Blue Line ISM-BLQ1 Quad Passive-infrared Detector
The ISM-BLQ1 Quad PIR Detector uses two individual sensors that operate like two PIRs in one. Each sensor processes signals sepa-rately. Both must activate to cause an alarm. This increases reliabil-ity, because false alarm sources such as noise spikes and small animals are ignored. Quad detectors combine an unsurpassed level of catch performance with the highest level of false alarm immunity. Therefore, they are particularly well suited for challenging installation situations; for example, cases where cross catch of intruders cannot be guaranteed or where intruders are able to cross the detection pattern very quickly.
