Magnetic Switches & Tattletale® Annunciators
Tattletale® annunciators and magnetic switches are the nerve centers that translate Swichgage® contact operations into decisions and operate the alarm or shutdown device. These switches are the electrical load carrying devices for the alarm or shutdown device. Tattletale annunciators indicate which monitored function failed leading to the alarm or shutdown. Magnetic switches do not because they operate as a latching relay.
Various circuits, time delays and contact configurations are available to match the power source and mode of operation required for alarm only, alarm before shutdown or shutdown only. Models are available to operate from battery power, 120 VAC, conventional magnetos and capacitor discharge type ignitions. All models have a weather-resistant case with screw terminals for ease of customer hookup.
Energized-to-run models allow Closed Loop circuitry. Others draw momentary power to trip. Configurations are available for contact make or contact break to cause shutdown. Some models have both make and break contacts.
