College, university building fire/life safety design
College and university campus buildings have a lot going on—classes, research, dining, and sleeping. Fire, life safety, mass notification, and emergency communication systems are key components of these campuses.

CSE: What unique fire suppression systems have you specified in these facilities?
Hassler: For a recent project we used a wet pipe pre-action to reduce the damage that accidental water damage would cause without the issues associated with corrosion of a dry pipe system or nitrogen charges. This system can be applicable for locations where some water discharge is not catastrophic. A broken sprinkler head may discharge many gallons of water, but it is significantly less compared to a sprinkler head discharging 15+ gpm for 15 minutes or longer until it can be shut off.
