Relay Operation
Relays 1 and 2 have standard functionality as defined below.
Relay 1 Operation
Relay 1 enters alarm state when there is a new alarm. This
relay will clear when the alarm is acknowledged, generally by
pressing the
ACK
pushbutton.
Relay 2 Operation
Relay 2 enters alarm state when any channel displays in alarm
state. This relay will clear when all indication LEDs are cleared.
Relay Fail-Safe
In fail-safe operation, a relay coil is energized in non-alarm
condition. In case of power failure, relays will go to alarm state.
Fail-safe operation is set independently for each relay.
