The Differences Between the Hush and Smart Hush Features

HUSH Feature

The "HUSH" feature allows you to temporarily desensitize the smoke alarm circuit for approximately 7 minutes. This feature should only be used when a known alarm condition, such as smoke from cooking, activates the alarm.

To activate the HUSH feature, simply push the "HUSH" button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and "chirp" every 30-40 seconds for about 7 minutes, indicating that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 7 minutes and sound the alarm again if particles of combustion are still present.

You can use the HUSH feature repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test/Reset button on the alarm will end the hush period.

Smart HUSH Feature

The "Smart HUSH" feature also allows you to temporarily desensitize the alarm circuit, but for up to 8 minutes. This feature should only be used when a known alarm condition, such as smoke from cooking, activates the alarm.

The Smart HUSH feature cannot be activated unless the smoke alarm is sounding in the originating alarm mode. To activate it, push the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. The red LED will illuminate for 1.5 seconds every 8 seconds while in hush mode, indicating that the alarm is in a temporarily desensitized condition.

he smoke alarm will automatically reset after approximately 8 minutes and sound the alarm again if particles of combustion are still present. You can use the Smart HUSH feature repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test/Hush button on the alarm will end the hush period.

Note: Dense smoke will override the HUSH control feature and sound a continuous alarm.

Caution: Before using the smoke alarm's HUSH feature, identify the source of the smoke and be certain a safe condition exists.
