The Faraday 8702 is a single-input addressable interface module that supervises one normally open or normally closed dry contact device — such as a flow switch or tamper switch — and reports its status directly to the fire alarm control panel over the addressable device circuit. A tri-color LED on the module indicates red for alarm, yellow for trouble, and green for normal operation, and the module is field-addressed with the Faraday 8720 Device Programmer/Tester before installation.
Key Features
- Monitors a single normally open or normally closed supervised dry contact
- Tri-color status LED: red (alarm), yellow (trouble), green (normal)
- Polarity-insensitive wiring — Line 1 and Line 2 can be either line of the loop
- Field-addressed with the Faraday 8720 Device Programmer/Tester
Technical Specifications
- Current Draw: 1 mA from the addressable device circuit
- Supervised Switch Rating: 27 VDC max, 3.5 mA during polling, 10 ohms max contact resistance
- Maximum Cable Length: 200 feet of 18 AWG wire to the supervised switch
- Mounting: 4" square, 2-1/8" deep box, or double-gang box (user supplied)
