【点検マニュアル】予作動スプリンクラーの点検マスターになろう‼️ #消防設備点検 #消火設備

We've created an inspection manual for pre-action sprinklers, which are relatively rare among sprinklers! This video mainly explains Senju Sprinkler's pre-action sprinklers, so there may be some differences depending on the manufacturer and local specifications. The principle is the same, so if you watch this video, you should be able to inspect a pre-action sprinkler! #FireEquipmentInspection #Sprinkler
