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. They are capable of switching up to 3 amperes at 250 V ac into a
resistive load. The connectors are:
Threshold Alarm 1:
Can be configured as high (actuates when concentration
•
is above threshold), or low (actuates when concentration
is below threshold).
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 concentration
•
is above threshold), or low (actuates when concentration
is below threshold).
Can be configured as failsafe or non-failsafe.
•
Can be configured as latching or non-latching.
