Thanks

The simple answer is no. Wet, dry, and deluge systems can be installed without interface and still be functional. These systems utilize a water driven bell, or water gong, located on an exterior wall. A sign will usually advise anyone who hears the gong to notify the fire department.
In reality, when water flows, owing to the fusing of a head, someone should be notified. In addition, valves are provided for system maintenance, and must not be left in a closed position, or the system will not function as designed. Flow switches, pressure switches, and tamper switches achieve these supervisory purposes. The various switches interface with a control unit which also contains a digital communicator to deliver data to the central station via telephone lines or other communication route.
Most authorities having jurisdiction require sprinkler systems to be monitored by a central station. The station will, upon receipt of a flow, tamper, or trouble code, take appropriate action by advising the fire department, building maintenance personnel and/or the alarm company representatives.
