Backup Battery Replacement; Repairs And Services - Universal Security Instruments USI-5204 Instructions Manual

Before using the alarm "silence" feature, identify the source of smoke and be certain that
safe conditions exist.
(UTHA) MAINTENANCE:
The smoke alarm is virtually maintenance free. However, under dusty conditions, a vacuum hose
may be used to clear the sensing chamber of dust.
Clean the smoke alarm at least once a month to remove dust, dirt or debris. Always turn off power
to smoke alarm before cleaning. Using a soft brush or wand attachment to a vacuum cleaner,
vacuum all sides and cover of smoke alarm. Be sure all the vents are free of debris.
If the smoke alarm is false alarming and cannot be restored to normal operation, the smoke alarm
should be replaced.

BACKUP BATTERY REPLACEMENT

Disconnect AC power before changing battery. Shock hazard exists if AC power is miswired.
The smoke alarm uses a 9 Volt battery. The battery should last for at least one year under normal
operating conditions. The smoke alarm has a low battery indicator, an audible "beep." It will operate
at 30-40 second intervals for a minimum of 7 days. When this indication occurs, replace the battery
with an Alkaline type (Eveready Energizer #522, Duracell #MN1604), Carbon-Zinc type (Gold Peak
(R)
#1604P, Eveready #216). Use the convenient QUICK DRAW pull-out batterydrawer for easy battery
replacement.

Pull the QUICK DRAW battery drawer open and remove the battery. While observing polarity,
push the replacement battery into the battery drawer until it is held securely in place. Carefully close
and latch the battery drawer.
