Introduction
System Components
3.1Description
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.
3.2Wiring diagram
The XR6A/XR10A/XR20A 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 XR6A or XR20A.
3.3Lightning 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.
3.4Command 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
