- PLACE YOUR SYSTEM ON TEST
Before changing the battery, ensure the system is disarmed and go to Guardian's Customer Care Website. You may also contact our Customer Service Department at 1-888-895-4805 to have your system placed on test. This ensures Guardian doesn't accidentally notify the authorities.
- LOCATE THE HEAT DETECTOR WITH THE LOW BATTERY(IES).
Gently twist the heat detector in a counter-clockwise motion, approximately a quarter turn, to release the cover.
Once the cover is released, unhinge the cover and access the battery(ies).
Please Note: The keypad may emit a beeping tone to indicate that the cover has been removed.
- INSTALL THE NEW BATTERY(IES)
Remove the existing battery(ies). If two batteries are inside the heat detector, both batteries must be replaced at the same time. After the old battery(ies) have been removed for 30 seconds, install the replacement battery(ies), paying attention to polarity. (Ensure that the positive (+) end of the battery matches the positive (+) symbol inside the heat detector.)
Replace the heat detector cover by locating the connection ridge. This ridge should line up with the groove or ridge on the outside ring of the device. Turn the cover in a clockwise motion until secured.
- TEST THE HEAT DETECTOR.
After replacing the battery(ies), Guardian recommends testing the heat detector to ensure it is working properly. Press the Test button for approximately 30 seconds, until the heat detector beeps. This will ensure that the heat detector is working properly. If the heat detector does not have a Test button, locate the small pin-hole and insert a thin piece of metal with a point at one end (e.g., a pin or part of a paper clip). Hold in until the sensor beeps.
Confirm the test signal was received before having your system removed from Test Mode.
Test your system to make sure everything is working properly and return to Customer Care Website or contact Guardian's Customer Service Department at 1-888-895-4805 to have your system removed from Test Mode.
