ASD531 is an high sensitivity active smoke detector with 1 pipe for aspirating smoke detection. It features a on-board detector with 0,02%/m – 10%m alarm threshold. It’s used whenever point-type detection is not possible due to adverse environment (temperature, dust) or due to malfunctioning (maintenance difficulties, false ceiling...).
It is based on an analysis control unit (ASD531) that, thanks to the integrated sensor, takes a sample of the aspirated smoke from the tubes in the system. For setting and programming of the system is necessary the ASDCONFIG software (not supplied).
ASD531 is VdS approved and CPR 305/2011 certified (ex CPD 89/106/CEE certification), EN54-20.
