (FAX) machines. These lines may incorporate a voice filter which disconnects the line if other than FAX signals are detected, resulting in incomplete transmissions. Battery Connections Do not connect the battery or the transformer until the wiring is complete. Connect the red battery lead to the positive battery terminal and the black lead to the negative battery terminal. If the connection is made in the reverse the battery fuse will fail. The battery charging voltage is factory adjusted for 13.8 volts and normally needs no adjustment. If the battery charging voltage is out of adjustment contact your service representative. Note: The battery charging voltage must not be adjusted on UL listed systems. Keypad Installation Mount the keypads near the exit-entry doors. The PC2550RK keypad has a red, a black, a green and a yellow wire on the back. Connect these four wires to the four keypad terminals on the control panel using four conductor (quad) telephone wire. Up to three keypads may be connected to one PC2550. Connect all green wires from the keypads to the GRN terminal on the
panel. Connect all yellow wires from the keypads to the YEL terminal on the panel. Connect all red wires from the keypads to the RED terminal. Connect all black wires from the keypads to the BLK terminal. Power-up Procedure If the keypads are located a distance from the panel, install an extra keypad temporarily at the panel during power up testing. An extra keypad with a short length of cable and alligator clips attached is helpful for testing and programming PC2550 systems. Connect the transformer, wait approx. 5 seconds. Enter a few keypad commands and open a zone to be sure that the panel and keypad are responding to signals. If the keypad does not respond and there are no indicators on, check for AC voltage at the AC terminals. If there is 16 VAC present, check that the keypad wiring is correct and check the keypad/auxiliary supply fuse. If the keypad/auxiliary supply fuse is blown check for a short between the keypad red and black wires before replacing the fuse. If the keypad is responding normally, connect the battery. The red battery lead attaches to the positive battery post and the black battery lead attaches to the negative battery post. Note : THE PC2550 WILL NOT START UP IF AC IS OFF AND THE BATTERY IS LOW. Testing The System See Installers test - [D] [6] [Master Code] [0] (page 9), or do the following. Contact the monitoring station to request a transmission test. Plug the telephone cord into the RJ31-X jack. If a DTS-1 is being used to monitor communicator transmissions, connect as described in Bench Testing section and place the DTS-1 in the line mode by pressing the red LINE/LOCAL button. Arm the panel, wait for the exit delay to expire and trip a detector on an instant circuit. Wait for the communication to complete. Disarm panel and check with the monitoring station to confirm the transmission. Perform additional transmissions required by the monitoring station. Check the Trouble light on the keypad. If it is on, press [D] then [2] to determine if there is a system trouble. The Trouble Display section in Keypad Commands gives a description of the different trouble conditions. Instructing End-User Fill out the system reference guide in the PC2550 Instruction Manual. Check off sections in the manual which apply to the users system and make additional notes if necessary. Describe the system to an authorized user. Describe arming and disarming procedures. Describe the basic keypad functions. Assist the user in working through examples of each type of command. Provide user(s) with the Instruction Manual and instruct them to read the manual to become familiar with the system operation. Instruct the user to test the system on a regular basis as described in the Instruction Manual. The Master Code should be changed from the default setting and recorded in the Instruction Manual.

GUIDELINES FOR SMOKE DETECTOR LOCATION
Experience has shown that all hostile fires in family living units generate smoke to a greater or lesser extent. Experiments using typical fires in family living units indicate that detectable quantities of smoke precede detectable levels of heat in most cases. For these reasons, NFPA standard 74 requires smoke detectors to be installed outside of each sleeping area and on each additional story of the family unit. The following information is for general guidance only and it is recommended that NFPA standard 74 be consulted and that the smoke detector manufacturer's literature be used for detailed installation instructions. It is recommended that additional smoke detectors beyond those required be installed for increased protection. The added areas include: basement, bedrooms, dining rooms, furnace room, utility room and hallways not protected by the required detectors.

FIG. 2: In the family living units with more than one sleeping area, a smoke detector should be located to protect each sleeping area.
FIG. 4: Smoke Detector mounting - Dead Air Space. The smoke from a fire generally rises to the ceiling, spreads out across the ceiling surface and begins to bank down from the ceiling. The corner where the ceiling and wall meet is an air space into which the smoke may have difficulty penetrating. In most fires, this dead air space measures about 4 in. (0.1m) along the ceiling from the corner and about 4 in. (0.1m) down the wall as shown in Figure 4. Detectors should not be placed in the dead air space.

