WARNING! 

z

 

This CO Alarm is designed for use inside a single-family home or apartment. It is not meant to be used in common 

lobbies, hallways, or basements of multi-family buildings unless working CO Alarms are also installed in each family 

living unit. CO Alarms in common areas may not be heard from inside individual family living units. 

z

 

This CO Alarm alone is not a suitable substitute for complete detection systems in places which house many people, 

like hotels or dormitories, unless a CO Alarm is also placed in each unit. 

z

 

DO NOT use this CO Alarm in warehouses, industrial or commercial buildings, special-purpose non-residential 

buildings, or airplanes. This CO Alarm is specifically designed for residential use, and may not provide adequate 

protection in non-residential applications. 

HOW TO INSTALL THIS ALARM 

This CO Alarm is designed to be mounted on any standard wiring junction box up to a 4-inch (10 cm) size, on either the ceiling or 

wall (if allowed by local codes). Read “Where to Install This Alarm” and “Where This Alarm Should Not Be Installed” before you 

begin installation.   

WARNING! 

Make sure the Alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same 

circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. 

Excessively noisy power may cause damage to your Alarm.

From back of alarm, remove the mounting plate by turning it counterclockwise. 

(To later engage tamper-resist feature, twist out and set aside one of the pins 

molded into plate. Both pins are exactly the same.) 

2.

 

Secure plate to ceiling or wall with mounting screws.

Position alarm to mounting plate and turn clockwise to lock into place. To 

engage tamper-resist feature, insert pin into notch on edge of alarm after alarm 

is properly positioned in base.
