System Components
3.1 Description
The DMP 1912XR system is made up of an alarm panel with built in communicator, an enclosure, and a
16.5 VAC transformer. You can add up to eight Security Command keypads, an expansion interface
module, loop and output expanders, and initiating and indicating circuit modules. You can also connect
auxiliary devices to the panel's output relays to expand the basic system. Combined current requirements
of additional modules may require an auxiliary power supply. Refer to section 7.6 in this manual when
calculating power requirements.
3.2 Wiring diagram
The 1912XR system below shows some of the accessory modules you can connect for use in various
applications. A complete description of each module follows.
3.3 Lightning protection
Metal Oxide Varistors and Transient Voltage Suppressors help protect against voltage surges on input and
output circuits of the 1912XR. Additional surge protection is available by installing the DMP 370 or 370RJ
Lightning Suppressors.
