Alarm Relays
The SPST 24V 500mA relay contacts are normally open and
will close on alarm conditions when the alarms are enabled.
Relay contacts are always functional when the alarm is
enabled. The relay will close only during minimum and
maximum alarm conditions. Two pen models have 2 sets
of relay contacts which operate independently. Relays will
not operate under battery only power conditions.
