fire protection of facade
(OP)
I need to ask You for Your opinion in following matter. We are finishing electronics factory building.
We equipped this factory with sprinkler installation (intensity 7,5 mm/m2) connected with internal hydrants system.
Now investor wants us to do drencher (dry, open) installation outside – to protect factory façade. This installation would be electronically steered by control – alarm valve, deluge type.
We need such information:
- What operation area should be assumed
- How many rows of wall drenchers should be mounted (height of building is about 12 meters)
- What water flow rate should be assumed for such installation (and how to determine it)
- Where can we find guidelines to make proper design.
- Can we contact somebody from Your company to consult design in this case
Your answer will be very helpful for us.
Thank You very much,

RE: fire protection of facade
1) What nation is the plant being constructed in?
2) What is the method of construction for the facade?
3) What is the lowest outdoor temperature that can be expected at the facade?
4) What is stored beneath the facade?
RE: fire protection of facade
It is panel wall built of trapeze sheets and mineral wool
Ad 3. We can expect -20degreece of Celsjusz
Ad 4. Nothing will be stored beneath facade.
Investor want this kind of fire protection system because facade wall has to small fire resistance.
RE: fire protection of facade
If the client wants fire protection, I would specify dry pipe sprinkler protection based on a NFPA 13 Ordinary Group I design.
