Alarm Relays:
There are three alarm-circuit connectors on the alarm relays block
(under RELAY OUTPUTS) for making connections to internal alarm relay
contacts. Each provides a set of Form C contacts for each type of alarm.
Each has both normally open and normally closed contact connections. The
contact connections are indicated by diagrams on the rear panel. They are
capable of switching up to 3 ampers at 250 V AC into a resistive load
(Figure 2-6).
The connectors are:

• Can be configured as high (actuates when
