10. Hush Control Feature
The Hush feature 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 button on the smoke alarm cover. The alarm will silence immediately
for approximately 9 minutes and the red LED will blink every 2 seconds. 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.
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.
CAUTION: Before using the alarm smart hush feature. Identify the source of the smoke and be
certain a safe condition exists.
