Simplex abort and maintenance switches provide a clear and secure means to request manual abort of fire suppression release and to disconnect releasing appliance circuits during maintenance.
Abort switches use a momentary pushbutton with protective collar, while maintenance switches use a maintained-position keyswitch, with flush or surface mounting options, making them suitable for releasing systems that require clear and safe control according to life-safety requirements.
Releasing systems often require clearly labeled abort and maintenance disconnect switches that are easy to operate and rugged enough for critical life-safety applications.
Abort switches provide a manual release abort request through a momentary pushbutton mounted on a stainless steel single-gang plate, with a protruding collar that protects the switch from accidental contact, and flush or surface mounting options.
Maintenance switches provide a secure and visible disconnect means for Releasing Appliance Circuits (RACs). The disabled position opens the connection to the output circuit and places a resistor across the input circuit to initiate a supervisory condition at the host panel.
Models are available with or without indicator lamps, with stainless steel plates and flush or surface mounting according to configuration, supporting different operating and maintenance requirements.
By combining clear labeling, protection against accidental operation, secure maintenance disconnect, and flexible mounting, these switches help releasing systems operate more safely and clearly.
