The Discovery Aspirating Smoke Detector [ASD] is a point based professional air sampling unit, combining 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.
Air is drawn from the protected area through one or two perforated 25mm pipes per channel. A powerful fan together with sophisticated air-flow monitoring and control circuitry ensures that transport delays are minimised and air-flow is kept within working limits. System status and flow control is continuously displayed, with on-board fault relays allowing remote fault monitoring of each channel.
- EN54-20 Approved
- Available as a single [ASD-1] sampling unit or dual [ASD-2] sampling unit
- Uses the Discovery Optical Analogue Addressable Detector
