Global Caché
GC-SC1
Contact Closure Sensor
The Global Caché GC-SC1 is a contact closure sensor. Its circuitry provides a
rapid response to contact closure (4mS typ) with a slow response to contact opens
(75mS typ). This eliminates false triggers due to contact bounce created by
mechanical contacts coming together, such as push buttons or relays. The
following illustrates a typical push button installation along with the GC-SC1
response.

The GC-SC1 plugs directly into the GC-100 Network Adapter’s IR/Sensor
connector for proper operation. (The GC-100 connector must be configured as
an input. See the
GC-100 Quick Start
for more information.) The GC-SC1 is
connected directly across the contacts, with the open/close state to be determined.
There is no polarity to the wiring. Below is a typical installation using the GC-
SC1.
