  • NITROGEN-PAC SC Series Is Now Factory Mutual (FM) Approved – UNITED Fire Systems is proud to announce that our NITROGEN-PAC SC Series sprinkler corrosion inhibiting systems are FM Approved! The NITROGEN-PAC SC Series is a family of FM Approved nitrogen-based sprinkler corrosion inhibiting systems, providing high-purity dry nitrogen for the interior of preaction and dry sprinkler piping. These units feature a compressor for system initial fill and nitrogen generation, refrigerated drying of the air for the lowest possible moisture content, and membrane technology for efficient nitrogen generation. The SC Series factory-assembled units save space and shorten installation and commissioning time. Click here to learn more…

  • Air Release for Wet Sprinkler Systems (AR-1) is Now Factory Mutual (FM) Approved – UNITED Fire Systems is proud to announce that our Model AR-1 Wet Sprinkler System Air Release Device for wet sprinkler systems is now FM Approved! This device is now required by NFPA Standard 13 on all new wet fire sprinkler systems. The device releases the air from the high point(s) of the system, but prevents water from coming out of the device. Eliminating the air pockets reduces internal pipe corrosion and lengthens the life of the system. An updated Data Sheet and Instruction Sheet for the AR-1 have both been released and are now available to download. Click here to learn more…

Technical Notes from UNITED Fire Systems

  1. April 2018 – Technical Note UFS-18-02B – We have also experienced numerous instances of electricians trying to wire additional horn strobes to our Boston-version STANDPIPE-PACS, and missing things or causing damage that requires a service call. What we have come to realize is that most of the electricians performing this work have limited low-voltage experience, and may never have worked on fire alarm before. Technical Note UFS-18-02B has been created to address these issues and provides step-by-step instructions that can help electricians perform this work properly. Click here to learn more…

  3. January 2018 – Technical Note UFS-18-01 – Last month, we issued Technical Note UFS-17-07 regarding operation of STANDPIPE-PAC in cold weather.

Technical Note UFS-18-01 provides information for installers and inspectors to make sure a main drain is installed and used on the dry standpipe, and also information on setting up a condensate drain near the STANDPIPE-PAC outlet.

Did You Know?

  • If you have a dry standpipe in your structure, can you tell if it’s intact and ready for fire department use? If it’s not, the risk is high.  Be sure – a UNITED Fire Systems STANDPIPE-PAC system will alert you if someone accidentally leaves a valve open or even disassembles a portion of the standpipe inadvertently.
