SD1 & TSD2

A speech dialler is a device that will automatically contact specific people, either via phone call or text message, when a system is activated, providing the ability to be notified of events such as a burglary or fire, as they happen.
The SD1 and TSD2 are stand-alone speech diallers designed to complement any system that requires alerts of changes in system conditions. The TSD2 is also capable of temperature monitoring.
