Product Details

The EVC-H-A2S heat detector is an elegantly designed, aesthetic, low-profile detector which blends unobtrusively into modern working environments. The detector incorporates the OMNIVIEW™

360. LED alarm indicator with the facility to activate a remote indicator unit. The EVC-H-A2S is a thermistor-based conventional heat detector, which uses electronic components that change their resistance when heated; this change is detected by circuitry within the detector. The detector EVC-H-A2S has an operating range of 54 – 70°C.

BASE Options

UB-4SD – Standard profile mounting base with a schottky diode for head removal fault monitoring.

Note – Not compatible with the Protec 3000 and 6000 range of bases.
