Series 65 Optical Smoke Detector – Flashing LED & Magnetic Test

55000-315APO

The Series 65 Optical Smoke Detector incorporates a pulsing LED located within the housing of the detector. The external detector moulding is identical to that of the ionisation detector, and has an indicator LED which is clear in quiescent state but produces a red light in alarm.

Responds well to slow-burning, smouldering fires
Well-suited to bedrooms and escape routes
Unaffected by wind or atmospheric pressure
Flashing LED and magnet operated test switch option
