The 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.
