PRESS RELEASE
MILWAUKEE — Johnson Controls, the global leader for smart, healthy and sustainable buildings, announces the new Tyco QRS-2 Quick Release Switch, an electronic accelerator that improves response time of Tyco dry pipe and preaction valves within fire sprinkler systems. The QRS-2 switch uses proven electric release technology to initiate operation of valves within four seconds after sprinkler activation. An increased valve response time means water is released more quickly through the pipes and to the fire hazard.
Using built-in low- and high-pressure alarm supervision, the QRS-2 Quick Release Switch automatically adjusts to small and slow changes in system pressure by sampling air pressure three times per second. When the device records a steady drop in pressure, as in the case of sprinkler system operation, it sends a signal to release the valve. Electric release technology helps reduce accelerator operating time and false trip issues that often occur with traditional mechanical switches.
“The QRS-2 is built on the same proven, trusted electric release technology behind the Tyco electrically operated deluge and preaction systems our customers know and trust,” said Beth Bjorlo, product management director, Fire Suppression Products, Johnson Controls. “This new switch will increase the confidence of customers, since they’ll know their fire suppression system is optimized for quick response to hazards.”
The QRS-2 Quick Release Switch can be used with Tyco DPV-1 dry pipe valves and DV-5A automatic control valves and is an integral part of the Tyco QUELL cold storage fire protection system. Its unique design gives it the ability to control up to two QRS-2 switches on one to two system risers, or up to four QRS-2 switches on one to four system risers, depending on the specific riser and releasing panel combination.
The QRS-2 Quick Release Switch comes fully assembled with battery backup in case of primary power failure. The device is UL Listed and FM Approved.
