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
the bases directly on four‑inch square or octagonal
electrical boxes or single‑gang switch boxes.
Notice
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 two‑wire system, the maximum loop length
depends on the number of detector bases on the loop,
the wire size, and the control panel specifications.
Refer to the control panel's installation instructions for
specific wiring information.
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 10 V.
