820 photoelectric smoke alarm network switching output ceiling installation dedicated cabinet

Specifics:

Detail:

 9-35V wide voltage design normally open and normally closed output networking Insect original design of industrial-grade metal shield to meet the needs of high-end customers.

Features

     This product is non-coding smoke detectors, having a pair of switch output contacts, according to the actual need to select normally open or normally closed output. During normal operation, the indicator flashes once every 8 seconds, alarm, indicator light, alarm output contact while it is operating.

  Power reset / automatic reset option

  Promise of Power Input
