2. Product Features and Specifications
Low Battery Warning
If the battery is missing or battery power is low, the unit will chirp every
60 seconds to indicate the batteries must be replaced.
THE BATTERIES MUST BE REPLACED IMMEDIATELY!
Low Battery HUSH ® CONTROL
When the batteries need to be replaced, the unit will produce a low bat-
tery 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 by disconnecting the alarm from power. During this
Low Battery HUSH® period, your alarm is monitoring for CO.
Tamper-Resist Feature
The tamper resist is an optional feature and DOES NOT need to be
activated for the CO alarm to function properly. The Tamper Resist
feature is a constant 85dB alert to indicate the unit has been
unplugged or has come loose from the outlet. THIS FEATURE IS INI-
TIALLY DISABLED FROM THE FACTORY AND MUST BE ACTIVATED IF
FEATURE IS DESIRED. To activate the tamper resist feature: Move the
tamper resist activate slide to the "ON" position. Once enabled, there
is a two minute delay when power is supplied to give you time to
plug in the unit after activating the batteries. This feature is automati-
cally disabled once the battery voltage has reached a level to cause a
low battery warning chirp. Pressing the Test/Reset button will defeat
the 85dB tamper alarm for two minutes to allow time for the batter-
ies to be changed without the alarm sounding. To deactivate the
tamper resist feature, press in the tamper resist activation switch and
move the activate slide to the "OFF" position.
