DMP 1158 Wireless 8-Zone Input Module
The DMP 1158 is a wireless zone input module that bridges the gap between legacy hardwired perimeter protection and modern wireless deployments. Designed for installations where running cables to door and window contacts is impractical, cost-prohibitive, or temporary, the 1158 gives you eight independent zone inputs operating at 12VDC — no separate power supply required in many configurations.
Key Features
- Eight Independent Zone Inputs: Each zone can monitor a separate door or window contact, giving you flexible perimeter coverage. Useful for retrofits where you're adding security to an existing structure without breaking walls or running new conduit.
- Wireless Connectivity: Eliminates the need for hardwired zone runs to your control panel. This is particularly valuable in temporary deployments, leased facilities, or warehouses where wiring changes incur facility charges.
- 12VDC Operation: Lower voltage means safer installation compared to mains power, and simpler integration with existing DMP control panel architectures.
- Retrofit-Ready: The 1158 pairs well with existing DMP security ecosystems, making it a practical choice when you're expanding zone capacity without replacing your core panel.
Integration & Compatibility
The 1158 integrates with DMP control panels and third-party systems that support wireless zone input modules. Before ordering, verify that your control panel's wireless receiver is compatible with DMP 1158 protocols and that your facility's RF environment won't introduce false triggers. Buildings with heavy metal shielding or dense wireless congestion (hospitals, manufacturing floors with industrial RF equipment) may require site survey testing to ensure reliable zone transmission.
Installation is straightforward for retrofit and temporary deployments. You'll mount the module near the zones it monitors, wire each door or window contact to the appropriate input terminal, and configure the wireless pairing on your control panel — no conduit work required. For facilities requiring wireless expansion options, the 1158 scales more easily than hardwired alternatives.
Deployment Considerations
The 1158 works best when zone contacts are within reliable RF range of your receiver. Obstructed RF paths, metal-framed doors, or distance beyond the receiver's stated range can cause zone dropout — not a failure of the module itself, but a limitation of wireless. In high-interference environments, a site survey before deployment is time well spent. Battery-backed contacts should be monitored separately; verify that your system supports supervised wireless zones if battery health is critical to your alarm response chain.
For security system design, weigh wireless convenience against the latency and RF dependency trade-offs. Hardwired zones remain the gold standard for life-safety applications where sub-100ms response is required; wireless is better for cost and flexibility in retrofit or temporary scenarios.
Frequently Asked Questions
Q: Does the DMP 1158 work with non-DMP control panels?
A: The 1158 is designed for DMP panels. Compatibility with third-party systems depends on whether those systems support DMP wireless zone protocols. Verify with your panel manufacturer before purchasing.
Q: What's the wireless range of the 1158?
A: Refer to the datasheet for exact range specifications. Range varies with RF environment, building materials, and receiver antenna placement. A site survey is recommended for installations exceeding 100 feet or with metal shielding.
Q: Can I mix the 1158 with hardwired zones on the same panel?
A: Yes. DMP control panels support hybrid configurations. You can run some zones hardwired and others through wireless modules like the 1158 on the same panel.
Q: Is battery backup included with the 1158?
A: The 1158 itself does not include onboard battery. Battery-backed operation depends on your control panel and its power supply configuration. Verify your panel's backup capacity if zones must remain supervised during mains power loss.
Q: How many 1158 modules can I connect to one control panel?
A: Panel capacity depends on the specific DMP model and wireless receiver. Check your panel's technical documentation for maximum zone count and wireless module limits.

The DMP 1158 fills a real need in retrofit security — I've deployed these in warehouses and leased retail spaces where running cable was impossible or too expensive. Eight independent zones at 12VDC means you get solid perimeter coverage without the hassle of conduit work. The wireless architecture eliminates the single biggest cost factor in zone expansion: labor and facility coordination.
Technical Highlights:
- Eight Zones per Module: Each zone is independent, so you're not multiplexing inputs — a genuine expansion of your panel's available zone count without replacing the panel itself.
- 12VDC Low-Voltage Operation: Safer to install than mains-powered alternatives, and integrates cleanly with DMP backup power architectures. No isolated 24VDC transformer required.
- Wireless Simplicity: Eliminates conduit, trenching, and multiple site visits for cable runs. Particularly valuable when the building owner charges per modification or when you're working in occupied facilities.
Deployment Considerations:
- RF environment matters — metal-framed buildings, industrial RF interference, or distance beyond receiver range will degrade zone reliability. Always do a site survey before committing to wireless-only perimeter on a critical facility.
- Wireless zones introduce latency and dependency on receiver uptime. Hardwired zones remain superior for life-safety and high-response-speed scenarios.
Best suited for retrofit expansions, temporary deployments, and leased facilities where wiring changes incur cost or facility friction. Less ideal for mission-critical perimeter protection on newly constructed buildings — hardwired zones are still the right call there.
