Exit Programming

Remove the jumper from the PROGRAM header to exit 738A programming mode. Place the jumper over one pin for

future use. Remove the Model 330 cable and the DMP keypad from the PROG header. After exiting the programming

mode, all zone states report to the panel as normal. Always test and verify all zones for proper communication.

ADDITIONAL INFORMATION

Wiring Specifications

The maximum wire distance between the Ademco™ wireless receiver and the module is 3 feet. Refer to the following

LX‑Bus and Keypad bus wiring specifications.

DMP recommends using 18 or 22 AWG for all LX‑Bus and Keypad Bus connections. The maximum wire distance between

any module and the DMP Keypad Bus or LX‑Bus circuit is 1,000 feet. To increase the wiring distance, install an auxiliary

power supply, such as a DMP Model 505‑12. Maximum voltage drop between a panel or auxiliary power supply and any

device is 2.0 VDC. If the voltage at any device is less than the required level, add an auxiliary power supply at the end of

the circuit.

To maintain auxiliary power integrity when using 22‑gauge wire on Keypad Bus circuits, do not exceed 500 feet. When

using 18‑gauge wire, do not exceed 1,000 feet. Maximum distance for any bus circuit is 2,500 feet regardless of wire

gauge. Each 2,500 foot bus circuit supports a maximum of 40 LX‑Bus devices.

For additional information refer to the LX‑Bus/Keypad Bus Wiring Application Note (LT‑2031) and the 710 Bus Splitter/

Repeater Module Installation Guide (LT‑0310).

Keypad and LX‑Bus Connection

For simple installation, the module connects to the panel 4‑wire keypad data bus. The module can also connect to the

on‑board LX‑Bus of an XR150/XR550 Series panel.

XR150/XR550 Series

Connect the module directly to the Keypad Bus or the LX‑Bus (LX500‑LX900) connectors on the panel.

Note: When programming module zones on the LX‑Bus select NO at the Wireless option in the Zone Information

section of panel programming.

738A LED Operation

The green LED on the module indicates data transmission to the panel.

•

On—There are no transmitters programmed

•

Off—The module is not being programmed or it is not responding to the panel
