Operating and Installation Instructions
dense, the alarm will silence immediately, the unit will
verbally announce “HUSH MODE ACTIVATED”, and the green
LED will flash every 2 seconds for approximately 10 minutes.
This indicates that the smoke alarm is in a temporarily desen-
sitized condition. Your Smoke/CO Alarm will automatically
reset after approximately 10 minutes. When the unit returns
to normal operation after being in HUSH® mode, it will ver-
bally announce “HUSH MODE CANCELLED”, and sound the
alarm if smoke is still present. The HUSH® feature can be
used repeatedly until the air has been cleared of the condition
causing the alarm. While the unit is in HUSH® mode, pushing
the test/reset button on the alarm will also end the HUSH®
period.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH®
CONTROL FEATURE AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM HUSH®
FEATURE, IDENTIFY THE SOURCE OF THE SMOKE AND BE
CERTAIN A SAFE CONDITION EXISTS.
Reset Feature
If the Smoke/CO Alarm is sounding a CO alarm, pressing the
test/reset button will initiate a test/reset. If the CO condition
that caused the alert continues, the alarm will reactivate.
Alarm/Peak Level Memory
If the green LED is blinking once every 16 seconds, the unit
has detected a hazardous condition. If the unit has detected
a CO level of 100 PPM or greater, pushing the Test/Reset
button will result in a voice message “Caution, carbon
monoxide previously detected”. Peak level also happens if
the unit detects smoke and then comes out of alarm.
However, there is no voice message if the unit is in peak level
due to smoke. When the Test/Reset button is pushed, the
unit will produce three rapid beeps. Pushing the test/reset
button resets the memory. It’s also reset when the power is
removed.
