Description
The Napco Firewolf FW-2 advanced photoelectric smoke detectors utilize two bi colored LEDs for indication of status. In a normal standby condition, the LEDs will flash green every 3 seconds. When the detector senses that its sensitivity has drifted outside the UL Listed sensitivity window, the LEDs will flash red every 3 seconds. When the detector senses smoke and goes into alarm, the status LEDs will latch on red.
