LED Indicator Operation

Red LED
Red LED will flash in conjunction with the alarm beep.
Therefore, the red LED will flash during a smoke alarm, a CO
alarm, a low battery mode chirp and a unit error mode chirp.
Green LED
The green LED will flash as described below under the following
conditions:
– Standby Condition (powered by AC and battery backup):
The LED will be constantly on, but will flicker every 30
seconds when a CO reading is taken.
– Standby Condition (for model KN-COSM-IB only –
powered by only battery backup):
The LED will flash every 5 seconds.
– Alarm Memory Condition: The LED will flash every
second signifying that the alarm sensed a smoke or CO
hazard. It will continue to flash every second until the
test/reset button is pressed, thus resetting the alarm.
– HUSH MODE Condition: The LED will flash every 2
seconds while the alarm is in HUSH mode.

Tamper Resist Feature

To make your smoke/CO alarm tamper resistant, a tamper resist
feature has been provided. Activate the tamper resist feature by
breaking off the four posts in the square holes in the trim ring
(see figure 5A). When the posts are broken off, the tamper
resist tab on the base is allowed to engage the mounting brack-
et. Rotate the alarm onto the mounting bracket until you hear
the tamper resist tab snap into place, locking the alarm on the
mounting bracket. Using the tamper resist feature will help
deter children and others from removing the alarm from brack-
et. NOTE: To remove the alarm when the tamper resist tab is
engaged, press down on the tamper resist tab, and rotate the
alarm off of the bracket (see figure 5B).
