Discovery Aspirating Smoke Detector – Single Point

29650-081APO

The Discovery Aspirating Smoke Detector (ASD) is a point based professional air-sampling unit, designed to complement analogue addressable system technology. It combines standard field serviceable smoke detectors with a stand-alone air sampling solution to provide protection of difficult to access, environmentally demanding, aesthetic or architecturally restricted areas.

EN 54-20 approved
Available as a single (ASD-1) sampling unit or dual (ASD-2) sampling unit
Uses the Discovery Optical Analogue Addressable Detector
Addressable monitoring of fail-safe fault relays
The ASD can be installed up to 50m away from the sampling point
IP65 rated enclosure
