2N 01257-001 IP Verso I/O Module
The 2N 01257-001 is a compact I/O expansion module designed to extend the control and integration capabilities of 2N IP Verso intercom systems. This accessory mounts directly underneath the main IP Verso unit without consuming additional mounting real estate—a significant advantage in space-constrained installations like office lobbies, retail entry points, or residential building vestibules.
Key Features
- 2 Logical Inputs: Detect signals from external sensors, door contact switches, or alarm zone loops. Logical inputs interpret voltage state changes, allowing you to monitor multiple conditions (door open/close, motion, tamper, button press) without adding separate monitoring hardware.
- 2 Relay Outputs: Switch up to rated current to control door strikes, electric latches, gate operators, or building automation relays. Relay outputs give you direct electromechanical control—no intermediary gateway or networked smart switch required—which matters when response speed and reliability are critical.
- Undercarriage Mount Design: Installs directly beneath the IP Verso main module. This stacking approach eliminates the need for separate enclosures, cable runs between units, or additional wall/floor space. Particularly valuable in high-density entry scenarios (multi-tenant buildings, data centers, warehouse access points) where every mounting position counts.
- Seamless IP Verso Integration: The module is provisioned as part of the IP Verso ecosystem. Configuration happens through the same management interface as the main unit—no separate software, no OSDP gateway appliance, no third-party software licensing. This reduces deployment complexity and training overhead.
- Access Control and Automation Ready: Connect door locks, gate operators, barrier controls, and alarm inputs directly. The 01257-001 bridges IP intercoms and traditional electromechanical or hardwired security devices, allowing existing door hardware and sensors to remain in service without replacement.
- Event-Triggered Response Capability: Combine input detection with relay activation rules. For example: detect a button press (input), trigger a door strike (relay output), and log the event through the IP Verso system—all without external scripting or additional controllers.
Integration & Compatibility
The 01257-001 is designed exclusively for 2N IP Verso intercom systems. Verify compatibility with your specific IP Verso model and firmware version before ordering. Integration relies on the standard access control integration features built into IP Verso—no external gateways, no proprietary middleware. If you are planning a deployment that includes 2N intercoms with door control and sensor monitoring, the 01257-001 eliminates the need for a separate I/O controller or PLC in many scenarios.
For larger deployments requiring more than 4 total I/O points (2 in + 2 out), plan additional modules or explore dedicated access control panels with higher I/O density and more sophisticated logic options.
Deployment Considerations
Space efficiency is the primary benefit—mount once, configure through IP Verso. Current rating on relay outputs should be verified against your lock or automation load; consult the datasheet for exact specifications. Input sensitivity and debounce timing are configured through the IP Verso management interface, so familiarity with that platform is expected. For installations requiring isolated power supplies or galvanic isolation between input/output circuits, validate isolation specifications against your design.
Frequently Asked Questions
Q: Can the 01257-001 be used with IP Verso models other than the base unit?
A: The module is designed to stack underneath the IP Verso intercom. Confirm your specific IP Verso model supports undercarriage expansion before purchase.
Q: What is the maximum voltage and current rating on the relay outputs?
A: Relay switching capacity must be verified in the full technical documentation. Do not exceed manufacturer specifications for load current, as undersizing can cause premature contact wear or failure.
Q: Does the 01257-001 require OSDP or only work with native IP Verso control?
A: The module integrates natively with IP Verso and does not require a separate OSDP gateway. Control is managed through the standard IP Verso management interface.
Q: Can inputs be configured for momentary or sustained signal detection?
A: Configuration options (pulse duration, debounce, logic inversion) are set through IP Verso settings. Verify your firmware version supports the specific input mode you require.
Q: What happens to relay outputs if the IP Verso loses power or network connectivity?
A: Relay behavior during power loss or network interruption should be specified in the installation guide. Confirm fail-safe vs. fail-secure requirements match your security posture before deployment.
Q: Is the module compatible with third-party building automation or alarm monitoring systems?
A: The 01257-001 is designed for native IP Verso control. Integration with external systems depends on whether IP Verso itself supports those systems through webhooks, syslog, or other APIs—not through direct module connections.

The 2N 01257-001 solves a real problem in IP Verso deployments: how to add door and sensor control without adding floor space or introducing external I/O hardware. The 2-input / 2-output configuration is modest but purposeful—sufficient for single-door access points, gate operator control, and basic alarm zone monitoring in small-to-medium office and retail builds.
Technical Highlights:
- Compact Form Factor: Undercarriage mount means no separate DIN rail, no enclosure, no additional cabling runs. In a busy lobby or retail vestibule where wall and floor space is already claimed by readers, keypads, or video intercom housings, this stacking approach eliminates installation friction and reduces punch-list items.
- Native IP Verso Control: No OSDP gateway, no separate I/O controller license, no multi-vendor firmware management. Configuration is native to the IP Verso management interface. Provisioning time drops from hours to minutes if the IP Verso is already deployed and staffed.
- Relay Output Flexibility: Two relay outputs handle lock strikes, gate operators, and low-current automation loads. Verify load specifications in the datasheet—undersizing or exceeding relay ratings is a common field failure point. Current capacity should be confirmed against your specific hardware (mag lock, solenoid, motor contactor).
Deployment Considerations:
- I/O density is the limiting factor. If a single access point requires more than 4 total connections (2 in + 2 out), the 01257-001 will not scale without adding additional modules or switching to a higher-density access control panel. Plan ahead for multi-door builds.
- Watchout: Relay behavior during network loss or power failure is installation-critical. Confirm fail-safe vs. fail-secure requirements with your security officer before wiring door hardware. A power loss that leaves a relay energized (or de-energized) could create a security gap or lock occupants inside.
- Input signal debounce and sensitivity are managed through IP Verso firmware. Test with your actual door contact switches and sensor hardware before going live—noisy signals or slow switch action can trigger false events.
The 01257-001 is the right choice for small IP Verso installations where space is tight and door control is essential but not complex. Skip it if you need more than 4 I/O points, require isolated power supply domains, or are integrating third-party building automation systems that don't speak IP Verso natively. For those scenarios, a standalone access control panel with higher I/O density and more flexible programmability will save integration time and reduce troubleshooting overhead.
