PROGRAM THE PANEL
Assign the Form C relays to outputs in Output Options and Zone Information, or assign the relays to Zone
Alarm Actions. For example, program the panel Telephone Trouble Output to operate output 520so that a
trouble on the panel phone line would toggle relay 1on a module set to address 520. Output 521would toggle
relay 2on the same 716module. The module’s four Form C relays are rated for 1Amp at 30VDC resistive. For
more information about programming, refer to the appropriate panel programming guide.

ADDITIONAL INFORMATION
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 10 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).
Supervised Operation
To install the module as a supervised device, connect all four LX‑Bus wires from the module to the panel LX‑Bus and
program an appropriate zone as a Supervisory (SV) type. The module may use any address for supervision, provided
that a Supervisory zone is programmed for that address. For example, zone 504on an XR550Series panel would be
programmed as an SV zone to supervise a 716module set to address 04on the first LX‑Bus. Only the first zone number
for the programmed device is supervised. Refer to Table 1.
When installing Zone Expansion Modules on the same LX‑Bus as a supervised 716Module, address the Zone Expanders
to the next zone number. For example, on an XR550Series panel, the zone is 520for supervision and 521for a zone
expander on the same bus.
If a supervised 716Module loses communication with the panel, an open condition (Trouble) is indicated on its
Supervisory zone.
Unsupervised Operation
To operate the module in unsupervised mode, do not connect the yellow wire from the module to the panel LX‑Bus.
Unsupervised operation allows you to install multiple modules and set them to the same address. Do not program a
zone address for unsupervised operation. Unsupervised operation is incompatible with fire listed installations. For more
information, refer to “Compliance Listing Specifications”.
Annunciator Outputs (Switch‑to‑Ground)
Unlike the module Form C relays, the four power limited annunciator outputs on the 716Module follow the zone state
having the same address. For example, output 1 (white/brown) on a 716module set to address 120shorts to ground each
time zone 120is in alarm or trouble while armed. Use this feature to operate relays or LEDs to show changes in the state
of the panel armed zones. Refer to Table 2.
