Intrinsically Safe Conventional Photoelectric Smoke Detector

Operating Voltage :16VDC～28VDC
Static Current: ≤60μA (Note: In standby state, the detector can work within 16VDC~28VDC)
Alarm Current: ≤30mA (Warning: The alarm current depends on the current limit of the FACP. It’s not allowed to power the detector directly by 24VDC. Otherwise the detector
will be blown as a result of without current limiting resistor.）
Maximum Ripple Voltage :4V (peak-to-peak)
Alarm Reset: Instantaneous Power-off (5s Min，2.5VDC Max)
Power-up Time :≤10s
Alarm Indicator: Red Flashes (2s~4s) in normal condition. Illuminates when fire is reported.
