Battery Life Expectancy:
Replace the battery once a year or immediately when the low battery
indicator starts to blink and the horn begins to chirp.
Battery Installation and Replacement:
To replace the battery:
1. Remove the detector from its mounting base by twisting the detec-
tor counterclockwise. Remove the battery and dispose of it
properly.
2. To ensure proper power-down sequence, wait a minimum of 20
seconds before installing new battery.
3. Install a new approved 3-volt Lithium battery in the battery com-
partment. Follow the polarity diagram inside the compartment.
4. Reinstall the smoke detector onto the mounting base by turning
the detector clockwise.
5. The green LED should blink about once every 10 seconds to indicate
normal operation. If the battery is not installed correctly, the smoke
detector will not operate and the battery may be damaged. If the
detector does not appear to be sending a signal during any of the
tests, check for correct battery installation and for a fully charged
battery.
6. Test Smoke detector operation with Signature Series Receiver to
verify proper operation.
