Alarm Relay and Addressable Contact Closures
The rear panel has an alarm relay and two solid-state contact closures addressable from the
™ uplink computer. This relay’s “alarm” conditions are the same as the front-panel
ALARM LED. The alarm relay is factory-set so that an alarm condition or the loss of unit power
will cause the rear panel alarm outputs to short together (alarm relay closed). Ratings for the
alarm relay and network-controlled closures are 100 mA at 30 VDC.
The two contact closures are controlled via the
command stream from the uplink.
See the COMPEL™ Manual for the commands and structure for the relay closures.
