Product Description

Product overview

The pre-action alarm valve group combines the automatic fire detection alarm technology and the automatic sprinkler system to install a closed sprinkler in the system. In the absence of a fire, the system pipes are usually filled with low-pressure air or ammonia gas for detection, so it has the characteristics of a dry system. Therefore, it is suitable for installation in places where water is needed to extinguish fires but never allowed to run water in a fire. For example: libraries, archives, valuables storage rooms, computer rooms, etc. It can also replace dry systems in areas such as high temperature and freezing.
