PHOTO SPOT SMOKE Product Details
The F220 photoelectric smoke detectors are UL listed, open-area photoelectric smoke detectors. Use them with commercial fire protective signaling systems and household fire warning systems. These smoke detectors scatter light using a pulsed infrared source operating with a gated, high-speed, photodiode infrared sensor. The symmetry of the optical chamber allows 360° uniform smoke entry, but minimizes external light entry. The detectors use low current electronic circuitry, so they can connect to 12 VDC nominal or 24 VDC nominal power source circuits.
