Activate System, Alarm Set, Senor Trip Without Any Motion In Path?

The Honeywell IS215T is a passive infrared motion detector that is commonly used as part of a home security system. If there is a red button in the lower right-hand corner of the device, it is likely a tamper switch that is used to trigger an alarm if someone tries to remove or tamper with the device. Here's how to reset it:

First, make sure that your security system is disarmed and that the Honeywell IS215T is not detecting any motion.

Locate the red tamper switch in the lower right-hand corner of the device. This may be a small button or a switch that can be pushed or slid.

Press or slide the tamper switch back into its normal position. You may hear a click or feel a slight resistance when it snaps back into place.

Once the tamper switch has been reset, the device should resume normal operation. Check your security system's control panel to ensure that the Honeywell IS215T is communicating properly and that no alarms have been triggered.

Note that if you are unsure about how to reset the tamper switch on your Honeywell IS215T, you should consult the device's user manual or contact Honeywell's customer support for assistance. It's important to ensure that your security system is functioning properly and that all components are properly installed and maintained.
