ADA 121® Audio Visual Alert System
The ADA 121® is a modular device which enables people with visual and/or hearing impairments to be made aware of incoming telephone calls and/or when visitors to their residence are outside their front door and ringing the doorbell.
Resident awareness is stimulated via a very loud piezoelectric buzzer and a flashing strobe light. The length of the sound emitted and the strobe flashing may be adjusted from 1-60 seconds and can be RESET anytime in between.
The ADA 121® is designed to work with existing residential or building access control systems including: doorbell, intercom, telephone entry, and emergency call systems; as well as the standard telephone system (POTS).
