REFERENCE
UL Commercial Fire
The 734 Interface Module must be used in conjunction with at least one DMP 630F keypad.
Any Auxiliary Power Supplies must be regulated, power limited, and listed for Fire Protective Signaling Service.
UL Access Control
The access relay must be configured as fail-safe or fail-secure as determined by the local Authority Having Jurisdiction
(AHJ). This system is not intended to be used in place of listed panic hardware.
The power supply must be a listed commercial burglary/household fire, power limited, Class 2 with a compatible
voltage range for the product. The 734 requires a 12 or 24 VDC power source.
UL Commercial Burglary (XR150/XR550 Series Panels)
When using the zones of the 734 in a listed application, place the module in a listed enclosure and connect a DMP
Model 307 Clip-on Tamper Switch to the enclosure programmed as a 24-Hour zone.
The 734 Access Control features have not been investigated by ULC.
The 734 zones can be used in a Low Risk application. For Medium or High Risk applications, refer to the Dual Zone
Protection diagram in the XR150/XR550 Canadian installation guide.
Keypad Bus Wiring Specifications
▶
DMP recommends using 18 or 22-gauge unshielded wire for all keypad and AX-Bus/LX-Bus circuits. Do not
use twisted pair or shielded wire for AX-Bus/LX-Bus and Keypad Bus data circuits. All 22-gauge wire must be
connected to a power-limited circuit and jacket wrapped.
▶
On Keypad Bus circuits, to maintain auxiliary power integrity when using 22-gauge wire do not exceed 500 ft.
When using 18-gauge wire do not exceed 1,000 ft. To increase the wire length or to add devices, install an
additional power supply that is listed for Fire Protective Signaling, power limited, and regulated (12/24 VDC
nominal) with battery backup.
▶
Maximum distance for any one bus circuit (length of wire) is 2,500 ft regardless of the wire gauge. This
distance can be in the form of one long wire run or multiple branches with all wiring totaling no more than
2,500 ft. As wire distance from the panel increases, DC voltage on the wire decreases. Maximum number of
AX-Bus/LX-Bus devices per 2,500 ft circuit is 40.
▶
Maximum voltage drop between the panel (or auxiliary power supply) and any device is 2 VDC. If the voltage at
any device is less than the required level, add an auxiliary power supply at the end of the circuit. When voltage
is too low, the devices cannot operate properly.
For additional information refer to the panel’s Installation Guide or the 710 Installation Sheet (LT-0310).
