AND gate and panel restarting

Post by ashudwd16 »

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.

the translation is bad

one problem at a time.
it sounds like panels 2,3 and 4 restart when you get the second alarm on panel 1 and the deluge activates
so what would or how could a EST3 panel do a restart when another panel has an alarm.
that is the question to answer.

how are you routing the alarms.
is the output causing this
if two different devices go into alarm from panel 1 (not part of the deluge) do the panels restart.
if you remove the deluge rule do the panels restart
-- call me after you check these things
