Addressable Multi Smoke & Heat Detector FD 7160
FD7160 Addressable Multi Smoke & Heat Detector is mainly designed to react up on a fixed smoke concentration level, or upon a specific heat level (temperature level), and to provide early warning of a fire condition.
The functionality of the optical part is based upon the caused distraction of infrared rays within the smoke chamber when smoke particles enter it. In meanwhile, the functionality of heat part depends on the temperature changes which cause ohmic resistance alteration in the thermistor.
The 3 levels of smoke concentration needed to activate the detector are (low, middle and high). Another 3 heat classes needed for activation are (A1R, A2R, and BR), all levels are programmable via Fire Control Panel IFS 7002 using UniTALK which is a specialized communication protocol. It features built in short circuit isolator, and the circuit board and the optic are mounted within the plastic body.
It offers 2 LEDs, offering 360° visibility, light to indicate the following:
– Duty Mode – when both LEDs flash repeatedly every 16 seconds.
-Fire condition – when both LEDs light constantly.
-Activated isolator- when both LEDs flash repeatedly with 1Hz frequency.
-Short circuit at the remote indicator output- both LEDs flash repeatedly with 2Hz frequency.
-Necessary service-both LEDs flash repeatedly with 2Hz frequency
