To silence a smoke or CO alarm:
If the battery level is low, the LED indicator will flash yellow once every 60 seconds, and the buzzer will
beep every 60 seconds. To silence this alarm, press the Test/Silence button on the device. The device will
be temporarily mute for 10 hours.
When the battery is weak, the LED indicator will flash yellow three times with three beeps every 60
seconds. Press the Test/Silence button to stop the end-of-life signal for 22 hours. Note that this function
will only work within 30 days of the expiration date.
The device will remind you of any smoke and CO alarm you may have missed. If a smoke alarm was
triggered and then returned to standby mode after the smoke concentration decreased below the alarm
level, the LED indicator will flash red and yellow sequentially once every five seconds. If a CO alarm was
triggered and then returned to standby mode after the CO concentration decreased below the alarm
level, the LED indicator will flash red and yellow sequentially once every 30 seconds. To erase these alarm
reminders, press the Test/Silence button. Note that the smoke/CO alarm reminder will not work if the
device is battery-powered.
You can temporarily silence false alarms by pressing the Test/Silence button on any device.

To silence any interconnected smoke or CO alarm, press the Test/Silence button on the source alarm. To
locate the source alarm, press the Test/Silence button on any device; if all devices are silenced except for
one device, then the alarm still sounding is the initiating device. You can also locate it using the colored
LED indicator with a beeping pattern. The source alarm flashes red with three long beeps every four
seconds if a smoke alarm is triggered. If a CO alarm is triggered, it will flash red with four beeps every 5.8
seconds.
When you temporarily silence one device by pressing the Test/Silence button, other interconnected
devices are not silenced and will sound an alarm together if they detect smoke or CO.

Smoke Alarm
CO Alarm
The silence duration for a smoke alarm
is nine minutes. After that, if the smoke
concentration level reaches the alarm
level again, the device will alarm again.
The silence duration for a CO alarm is nine minutes, then it
will exit the silence mode. However, if after six minutes,
the CO concentration is still at the alarm level, the device
will alarm again. If the CO concentration is at a very
dangerous level higher than 300 ppm, the device cannot
be silenced.
