THINGS TO KNOW
DMP FEATURE CODES
All XR Series panels use a number to access certain features� Some of these features include the programmer menu,
diagnostic menu, and the walk-test function�
Most of these codes have a word-equivalent that can be spelled out using the keys on the keypad:
DMP FEATURE CODE MENU ITEMS
DMP FEATURE CODE SPELLING
Programmer Menu 6653 PROG
Diagnostics Menu 2313 DIAG
Walk Test Menu 8144 WALK
Keypad Options 3577 INST
Communication Test Menu 984
COMMON VOLTAGES
These operating voltages are the same across the entire XT30/50 and XR150/550 product-line:
1
AC input (terminals 1 and 2) – 17�3 VAC (We include 16�5 VAC Power Supplies�)
2
Charging circuit output (terminals 3 and 4) – 13�9 VDC
3
Auxiliary power output (terminals 7 and 10) – 13�8 VDC
4
Panel data receive output YELLOW (terminals 8 and 10) – approx� 4�5 VDC
5
Panel data transmit output GREEN (terminals 9 and 10) – approx� – 3�5 VDC
OPERATIONAL PARAMETERS FOR XR PANEL ZONES 1 - 8 & XT PANEL ZONES 1 - 9
ZONE CONDITION RESISTANCE ON ZONE VOLTAGE ON + TERMINAL
OPEN More than 1300 Ohms Above 2�0 VDC
NORMAL 600 - 1300 Ohms 1�2 - 2�0 VDC
SHORT Less than 600 Ohms Below 1�2 VDC
The following chart shows the operational parameters for XR Panel zones 1 - 8 and XT Panel zones 1 - 9 when 2�2K resistors
are enabled on v193 or higher firmware�
