Tattletale® Annunciators and Magnetic Switches

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. Magnetic switches operate basically as a latching relay.

NOTES:
The information above indicates features/configurations available for each model.

1. Coil Voltage - Coils are specific voltage rated or multiple voltage rated.
2. Contacts - This is the control circuit output. In the lathed position the NCH contact has a "hot" output. In the latched position, the NCG has a "grounded" output; in the tripped position, the NOG has a "grounded" output.
3. Latch Type - Refers to whether the magnetic coil is momentraily energized to trip or requires continuous power in the operating mode and de-energizes to trip.
4. Reset Type - Refers to manual or electric reset; manual indicating type is a TATTLETALE.
5. Time Delay - Indicates operation of the time delay.
