5. HUSH CONTROL FEATURE
The Hush button is extremely useful in a kitchen area or other areas prone to nuisance
alarms. The Hush feature has the capability of temporarily desensitizing the smoke
alarm circuit for about 9 minutes. This feature should only be used when a known
alarm condition, such as smoke from cooking, activates the alarm. If the alarm does
sound, check for fires first. If a fire is discovered, get out and call the fire department.
If no fire is present, check to see if one of the reasons listed in Locations to Avoid may
have caused the alarm. The smoke alarm is desensitized by pushing the Hush button
on the smoke alarm cover. If the smoke is not too dense, the alarm will silence
immediately for approximately 9 minutes. The LED will flash every 10 seconds during
the 9 minute hush. This indicates that the alarm is in a temporarily desensitized
condition. The smoke alarm will automatically reset after approximately 9 minutes.
If after this period particles of combustion are still present, the alarm will sound again.
The Hush feature can be used repeatedly until the air has been cleared of the
condition causing the alarm. Pushing the Test button on the alarm will end the Hush
period.
IF THERE IS ANY QUESTION AS TO THE CAUSE OF AN ALARM, IT SHOULD BE
ASSUMED THAT THE ALARM IS DUE TO AN ACTUAL FIRE AND THE DWELLING
SHOULD BE EVACUATED IMMEDIATELY.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH CONTROL FEATURE AND
SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM SMART HUSH FEATURE. IDENTIFY
THE SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
6.MAINTENANCE
BATTERY REPLACEMENT
If tamper resist has been used, refer to Figure 6 in Section 3 for alarm removal
instructions.
WARNING:
Alarm will not attach to mounting bracket unless battery is installed.
Removal of battery will render the unit inoperative.
To replace the battery, remove the alarm from the mounting plate by rotating the
alarm in the direction of the “OFF” arrow on the cover (see Section 3, Figure 4).
The Smoke Alarm is powered by a 9V alkaline battery. A fresh battery should last for
a minimum of 5 years under normal operating conditions. This alarm has a low
battery monitor circuit that will cause the alarm to “chirp” approximately every 30-
40 seconds for a minimum of thirty (30) days when the battery gets low. Replace the
battery when this condition occurs. Be sure to push the test button to confirm proper
operation after replacing the battery. When the alarm is in low battery condition,
pressing the hush button will silence it for 8 hours.
