Edwards Signaling 439D-6AW-R SF 25/11 Environmental Sensors

Environmental Sensors

A short circuit causes the module to inhibit the activation of the audible/visual signal circuit so the riser is not connected to the wiring fault

potentially saving precious rescue time while also reducing property damage

The horn output of horn strobes can be independently controlled on 2-wire circuits using the Wheelock patented sync protocol

When the detector senses that its sensitivity has drifted outside the UL listed sensitivity window the LEDs will flash Red every 3 seconds

Edwards Signaling 439D-6AW-R SF 25/11 Environmental SensorsEdwards Fire Alarm Bells are specially designed for fire alarm applications. The gongs are made of selected alloy steel to give the loud, resonant tones necessary in fire alarm systems. Two gong sizes are available to overcome different ambient noise level. The Fire Alarm Bells are of the underdome type with heavy duty mechanisms. Each bell is supplied with a mounting plate that fits any standard single gang opening (see Installation Data). For
