The EV-1 is the perfect solution to help make your elevator/emergency phone A.D.A. compliant.
The EV-1 is a line powered emergency voice announcer designed to add a natural voice announcement to any telephone. The announcer provides ten seconds of non-volatile record time that can be used to communicate the location of an emergency phone, or a piece of malfunctioning equipment.
After a call initiated behind the EV-1 is answered, the EV-1 repeats the announcement continuously. Emergency personnel can stop and start the announcement at will by dialing a Touch Tone *.
