Wired Smoke Alarm Dc12v/24v Networking Smoking Detector Switch Fire Alarms Detectors Sensor Description

Wired Smoke Alarm DC12V/24V Networking smoking Detector Switch Fire alarms detectors Sensor
Features
This product is a non-coded smoke detector with a pair of switch output contacts, which can be normally open or normally closed according to actual needs. During normal operation, the indicator light flashes once every 8 seconds: when an alarm occurs, the indicator light is always on, and the alarm output contact operates at the same time.
Power-off reset/automatic reset optional
Common reporting output NC/NO optional
9/35V non-polar wide voltage input (AC, DC)
Network output/LED indication alarm/Buzzer sounding alarm
SMT process manufacturing, strong stability
Low quiescent current to save power
Dust-proof, insect-proof. Anti-white light interference design
Metal shield, anti-RF interference (20V/m IGiiz)
