Bosch F220-PTH Fire & Intrusion Detector

The Bosch F220-P Photoelectric Smoke Detector uses the light scatter technique using a pulsed infrared source operating with a gated high-speed photodiode infrared sensor and a symmetrical optical chamber that allows uniform 360-degree smoke entry while increasing immunity to external light. Head only; needs base. The F220-P detectors are UL Listed, open-area Photoelectric Smoke Detectors designed for use with commercial fire protective signaling systems and household fire warning systems (refer to NFPA 72, The National Fire Alarm Code). By utilizing low-current electronic circuitry, the F220-P detectors can be connected to a wide range of power source circuits.

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 (see NFPA 72, the National Fire Alarm Code). 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.
