Valve maintenance kit AMD-1

The TYCO Model AMD-1 Automatic Air Maintenance Device is an automatic, field-adjustable, pressure reducing device. It is used to control the pressure in a dry pipe sprinkler system, preaction system, or dry pilot line system of a dry pilot actuated deluge or preaction valve. The Model AMD-1 Device is utilized in applications where there is a compressed air (or nitrogen) source controlled at a higher pressure than the desired system pressure. Pressure sources include plant air supplies with their own automatic compressor controls or nitrogen supplies with singlestage, cylinder-mounted pressure regulators. The Model AMD-1 Automatic Air Maintenance Device is a re-designation for the Central Model D-2, Gem Model F324, and Star Model S460. The Model AMD-1 Automatic Air Maintenance Devices described herein must be installed and maintained in compliance with this document and with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION, in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices. Owners are responsible for maintaining their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.
