Tyco Fire & Building Products Creates a Safer Means of Freezer Fire Protection

Lansdale, Penn.-September 2, 2004-Tyco Fire & Building Products, a business unit of Tyco Engineered Products & Services, recently announced the introduction of its DSB-1 dry sprinkler boot to the dry pipe fire sprinkler market. The DSB-1 will combat the potentially damaging temperature changes that can adversely affect dry sprinklers installed in freezers. Tyco Fire & Building Products' DSB-1 dry sprinkler boot is an EPDM, 50 durometer-type rubber boot designed for installation with all vertical, or pendent, dry sprinklers. Once installed, the boot creates an airtight seal, eliminating the build up of potentially dangerous condensation by maintaining consistent temperatures both outside and within the freezer area. Dry sprinklers used in freezers are subject to extreme ranges in temperature, from over 40 F in the building that houses the freezer, to temperatures as low as -20 F in the freezer itself. This temperature change, or air interchange, can cause condensation to build-up on the shaft of the sprinkler. Significant ice accumulation can lead to ice build up that can damage the dry sprinkler and the freezer itself. Unlike the traditional foam-seal method of dry pendent installation that relies on insulation or caulking that often breaks, allowing moisture penetration, the DSB-1 provides flexibility and pliability to the sprinkler piping system. This allows the pipes to move without violating the integrity of the seal. The DSB-1 also provides a fast and easy installation as it is installed with the dry sprinkler itself. "In an effort to ease the installation, we are selling the DSB-1 in individual kits that will furnish the installer with the required fastening material for each boot to be installed," says Jim Brunetti, Tyco's Fire Protection product manager. "The product will afford a quick and easy alternative to the old time consuming methods. The seal also provides a very clean manner of sealing the openings for the dry pendent sprinklers." The DSB-1 dry sprinkler boot is a specifiable product that is applicable for any dry pendent sprinkler in a freezer or cooler application. Dry sprinklers and dry pipe sprinkler systems are designed for installation in areas where freezing temperatures may occur such as commercial freezers, loading docks, and parking garages. Unlike the traditional, wet fire sprinkler system; a dry system uses compressed air to fill the pipes supplying the sprinkler heads. Upon activation of one or more sprinklers, the air is released, allowing water controlled by a valve in a heated area to then fill the system and suppress the fire.

Tyco Fire & Building Products will formally introduce the DSB-1 dry sprinkler boot at the upcoming AFSA Convention and Exposition in Palm Springs, Calif., September 11-15, 2004.
