2-way solenoid valve TFP2180

normally closedfor water

The Solenoid Valves for Releasing Service are intended for use with TYCO Automatic Water Control Valves which are to be electrically actuated and used in deluge or preaction fire protection systems. The Solenoid Valves are used in conjunction with an electric releasing panel that is listed or approved (as appropriate for the authority having jurisdiction) for fire protection releasing service, and where the releasing panel is operated by listed or approved (as appropriate for the authority having jurisdiction) electric fire detectors and/ or initiating devices. The Solenoid Valves described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION (NFPA), in addition to the standards of any other authorities having jurisdiction. Failure to do so may impair the integrity of this device. The owner is responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or product manufacturer with any questions. Operation of an electrical device such as a heat sensitive thermostat, smoke detector, or electric manual pull station signals the releasing panel to energize the releasing circuit. Typically energizing the releasing circuit opens the normally closed de-energized Solenoid Valve to release water pressure from the differential chamber of the Automatic Water Control Valve, which in turn permits the Automatic Water Control Valve to open and allow a flow of water into the system piping.
