External Device Connection Application
Fig. 5 shows an external device connection application. External
devices chain EXIST relay(s) and NEW relay(s) together after
alarms or acknowledgment.
If the EXIST relay drops, its contacts open and the closed NEW
relay contact does not signal the external device. If the NEW
relay drops, the EXIST relay does not signal the external device.
The built-in audible device continues operating until it times out
or it acknowledges the alarms.
