Edwards Signaling 5531MHV - Manual (Page 2)

2 / 8 P/N 3100008 • REV 4 • ISS 09AUG10
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.
1. Mount Adaptatone as shown in Figure 1.
a. Flat Surface Mounting. Secure unit to mounting
surface using the (4) mounting holes in the mounting
plate on the rear of the box. Use the #10 x 3" (76
mm) wood screws (furnished loose) or other hardware
(not supplied) suitable for the mounting surface.
b. Rigid Pipe Mounting. Loosen the (4) cover screws
from the signal box and lift off signal box cover.
NOTE: Cover screws are captive. Do not remove from cover.
Remove the center knockout in lower wall of box and
mount box to a 1/2” (12.7 mm) conduit pipe using
suitable connector.
2. Wire in accordance with the instructions in “Wiring.”
3. Refer to Figure 5 and Table 6 and select desired tones.
Set miniature programming switches on the input board.
For input connected to IN1, set on SW1; IN2, set on SW2;
IN3, set on SW3, and IN4, set on SW4, in order of priority
desired.
WARNINGS: HIGH VOLTAGE is present when product is
energized.
High volume may cause harm to personnel in close proximity.
4. Adjust volume level, if desired, by turning potentiometer
located on the main board (Figure 5 and Figure 6).
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.
5. To adjust speaker direction, loosen large star nut
(Figure 1) and turn speaker to the approximate desired
position. Retighten nut and turn speaker slightly clockwise
until locked into place.
WARNINGS: To ensure integrity of the enclosure: Ensure the
cover gasket, part number P-007549-0069, is adhered into
groove at cover perimeter before replacing the signal box
cover.
Ensure that the (4) collar gaskets, part number P-041930-
0362, are in place on each cover screw before securing the
signal box cover.
When securing cover, start screws by hand, making sure they
are threaded into tapped holes in housing bosses before
securing with a screwdriver. Torque signal box cover screws
to a minimum of 20 in-lbs. This ensures the required tight fit.
6. Tightly secure the signal box cover using (4) retained
cover screws.
7. Torque signal box cover screws to a minimum of 20 in-lbs.
8. 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"
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.
If Edwards Signal Actuator catalog number 5538-4 is used
to manually initiate tones, connect its four normally-open
switches to the Tone Generator as shown on instructions
provided with the Signal Actuator unit.
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 7 - Figure 11 models with 24 V
input boards and Figure 12 and Figure 13 for models
with 120 V input board. Connect the Adaptatone as
shown.
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 24 VDC 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 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 and Figure 3.
Maintenance and testing
WARNINGS: 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.
