Silent Call Signature Series Sound Monitor

The Silent Call Signature Series Sound Monitor may be placed in a room to alert the user to sounds such as a baby's cry, an apartment door buzzer, alarm clock, oven timer, etc. This alerting device is ideal for the deaf and hard of hearing. The Sound Monitor system has a delay circuit so that loud sounds that are very brief (such as a door slamming) will not activate the transmitter. When the sound monitor detects a sound that is above its adjustable detection threshold, the alerting device sends a signal to any Signature Series receiver. (Receiver sold separately.) Operates on 2 AAA batteries (included). 5-year limited warranty.
