Step 1: Mount the 734

The back and ends of the 734 housing have wire entrances. The back also contains multiple mounting holes that allow

you to mount the module on a single‑gang switch box. DMP recommends mounting the 734 near the protected door.

1. Remove the PCB from the plastic housing by loosening the clips on

one side and gently lifting it out of the housing base.

2. Insert the included screws in the desired mounting hole locations

and tighten them to secure the housing to the surface.

3. Reinstall the PCB in the housing base.

Step 2: Wire the Access Control Lock

The Form C relay draws up to 35 mA of current and contacts are rated for

10 Amps (resistive) at 12/24 VDC. When connecting multiple locks to the

Form C relay, the total current for all locks cannot exceed 10 Amps. The

three relay terminals marked NO C NC allow you to connect the device

wiring to the relay for module control. Use an additional power supply to

power magnetic locks and door strikes.

The 734 Access Control Module is a device designed to integrate access control functionalities into a security system, allowing for the management of doors, card readers, and various zones. It serves as an interface between the main control panel and the access control components, facilitating communication and control.

Function Description

The module's primary function is to provide access control capabilities, including the control of door locks (magnetic locks or door strikes), the integration of card readers (Wiegand and OSDP), and the monitoring of security zones. It receives data from the main panel via a Keypad bus or AX-Bus and transmits data to other keypads or modules. The module features a Form C relay for controlling door locking mechanisms, status indicator outputs, and multiple zone inputs for monitoring. It also includes a keypad programming header for configuration and a piezo for audible indications.

Important Technical Specifications

Relay Specifications: The Form C relay can draw up to 35 mA of current. Its contacts are rated for 10 Amps (resistive) at 12/24 VDC. When multiple locks are connected to the Form C relay, their total current must not exceed 10 Amps. For devices exceeding 10 Amps, an isolation relay is required.
Power Supply: The 734 can be powered by either a 12 VDC or 24 VDC power supply. The 12 VDC power can be sourced from the panel keypad bus or a separate power supply. The 24 VDC power supply can be connected directly to the relay terminal block (J1).
Output Current Limit: The total output current for zones connected to the module must not exceed 750 mA to prevent equipment damage.
Zone Inputs: The module includes multiple zone inputs:
- Zones 1-3 (Terminals 8-12): These are grounded zones and cannot be used for fire-initiating devices. Zones 2 and 3 offer specific access control functionalities, with Zone 2 providing a bypass feature and Zone 3 offering request-to-exit functionality.
- Zone 4 (Terminals 13-14): This is a non-powered Class B ungrounded zone suitable for connecting fire devices such as heat detectors or pull stations.
Card Reader Output: The 734 provides direct 12/24 VDC output to the reader via the RED terminal connection.
Wiegand Card Reader Connections:
- Data Zero (DO): Green wire
- Data One (D1): White wire
- 12/24 VDC: Red wire
- Ground: Black wire
OSDP Card Reader Connections:
- Data Transmission (A 485-): GRN terminal
- Data Transmission (B 485+): WHT terminal
- Reader Power (DC+): RED terminal
- Reader Power (DC-): BLK terminal
Suppressor: A 333 suppressor is included to mitigate surges caused by energizing magnetic locks or door strikes. It should be installed across the module's C (common) and NO (normally open) or NC (normally closed) terminals, depending on the relay connection.
End-of-Line (EOL) Resistors: Supplied 311 1k Ohm EOL resistors are used on each zone.
KYPD OUT Header: When the 734 is powered from 24 VDC, no devices should be connected to the KYPD OUT header.

Usage Features

Flexible Mounting: The module's housing has wire entrances at the back and ends, and multiple mounting holes allow for installation on a single-gang switch box. It is recommended to mount the 734 near the protected door for optimal performance.
Door Lock Control: The Form C relay allows for direct control of magnetic locks or door strikes. Wiring diagrams are provided for both normally closed (magnetic lock) and normally open (door strike) configurations, emphasizing the need for an additional power supply for these devices and the use of a suppressor.
Card Reader Integration: Supports both Wiegand and OSDP card readers, with clear wiring instructions for each type, including data and power connections.
Zone Monitoring: Provides multiple zone inputs for various security applications. Zones 2 and 3 are specifically designed for access control features like bypass and request-to-exit, while Zone 4 is suitable for fire devices.
Address Setting: The module's address is set using DIP switches on the PCB, allowing for unique identification within the system.
Panel and Module Programming: The device requires programming of both the panel and the 734 module itself, with instructions available via a QR code or the panel's programming guide.
Daisy-Chaining: The KYPD OUT header allows for connection to other keypads or modules, supporting a maximum number of devices. A dual-connector harness is required for this feature.
Reset Functionality: While the panel can perform a Sensor Reset, it does not drop power to the Keypad Bus or AX-Bus. For four-wire smoke detectors or other latching devices on Zone 4, a mechanical means of resetting is required.

Maintenance Features

PCB Removal: The PCB can be easily removed from the plastic housing by loosening clips, facilitating installation and maintenance.
Suppressor Installation: The included 333 suppressor helps protect the module from power surges, contributing to the longevity and reliability of the device.
EOL Resistors: The use of EOL resistors on each zone is a standard practice for maintaining circuit integrity and simplifying troubleshooting.
Clear Wiring Diagrams: The manual provides detailed wiring diagrams for various components, aiding in correct installation and future maintenance.
Troubleshooting Guidance: The note regarding the mechanical reset for Zone 4 devices and the caution about the KYPD OUT header when using 24 VDC power provide important considerations for preventing issues and ensuring proper operation.
