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.
