Firewolf Advanced Photoelectric Smoke & Heat Detector, 4-Wire
Back Two Sensors In One! The Napco 4-wire smoke detectors more accurately detect all types of fires for performance superior to previous photoelectric detectors. They come in attractive, low-profile, baseless units with dual LEDs for excellent visibility. The detectors are 100% burn-in tested Enable precision detection of even minute particles. Low profile – only 1.8" high Includes built-in thermal heat sensor – for more accurately detecting a wide range of fires (135°F heat detector) 4-wire model Highly stable operation, RF/transient protection Two built-in power/sensitivity supervision/alarm LEDs Non-directional smoke chamber Vandal resistant security locking feature Built-in magnetic go/no go detector test feature Removable smoke labyrinth for cleaning or replacement Automatic Sensitivity window verification function meets outlined requirements in NFPA 72, Chapter 7, Inspection, Testing and Maintenance Operation Firewolf advanced photoelectric smoke detectors utilize two bicolored 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. The unit is comprised of an LED light source and silicon photo diode receiving element. In a normal standby condition, the receiving element receives no light from pulsing light source. In the event of fire, smoke enters the detector and light is reflected from the smoke particles to the receiving element. The light received is converted to an electronic signal. Signals are processed in the comparator, and when two consecutive signals exceeding the basic level are received within a specific period of time, the time delay circuit triggers the SCR switch to activate the alarm signal. The status LED lights continuously during alarm period.
