1912XR Installation Guide
Introduction
2.1 Description
The DMP 1912XR Command Processor is a powerful 12 VDC, combined burglary and fire communicator
panel with battery backup. The 1912XR provides four on-board burglary loops and one on-board 12 VDC
Class B powered fire loop. The fire loop has a reset capability to provide for 2-wire smoke detectors, relays,
or other latching devices. The 1912XR can communicate to one or two DMP SCS-1 Receivers using digital
dialer, Contact ID, multiplex, or a combined dialer/multiplex format.
2.2 Expansion loops
Up to 132 additional loops are available on the 1912XR by using the loop expansion capability of DMP
Security Command keypads and loop expander modules. The panel's keypad data bus supports up to eight
device addresses with each device supporting up to four programmable expansion loops.
Up to 100 loops are available on the LX-Bus™ of a DMP 862N, 862P, 872, or 881 Interface Card using
combinations of the following:
• 711 Single Point Loop Expander Module (up to 100)
• 714 or 715 Loop Expander Modules (up to 25)
• 6155LX PIRs or 5845LX Glassbreak Detectors (up to 100)
