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 3-4. They are
capable of switching up to 3 amperes at 250 VAC 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 non-latching
Can be configured out (defeated).
