Signaling contact

The signaling contact is an event-driven or manually controlled failsafe alarm relay. Individual
alarms can be configured to trigger the relay when the associated event occurs. The relay can
also be fixed in an open or closed state.
Manually controlling the relay may be useful to:
• Verify the failsafe relay is properly connected following the installation of the device
• Verify the open/close state is caused by the device itself or some other hardware
• Keep the relay in an open/close state while troubleshooting a network issue
