XR6/XR10/XR20 Installation Guide
System Components
3.1 Description
The DMP XR6/XR10/XR20 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 XR20 and
four points to the XR6.
3.2 Wiring diagram
The XR6/XR10/XR20 system wiring diagram in Figure 1 shows some of the accessory devices you can connect
for use in various applications. A complete description of each module follows. Zone expanders can be added to
the XR6 or XR20.
3.3 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.
3.4 Command Processor Accessories
You can connect any combination of up to four Model 670, 770, and 771 vacuum fluorescent, 690, 790, 791, and
793 LCD, or 692 LED Security Command Keypads to the 4-wire keypad data bus provided by the panel on
terminals 7, 8, 9, and 10. Also, you can connect Model 714, 715, 714-8, 714-16, 715-8, 715-16 zone expanders
to the XR20 or XR6 4-wire keypad bus. (Note: The XR10 does not support zone expansion on the keypad bus.)
