Installation
Test & Battery Backup
• Alarm will not function without a properly installed battery. It is equipped with a
battery lockout feature which prevents the battery door from closing if a battery is
not installed correctly (See Figure 5).
• To ensure proper operation, depress the Test button for at least 5 seconds, or until the
alarm sounds (without the AC power connected). All interconnected, battery backed-
up alarms, should respond.
• Caution: Due to the loudness (85 decibels) of the alarm, always stand an arms-length
away from the unit when testing.
• Turn on the AC power. The green LED power indicator should be lit when the alarm is
operating from AC power.
• Confirm unit operation by pressing the Test button again.
• The smoke alarm is operating once AC power is applied, a fresh battery is installed
and testing is complete. When the smoke alarm senses products of combustion, the
horn will sound a loud (85db) alarm until the sensing chamber is cleared of smoke
particles.
