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.
