A tamper error occurs when the panel is reading that the sensor's cover is not attached properly. To address the tamper error on your DSC PG9914 PIR motion detector, follow the instructions below.
1. To open the cover, remove the locking screw from the bottom, then press the tab at the bottom of the sensor to remove the cover.
2. Ensure the battery is correctly installed and that there are no loose springs or obstructions preventing the cover from fitting snugly with the motion sensor.
3. Close the device cover, ensuring the cover snaps completely into place and conforms with the sensor.
