This is the Aio Ei171RF, a hard of hearing strobe fire alarm ideal for the hearing impaired and deaf. An Aico RadioLINK-enabled visual alarm designed for deaf and hard-of-hearing users who may be unable to hear a conventional auditory sounder.

Please note: this item is non-returnable; due to the nature of this item, it has an electronic component and sensor, and we cannot take this item back for a refund as "unwanted".

This alarm kit includes a high-intensity strobe light with a specially designed wide-angle lens, and it supports input from and output to other accessories via two auxiliary sockets, such as vibration discs, auto-diallers and alarm clocks. 

The alarm does not contain a sensor and so requires a connection to an Aico RadioLINK-enabled smoke/heat detector. The Ei171 alarm is mains-powered and incorporates a rechargeable backup battery in the event of mains failure. Also available is the Ei170RF kit which includes a vibrating pillow pad as well as the Ei171 xenon strobe.
