Universal Electronics CD-9775 manual Page

STANDBY (NON-ALARM) CONDITION: Whenever battery power is present, the Green LED is off and flashes on approximately every 40 seconds and the Red LED is off.

(ALARM) CONDITION: For BOTH the SMOKE and CO alarm conditions, the Red LED flashes on and the unit emits a loud, pulsating alarm (refer to the OPERATION section to differentiate between the SMOKE and CO alarm patterns).

RESETTING YOUR ALARM: Reset your alarm by momentarily pushing the "TEST/SILENCE" button.

NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to your home. The built-in test switch accurately tests the unit's operation as required by Underwriters Laboratories Inc. (UL).

If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it only as directed. Use of non-UL Listed products or improper use of UL Listed products may affect the smoke alarm's sensitivity.

Before using the alarm "test/silence" feature, identify the source of smoke or CO and be certain that safe conditions exist.

FALSE ALARMS "TEST/SILENCE" CONTROL: Units with the "silence" feature have the capability of temporarily reducing the sensitivity of the smoke alarm circuit for approximately 3-9 minutes. This feature is to be used only when a known alarm condition such as smoke from cooking activates the smoke alarm. The smoke alarm "silence" feature is activated by pushing the Test/Silence button on the smoke alarm cover for at least three seconds. The smoke alarm will automatically reduce sensitivity and the Red LED will flash on every 6 seconds and "beep" sounder approximately every 36 seconds for approximately 3-9 minutes to indicate the alarm is in the temporary silent condition. The smoke alarm will gradually regain normal sensitivity and sound the alarm if particles of combustion are still present. The "silence" feature may be used repeatedly until the air has cleared.

MAINTENANCE: This combination alarm is virtually maintenance free. However, under dusty conditions, a vacuum hose may be used to clear the sensing chamber of dust.

Clean the alarm at least once a month to remove dust, dirt or debris. Using a soft brush or wand attachment to a vacuum cleaner, vacuum all sides and cover of alarm. Be sure all the vents are free of debris.

The outside of the alarm can be wiped with a damp cloth. Do not use any household cleaning agents, ammonia-based cleaners, paints, varnishes or any other chemical on or near your alarm.

AFTER CLEANING, REINSTALL YOUR ALARM. TEST YOUR ALARM BY USING THE TEST BUTTON.

SERVICE CONDITION: Periodically, the alarm's circuitry is tested. If an error is detected, the alarm will sound a double "beep" and the Yellow LED will flash on twice approximately every 40 seconds. If this occurs, reset your alarm by momentarily pushing the "TEST/SILENCE" button.

If the smoke/CO alarm is false alarming or indicating service and cannot be restored to normal operation, the alarm should be replaced.
