Wireless Solutions

SymTech offers the ultimate in wireless solutions. Our lightweight, waterproof wireless transmitters can be worn around the neck as a small pendant, a wristwatch or key chain. Your patients or residents can make an emergency call for help from any location within the coverage area. When the transmitter is pressed, an alarm is sent to a central monitoring system or to pocket pagers carried by staff.

Sentry Freedom wireless receivers and transmitters, engineered by Heritage MedCall, can be added to your system at any time – as original equipment or as a replacement for standard emergency call stations.  Integrating the best available technology, Sentry Freedom has been a reliable, cost-effective solution for the senior market since 1989.

Sentry Freedom includes the same great features that its hardwired system provides, with the added benefits of a wireless solution. Heritage Medcall, when developing Sentry Freedom, integrated the best available technology –  Inovoncis EchoStream 900 MHz spread spectrum technology as the backbone of the wireless system along with Dell Computer for the master console.
