Low Battery Condition: The red LED flash will be accompanied by an audible chirp. Replace the battery when this condition occurs.

Alarm Memory: This smoke alarm is equipped with an alarm memory which provides a visual indication when an alarm has been activated. A steady on red LED indicates the memory condition. The memory will remain activated until it is reset by pushing the test button.

In an interconnected installation only the memory of the originating alarm will be activated.

SMOKE SENSING CHAMBER OPERATION: This alarm will “chirp” if any of the components in the smoke sensing chamber fail. This chirp will occur between the flashes of the red LED indicator light. (If the chirp occurs at the same time as the red LED flash, see section 6 for low battery information).

WHEN UNITS ARE INTERCONNECTED, only the red LED of the alarm “which senses the smoke” or “is being tested” (the originating unit) will flash rapidly. All other units in the interconnect system will sound an alarm but their red LED’s will NOT flash rapidly.

TESTING: Test by pushing the test button on the cover and hold it down for a minimum of 5 seconds. This will sound the alarm if the electronic circuitry and horn and battery are working. In an interconnected installation all interconnected alarms should sound when the test button on any one of the interconnected alarm is pressed. If no alarm sounds, the unit has defective batteries or other failure. DO NOT use an open flame to test your alarm, you could damage the alarm or ignite combustible materials and start a structure fire.

TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound coming from your alarm may indicate a defective alarm, and it should be returned for service (see section 12).

NOTE: WEEKLY TESTING IS REQUIRED.

5. NUISANCE ALARMS

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
