fire alarm for a multiple building

[danny7299]

there are 4 building's all needed to have a fire alarm , 3 store buildings and a showroom, ... can you each buiding have there own fire alarm, and then be tied into the main showroom system?

if so how would you do this?

Cheers

Danny yes

All 3 store buildings are stand alone with hard wire or radio link to the showroom building panel.

Depends how close to each building and are there link corridors.Again without the full details 1 could be 3 miles away, are they all on the same site.

there are ducts between them and there about 10m between each building.... what kind of pannel would i need?

most panels have a volt free relay - this can be used to activate a communal panel

 

[danny7299]

and then do you just put that into the zone input... ?

If there is only 10 metres of ducting between the buildings, depending on what the customer wants you would have to wire each building in 3 two cores back to the No 1 building in fire tuf with a four zone panel.probaly the cheaper option 2 sounder circuits and one detection.

This is all relevant on the size of the storerooms what type of protection required.

Or seperate single zone panels and you use the outputs to a panel in the main building as a Zone again 4 Zone panel required.Complications on trying to reset unless you use a other funcion i.r. class change.

Recommend you cantact a major alarm company for a quote they will give you in writeng what you want, act a agent for the customer and copy specification.Remeber it will not be a design document.

This reminds me of an embarrassing incident for some fire alarm 'engineers' a few years ago. They wired the Aux contacts from each outbuilding alarm to the main panel in the security room. The main panel also triggered each panel via a zone labeled as 'fire alert on site, next building'. The problem was they couldn't turn it off. As a panel triggered the main, this sent back the fire alarm in next building, and this just cycled and cycled. They had to get 6 guys all to press the silence buttons in the different buildings at the same time.

Happens all the time when you let the young ones do the programming. no harm done they have to run around, good learning.

Worse thing is when it shuts of plant/ gas valves whata no lunch.
