Operating Instructions
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 fol- lowing conditions:
–Standby Condition (powered by AC and battery back- up): The LED will be constantly on, but will flicker every 30 seconds when a CO reading is taken.
–Standby Condition (powered by only battery backup): The LED will flash every 30 seconds.
–Alarm Condition: The LED will flash every second sig- nifying that the alarm sensed a smoke or CO hazard. If the green LED is not flashing every second while sounding an alarm, then the alarm is acting as a remote sounder and an alarm in another area is ini- tializing the warning.
–HUSH MODE Condition: The LED will flash every 2 seconds while the alarm is in HUSH mode.
–Alarm Memory: The LED blinks once every 16 seconds to indicate a hazardous condition was previously detected.
Tamper Resist Features
To make your smoke/CO alarm tamper resistant, two tamp- er resist features have been provided. The first is used to discourage removal of the alarm while the second is for the battery. To activate the mounting bracket tamper resist fea- ture break 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 bracket. 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 bracket.
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).
