How do office buildings test whether their sprinkler systems work?
In: Engineering
When the sprinkler system is designed/ installed, there is an inspectors test valve. The system is tested by opening a valve to create flowing water in the system without opening a sprinkler head. This is to ensure the alarms will activate properly, and the inspectors can check pressure.
The individual heads are not tested once installed, for obvious reasons. Instead the heads are tested at the manufacturer with a random sampling of a production lot. Routine inspection of the heads, especially in dirty environments make sure the head isn’t caked with dust, grime, paint, etc. which would hinder activation.
