Smoke Detectors

Firewolf’s photoelectric smoke detectors use bicolored LEDs for indication status. In normal standby mode, the LEDs flash green every three seconds. When the sensitivity drifts outside the UL-listed sensitivity window, the LEDs flash red every three seconds. When the detector senses smoke, the LEDs will latch on red. The device more accurately detects all types of fires, including paper, wood, gasoline, polystyrene and smoldering fires. The chamber design reduces unwanted chamber reflections.
