The Tyco® QRS-2 Quick Release Switch helps reduce valve operating time and false trip issues that often occur with traditional mechanical accelerators. Operation of Tyco DPV-1 dry pipe or DV-5A preaction valve within four seconds Ideal to retrofit existing mechanical accelerators where a releasing panel is already installed UL Listed and FM Approved Reduce Water Delivery Times The QRS-2 is a quick-opening device intended to reduce the operating time of a dry pipe valve in a dry pipe system or an automatic control valve (deluge valve) in a double-interlock electric/electric preaction system. The QRS-2 electronic dry pipe accelerator automatically adjusts to both small and slow changes in system pressure, but it trips with a steady drop in pressure. Features Operation of Tyco DPV-1 dry pipe or DV-5A preaction valve within four seconds Ideal to retrofit existing mechanical accelerators where a releasing panel is already installed UL Listed and FM Approved Proven electric release technology as used for electrically operated deluge and preaction systems Control up to two QRS-2 switches on one to two system risers (Tyco Model DPV-1 Valve with AutoPulse Z-10 or AutoPulse Z-20 Releasing Panel) Control up to four QRS-2 switches on one to four system risers (Tyco Model DPV-1 Valve with Potter PFC-4410G3 or PFC-4410RC releasing panel) Built-in low and high pressure alarm supervision Integrated indicator light shows system status Benefits Faster Trip Time Deliver water sooner with a quicker, more consistent trip time compared to a mechanical accelerator.
