Description
The Model PSTA is a system trouble alarm that is designed to monitor supervisory conditions on fire sprinkler components where a fire alarm is not present or if an additional localized annunciator is desirable. The system has specific applications on dry pipe sprinkler systems to monitor low and high air pressure and low room temperature on the dry pipe sprinkler riser. The PSTA also can be used to provide notification of the operation of Potter's PAAR (Potter Automatic Air Release). The unit consists of a micro-processor based annunciator with an LED system status monitor, an internal buzzer and a set of S.P.D.T. dry relay contacts that may be used for remote annunciation.
