Wiring
WARNING: Risk of death or serious injury. To prevent fire and
shock, wire the 5530MD-24AW only as described in this
installation sheet.
Caution: Equipment damage hazard. To ensure proper
supervision of connections, do not use looped wires under
terminal screws. Break the wire run. Use both sides of the
terminal screws as shown in Figure 2.
Note: Terminal block TB1 can be unplugged from the main
board to complete the wiring as shown in Figure 2.
1. Wire the 5530MD-24AW to a supervised signaling circuit
as follows:
a. Connect the green ground and yellow striped earth-
ground wire to earth ground.
b. Connect the incoming power to TB1-1 and TB1-2 as
shown in Figure 2. Polarity must be observed.
c. Connect the wires leading to the next signal or end-of-
line resistor to TB1-1 and TB1-2 as shown in Figure 2.
Polarity must be observed.
2. Set the miniature programming switches on the input
board. Refer to Figure 3 and Table 1 to select desired
tones.
WARNING: Risk of death or serious injury. High voltage is
present when the appliance is energized. High volume may
cause harm to personnel in close proximity.
3. Adjust the volume level, if desired, by turning the
potentiometer located on the motherboard as shown
Figure 3.
Caution: Equipment damage hazard. To ensure the integrity of
the 5530MD-24AW assembly when adjusting the speaker
direction, make sure the threads in the enclosure remain fully
engaged and do not turn the speaker more than 360 degrees
from the original factory installed position.
4. To adjust the speaker direction, loosen the large star nut
(see Figure 1) and turn the speaker to the approximate
desired position. Retighten the nut and turn the speaker
slightly clockwise until it is locked into place.
Cautions
Equipment damage hazard. Ensure that the cover gasket (part
number P-007549-0069) is adhered into the groove at the
cover perimeter and that the four collar gaskets (part number
P-041930-0362) are in place on each cover screw before
replacing the signal box cover.
Equipment damage hazard. When securing the cover, start the
screws by hand, making sure they are threaded into the tapped
holes in the 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.
5. Secure the signal box cover using the four retained cover
screws. Torque the signal box cover screws to a minimum
of 20 in-lbs.
6. Verify operability.
Maintenance
WARNING: Risk of death or serious injury. 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 the
unit is energized will void the warranty.
Examine the unit semi-annually for accumulation of dirt. Clean
if necessary.
The 5530MD-24AW should be tested annually or as required
by the authority having jurisdiction to ensure continuous
service.
