Operating/Installation Instructions
Install at least one (1) foot away from fluorescent lights,
electronic noise may cause nuisance alarms. Do not
place in direct sunlight and keep out of insect infested
areas. Extreme temperatures will effect the sensitivity
of the Smoke/CO Alarm. Do not install in areas where
the temperature is colder than 40 degrees Fahrenheit
(4.4 Celsius) or hotter than 100 degrees Fahrenheit
(37.8 Celsius). Place away from doors and windows
that open to the outside.
C. How to Install:
Remove mounting plate from the back of the unit by hold-
ing the rim of the mounting plate and twisting counter-
clockwise (left). Hold the mounting plate against the select-
ed installation location (wall or ceiling) and mark the cen-
ter of the holes with a pencil. To ensure aesthetic align-
ment of the alarm with the hallway, or wall, the "A" line on
the mounting plate must be parallel with the hallway when
ceiling mounting, or horizontal when wall mounting. Drill
a hole through the pencil marks and use the enclosed
screws and anchors to secure (use 3/16" drill bit for anchor
holes). Align the Smoke/CO Alarm with the mounting plate
and rotate clockwise (right) until the unit is aligned. Screw
and anchor accessories are supplied.
