The F220 Heat Detectors include:
• F220‑135: An electronic rate-of-rise, fixed
temperature heat detector that initiates an alarm
when the ambient temperature exceeds +135°F
(+57°C) or when the ambient temperature increases
by +15°F (+8.3°C) or more in less than 1 minute
when the ambient temperature exceeds +135°F
(+57°C) or when the ambient temperature increases
by +15°F (+8.3°C) or more in less than 1 minute
• F220‑135F: An electronic fixed temperature heat
detector that initiates an alarm when the ambient
temperature reaches +135°F (+57°C).
temperature reaches +135°F (+57°C).
• F220‑190F: An electronic fixed temperature heat
detector that initiates an alarm when the ambient
temperature reaches +190°F (+88°C).
temperature reaches +190°F (+88°C).
The detectors use low current electronic circuitry, so
they can connect to 12 VDC nominal or 24 VDC
nominal power source circuits. When mounted on the
appropriate F220‑B6 Series Mounting Base, the F220
Heat Detectors provide general property protection
from fire.

Dual-color LED
To verify the detector has power and the heat
detection circuitry functions, a dual-color LED
indicator flashes green every 8 sec when operating
normally. It flashes once every 4 sec when a trouble
condition exists. The LED latches on red if an alarm
