Alarm Relay Connections (CS700 Only)

Alarm relay connections for the CS700 are provided at the terminal strip on the top of the CPU
rear panel transition card. The customer must provide an appropriate connector or wiring
harness.
The alarm contacts are dry relay contacts configured by default to be normally open, but
●
can be configured to be normally closed with jumpers on the transition cards. See
Contact Configuration" below.
There are two sets of contacts, one for visual alarms (V) and one for audible (A) alarms.
●
Within "visual" and "audible," each set has contacts for Critical, Major and Minor alarms.
●
"Ei1" and "Ei2" are not used.
●
Initially, when an alarm is asserted, both the audible and visual contacts for that alarm will
●
be activated.
If the user presses the Alarm Cut-Off button (ACO) on either the CPU front panel or the
●
transition card panel, the audible alarm contacts will be de-activated.
The visual alarm contact will be de-activated when the alarm condition is cleared.
