The detector has a tamper-
resistant feature that prevents
removal from the mounting
base without the use of a
tool.
To engage, cut the small
plastic tab located on the
mounting base (Figure 3),
and then install the detector.
To remove the detector head,
use a small screw driver to
depress the square tamper
release tab on the skirt of the
mounting base and turn the
detector counterclockwise.

Mount the Base:
The detector can be mounted to any of the following surfaces:
• A single gang box
• A 3.5- or 4-inch octagonal box
• A 4-inch square box with a plaster ring
• A ceiling using drywall fasteners
Do Not Install the Detector:
• Where particles of combustion are normally present such as
in kitchens or garages (vehicle exhaust) or near furnaces, hot
water heaters, or gas space heaters.
• In very cold or very hot areas.
• In wet or excessively humid areas or next to bathrooms with
showers.
• In dusty, dirty, or insect-infested areas.
• Near fresh air inlets or returns or excessively drafty areas.
These can drive smoke away from the detector.
