Description

The Model 4200 Displacement Detector System is an _Early Warning Systemî. The displacement detector consists of up to 6 displacement sensor switches. The detector control unit is attached to a post. The sensors switch ends are mounted on stable ground and the other end is attached and turns on a audible / visual alarm to the moving section. The system switches when a pre-set displacement is exceeded or the cable is broken. The Model 4200 controller allows up to six sensors to be monitored continually.
