DMP XT30 / XT50 Series

The DMP XT30 and XT50 are Digital Monitoring Products' residential and small-business panels, the smaller siblings of the XR150 / XR550. Both use the same board layout, wiring and programming menus, so one page covers both. The XT50 adds capacity and built-in wireless zones. Installation and service go through a DMP dealer, and owners usually control the system with the Virtual Keypad app.

XT30 vs XT50

From DMP's XT30/XT50 programming and installation guides (LT-0981, LT-0980).

Shared hardware

• On-board zones: nine burglary zones (1–9, 1k or 2.2k ohm end-of-line) and one powered fire zone with reset (zone 10) for 2-wire smoke detectors.
• Keypad bus: up to eight supervised keypads, seven of which can be wireless. Keypad addresses 1–8 also carry expander zones 11–14, 21–24 … 81–84.
• Communication: built-in network (Ethernet) and phone dialer to DMP receivers; plug-in 263LTE cellular (Verizon or AT&T) or 263LTE-2 (both); optional 763 Wi-Fi module.
• Outputs: 12 V DC bell output (1.5 A) and four open-collector outputs (50 mA each; needs a Model 300 harness).
• Power: 16.5 V AC 40 VA plug-in transformer (Model 321); 12 V DC auxiliary power up to 500 mA. Replace the standby battery every 3 to 5 years.

The XT75 is DMP's newer panel in the XT line.

DMP keypads show plain-text messages:

See the XR150 / XR550 page for more DMP messages (4-WIRE BUS TRBL, WIRELESS TRBL, NON POLLED ADDR); they mean the same on XT panels.

Keypad problems

• Keypad dead, power LED off: connect AC and the battery, and check the keypad wiring on terminals 7–10.
• Keypad beeps but won't arm, disarm or open the menu: two keypads share an address, or more than eight devices are addressed. Give each keypad its own address.
• Missed keystrokes or a display that doesn't update: the wire run is too long or too thin. Use heavier wire, or add a power supply near the keypad.

Panel LEDs

• OVC (overcurrent) LED red: too much is drawn from auxiliary power, which is 500 mA maximum. Move devices to an auxiliary supply.
• Wireless TX LED off: the wireless house code isn't programmed (System Options).
• Wireless RX LED never flashes: transmitters aren't reaching the receiver. Check serial numbers and move the transmitter closer.
• TX and RX both on steady: the panel is held in reset or flash-load. Remove the RESET or LOAD jumper.

Battery trouble after a new battery

The panel tests the battery under load periodically. A new battery that isn't fully charged can show trouble until it charges. Let it charge, and check the connections before replacing anything else.

• Keypads: DMP Thinline and Aqualite alphanumeric keypads, graphic touchscreens, and 9000 series wireless keypads.
• Zone expansion: 711 single-zone, 714-8 and 714-16 expanders; 710 bus splitter/repeater for keypad runs up to 2,500 ft.
• Wireless: 1100 series receivers such as the 1100DH (XT30) and 1100 series transmitters; 1144 key fobs.
• Communication: 263LTE cellular, 763 Wi-Fi.

Entering the programmer

1. Put the jumper across both RESET pins for two seconds, then move it back to one pin.
2. At a keypad, enter 6653 (PROG). The keypad shows PROGRAMMER.
3. Press CMD to step through the programming sections, and choose STOP to save and exit.

Programming must start within 30 minutes of a reset, otherwise the keypad asks you to reset the panel. A dealer can set a lockout code. DMP warns that a lost lockout code means the panel goes back to DMP. You can also program with Dealer Admin.

Default user code

Current XT30/XT50 panels ship with a unique four-digit master code for first access to the user menu. Panels made before 2020 used 99. Initializing user codes in programming sets the code back to 99: on user 30 on the XT30, and on user 99 on the XT50.

Planning

• Keypad bus devices: no more than eight addresses.
• Check the auxiliary load against the 500 mA limit before adding keypads and expanders.
• The cellular module needs panel firmware version 212 or later (version 242 or later for the 263LTE-2).
