Alarm Relays: The nine alarm-circuit connector pins connect to
the internal alarm relay contacts. Each set of three pins provides one set
of Form C relay contacts. Each relay has both normally open and
normally closed contact connections. The contact connections are shown
in Table 3-2. Contacts can switch up to 1 amp at 250 V ac into a
resistive load. The connectors are:
Threshold Alarm 1:
• Can be configured as high (actuates when
• Can be configured as failsafe or non-failsafe.
• Can be configured as latching or non-latching.
• Can be configured out (defeated).
Threshold Alarm 2:
• Can be configured as high (actuates when
• Can be configured as failsafe or non-failsafe.
• Can be configured as latching or non-latching.
• Can be configured out (defeated).
