Using Transferred Normal / Emergency
(Generator) Circuits with SIMPLY5
A SIMPLY5 S5JS Joiner Splice can be
used to isolate one or more fixtures in
a room from the normal power circuit
and feed those fixtures instead from an
alternate source, such as a transferred
Normal / Emergency circuit. If the S5JS is
used to feed normal/emergency fixtures
with transferred power, then the S5JB
must be fed from a normal power circuit.
The SIMPLY5 ballast will automatically
switch the lamps to full intensity and the
wallstations will be disabled whenever
the S5JB is not powered (normal power
is lost). A functional wiring diagram of
a simple system with both normal and
normal/emergency circuits connected
with a S5JS Joiner Splice is shown in
Diagram 1, above, and an example room
with two normal/emergency fixtures for
egress lighting is shown in Diagram 2.

In this example, when the room is
normally powered all fixtures are
controlled together from either of the
wall stations. When normal power is
lost, the emergency fixtures will turn on
to 100% as soon as they are powered.
Any room controls (wall stations in this
case) will be disabled as long as normal
power is lost. When normal power is
restored, the egress lighting fixtures will
be returned to the level at which they
were set before the interruption.

SIMPLY5 ballasts are controlled with a
digital signal and do not require that the
power feeding them be switched on and
off like a conventional ballast. Because of
this, SIMPLY5 light fixtures are typically
fed with a constantly powered circuit.

When a Power Sentry® Battery Pack
is also installed in a light fixture, it then
can be connected to the same hot and
neutral that normally powers the fixture.
Because the circuit is unswitched, it can
simultaneously power the fixture for
normal use, charge the battery pack,
and act as normal power source for
the battery pack lamp transfer circuit.
Diagram 1, above, is a simple functional
wiring diagram showing how the S5JB
Intelligent Junction box, SIMPLY5 ballast,
and Power Sentry emergency battery
pack are connected, and Diagram 2
shows a typical room layout using fixtures
with battery packs for egress lighting. In
the standard SIMPLY5 configuration, all
wiring shown in Diagram 1 would be
contained in the Reloc modular wiring.
