In occupancies required to be equipped with a fire alarm system, theback-flowpreventer valves shall be electrically supervised by a tamper switch installed in accordance with NFPA 72 and separately annunciated.
First you locate the source of the alarm, undo the condition (e.g., valve closed, inadequate pressure, etc), then reset the alarm condition on the sprinkler control panel and reset the alarm on the fire alarm control panel (assuming they're connected, as required by many fire codes).
The Tamper switches for a fire sprinkler system are located on the main control valves which are located on either side of the backflow preventer for a wet type automatic fire sprinkler system. These switches are wired into the monitoring control system/alarm panel to ensure the valves remain open at all times (or not tampered with.) If the tamper switches are used they will show a supervisory trouble on the panel so the monitoring company or business will know there system is out of service.
The function of a water flow switch is to detect water flow in the sprinkler system, usually during a fire event, to signal a local electrical fire alarm, or fire alarm panel to activate the alarm devices in the building,and send an alarm signal to a central station or alarm company to alert the fire department.
