Introduction

System Components

3.1Description

The DMP 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 6.5 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.

3.2Wiring diagram

The XR10/XR20 system below 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 XR20.

3.3Lightning protection

Metal Oxide Varistors and Transient Voltage Suppressors help protect against voltage surges on input and output circuits of the XR10. Additional surge protection is available by installing the DMP 370 or 370RJ Lightning Suppressors.

3.4Security Command® keypads

You can connect any combination of up to four Model 670, 770, and 771 vacuum fluorescent, 690, 693, 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. (Note: The XR10 does not support zone expansion on the keypad bus.)
