Instantly activate external devices when your alarm system triggers — the Aico Ei128R Hard Wired Relay Module is designed to switch on ancillary equipment like strobe lights, door closers, extractors, and telecare devices the moment your smoke, heat, or CO alarm sounds. This mains-powered module acts as the critical link between your alarm system and any high-power devices that require a relay switch to operate safely. Flexible operation modes for different applications — Choose between Continuous mode (signal stays active while the alarm sounds) or Pulse mode (automatic 5-second signal). This flexibility lets installers configure the relay for specific use cases, whether you're triggering a door release system that needs immediate activation or a notification device that works better with timed pulses. Volt-free contacts rated for 240V AC / 5 Amps — The module includes Normally Open and Normally Closed contacts as standard, meaning it works with virtually any voltage configuration. You can configure it to deliver either 230V or 24V output (using an external 24V supply), making it compatible with a wide range of existing equipment regardless of voltage requirements. This electrical isolation protects your alarm circuit while safely controlling high-voltage devices. Simple installation beneath existing alarm bases — The compact disc-shaped design (135mm diameter) mounts directly underneath Aico smoke and heat alarm bases, eliminating the need for separate wiring conduits or additional mounting hardware. It includes trunking knock-outs for both surface-mounted and recess installations, plus a supplied cover for remote siting if you need to position the relay away from the alarm unit. The 4-way connector block makes wiring straightforward, even for complex interconnected systems. Works with multiple alarm systems simultaneously — Compatible with Aico 3000, Ei2110e, 160e, 140RC, and 260RC Series alarms. You can network up to 12 units total in a single interconnected alarm system, allowing coordinated relay activation across multiple zones or floors in larger properties. When any interconnected alarm triggers, the relay contacts instantly switch. Mains-powered with built-in battery backup — Operating on 230V AC power, the module includes tamper-proof rechargeable lithium cells that provide up to 2 months of operation if mains power fails—keeping critical safety devices active during emergencies when power is unavailable. These cells are designed to last 10 years, outlasting the module itself. Engineered by installers, built by Aico — Manufactured in Ireland and developed with professional installer feedback, this module reflects real-world requirements for reliable fire safety systems. It's built to handle the demands of commercial properties, care facilities, and multi-unit residential installations where triggered external devices are part of the safety protocol.
