Reset and Tamper Headers
23.1 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 XR2500F microprocessor. To reset the panel when first 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.

23.2 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.
