General
The Reliable Model B1 Accelerator with its integral Ac-
celo-Check (anti-flooding device) is used to speed up the
operation of both dry pipe valves (in dry-type automatic
sprinkler systems) and deluge valves (in pre-action sprin-
kler systems). Both of these system types utilize pressur-
ized air, instead of water, in their piping as to avoid expo-
sure to water sensitive areas and/or freezing conditions.
The accelerated operation of the dry pipe valve floods
the sprinkler system with water permitting a substantial in-
crease in both the number of sprinklers that can be con-
trolled by one dry pipe valve and the volume of the dry
system that can be installed.
