4. Taking care to avoid any electrical wiring in the ceiling or wall, drill a hole
through the centres of the marked locations. Push the plastic screw anchors
provided into the drilled holes. Screw in firmly.
5. Close the cover until it snaps together with the base.
b. Placing the battery
The battery is easily removed from the holder by holding back one of the plastic
clips while lifting the battery with the other hand.
1. Snap Battery Connectors to Battery. They fit together only one way.
2. Gently push battery into battery holder.
3. With a pencil, write the date of battery installation on the inside of the
cover to remind you when to replace the battery.
4. To close the cover match up snap-in hinges and gently press together
until base and cover snap together. Test the installed Smoke Detector –
see 6b Manually testing your Smoke Detector.
NOTE: You may hear a loud chirp when attaching the Battery Connectors to the
Battery.
c. Battery
Missing indicator
This Smoke detector fitted with a warning flag which pops up when the battery is
removed. This prevents the cover from closing when there is no battery in the unit.
When the battery is being installed or changed, this flag must be held down while
gently pushing the Battery into the Battery Holder.
6. LOOKING AFTER YOUR SMOKE DETECTOR
a. Automatic
Self-Test
The smoke chamber automatically tests itself every 40 seconds. If the chamber is
degraded it will beep without the LED flashing at the same time. If this happens
clean the unit. If the beeping persists and the beep does not coincide with an LED
flash, return the unit to service.
b. Manually testing your Smoke Detector
It is recommended that you test your Smoke Detector at least once a week to be
sure the unit is working. It will also help you and your family to become familiar with
the sound of the alarm.
When you press the Test Button it simulates the effect of smoke during a real fire.
So, there is no need to test the Alarm with smoke.
Press and hold the Test button until the Alarm sounds (it may take up to 10
seconds). The alarm will stop sounding shortly after the Button is released. If the
alarm fails to sound, follow this checklist.
