The optical smoke detector SD-280

code: SD280
Optical smoke detector, relay output, connectable to binary input, powered from 12Vdc.

The SD280 detector combines an optical smoke sensor with a heat sensor. Both sensors have their outgoing signals processed digitally, resulting in higher false alarm immunity.

When the detector is used with inserted batteries (3x 1.5 V AA), it can continue operating as a stand-alone detector, when the external 12 V power supply is disconnected.

For application with M13xx Multiloggers please see pdf Manual for connection of detectors in the Download folder.
