F220-P - Bosch SMOKE DETECTOR HEAD

The F220 Photoelectric Smoke Detectors are ULListed, open-area photoelectric smoke detectors. Usethem with commercial fire protective signalingsystems and household fire warning systems (seeNFPA 72, the National Fire Alarm Code). These smokedetectors scatter light using a pulsed infrared sourceoperating with a gated, high-speed, photodiodeinfrared sensor. The symmetry of the optical chamberallows 360° uniform smoke entry, but minimizesexternal light entry. The detectors use low currentelectronic circuitry, so they can connect to 12 VDCnominal or 24 VDC nominal power source circuits.
