4 Independently Fused Outputs | Switched & Always-On DC Power | 12/24V Control Trigger | Fire Alarm Interface
The Inner Range 4-Way Switched DC Power Hub & Fire Door Release Relay IR-995916 is a professional 1-input, 4-output DC power distribution and switching module designed for electronic door locks, access control systems and fire alarm interface applications. Featuring four individually fused outputs, switched and always-on power connections, configurable normally open/normally closed control inputs, 12–24V DC trigger compatibility and a monitoring feedback relay, this versatile power hub provides controlled power distribution for commercial, industrial and high-security installations across Australia and New Zealand.
Developed by Inner Range, the IR-995916 provides a practical way to distribute power from a central DC supply while allowing an external control system to disconnect selected device power under programmed conditions.
The module is particularly suited to access-controlled doors using fail-safe electronic locking devices that must release when the applicable fire alarm or emergency release system activates.
Each of its four separately fused output channels provides both a switched power connection and an unswitched, always-on connection. This allows the installer to select the appropriate supply behaviour for the connected locking device or auxiliary equipment.
A common control input accepts external signals from compatible fire alarm panels, access control systems or other supervisory equipment. The input can be configured to respond to normally open or normally closed dry contacts, or to supported 12V/24V DC control signals.
The module also includes a feedback relay with normally open and normally closed contacts, enabling a connected monitoring system to detect the commanded switching state of the outputs.
With dedicated fuse-failure indicators and flexible trigger options, the IR-995916 simplifies multi-door lock power arrangements and supports integration with properly engineered emergency door release systems.

Modular Technology & Security Solutions
What's Included in the Box
- 1 × Inner Range 4-Way Switched DC Power Hub & Fire Door Release Relay – IR-995916.
Any manufacturer-supplied mounting or connection accessories should be confirmed with the supplier.
Not included: External DC power supply, backup batteries, electronic door locks, fire alarm controller, access control controller, cabling and enclosure unless separately specified.
Power Distribution and Switching Functions
The IR-995916 provides four output channels from one common supply, with both switched and unswitched terminals available at each channel.
Switched DC output connections
The switched connection on each channel is intended for devices whose power supply must be removed in response to the configured control input.
For example, a compatible fail-safe magnetic lock can be connected through the switched supply so that the control system can interrupt lock power during an approved fire-release condition.
Always-On DC output connections
Each channel also provides an unswitched connection for devices requiring continuous DC supply independent of the common switching command, subject to the power source and channel protection arrangements.
Common trigger input
The common control input allows a compatible external device to command the switched output state. Supported triggering options include normally open or normally closed dry contacts and 12–24V DC signals.
Feedback relay and fuse indication
The feedback relay provides an indication of the switched output state to compatible monitoring equipment. Individual fuse-failure indicators assist with fault identification.
The feedback relay should not be treated as proof that an individual lock has physically released. Separate door or lock position monitoring may be required for that purpose.
Practical Use Scenarios
Fire alarm and electronic lock integration
Interface compatible fire alarm system control signals with fail-safe door locking circuits so that lock power can be removed under designated emergency conditions.
Commercial office buildings
Distribute DC power to multiple access-controlled doors from a central supply while supporting common lock release operation.
Industrial and warehouse facilities
Provide fused power distribution for compatible door locking equipment in restricted or monitored areas.
Educational and healthcare facilities
Support professionally designed access control installations where emergency egress requirements must be coordinated with fire safety systems.
Multi-door access control installations
Simplify centralised power distribution for up to four separately fused output circuits.
Security system maintenance
Provide a dedicated power distribution interface with individual fuse-failure indication and feedback monitoring to support troubleshooting and servicing.
Installation and Safety Considerations
The Inner Range IR-995916 is designed to be integrated into a properly engineered DC power distribution and electronic door locking arrangement.
An installer must verify the supply voltage, available current, individual fuse ratings, connected lock requirements and total load before energising the module.
For fire-release applications, the external fire alarm system must be correctly interfaced so that the intended emergency release function operates under the required conditions.
Important: The IR-995916 is not a complete fire safety system, certified emergency exit solution or substitute for an approved emergency egress design. Its use must be assessed against the applicable building and fire safety requirements, including the operation of fail-safe locks, emergency release devices and power failure conditions.
Fire door release functionality must be tested during commissioning and as required by the applicable maintenance regime.
Warranty Information
The Inner Range 4-Way Switched DC Power Hub IR-995916 is subject to applicable manufacturer warranty conditions and statutory consumer guarantees in Australia and New Zealand.
The exact manufacturer warranty duration has not been independently confirmed. Warranty claims may be coordinated through the supplying distributor and Inner Range, subject to the applicable terms.
