NYC Local Law 64 was implemented in response to serious difficulties encountered by the FDNY when fire standpipes at construction and demolition sites were damaged, rendering the standpipes unsuitable for fire department use. The law requires that all fire standpipes in vacant buildings, buildings undergoing demolition, and required permanent or temporary standpipes in buildings under construction be equipped with a system to pressurize the standpipe at all times, which then would sense the pressure loss if a portion of the standpipe was damaged or completely removed. Detailed requirements for the system are specified in the Law. STANDPIPE-PAC™ has been designed to aid in compliance with the requirements in Section 4 of Local Law 64.
IMPORTANT: Section 3 of Local Law 64 requires that an application to install an air pressurized alarm system be filed by a registered design professional, and a permit obtained by a master plumber or licensed master fire protection contractor. A licensed electrician shall obtain all required electrical permits. Install STANDPIPE-PAC™ after application is made and accepted, and all permits received.
Your wet-pipe sprinkler system may not be as filled with water as you expect it to be. A bubble of air may migrate to the highest point in the system, creating a very vulnerable location for internal pipe corrosion. That’s why NFPA 13 now requires that all new wet sprinkler systems be fitted with an air vent at the system’s highest point. This is a good investment for both new and existing systems. The UNITED Fire Systems Model AR-1 automatic air vent device is Factory Mutual (FM) Approved for just this function. See here for more information, and take action to prevent damaging corrosion.
