CHAPTER 4:
Testing and Maintenance
WEEKLY TESTING
WARNING!
DO NOT stand close to the alarm when the
horn is sounding. Exposure at close range
may be harmful to your hearing. When
testing, step away when horn starts
sounding.
Push and hold the Test/Silence button on the
cover until you hear a “chirp.” The “chirp”
marks the start of the self-test sequence.
• First, the BATTERY (green) and
SERVICE (yellow) lights will flash briefly—
this is normal.
• Next, the alarm horn will sound: 4 beeps,
a pause, then 4 beeps. The ALARM (red)
light will flash quickly.
The alarm sequence should last 5-6 seconds.
If it does not alarm, make sure the battery is
correctly installed, and test it again. If the unit
still does not alarm, replace it immediately.
NOTE:
When you press and hold the Test/Silence
button, if the battery is low or weak, the
BATTERY light will flash YELLOW. Even if the
horn sounds, you should replace a low or weak
battery immediately for optimum performance.
If the alarm does not test properly:
1. Make sure the battery is installed correctly.
2. Be sure the alarm is clean and dust-free.
3. Install a fresh 9V alkaline or lithium battery*
and test the alarm again.
If the CO Alarm is not working properly, refer to
the “Limited Warranty” at the end of this
manual.
CAUTION!
If there is still a problem, do not try to fix the
alarm yourself—this will void your warranty!
Install a new CO Alarm immediately. CO
Alarms under warranty can be returned to
BRK Brands, Inc. for replacement (see
Limited Warranty for details).
WARNING!
The Test/Silence button is the only proper
way to test the CO Alarm. NEVER use
vehicle exhaust! Exhaust may cause
permanent damage and voids your warranty.
*For a list of acceptable replacement batteries,
see “Regular Maintenance.”
