Aico Ei129 Hard Wired Switched Input Alarm Trigger Module

Integrate External Devices into Your Aico Fire Alarm System

What It Does
The Ei129 triggers the alarms in a system if an external device is activated, such as a sprinkler system. This hard-wired switched input module acts as a bridge between your interconnected Aico alarms and external safety equipment, creating an automated response system that activates all connected alarms instantly when your external device sends a signal.

Automatic Activation & Seamless Reset
When the volt-free contacts connected to the Switched Input Module are closed, all interconnected smoke, heat and CO alarms will sound, and when the device triggering the Switched Input Module resets it will automatically reset and all interconnected alarms will cease sounding. There's no manual intervention required—your system responds automatically and returns to standby mode as soon as the triggering event ends.

Reliable Backup Power When You Need It Most
The Switched Input Module runs on 230V AC mains power and has built-in tamper proof rechargeable Lithium cells that act as a battery back up in the event of mains failure, designed to have a 10-year life and outlast the life of the module itself, whilst providing up to 2 months of operation without mains power. This ensures your alarm system continues to monitor and respond to external triggers even during power outages.

Flexible Installation Options
Supplied with an easi-fit base to make it quick and simple to install, the Ei129 alarm trigger module is designed to set off a Fire Alarm across your home network if another connected device is activated. The Ei129 is designed to be either remotely sited or can be fitted under a Smoke/Heat Alarm by removing the cover plate and mounting the alarm base plate onto the unit. Whether you choose to mount it independently with its cover or stack it beneath an existing alarm, installation is straightforward with easi-fit bases and flexible mounting configurations.

Broad System Compatibility
Any combination of 3000, 2110e, 160e and 140RC and 260 Series smoke, heat and CO alarms can be interconnected to a maximum of 20 units. The module works with Aico's full range of mains-powered fire detection solutions, giving you flexibility in building or expanding your system.

Built for Professional Standards
The device is approved to BS EN60065:2002/A1:2006 and is CE marked. Your system meets rigorous safety standards, ensuring compliance with regulations and industry best practices.

Typical Applications
Beyond sprinkler systems, the Ei129 connects to any volt-free closing contacts rated at 230V AC—making it ideal for integrating fire suppression systems, alarm control panels, and other automated safety equipment into a unified fire alarm network. Multiple modules can be used on the same system for comprehensive protection across different zones or devices.
