DSX Analog Door Box

P/N 922450 At a Glance
Requires 2PGDAD Module connected to DSX Digital Station (16ESIU) PCB. DSX-80/160: No built-in Door Box ports.

The Analog Door Box is a self-contained Intercom unit typically used to monitor an entrance door. A visitor at the door can press the Door Box call button (like a door bell). The Door Box then sends chime tones to all extensions programmed to receive chimes. To answer the chime, the called extension user just lifts the handset. This lets the extension user talk to the visitor at the Door Box. The Door Box is convenient to have at a delivery entrance, for example. It is not necessary to have company personnel monitor the delivery entrance; they just answer the Door Box chimes instead. Tips to remember: The Analog Door Box is a weather-tight unit and can be mounted outside. The maximum number of DSX Analog Door Boxes you can install is determined by the number of 2PGDAD Modules, which in turn is limited only by the availability of 16ESIU station ports.

System Conguration

DSX-80/160 System Load Factor
The combination of lines and extensions you can connect to your DSX system may be limited by the System Load Factor. Use the DSX-80/160 System Load Factor Worksheet on the next page to verify your systems conguration. When entering data on the worksheet, for each installed card make entries for each Load Type. There are two Load Types to consider: 5 VDC and 40 VDC. To check your system conguration: 1. Indicate the quantity for each card installed in the Qty column. - The number of keysets, single line sets, and DSS Consoles does not affect the load factor. 2. For each item and for each Load Type, multiply the Qty times the Load and enter the value in the Total column. - For example, two 16ESIU Cards have a load of 16 for 5 VDC and 40 for 40 VDC. 3. Add up the entries in each Total column and enter the values in Item 1: Load Type Totals. 4. Review Item 2: Power Supply Capacity and determine the capacity of the power supplies installed in your system.

5. Compare the capacities in Item 2 to your entries in Item 1. Item 1 must always be equal to or less than the entry in Item 2. Important Do not operate your system if the total for either Load Type exceeds the Power Supply Capacity of your installation.

Powering Up the System

Before Powering Up
The systems built-in Automatic Slot Conguration automatically sets up station and line cards when you initially power up the system. On power up, the system scans the cards from left to right and sets up the station and line numbering as follows: Extension numbers will begin with 300 in the rst slot and increment from left to right. Line numbers will begin with 101 (starting from the rst installed COIU or T1/E1/PRI Card) and will also increment from left to right. For example, in a 16x32, the numbering will be: 1st 16ESIU Card = Extensions 300-315. 2nd 16ESIU Card = Extensions 316-331. 16COIU Card = Lines 101-116. In addition, the system will also automatically set up a station or line card when you plug it in hot. To power up the system: - You do not need to reattach the right side panel before powering up the system. Leaving the right side panel removed makes the station and line cabling more accessible. 1. Make sure the system is properly grounded and the card bracket is reinstalled and secured. 2. Install a surge protector in the AC outlet you intend to use for system power. 3. Plug the main cabinets AC power cord into its surge protector. 4. Turn on the main cabinet power switch. After about 30 seconds, verify the system LEDs.
