AND gate and panel restarting
Posted: Fri Oct 13, 2017 9:04 am
Dear Sir,
In our project we have total 4 EST3 panel which are communicating to each other through multimode fiber cable.
Distance among the panels are P1 to P2- 1500M.
P2 to P3 - 1200M.
P3 to P4 - 700M.
As per writeup, when min. 2 Nos. detector operate in cable gallery then deluge valve should be activated and alarm goes to in that panel and also in P4. But we are facing problem is there, when we operateonly 1 detector then alarm is going in that panel and P4 also but when we operate 2 Nos. detectors at a time then Deluge valve operates and get alarm in that panel. other 3 panels (P2,P3,P4) are getting restart at same time and after that we get alarm in P4 Panel.
Please resolve problem earliest and provide solutions.
