GENERAL
The J54 is a compact sprinkler switch designed to actuate
alarms in either wet or dry pipe sprinkler systems. The J54A
is a dual switch version of the J54.
The pressure switches are intended for either alarm or super-
visory service. Each consists of a diaphragm pressure cap-
sule connected to a plunger which moves in response to
pressure changes, operating a snap switch for signal initia-
tion.
