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, and 16 points to the XR20 and XRSuper6.
3.2 Wiring Diagram
The system wiring diagram in Figure 1, on the following page, shows some of the accessory devices 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. 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 vacuum
uorescent, LCD, or LED keypads to the 4-wire keypad data bus provided by the panel on terminals 7, 8, 9,
and 10. Also, you can connect Model 712-8 714, 715, 714-8, 714-16, 715-8, 715-16 Zone Expansion Modules
to the keypad bus. Additionally, you can connect one Model 738A Ademco Interface Module or one Model
FA426 Wireless Receiver to the keypad bus. You can connect one additional Model FA426 Wireless Receiver
to the XR40 keypad bus.
