The Link Electronics PCA-819 is an audible alarm system designed to work with the PCO-818 automatic change-over system. When the change-over is activated because of a loss of master sync the PCA-819 senses the action and offers an audible alarm and an LED readout.
Isolated relay contacts, both normally open, and normally closed, are provided so the user can control other equipment or alarms in the event of a loss of signal at the Changeover Frame.
Bi-color LED's indicate an RED alarm condition , GREEN condition OK, and BLINKING GREEN unit has been disabled.
