Fire alarm panel & velux kf120

[tazz]

If theres fire doors as my previous, I can see what BC/FO are after Harni......staircase zoned as usually, any fire, he want smoke unhindered by other vents straight up and out, if lobby or corridor off staircase, all extract doors & top of shaft to open unhindered aswell....spread of fire from one the the other opens all/next.

Hi harni
normally we would use our fire panel linked to relay in the AOV so it activates the AOV on any signal.
Then just how I operate the fire doors, but I suspect they should open all together but if they want them independent then I will try to make it work

Yeah i can see what it is that he wants to do. Makes complete sense but i think the issue is going to be opening each door individually. E.g fire on floor 1, only door on floor 1 opens into the shaft. It depends on the Velux controller (which if I've understood correctly, also controls these doors?) and if it can open individual doors.

Hi harni
what about velux opening under any fault on fire alarm panel & using 3 zone panel then use each floor as a zone & each door activated of whatever zone would that work.
