Operation
The Bell Alarm–Alarm Only provides normally open (NO)
and normally closed (NC) outputs available at the
terminal block on the right side of the switch, as
illustrated in Figure 12. The outputs change state
whenever a switch ground fault trip occurs. This trip can
be caused by a ground fault condition detected by the
Control Unit.
The Bell Alarm–Alarm Only accessory resets automatically,
returning the outputs to their normal configuration, when
the switch is reclosed. The Bell Alarm–Alarm Only can
also be reset manually, before the switch is reclosed, by
pressing the reset button on the front of the module.

terminal block. The contacts are shown in the reset state.
3-4 Bell Alarm with Lockout
The Bell Alarm with Lockout module, shown in Figure 13,
prevents reclosing of the switch after a ground fault trip
until the Bell Alarm with Lockout is reset. It can only be
reset by pressing the button on the top of the module.
This module also provides a switch to remotely indicate
that the switch has tripped.
The Power+™ Control Unit activates the Bell Alarm with
Lockout for ground fault protection trips only.
The catalog numbers for the Bell Alarm with Lockout are
listed in Table 10. For installation instructions see GEH–
