QRS-2 Quick Release Switch

Improve Response Time for Dry Pipe and Preaction Valves

The new Tyco® QRS-2 Quick Release Switch improves response time of Tyco dry pipe and preaction valves within fire sprinkler systems. This electronic accelerator 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.

Features and benefits include:

• Operation of dry pipe and preaction valve within four seconds
• Built-in low and high pressure alarm supervision
• Use with Tyco DPV-1 dry pipe valves and DV-5A automatic control valves
• Integral part of the Tyco QUELL cold storage fire protection system
• UL Listed and FM Approved