KEYPAD FUNCTIONS

Introduction
The PC2550RK remote keypad provides complete information and control of the PC2550 control panel. The panel can be fully programmed from the keypad. The 8 zone lights and the fire alarm light provide alarm and status indication for the alarm circuits. The 6 function lights guide the user in operating the system. The built-in buzzer lets the user hear correct key entries and other alert signals. The 12 digit keypad is used for code entry and other programming functions. All keypad entries are made by pressing one key at a time. The keypad is normally resting in the arm-disarm mode. In this condition the zone lights are indicating the opening and closing of zones. The Ready light comes on when all zones are closed. The system can be directed to perform other functions such as zone bypassing, displaying trouble conditions, displaying alarm memory and programming by entering one of the various [D] commands described below. Pressing the [#] key or not making any key entry for 2 minutes always returns the keypad to the arm-disarm mode. Programming [D][8] Command section for instructions on how to change the exit time. Also see, Quick Arm and At Home Arming.

The auto-arm will be attempted at the same time the following day. Any time an auto-arm is aborted using one of the above methods, the reporting code programmed in section [08] will be transmitted to the central station. When the panel does arm by auto-arming, any open zones will be Force-armed. If light 5 in section [18] is on, the panel will send a partial closing code to let the central station know zones were bypassed. If section [16] light 1 is on, the zones that were force-armed will be identified by transmitting their alarm code along with the partial closing code.

Quick Arm

[D]+[6]+[MASTER CODE]+[4] The Quick Arm feature is enabled by pressing the [4] key while in the User Functions Command section. When enabled (enabled 3 beeps.disabled one long beep) the panel can be armed by entering [D][0]. The closing code transmitted for Quick Arm is the same as the code which is programmed for the Master Code.
Do not use the installers test when the panel is partially armed.

Auto-arm Enable

[D]+[6]+[MASTER CODE]+[5] Entering [D] [6] [Master Code] [5] will enable/disable the auto-arming feature. When the feature is being enabled, the keypad buzzer will sound 3 beeps and when being disabled the buzzer will sound one long beep. Note: Auto Arm must be disabled on UL Listed systems.

Setting the Clock

[D]+[6]+[MASTER CODE]+[1] Setting the System 24 Hour Clock (item [1]) tells the system the correct time of day. If the system is without battery and AC power it cannot continue to keep time. Therefore when the panel is first powered up or when it has been without AC power long enough to completely discharge the stand-by battery, the System 24 Hour Clock must be reset. If the time needs to be reset a Trouble #8 will be indicated on the keypad (see [D][2] System Trouble Command). If a printer is attached to the panel, setting the clock must include the day, month and year. e.g. HH: MM: DAY: MONTH: YEAR.

Door Chime

[D]+[6]+[MASTER CODE]+[6] The Door Chime feature is enabled by pressing the [6] key while in the Users Functions Command section. When enabled the keypad buzzer will beep quickly 5 times each time any zone defined as a delay or instant circuit opens or closes. The Door Chime feature does not operate on other zone definitions. Zone bypass may be used to eliminate beeping on doors where it is not wanted. This feature operates only while the panel is disarmed.

Auto-arm Time of Day

[D]+[6]+[MASTER CODE]+[2] Note: Auto-arm cannot be used for UL installations. The PC2550 can be programmed to arm at the same time each day. Programming item [2] sets this time and the feature must be enabled as shown in item [5] (see Autoarm Enable on this page). At the selected auto-arm time the keypad beeper begins to sound and the Bell/Siren will pulse once every 10 seconds to alert anyone on the premises that the system is about to arm. The Bell/Siren pulse can be silenced in section [17] by turning light 1 on. The keypad beeper will sound for one minute before autoarming unless one of the following two methods is used to abort the auto-arm. Auto-arm abort: Any key can be pressed to abort the auto-arm sequence and silence the keypad during the one minute pre-alert (this is the default condition). Auto-arm abort with code: If section [17] light 4 is on, then a valid 4 digit access code is required to abort the auto-arm sequence.

Note: the time of day, day, month and year must be programmed into the panel using the [D]+[6]+[Master Code]+[1] command as described on page 10.

DOWNLOADING

The PC2550 supports the DSC downloading package. See the downloading manual for details on specific capabilities. There are several sections pertaining to the downloading feature which must be programmed. Section [27] - Downloading Access Code A four digit code must be programmed into this section to allow access to the control panel by the downloading computer. Section [28] - Panel Identification Code A four digit code must be programmed into this section to allow the downloading computer to identify the panel it is communicating with. Section [46] - Downloading Computer Telephone Number If Callback is enabled, section [47] zone light [8], then this section must be programmed with the telephone number of the downloading computer. Section [47] - Modem Configuration machine defeat option (Answering Machine Over-ride). Downloading and Answering Machine The PC2550 software provides a means to handle downloading when an answering machine is also connected to the telephone line. In section [47], if zone light 7 is off, it is assumed that there is no answering machine connected to the telephone line and the panel will capture the line after the set number of rings. If zone light 7 is off and an answering machine is connected and it is set to answer before the panel, the panel will be unable to receive a call from a downloading computer. If the panel is set to answer before the answering machine, the answering machine will be unable to receive incoming messages. If zone light 7 is on and the panel is called for 1 or 2 rings only and then called again within a set time of 1 to 249 seconds (set in section [49]), the panel will then answer the second call on the first ring (Answering Machine Over-ride Timer). Once the panel is connected to a downloading computer, no [D] functions can be performed. If the [D] key is pressed while the panel is connected to a downloading computer, the keypad buzzer will sound one long tone to indicate an error.

