Hush® Control Feature
Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will not normally set off the alarm, unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm if the alarm is located close to the cooking area. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood that vents to the outside
The Hush® feature has the capability of temporarily desensitizing the smoke alarm circuit for about 7 minutes. This feature is to be used only 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 and “chirp” every
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.
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.

LED Indicators
This alarm is equipped with red and green LED indicators, each with two modes of operation.
Red LED - Flashing eve ry
Red LED - Flashing Rapidly: When the smoke alarm senses particles of combustion and goes into alarm (constant pulsating sound), the red LED will flash rapidly (one flash per second). The rapid flashing LED and pulsating alarm will continue until the air is cleared. When interconnected, only the red LED’s of the alarms that are sensing smoke or are being tested will flash rapidly (originating alarms). All other units in the interconnect system will sound an alarm, but their red LED’s will NOT flash rapidly.
G reen LED - Constantly On: Indicates that the unit is receiving 120 V AC power.
G reen LED - Flashing: This unit features an “alarm memory” to indicate itself as an originating alarm (that sounded and triggered others in an interconnect system). Once the unit returns to silence after the occurrence of an alarm, a flashing green LED marks the unit as an originating alarm (Image 8). The flashing green LED remains until it is reset by pushing the Test button.
