Boston FD TCM3-51725 was implemented in response to serious difficulties encountered when fire standpipes at construction and demolition sites were damaged, rendering the standpipes unsuitable for fire department use. The directive 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 directive. STANDPIPE-PAC™ has been designed to aid in compliance with the requirements in Boston FD TCM3-51725.
IMPORTANT: Boston FD TCM3-51725 requires that an application to install an air pressurized alarm system be filed by a registered design professional, and a permit obtained by a licensed sprinkler contractor. A licensed electrician shall obtain all required electrical permits. Install STANDPIPE-PAC™ after application is made and accepted, and all permits received.

Your dry-pipe or preaction system piping may look brand new on the outside, but what about inside? Residual water and oxygen in the pressurized air could be rusting the interior of that pipe right now. This rust can weaken the pipe, cause pinholes to form, and even clog up the sprinkler heads in the event of a fire. NFPA 25 – Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems mandates internal inspection of sprinkler pipes at least every 5 years. Are your pipes rusty? Have them internally inspected by a qualified fire protection contractor before it’s too late.
