Fig. 18 - - Powered Convenience Outlet Wiring
Duty Cycle
The unit- - powered convenience outlet has a duty cycle
limitation. The transformer is intended to provide power
on an intermittent basis for service tools, lamps, etc; it is
not intended to provide 15- - amps loading for continuous
duty loads (such as electric heaters for overnight use).
Observe a 50% limit on circuit loading above 8- - amps
(i.e., limit loads exceeding 8- - amps to 30 minutes of
operation every hour).
Maintenance
Periodically test the GFCI receptacle by pressing the
TEST button on the face of the receptacle. This should
cause the internal circuit of the receptacle to trip and open
the receptacle. Check for proper grounding wires and
power line phasing if the GFCI receptacle does not trip as
required. Press the RESET button to clear the tripped
condition.
Fuse On Powered Type
The factory fuse is a Bussman "Fusetron" T- - 15,
non- - renewable screw- - in (Edison base) type plug fuse.
Using Unit- -Mounted Convenience Outlets
Units with unit- - mounted convenience outlet circuits will
often require that two disconnects be opened to
de- - energize all power to the unit. Treat all units as
electrically energized until the convenience outlet power
is also checked and de- - energization is confirmed. Observe
National Electrical Code Article 210, Branch Circuits, for
use of convenience outlets.
Smoke detectors are available as factory- - installed options
on 580J models. Smoke detectors may be specified for
Supply Air only or for Return Air without or with
economizer or in combination of Supply Air and Return
Air. Return Air smoke detectors are arranged for vertical
return configurations only. All components necessary for
C08283
operation are factory- - provided and mounted. The unit is

System
H4
H1
The smoke detector system consists of a four- - wire
H2
controller and one or two sensors. Its primary function is
to shut down the rooftop unit in order to prevent smoke
from circulating throughout the building. It is not to be
used as a life saving device.
Controller
The controller includes a controller housing, a printed
circuit board, and a clear plastic cover. (See Fig. 19.) The
controller can be connected to one or two compatible duct
smoke sensors. The clear plastic cover is secured to the
housing with a single captive screw for easy access to the
wiring terminals. The controller has three LEDs (for
Power, Trouble and Alarm) and a manual test/reset button
(on the cover face).
