Description
The SUREcom system (formerly ET92A) is a low-cost solution that allows communication from the machine room and/or lobby to the elevator emergency phones, and provides emergency personnel the ability to override a call that is in progress.
Communicate with up to 6 of our AC-powered 901 series emergency phones on a single incoming phone line. When the emergency phones require dedicated phone lines, you can link up to 4 control boxes.
The ET92C is a stand-alone control box. The ET92C-1 includes the control box and a 1-Line handset, and the ET92C-2 includes the control box and a 2-line handset.
