Description
The DMP XR6A/XR10A/XR20A system is made up of an alarm panel with built in communicator, an enclosure, a
16.5 VAC transformer, and a 12 VDC 7.0 Ah battery. You can add up to four Security Command keypads to the
system and can also connect auxiliary devices to the panel's open collector outputs to expand the basic system.
Combined current requirements of additional modules may require an auxiliary power supply. Refer to section 6.6 in
this guide when calculating power requirements. In addition, up to 16 points of zone expansion can be added to the
XR20A and four points to the XR6A.

Lightning protection
Metal Oxide Varistors and Transient Voltage Suppressors help protect against voltage surges on input and output
circuits. A transorb is provided for the Smoke Detector Output Circuit (Terminal 11). This transient protection
provides additional resistance to electrical surges such as lighting. Additional surge protection is available by
installing the DMP 370 or 370RJ Lightning Suppressors.
