The Trouble terminals are dry form C relay contacts. They activate on any module-related trouble and clear
when all troubles are clear.
NOTE
These terminals are in the trouble state when all power is removed.
1st Stage
The 1st Stage terminals are normally-open relay contacts. They activate when the first pre-release condition
has been met. The first pre-release condition is satisfied upon activation of any initiating device in any of the
zones associated with this releasing control.
2nd Stage
The 2nd Stage terminals are normally-open relay contacts. They activate when all pre-release conditions have
been met and the release delay countdown has started.
If the
Activation Mode
setting in the XT+ Module configuration is set to "Single", the 2nd Stage activates
simultaneously with 1st Stage.
If the
Activation Mode
setting in the XT+ Module configuration is set to "Coincidence", the 2nd Stage activates
upon activation of a second initiating device in any of the zones associated with this releasing control.
3rd Stage (Released)
The Released terminals are normally-open relay contacts. They activate when the release delay countdown
has completed and the extinguishant is being released.
Supv. / Abort
The Supv terminals are normally-open relay contacts. They activate on any module-related supervisory
(depending on configuration) and clear when all supervisories are clear.
