VENTILATION FANS XFN0200 ANO XFN0202 OPERATE AT ALL TIMES.IF A LOSS OF FLOW IS DETECTED AN ALARM IS GENERATED AND ADDITIONAL FANS ARE STARTED AUTOMATICALLY.

XFN0204 STARTS AUTOMATICALLY WHEN XEG0103 rs STARTED.XFN0203 AND XFN0205 WILL START AUTOMATICALLY IF DG ROOM TEMPERATURE INCREASES 1

ABOVE 80 DEG F ANO OG IS RUNNING.XFN0203 AND XFN0205 WILL SECURE IF ROOM TEMPERATURE DROPS BELOW 60 DEG F.

C.

HVAC ALARMS ARE INDICATED ON XPN5387.GENERAL 'EB HVAC TROUBLE ALARM" IS INDICATED ON TEMP MONITORING SYSTEM AND ANNUNCIATED IN MAIN CONTROL ROOM.
