Auxiliary Output
The auxiliary output enables peripheral equipment (beacons, video cameras, alarms, and so on) to be
activated when the emergency push button is pressed. The auxiliary output is a solid state relay that
optically isolates the control voltage from the output contact. The auxiliary output is disabled when the
emergency push button is depressed.
See Figure 5 and Figure 6 for typical interconnection details of the GAI-Tronics 530A or 530FB Beacon

interconnection details of relays to the auxiliary output. The relay design guidelines, the Auxiliary Output
Electrical Specifications, and the relay design examples have been provided to aid the user in selecting the
