Aico Ei411H RadioLINK Alarm Control Switch

The Aico Ei411H RadioLINK Alarm Control Switch provides convenient remote control of interconnected smoke, heat and multi-sensor fire alarms from one accessible location. Its three clearly marked controls allow users to test the complete alarm system, locate the alarm that initiated an activation and silence a confirmed nuisance alarm.

The Ei411H communicates wirelessly using RadioLINK technology, eliminating the need for interconnection cabling. Its House Code feature restricts communication to devices assigned to the same system, helping prevent interference with neighbouring alarm installations.

Powered by sealed, tamper-resistant lithium cells with a life of over ten years under normal operating conditions, the Ei411H provides a completely wire-free installation. It is intended exclusively for fire-only systems; the Ei450 Alarm Controller should be used where fire and carbon monoxide alarms are combined.
