F220 Heat Detectors
- Two-wire or four-wire bases
- 50 ft (15.2 m) maximum spacing between detectors
- Visible identification of model: F220‑135 = no ring, F220‑135F = gray ring, F220‑190F = black ring
- Tamper detection
- Dual color LED
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.
