A large manufacturing facility frequently re-arranges the interior layout of their plant for efficiency reasons. As a result of the changes, they regularly disassembled and relocated tornado and fire warning sirens. When the warning system was “hard-wired”, the job was expensive and time consuming. By utilizing our wireless technology and plug-in power connections, the customer now relocates the receivers and sirens quickly and efficiently. Time, material and dollars saved. The image shows both the receiver and transmitter.
