Edwards Signaling 5530MHV - Manual (Page 2)

2 / 7 P/N 3100006 • REV 4 • ISS 09AUG10
6. Torque signal box cover screws to a minimum of 20 in-
lbs.
WARNING: To ensure integrity of the Adaptatone assembly
when adjusting the speaker direction, make sure threads in
the enclosure remain fully engaged and do not turn speaker
more than 360 degrees from the original factory installed
position.
7. To adjust speaker direction, loosen large star nut
(Figure 1) and turn speaker to the approximate desired
position.
8. Regardless of speaker direction adjustment, it is
important that the star nut be tightened wrench tight to
ensure the speaker position is maintained securely.
9. Verify operability.
Wiring
1. Install wires through a knockout hole in the bottom of
the box from a raceway that is, with its connections to
the 1/2" (12.7 mm) conduit knockout hole, approved for
the same degree of protection and enclosure type
needed by the application. Use the provided plastic tie-
wrap, on the barrier to the electronics, to separate
incoming power leads from signal and tone initiating
leads, per NEC (Figure 4).
WARNING: To prevent fire and shock, wire the Adaptatone
only as described in this installation instruction.
2. Wire as follows referring to Figure 4.
a. Connect green and yellow-striped earth-ground
wires to earth-ground.
b. Select the appropriate method for wiring to the input
board from Figure 5 through Figure 13.
c. Connect incoming power to wire leads using a butt
splice or other method listed, certified, or otherwise
approved by local authorities. Leads are both black
for -AQ and -N5 models and are black and white for
-Y6 models.
d. Optional. Connect external 24V DC battery (not
supplied) in series with separate diode assembly
part 2600010 (supplied) to TB1 terminals 3 and 4
on the main board as shown in Figure 2 and
Figure 3 and marked on the diode assembly.
NOTE: Terminal Block TB1 can be unplugged from the
main board to complete wiring as shown in Figure 2.
Maintenance and testing
WARNING: To prevent fire, shock and component damage,
NO work including circuit board removal, should be
performed while the circuit is energized.
NOTE: Any kind of service or maintenance performed
while unit is energized will void the warranty.
Examine the unit semi-annually for accumulation of dirt.
Clean if necessary.
The Adaptatone should be tested annually or as required by
the authority having jurisdiction to ensure continuous
service.
