Description

The Bosch F220-P is a white detector head. This device does not have a built-in heat sensor or carbon monoxide detector. Also, the Bosch F220-P 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).

Furthermore, 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.

A dual-color LED indicator flashes green every 8 sec when the detector has power and the smoke sampling circuitry is working. If CleanMe is enabled, the green LED double flashes (two flashes a half second apart) every 8 sec to indicate normal operation. In addition, the LED turns red if an alarm is sent. After the alarm condition clears, reset the detector by interrupting its power. If the chamber becomes contaminated beyond its ability to compensate, the green LED flashes every 4 sec to indicate trouble.
