Optical Smoke Detectors are used for thermal assistance to the core photoelectric smoke detector to give enhanced false alarm immunity and faster response to a wide range of incipient fires. The plug-in unit combines two separate sensing elements that are managed by embedded software to act as a single unit. The thermal detection function combines thermistor technology with a software corrected linear temperature response. In areas where the normal daytime activities may potentially create unwanted alarms, the detector can be programmed to operate in a “heat only” mode, automatically reverting to full photo-thermal operation during unoccupied periods. Features & Benefits:
New mechanical platform with revolutionary chamber
Includes Schneider Electric protocol
Available with or without single pole short circuit isolation with status control through the Schneider Electric protocol
Tri colour LED offering red, green and amber colours
Rotary decade address switches
Pure white colour to compliment modern buildings
100% mechanical and electrical backwards compatibility
New Base design to compliment the detector
