QRS-2 Quick Release Switch

Electronic accelerator for dry pipe or preaction sprinkler systems

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.
Reduce Water Delivery Times

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
Faster Trip Time

Deliver water sooner with a quicker, more consistent trip time compared to a mechanical accelerator.

Reduce False Trips
Reduce False Trips

Active air pressure monitoring adjusts to small and slow changes in pressure system, but trips when there is a steady pressure drop.

Easy Resetting
Easy Resetting

Electronic reset eliminates the complicated breakdown, overhaul, and reassembly of a mechanical accelerator.
