9F - Keypad
Remove the Keypad from its backplate. Pull the bottom of the Keypad slightly away from the wall and push
up. Open the battery cover and remove the batteries. Install four fresh Eveready Alkaline Energizer AA
batteries. Be sure to insert the
batteries in the proper orientation. Replace the Keypad on its mounting
plate, making sure it snaps into place.
9G - Smoke Detector
Remove the mounting plate from the detector by pushing the locking tab and turning the mounting plate
counter-clockwise.
Hold the unit with the battery compartment facing you, and the imprinted wording right-side up. Install the
first two batteries in the row nearest to you, with the + terminals facing left. Next, install the middle two
batteries with the + terminals facing to the right. Place your thumb over the centre of these four batteries
to keep them in place. Install the last two batteries, with their + terminals facing to the left, by snapping
them past the nylon retainer.
The smoke detector is designed to use Eveready Energizer Alkaline Batteries. Do not use
other brands of batteries with the smoke detector. Using brands other than the Eveready
Energizer will void UL and ULC approvals, and may affect the system's operation.
9H - After Installing New Batteries
Refer to Section 5 of this manual for information on displaying Sensor Faults and Tamper Faults on the
Keypad screen. A Tamper Fault should be displayed for each Sensor that was removed from its backplate
when its batteries were changed; a Sensor Fault may also be displayed for these Sensors.
Be sure to perform a walk test of your system after new batteries are installed to ensure
that all Sensors are working properly.
Replacing the batteries and performing the walk test will also clear any Low Battery, Sensor Fault, and
Tamper Fault indications from the Keypad.
