WARNING! 

z

 

The Hush Feature is for your convenience only and will not correct a CO problem. Always check your home for a 

potential problem after any alarm. Failure to do so can result in injury or death. 

z

 

NEVER remove the batteries from your CO Alarm to silence the horn. Use the hush feature. Removing the batteries 

removes your protection! See “If Your CO Alarm Sounds” for details on responding to an alarm. 

The Hush Feature is intended to temporarily silence your CO Alarm’s alarm horn while you correct the problem—it will not correct a 

CO problem. While the alarm is silenced it will continue to monitor the air for CO. 

When CO reaches alarm levels the alarm will sound— repeating horn pattern: 4 beeps, a pause, 4 beeps, etc. Press and hold the 

Test/Silence button until the horn is silent. The initial Silence cycle will last approximately 4 minutes. 

NOTE: 

After initial 4-minute Silence cycle, the CO Alarm re-evaluates present CO levels and responds accordingly. If CO levels 

remain potentially dangerous—or start rising higher—the horn will start sounding again. 

For the wireless devices in the same ID, when the devices are in 

Local alarm

 or 

Remote alarm status

 (refer to 

TABLE2

), 

Triggering the Hush function will lead all the devices to be in Hush Status.

 

 

LOCATE FEATURE 

When the devices alarming for detecting carbon monoxide, users can find the initial point through the Locate Feature :   

Find any one of the alarming device

Local Alarm or Remote Alarm

,    press the Test/Hush button and release it in 2 seconds. Then 

the Locate Feature will be triggered. After triggering Locate Feature, all the alarming devices will be stop sound, except the initial 

device which is detecting carbon monoxide signal keeps alarming until carbon monoxide signal goes off. 

REGULAR MAINTENANCE 

WARNING! 

Use only the replacement batteries listed below. The unit may not operate properly with other batteries. Never use 

rechargeable batteries since they may not provide a constant charge. 

This unit has been designed to be as maintenance-free as possible, but there are a few simple things you must do to keep it working 

properly: 

z

 

Test it every week using the Test button. 

z

 

Vacuum the CO Alarm cover once a month, using the soft brush attachment. Never use water, cleaners, or solvents, since 

these may damage the unit. Test the CO Alarm again after vacuuming. 

z

 

Replace the batteries when the CO Alarm “chirps” about every minute (the low battery warning). 

The low battery warning should last for 30 days, but you should replace the battery immediately to continue your protection. 

The unit requires one standard 9V battery. The following batteries are acceptable as replacements:   

Golden Power #6F22; New Leader #6F22; Gold Peak #6F22; Eveready #522, #1222.; Golden Power G6F22; Golden Power 

GL6F22A 

IMPORTANT! 

Actual battery service life depends on the Alarm and the environment in which it is installed. All the batteries specified above are 

acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life, 

you MUST replace the 

battery immediately once the unit starts “chirping” (the “low battery warning”).
