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.
Benefits
Faster Trip Time
Deliver water sooner with a quicker, more consistent trip time compared to a mechanical accelerator.
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
Electronic reset eliminates the complicated breakdown, overhaul, and reassembly of a mechanical accelerator.
