Installation/Configuration Notes

Compatibility Information

Four‑wire: Compatible with all UL Listed four‑wire control panels. Refer to the control panel's Installation Instructions for proper end‑of‑line (EOL) resistor selection.

Detectors: Compatible with the following F220 Series Detector Heads:

•F220‑P Photoelectric Smoke Detector

•F220‑PTH Photoelectric Smoke Detector with +135°F (+57°C) Heat Sensor

•F220‑PTHC1 Photoelectric Smoke Detector with +135°F (+57°C) Heat Sensor and Carbon Monoxide Sensor Enhancement1

•F220‑135 Electronic Rate‑of‑Rise, Fixed Temperature +135°F (+57°C) Heat Detector

•F220‑135F Electronic Fixed Temperature +135°F (+57°C) Heat Detector

•F220‑190F Electronic Fixed Temperature +190°F (+88°C) Heat Detector

1The F220‑PTHC detects carbon monoxide (CO) as a component of a fire. It is not a CO detector and cannot activate an alarm in the presence of CO only.

Mounting Considerations

Depending on local regulations, surface mount the bases using anchors, mollies, or wing nuts, or mount directly on four‑inch square or octagonal electrical boxes or single‑gang switch boxes.

Note The electrical box must be large enough to accommodate the number and size of conductors specified by the National Electrical Code or any local authorities having jurisdiction (AHJ).

Wiring Considerations

In a four-wire system, the maximum loop length and number of bases that can be placed on a loop depend on the voltage drop on the power circuit. Use standard voltage drop calculations to ensure that the last detector on the loop has at least 16 V when all sounders and relays are powered.
