DMP 711 Zone Expansion Module
The DMP 711 is a zone expansion module engineered to extend the capacity of access control systems without requiring core infrastructure replacement. It communicates over TCP/IP, a standard protocol in modern security networks, and integrates keypad readers to enable credential entry at expansion points throughout your facility.
Overview
Access control deployments often face capacity constraints as facilities expand or security requirements evolve. The 711 solves this by adding zone control points to existing systems via network connectivity — meaning you connect it to your network infrastructure rather than running dedicated wiring to a central panel. This approach reduces installation labor and simplifies future scaling.
The module operates at 15VDC, a voltage standard in security installations, simplifying power distribution and eliminating the need for proprietary or exotic supply specifications. If your facility already runs 15VDC power for other security devices, the 711 integrates cleanly into that same backbone.
Key Features
- TCP/IP Communication: Network-based connectivity means the 711 plugs into your existing Ethernet infrastructure. No proprietary cabling or serial daisy-chains — this reduces deployment complexity and allows the module to sit anywhere on your security network segment.
- Keypad Reader Support: The module accepts keypad readers, enabling PIN-based credential entry at each expansion zone. This is practical for facilities where badge readers alone are insufficient — you may need both card and PIN verification, or PIN-only access at certain points.
- 15VDC Operating Voltage: Compatibility with standard security power distribution means fewer supply units and simpler maintenance. Your power infrastructure doesn't need to be redesigned to accommodate this module.
- Zone Expansion Architecture: Each 711 module adds additional zone control capacity to your access control system, allowing you to extend security governance to new doors, gates, or checkpoints without replacing your core panel or controller.
- Integration with Existing Systems: The 711 is designed to work within established access control deployments. If your current system supports TCP/IP expansion modules, the 711 extends that capability.
Integration & Compatibility
Deployment success with the 711 depends on confirming that your access control system's controller or management platform supports TCP/IP-connected zone expansion modules. Review your current system documentation or consult with your integrator to verify compatibility before purchase.
The keypad reader interface allows you to assign different credential types and access rules to each expansion zone. This is valuable in multi-tenant facilities, warehouses, or campuses where different areas require different access policies.
For planning purposes, ensure your network has available bandwidth and that your Ethernet infrastructure reaches the intended mounting locations. A network switch with PoE (Power over Ethernet) capability may simplify power delivery, depending on your system configuration — though the 711's 15VDC requirement may require a separate power supply in some installations.
Frequently Asked Questions
Q: Can I use the DMP 711 to expand an older, non-networked access control system?
A: No. The 711 requires a controller or management system that supports TCP/IP-connected zone modules. If your existing system predates network connectivity or uses only serial expansion, the 711 will not be compatible. Consult your system documentation or contact your integrator.
Q: Does the 711 require a separate 15VDC power supply, or can it draw power from PoE?
A: The module is rated for 15VDC operation. Whether it can be powered via PoE depends on your specific installation and the capabilities of your network infrastructure. Confirm power delivery with your integrator before installation.
Q: Can I mix keypad readers and card readers on the 711?
A: The 711 is documented to support keypad reader integration. Compatibility with other reader types depends on your access control system's configuration and the specific reader models you plan to deploy. Verify reader compatibility with your system manufacturer.
Q: What is the maximum number of 711 modules I can add to a single access control system?
A: System capacity limits depend on your core controller or management platform. Refer to your controller's documentation for maximum zone and module expansion specifications.

The DMP 711 is a straightforward network-based zone expansion play. If your access control system already supports TCP/IP expansion, the 711 adds credential-entry capacity without forklift replacement of your core panel. The keypad reader architecture is the real value here — it gives you PIN verification at expansion points, which matters in environments where card-only access isn't sufficient for compliance or operational reasons.
Technical Highlights:
- TCP/IP Network Connectivity: Eliminates proprietary expansion cabling. The 711 sits on your standard Ethernet infrastructure, reducing installation time and allowing placement anywhere your network reaches — no cable runs back to a central panel.
- Keypad Reader Integration: Supports credential entry via PIN or combination. Valuable for dual-factor verification scenarios or PIN-only access rules at specific zones.
- 15VDC Standard Voltage: Operates on the same voltage backbone as most enterprise security systems. If your facility already distributes 15VDC to other access control gear, the 711 slots into that same power infrastructure without supply proliferation.
Deployment Considerations:
- Before you commit: confirm that your existing access control system's controller or software platform explicitly supports TCP/IP zone expansion. Older systems with only serial or relay expansion will not work with the 711.
- Power delivery matters. The 711 is rated for 15VDC operation. Verify whether your network switch, power distribution, or dedicated supply can reliably deliver 15VDC to each module location. In some installations, you'll need a small 15VDC supply near each expansion point rather than centralized power.
The 711 is a good fit for multi-zone facilities — warehouses, office parks, secure campuses — where a single access control system needs to reach multiple credential points but replacing the core panel is not on the roadmap. It's not a device for legacy analog expansion; it requires a modern, IP-aware controller. Size your deployment against your core system's maximum zone and module limits before provisioning multiple units.
