INSTALLATION INSTRUCTIONS AND WIRING FOR
ADDRESSABLE INTERFACE MODULES
INTRODUCTION
The 8702/8703/8704 Addressable Modules, shown in Figure 1, interface
normally open contact devices to an Addressable Device Circuit of a fire alarm
control unit.
The 8702 and 8704 can monitor a normally open or closed dry contact. The
8702 can only monitor and report the status of the contact, while the 8704
incorporates an addressable Form C relay. The 8703 is a dual input module that
supervises and monitors two sets of dry contacts.
A multicolor LED, visable through the cover plate, indicates the condition of the
initiating device circuit. This multicolor LED displays red for alarm, yellow for
trouble and green for normal operation.
PROGRAMMING INSTRUCTIONS
Refer to Figure 2 to locate the opening on the module cover that allows
access to the programming holes which are on the module printed circuit
board.
To prevent potential damage to the 8720 DO NOT connect a module to
the 8720 until at least one wire is removed from terminals 1 or 2 of the
module.
1. Plug the programming cable of the Faraday 8720 Programmer/Tester
into the two-pin receptacle on the module. (See Figure 2 for location.)
2. Set the address for the module by following the instructions in the 8720
Programmer/Tester Manual (P/N 315-033260FA). Refer to Figure 3 for
setting normally open and normally closed switches.
3. Record the device address on the label located on the module. The
module can now by installed and wired to the system.

NOTES:
1. There can be any number of normally closed or normally open switches.
2. The end of line resistor must be located at the last switch for normally open switches.
3. Do not wire a normally closed switch across the end of line resistor.
4. Only for use with status applications.

- Page 1 Addressable Device Circuit of a fire alarm control unit. The 8702 and 8704 can monitor a normally open or closed dry contact. The 8702 can only monitor and report the status of the contact, while the 8704 incorporates an addressable Form C relay.
- Page 2 MOUNTING (Refer to Figure 4) Addressable Interface Models 8702, 8703, and 8704 mount directly into a (user sup- plied) double gang or 4 inch switchbox. Fasten the module to the switchbox with the switchplate using the 2 screws provided. A red LED will blink to indicate an off-normal input switch position and/or an internal relay transfer.
- Page 3 NOTE: Terminal 5 of the module must be connected to a known good earth ground for proper operation. EOL device must be a 470 ohm, 1/4 W resistor. When replacing an existing 8702/8703/8704 on a device loop, you must also replace the EOL resistor if it is not 470 ohms, 1/4W.
