System Components

3.1 Description

The DMP 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 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 the Standby Battery Power Calculation section

in this guide when calculating power requirements. In addition, up to 32 points of zone expansion can be added to

the XR40, 16 points to the XR20, and 16 points to the XRSuper6.

3.2 Wiring diagram

The 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 XRSuper6,

XR20, and XR40. Wireless interface can also be added to the XRSuper6, XR20, and XR40.

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 (up to four on XRSuper6 and XR20, and up to eight on XR40) of Model 670,

770, and 771 vacuum fluorescent, 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 XR40, XR20, or XRSuper6 keypad bus. Additionally, you can

connect one Model 738A Ademco Interface Module or one Model FA426 Wireless Receiver to the XRSuper6, XR20,

and XR40 keypad bus. You can connect an additional Model FA426 Wireless Receivers to the XR40 keypad bus.
