• 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. Air con-
ditioners, heaters, fans, and fresh air intakes and returns can drive
smoke away from the detector.
Note: This unit is UL listed as containing a supplemental sounder and should
not be used as a primary sounder for evacuation.

the end of the feed wire, inserting it into the proper base terminal, and tight-
ening the screw to secure the wire in place. Do not put wires more than 2
gauge apart under the same clamping plate.
Remove power from alarm control unit or initiating device circuits before installing detectors.
1. Remove detector from packaging and separate the base from the detector head.
2. Wire the detector base screw terminals.
3. Screw the base of the detector onto an electrical box, or to the surface of
the wall or ceiling using the hardware included in the packaging.
4. Attach the detector head to the base by applying light pressure and rotat-
ing clockwise. The detector will lock in place when properly aligned.
5. After all detectors have been installed, apply power to the alarm control
unit. Refer to Table 3 for time to LED stabilization. Once stabilized, the
green LED will blink once every 5 seconds.
6. Test each detector as described in the Testing section.
7. Notify the proper authority that the system is in operation.
NFPA 72 recommends the installation of detectors only after completing construction or
any other dust producing activity

TESTING
The detector must be tested after installation. The detector has two discrete
test switches, one for smoke testing and one for CO testing. The detector may
also be functionally tested using canned smoke and canned CO.
NOTE: Before testing, notify the proper authorities to avoid any nuisance alarms.
Ensure the proper wiring and power is applied to the detector. After power
up, allow approximately 5 minutes for the detector to stabilize before testing.
