Reset and Tamper Headers
19.1 J16 Reset Header
The reset header is located just above the terminal strip on the right side of the circuit board and is used to reset
the XR500/XR500N microprocessor. To reset the panel when
Þ
rst installing the system, install the reset jumper
before applying power to the panel. After connecting the AC and battery, remove the reset jumper.
To reset the panel while the system is operational, for example, prior to reprogramming, install the reset jumper
without powering down the system. Remove the reset jumper after one or two seconds.
After resetting the panel, begin programming within 30 minutes. If you wait longer than 30 minutes, you must reset
the panel again.

19.2 J4 Tamper Header
The J4 header is for use with the optional DMP 306 Tamper Harness. The harness connects to one or more tamper
switches mounted inside the panel enclosure to supervise against unauthorized enclosure opening or removal. Refer
to the wiring diagram on the enclosure door for correct tamper switch wiring.
How the Tamper Works
If the enclosure is opened or removed while one or more of the system areas are armed, a panel tamper alarm is
indicated. If all areas are disarmed, a panel tamper trouble is indicated.
