DMP Electronics 481 Installation Sheet

Description

The 481 Expansion Interface Card allows you to expand the XR200 panel by up to 100 additional hardwire zones. The
481 provides one 4-wire LX-Bus™ connection that supports combinations of the 711, 714, and 715 Zone Expanders,
716 Output Expanders, and 717 Graphic Annunciator Modules.
You can also connect the single point 5845LX ShatterPro Glassbreak Detector, 6155LX SharpShooter PIR, 521LX/
521LXT Smoke Detector, and the 867 Addressable Notification Module to the LX-Bus.
The XR200 panel can support up to 200 zones of protection on multiple LX-Buses when using the 460 Interface
Adaptor Card and two 481 Expansion Interface Cards. The 481 can also be used with the 462N, 462FM, 462P , and 472
interface cards.

Installation Safety

Ground Yourself Before Handling the Panel! Touch any grounded metal, such as the enclosure, before
touching the panel to discharge static.
Remove All Power From the Panel! Remove all AC and Battery power from the panel before installing
or connecting any modules, cards, or wires to the panel.

Installing the 481 Card

1. Remove AC and battery power from the XR200 panel before installing the 481 card.
2. Align the 50 pin connector of the 481 with the J6 connector on the XR200 panel.
3. Press the 481 onto the J6 connector while applying even pressure to both sides of the board.
4. Connect the LX-Bus wiring to the harness supplied with the module.
5. Insert the harness connector into the LX-Bus header on the bottom of the 481 card.
6. Restore power to the panel.

Connecting Devices to the 481

The 481 card contains a 4-wire LX-Bus harness to which you connect the hardwire LX-Bus devices detailed above. The
harness plugs into a 4-pin header located on the bottom of the 481 card. Connect the 4-wire LX-Bus wiring to the
harness as shown in Figure 1. All four wires are used.
Note: Do not use shielded wire when using the LX-Bus.

Wiring Specifications

When planning an LX-Bus installation, keep in mind the
following four specifications:
1. You can install individual keypads on wire runs of
up to 500 feet using 22 gauge wire or up to 1,000
feet using 18 gauge wire. To increase the wire
length or add additional devices, a power supply is
required.
2. Maximum distance for any one keypad bus circuit
(length of wire) is 2,500 feet regardless of the
gauge of wire. This distance can be in the form of
one long wire run or multiple branches with all
wiring totaling no more than 2,500 feet.
3. Maximum number of devices per 2,500 feet circuit is 40. (Note: Each panel allows a specific number of
supervised keypads. Additional keypads can be added in the unsupervised mode. Refer to the panel's
installation guide for the specific number of supervised keypads that are allowed.)
4. Maximum voltage drop between the panel (or auxiliary power supply) and any device is 2.0 VDC. If the voltage
at any device is less than the required level, an auxiliary power supply should be added at the end of the
circuit.
Refer to the 710 Module Installation Sheet (LT-0310) for more information. Also see the LX-Bus/Keypad Bus Wiring
Application Note (LT-2031).
