QRS Electronic Dry Pipe Accelerator

Description

This electronic accelerator 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 electronic dry pipe accelerator automatically adjusts to both small and slow changes in system pressure, but it trips with a steady drop in pressure. This device comes fully assembled and has a battery backup in case of primary power failure.

Specification

Quick release switch for dry pipe or preaction systems

The Tyco® QRS electronic dry pipe accelerator helps reduce accelerator operating time and false trip issues that often occur with traditional mechanical accelerators.

Operation of the dry pipe or preaction valve within four seconds — independent of various combinations of system initial air pressures, system volumes, or sprinkler K-factors
Can be used to retrofit existing mechanical accelerators
Helps reduce false trips typically experienced with mechanical accelerators
