Silent Call Communications Wireless Alerting Systems
Silent Call wireless alerting systems allow a deaf or deaf/blind user to be discreetly alerted to the activation of any one of a number of common household devices such as a doorbell, telephone ringer, smoke detector, sound monitor, door or window activity, etc.
We have first listed, below, a few kits, which contain one or more transmitters and a body worn receiver. There is no limit to the number of receivers and/or transmitters that can be added to an existing kit. These kits (our product numbers HI-GV-KIT-6D, HI-VC-KIT-6D and HI-VC-KIT-6) are assembled from the original Silent Call Alerting Systems which operate at 318MHz and the maximum distance between transmitters and a receiver is typically 200 feet.
The various original Silent Call Alerting receivers and then transmitters are listed below the kits and can be combined as desired.
Finally we have listed the new longer distance Silent Call Signature Series Alerting Systems. The Signature Series operates on the all new 418MHz transmitting frequencies and there are various receivers and transmitters. This Signature Series has up to a 2,000 foot range from transmitter to receiver.
