Napco Security FW-2 2 Wire Photo Electric Smoke 12/24V

Napco Security Alarm FW-2 2 Wire Photo Electric Smoke Detector is designed to provide reliable fire detection in a compact profile. Measuring just 1.8 inches high, this advanced device uses two bi-colored LEDs to indicate its operational status. In normal conditions, the LEDs flash green every three seconds; however, if the sensitivity drifts outside the UL Listed sensitivity window, they will flash red. Upon smoke detection, the LEDs will latch on red, ensuring immediate visibility of the alarm status. This smoke detector features a non-directional smoke chamber and a built-in thermal heat sensor for enhanced accuracy in detecting various fire types, with a triggering temperature of 135°F. Its vandal-resistant security locking mechanism provides additional peace of mind, while the automatic sensitivity window verification guarantees compliance with NFPA 72 standards. The FW-2 operates on a nominal voltage of 12/24 Vdc, with a maximum working range of 8.0-35.0 Vdc. It also includes a removable smoke labyrinth for easy cleaning and maintenance. Whether you're a building professional or a safety-conscious homeowner, the Napco Security Alarm FW-2 ensures you are adequately protected against fire hazards while maintaining a sleek and unobtrusive presence in your space.

2 Wire Photo Electric Smoke 12/24V

The 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.
