Global Cache 950-0009 Contact Closure Sensor

Quick, dependable contact sensing streamlines security and automation workflows. The Global Cache GC-SC1 Contact Closure Sensor detects the open/closed state of isolated contacts—ideal for door strikes, drapery controllers, thermostats and other security or monitoring points. Designed as a media/logic interface, the GC-SC1 plugs directly into the Global Cache GC-100 network adapter or any controller that supplies 5V and accepts TTL input, making networked contact monitoring simple and reliable. Its onboard debounce circuitry filters contact bounce, reducing false alarms and unnecessary maintenance calls, while the fast-close/slow-open response delivers both prompt event detection and stable state reporting. The unit uses a standard 3.5mm stereo jack for quick wiring and a compact, black enclosure that fits discreetly in control panels. Backed by a 2-year limited warranty, the GC-SC1 provides a cost-effective, professional-grade solution for security integrators, AV installers, and building automation teams. Add the GC-SC1 to your surveillance or access control system to improve monitoring accuracy and reduce downtime.