[02] 1st Account Code

The 1st account code is always transmitted to the 1st phone number to identify the alarm customer. After entering the Section number [02], enter a 4 digit number. If HEX digits A to F are required; enter [D], [1].[6] and [D] again to return keys to normal decimal entry. Where a zero digit in the account code is required use HEX A ([D][1][D] to transmit 10 pulses. The receiver at the monitoring station interprets 10 pulses for a digit as a zero. If a three digit code is required as in 3/1 formats, enter [0] as the last digit. [0] represents a null digit.no pulses transmitted.

[03] 2nd Phone Number

This is the second telephone number to which the communicator will dial. See section [01] 1st Phone Number for programming instructions.

[04] 2nd Account Code

The 2nd account code is always transmitted to the 2nd phone number. See section [02] 1st Account code for programming instructions.
Reporting Codes Explanation
Sections [05] to [13] are used to program the communicator reporting codes. A reporting code is transmitted along with the account code with each transmission. If the reporting codes are not programmed in these sections no transmission will be sent when an event (i.e. alarm, restoral, opening/closing, trouble etc.) takes place. To prevent a transmission from being sent for any event in the following sections leave it unprogrammed or enter [00] as the reporting code. Between 6 to 10 reporting codes are programmed in each section. Once the section number is entered, the keypad expects 6 to 10 two digit numbers to be entered for the number of reporting codes in that section. The keypad beeps twice and the armed light flashes after each 2 digit number is entered. After the last code is entered, programming of the current section is complete. The keypad will beep 5 times, the Ready light will go off and the Armed light will go on. The keypad is then ready to accept the next section number for programming. When changing the reporting codes in a section, only code entries up to the one which is being changed need to be entered. Press [#] to exit from the programming sequence. Only codes up to the last one entered will be changed.

DATA = 1900 Hz KISSOFF = 1400 Hz SPEED = 10 BAUD 20 BPS is the standard fast format used on DCI, Franklin, Sescoa and Vertex receivers. DATA = 1800 Hz KISSOFF = 2300 Hz SPEED = 20 BAUD Radionics Format For conventional 3/1 Radionics format the communications mode should be set to either Radionics rounds [B] or Radionics parity [C]. The extended version of the Radionics format is normally used. The following guidelines have been provided to help in configuring the PC2550 for Radionics format. 1.The customer account code must be only 3 digits with a zero making up the 4th digit (i.e. program 1230 for account code 123). 2.The zone alarm reporting codes must all be single digit numerical codes with no extended 2nd round being sent. The zero in the 2nd digit of the reporting code tells the PC2550 not to send an extended round. 3.All other non-alarm reporting codes must be set up to send an extended 2nd round. The 1st digit of the reporting code is used to identify the event while the 2nd or extended digit is used to associate the event with a particular item. (i.e. A reporting code of E3 means restore zone 3. E for restore and 3 for zone 3.) 4.The following is a list of 1st digit identifiers that should be used with the Radionics format. Restorals E Example E3= Restore Zone 3 Openings B Example B2= Opening by User 2 Closings C Example C4= Closing by User 4 Troubles F Example F5= Trouble from Source 5 Misc D Example D1= Partial Closing Sescoa Super Speed Format The Sescoa Super Speed Format must be programmed exactly as follows to function correctly. 1.The account code must be four decimal digits in length and in the range of 0001 to 3374. 2.The reporting codes must be 2 digits in length and programmed as follows. Alarms Zones 1-8 (section [05]) A1 to A8 Restorals Zones 1-8 (section [06]) A1 to A8 All Opening Codes (sections [09] and [10]) BA All Closing Codes (sections [07] and [08]) CA Partial Closing (section [07]) C1 Low Battery (section [12]) E1 Battery Restorals (section [13]) E1 AC Failure (section [12]) E1 AC Restoral (section [13]) E1 Bell CCT.

Formats [5] and [D] are compatible with the Sescoa model 3000C receiver. For UL installations, ensure that the control unit is reporting to one of these receivers.
[30] Programmable Input and Output Options
Both the Auxiliary Input Zone and the Programmable Output have options which are programmed in this section. After the section number [30] is entered, enter 2 HEX digits from the following lists to program them. Auxiliary Input Zone (1st digit) [0] Printer attached to panel (see Note 1) [1] Silent 24 hour input * [2] Audible 24 hour input [3] Momentary arming input * Not allowed for UL local installations. See Auxiliary Input Terminal in the Terminal Connections section on page 4 for details on the Auxiliary Input. When option [3] is selected, a momentary key closure between the Auxiliary Input and the Positive Auxiliary Power Supply will alternately arm and disarm the system.
