Burglary Alarm Systems for Homes and Businesses

We install and service DMP alarm systems across the Hudson Valley, from a single-family home to a multi-building commercial site. Every system is supervised by a UL Listed monitoring center 24/7, with cellular backup so alarm signals get through even if phone and internet lines are cut.

Which panel you need comes down to how big the building is and whether you want burglary, fire, and door access running on one system. We size it during a free walk-through, and most existing wiring and devices can be reused.

DMP XTLtouch wireless alarm panel

XT30 and XT50: homes and small business

The XT Series is the workhorse for houses, apartments, and small commercial suites. It runs All/Perimeter, Home/Sleep/Away, or up to six independent areas, so one building can be split between tenants or departments without a second panel.

  • XT30 expands to 42 zones, XT50 expands to 58 zones
  • Up to six areas, with 16-character zone, user, and area names
  • 30 four-digit user codes on the XT30, 99 on the XT50
  • Network, dialer, LTE cellular, or Wi-Fi, plus a backup path
  • Virtual Keypad app for Apple and Android
  • Open/Close schedules with Closing Check and Zone Activity Hours
  • 100-event memory on the XT30, 200 events on the XT50
  • Supports up to 140 Z-Wave devices for lights, locks, and thermostats

DMP XR150 commercial control panel

XR150 and XR550: commercial, on one panel

The XR Series is a combined burglary, fire, and access control panel. That matters on a commercial job, because it means one panel, one monitoring account, and one app instead of three systems that do not talk to each other. The XR150FC and XR550FC add a built-in Fire Command Center for buildings that need a listed fire panel.

  • Combined burglary, fire, and access control with battery backup
  • Eight on-board burglary zones plus two powered zones for 2-wire smoke
  • LX-Bus expansion to hundreds of zones on the XR550
  • Up to 16 keypads and expansion modules on the keypad bus
  • Eight doors on the XR150, 32 on the XR550, expandable to 96
  • Network, dialer, LTE cellular, Wi-Fi, or Contact ID reporting
  • 128-bit and 256-bit encrypted reporting on XR550E panels
  • Two SPDT relay outputs and four programmable open collector outputs

Access control on the same system

Adding doors to a DMP panel does not mean adding a second system. A 734 Series module connects readers straight to the panel, so a badge can unlock a door and disarm the area in one action, and every door event lands in the same history as the alarm events.

When someone leaves, you delete their credential in the app. No re-keying and no chasing keys, and you can pull a report of who opened which door and when.

  • OSDP and Wiegand readers, 26 to 40 bit, up to eight card formats
  • Prox, smartcard, key fob, biometric, and mobile wallet credentials
  • Built-in 10-amp Form C door strike relay, 1 to 250 second strike time
  • 734N over the network, 734N-POE on one PoE cable, 1134 wireless
  • Request-to-Exit input for a motion detector or push-to-exit switch
  • AES encryption on the 734N and 734N-POE modules
  • Entry and exit reports by user, door, and area
  • Access granted by schedule, authority level, and profile
DMP AX-20 multi-technology access control reader

Door hardware we install

Readers and modules get matched to the door. A network module suits a building with structured cabling already in place; a wireless module saves trenching out to a gate or a detached warehouse.

DMP 734N network access control module

The 734N connects a door to the panel over the existing IP network, and the 734N-POE runs on a single Power over Ethernet cable. Four programmable zones per module cover the door contact, request-to-exit, and auxiliary inputs.

DMP 7800 Series touchscreen keypad

The 7800 Series touchscreen keypad arms, disarms, and annunciates in plain English. A keypad with a built-in proximity reader can double as the reader on a main entry door.
