Installation
Battery Backup
Models i12040ACA and PE120CA with battery backup
will not function without a properly installed battery. They
are equipped with a battery lockout feature which
prevents the battery door from closing if a battery is not
installed correctly. See Maintenance section for additional
information concerning battery installation.
Testing
• To ensure proper operation of models i12040ACA and
PE120CA with battery backup, press 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.
• For all models: Confirm unit operation by pressing the
Test button again.
The smoke alarm is operating once AC power is applied, a
fresh battery is installed (only for battery backup models
i12040ACA and PE120CA) and testing is complete. When
the smoke alarm ionization sensor chamber senses products
of combustion, the horn will sound a loud (85db) alarm until
the sensing chamber is cleared of smoke particles.
Alarm Tamper Resist Feature
• To make the smoke alarm tamper-resistant, a locking
pin has been provided in the bag with the screws and
anchors. Using this pin will help deter children and
others from removing the alarm from the mounting
plate. To use the pin, insert it into the hole in the side
of the alarm after the alarm has been installed on the
mounting plate (Image 4D).
NOTE: The tamper-resistant pin will have to be removed in order to
change the battery (models i12040ACA and PE120CA). Use
long nose pliers to pull the pin out of the hole. It is now possible to
remove the alarm from the mounting plate.
