## Summary description

Triton EXP-I8-RN expansion module (MPN 5403, EAN 5907565617245) is an input/output expander designed to increase the number of inputs and outputs on compatible alarm and control panels. It provides additional zones and relay outputs for sensors, detectors and control circuits. Suitable for integrating extra detectors, tamper inputs or output-driven devices in security and access systems.

## Long description

The Triton EXP-I8-RN expansion module is an input/output expander designed to increase the number of inputs and outputs on compatible alarm and control panels. It provides additional zones and relay outputs to integrate sensors, detectors and control circuits into existing security and access control systems. The module is intended for use where extra detector inputs, tamper monitoring or output-driven actuators are required without replacing the main panel.
Advantages
The module expands system capacity while maintaining compatibility with supported Triton control panels and follows standard wiring and signaling conventions. Its compact design allows installation in equipment cabinets or distribution enclosures close to sensors and actuators, reducing cable runs. The unit supports both additional input zones and relay outputs for flexible configuration of alarm zones and control lines.
Suitable for
 Expanding alarm system zone count to add more detectors
 Providing additional relay outputs for control of locks, sirens or lighting
 Integrating tamper or supervisory inputs from remote devices
 Retrofitting legacy panels that need extra I/O without panel replacement
Key specifications
 Function: input/output expansion module for alarm and control panels
 Inputs: additional dedicated sensor/detector input lines (digital)
 Outputs: relay outputs suitable for control of external devices
 Form factor: compact module for mounting in enclosures or racks
 Wiring: terminal block connections for inputs, outputs and power/signal bus
How to use
Install the expansion module inside an appropriate enclosure near the devices to be connected, and wire the inputs and outputs to the panel’s communication bus or expansion connector according to the panel manufacturer’s wiring diagram. Connect sensor and tamper lines to the designated input terminals and external devices such as locks or sirens to the relay output terminals. Ensure correct power connection and observe polarity where required. After physical installation, configure the main control panel to recognize and assign the added inputs and outputs according to the panel’s configuration interface.
Usage recommendations
Use shielded cables for long runs to reduce interference, mount the module in a dry, ventilated location away from strong electromagnetic sources, and follow the main panel’s installation manual for bus addressing and configuration steps. Verify all connections and test each input and output after configuration before placing the system into service.
