GENERAL INFORMATION
This module adds up to 8 end-of-line resistor supervised zones to compatible control/communicators via the control’s keypad wiring.
The module may be mounted within the control’s cabinet (if room permits), or remotely. If mounted remotely, there are provisions to tamper protect the unit. Communication to the module is supervised so that it cannot be disconnected from the keypad wiring without detection by the control. If the wiring is cut, a tamper or alarm signal will result, to indicate that this device (and possibly other similarly connected devices) has become inoperative.
INSTALLATION
When the module is to be mounted inside the control’s cab- inet, it should be mounted horizontally. Insert self-tapping screws (provided) in two adjacent raised tabs at the back of the cabinet.
Leave the heads projecting 1/8”. Hang the module on the screw heads via two of the slotted holes on the back of its housing. In this case, the module’s cover need not be tamper protected. If the tamper jumper (see the diagram) is placed in its upper position, the module’s cover can be left off.
When the module is to be mounted remotely, holes at its rear permit it to be mounted horizontally or vertically. Wires can exit from the side or the breakout on the back of its housing.
The tamper jumper should be put into its lower position and, when the installation is completed, the unit’s cover put on. A magnet in the cover, positioned near a reed switch in the unit, will cause a tamper signal to be sent to the control if the cover is removed.
CONNECTIONS AND SETTINGS
See the table below and the diagram on the other side. Make protection zone connections to 12-position terminal block TB1. Each zone that is used must have a 1000 ohm end-of-line resistor connected across the end of its loop, as shown.
If a zone is not programmed, the resistor need not be used. The method of programming each zone for type of alarm and reporting code to the central monitoring station varies with the control to which the module is connected. Refer to the in-stallation instructions for that control unit.
Set the DIP switch to one of 16 addresses, as shown in the table below, so the control can identify the module and com- municate with it properly. The address to be set is determined by the particular control to be used, and the control’s installation instructions must be consulted. As shipped, the DIP switch is set for an address of “0”.
Zone A can be set for a fast response time of 10ms to an open circuit, if desired, by setting position 1 of the DIP switch to “OFF”. As shipped, it is set to “ON” for a response time of 300ms, as shown in the table below. All of the module’s other protection zones have a nominal response time of 300ms. Connections to the control’s keypad wiring points can be made via 4-terminal block TB2, the 4-pin plug, or both (wire color connections are the same).
