2. Product Features and Specifications
Low Battery Warning
If the 9V battery is missing or battery power is low, the unit will chirp
every 15 seconds to indicate the battery must be replaced. If the battery
is depleted beyond the point of having the capacity to operate the unit,
it will chirp every 30 to 45 seconds and will NOT respond to the test
button being pressed if operating on battery power. THE BATTERY
MUST BE REPLACED IMMEDIATELY!
Low Battery HUSH ® CONTROL
When the battery needs to be replaced, the unit will produce a low
battery warning. The Low Battery HUSH feature allows you to press the
®
button on the alarm and disable the "chirp" for a random period of up
to 12 hours. This gives you a chance to replace the battery at a more
convenient time without sacrificing your safety by disconnecting the
alarm from power. During this Low Battery HUSH period, your alarm is
®
monitoring for CO.
IMPORTANT: Seven (7) years after the initial power up, this alarm
will "beep" every 30 seconds to indicate that it is time to replace
the alarm. Replace the alarm immediately! It will not detect CO in
this condition.
To help identify the date to replace the alarm, a label has been affixed to
the side of the alarm. Write the "replace by" date (seven years from
power up) in a permanent marker on this label.
