power ventilation.
Nat Auxiliary
would be when the controller has seen an open signal from the natural curtains
during tunnel or that the curtains never closed from natural allowing the system to go into
tunnel. This alarm would take 13 minutes from when it started to go into tunnel. After 20
seconds the system will come out of tunnel and return to natural or power ventilation.
Low Pressure
would be when the pressure fell below the low pressure alarm setting during tunnel.
This alarm will need to see the pressure below the limit for 45 seconds. At this point the
Alarm Status LED will start blinking. Then after another 20 seconds the system will come out
of tunnel and return to natural or power ventilation.
High Pressure
would be when the pressure went above the high limit alarm setting during tunnel.
This alarm will need to see the limit exceeded for 45 seconds. At this point the Alarm Status
LED will start blinking. Then after another 20 seconds the system will come out of tunnel and
return to natural or power ventilation.
