Bosch F220-135 Heat detector head, fixed heat (135°F)

CTN: F220-135F | Product No.: 4.998.125.339

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.
• F220?135F: An electronic fixed temperature heat detector that initiates an alarm when the ambient 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).

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.
