DMP XR150 / XR550 Series

The DMP XR150 and XR550 are Digital Monitoring Products' main commercial and high-end residential panels. They combine burglary, fire and access control on one board. Both use the same circuit board design, wiring and programming menus; the XR550 is the larger panel, with more zones, areas, keypads and door access points. Installation, programming and service are normally handled by a DMP dealer.

Shared hardware

• On-board zones: eight burglary zones (1–8, 1k or 2.2k ohm end-of-line) and two powered zones with reset for 2-wire smoke detectors (zones 9 and 10).
• Keypad bus (terminals 7–10): keypads, zone expanders, access control modules and up to 7 wireless keypads.
• LX-Bus (LX500 to LX900 headers): zone and relay expansion modules, zones 500–999.
• Wireless: an 1100XH receiver on the X-Bus header. DMP rates it for up to 100 wireless devices on an XR150 and 500 on an XR550 in residential use. The 1100T translator lets the panel use some Honeywell, 2GIG, Interlogix or DSC wireless sensors.
• Communication: built-in network (Ethernet) to DMP SCS-1R or SCS-VR receivers, an optional 263LTE cellular module, an optional 763 Wi-Fi module, and an optional 893A dual phone line module. The panel can also run as a local, unmonitored system.
• Outputs: 12 V DC bell output (1.5 A), two relay outputs (with Model 305 relays and a 431 harness), and four open-collector outputs.
• Power: 16.5 V AC 50 VA plug-in transformer (Model 327) or wire-in transformers. 12 V DC auxiliary power up to 1.5 A.

Catalog suffixes such as INT (international) and FC mark regional or application-specific versions of the same panels. Check DMP's documentation for the version on your board.

DMP keypads show plain-text messages rather than numeric codes. These are the ones service calls usually start with:

Summarized from DMP's Troubleshooting Guide (LT-1866).

Built-in feature codes

DMP panels use spelled-out numeric codes, entered at a keypad (on XR panels, press CMD after the code):

Programming and diagnostics need the panel to have been reset within the last 30 minutes. To reset, momentarily place a jumper across the two RESET pins.

The diagnostics menu

Diagnostics (2313) is the most useful tool on an XR panel:

• Test LX-Bus and LX-Bus Status find expansion modules that are not answering.
• Zone Finder and Zone State show which zone a device is on and its electrical state.
• X-Bus shows whether the wireless receiver is answering.
• Communication Status tests a single communication path (network, cellular).
• Cell Signal and Wi-Fi Signal show signal strength.

Battery trouble that will not clear

The panel load-tests the battery every 3 minutes for 5 seconds:

• Below 11.9 V, it reports battery trouble.
• The trouble clears once the battery reaches 12.6 V.
• Below 10.2 V, the panel disconnects the battery to protect it.

After fitting a new battery, entering and leaving programming restarts the test timer. If the trouble persists, check for about 13.8 V DC on the battery terminals with the battery disconnected and AC present. Much less points to a charging fault. DMP recommends replacing the battery every 3 to 5 years.

A dead keypad

Check, in order:

1. DC voltage at the keypad's harness
2. DC output on panel terminals 7 and 10 (about 13.8 V)
3. The wiring on terminals 7 and 10
4. AC input on terminals 1 and 2

Voltage drop between the panel and any device should be no more than 2 V. On long runs, add an auxiliary power supply.

Can't get into programming

Reset the panel with the RESET jumper, then enter 6653 and CMD within 30 minutes. If the keypad asks for a code, a programmer lockout code has been set. DMP says a lost lockout code means the panel must be sent back to DMP. If you took over an existing system, ask the previous dealer first.

• Keypads: DMP 7000 series Thinline/Aqualite keypads, 7873 and 7800 series graphic touchscreens, 8860 series 7-inch touchscreens (wired or Wi-Fi), and 9000 series wireless keypads. The Virtual Keypad app works through the panel's network or cellular connection.
• Zone expansion: 714 and 715 zone expanders.
• Access control: 734 and 734N door modules.
• Wireless: 1100XH receiver and 1100 series sensors; 1144 key fobs (zones 400–449); 1100T translator for compatible non-DMP wireless.
• Communication: 263LTE cellular, 763 Wi-Fi, 893A dual phone line.
• Automation: 738Z+ Z-Wave interface module.
• Power: 327 transformer; 364, 365 and 366 batteries.

• Ground the panel before applying power or connecting devices. DMP is emphatic about this for protection against electrostatic discharge.
• Do not use shielded or twisted-pair cable for the keypad bus or LX-Bus.
• Keypad bus zone numbering follows the device address: address 1 gives zones 11–14, address 2 gives 21–24, and so on up to address 16 (zones 161–164). LX-Bus zones run from 500 to 999.
• Programming can be done from a 32-character DMP keypad set to address 1, or with Dealer Admin or Remote Link.
• Default master code: XR panels ship with a unique four-digit default master code rather than one shared default. Change it, and set a programmer lockout code so only your company can program the panel.
• Do a battery calculation for the standby time your application needs (24, 60 or 72 hours). Large systems will need extra batteries or an auxiliary supply.
