The ERS1 wired sensor is designed to protect window and door roller shutters from intrusion or burglary. It is triggered by a set value of impulses when someone tries to physically open, close or damage window or door protection roller shutters.
For proper system operation one ERS1 sensor must be connected to the wired input of one EWD3 wireless magnetic contact sensor. The ERS1 is equipped with a high-speed sensor mechanism that detects any intrusion or sabotage eliminating the possibility of false alarms. In addition you can quickly and easily change the pulse counter settings using the ELDES Utility configuration software.
