Securiton D-LIST Line Type Heat Detector
The ASD 535 continuously aspirates air through a sampling pipe installed in the monitored rooms or premises and conveys it to the smoke sensor. This sensor, equipped with new HD (High Dynamic) technology, checks the air for smoke particles with an unsurpassed level of precision. If the preset particle threshold is exceeded the detector immediately sends an alarm signal to the fire alarm system. Thanks to this early warning system, an incipient fire is nipped in the bud before it has time to develop any heat. The Securiton ASD range is fully certified to EN, CE, UL, FM and VDS standards.
