Description
Edwards' DUOTRONIC signals are heavy duty, high deci-
bel,ULlistedsignalingappliancesintendedforuseingen-
eral signaling and alarm applications. The 5520 series of
signalscanoperate either as ahornor a siren andprovide
a switch for selecting the desired operating mode. The
5521-S1 signal operates as a horn only. The horn and si-
ren tones are produced electronically. Signals operating
in the horn mode can be used in coded signaling applica-
tions.
The5520seriesofsignals can be installed on anystandard
single gang, 3 1/4" (83 mm), 3 1/2" (89 mm), or 4" (102
mm) octagonal, or 4" (102 mm) square electrical box, or
they can be installed outdoors using the Cat. No. 349
WeatherproofBox(orderedseparately). Also,theCat.Nos.
5520-ASand5520-AQsignals can be direct wallmounted.
The Cat. No. 5521-S1 signal can be installed indoors or
outdoors and is supplied with a Cat. No. 349-R Weather-
proofBox. Thebox must be usedwhen installing the Cat.
No. 5521-S1 signal indoors as well as outdoors because it
containsadroppingresistorthatis required for operation
of the signal.

WARNING
Before beginning the installation of the signal,
ensure that the power source for the signal is
disconnected.
1. Loosenthescrew at thebottom of thesignal housing
andremovethemountingplatefromthesignal(Figure
2).
2. Selectthedesiredoperatingmodebyslidingthehandle
of the horn/siren switch, located in the rear of the
signal housing, to the applicable selection.
NOTE: For Cat. No. 5520-R5 signal, proceed to step 3.
For all other 5520 Series models, proceed
directly to step 4.
3. Mountthe Cat. No. 598Y transformer onan electrical
box. Connect 240V AC power source wires to wire
leadsfromprimaryside of transformer using wirenuts
(not supplied) (Figure 4). Connect wires to be run to
signal to 24V terminals on secondary side of
transformer(Figure4).
4. Install wires from power source, or for Cat. No. 5520-
R5 signal, install 24V power source wires from Cat.
No. 598Y transformer. Install signal mounting plate
using one of the following procedures:
NOTE: "TOP" on mounting plate and on inside of Cat.
No.349 Weatherproof Box indicatesrequired
position for installation.
a. Directwallmounting--Cat.Nos. 5520-ASand5520-
AQ only:
Bring power source wires through hole in wall
and through center hole in mounting plate.
Fasten mounting plate to wall by installing the
three #8 x 1 1/4" (32 mm) wood screws, supplied
with the signal, through the appropriate holes in
mounting plate as shown in Figure 3.
CAUTION
To prevent damage to the signal, always ensure that
power is off before operating the horn/siren switch.

b. Mounting to electrical box:
Bringwiresinstalledin step 4 through center hole
of mounting plate.
Align appropriate holes in mounting plate with
mounting screw holes in electrical box. Fasten
plate to single gang box using the two #6-32 x 5/
8" (16 mm) screws supplied with the signal, or
fasten to octagon or square box using screws
supplied with the box.
c. Weatherproofinstallation:
Fasten the Cat. No. 349 Weatherproof Box to the
mounting surface by installing the three
#8 x 1 1/4" (32 mm) wood screws and three fiber
washers, supplied with the box, through the
mounting holes in the rear of the box.
Bring wires installed in step 4 through 3/4" (19
mm)-14NPTconduitandthroughconduitentrance
hole into box. Secure conduit to box.
Align appropriate holes in mounting plate with
mountingscrew holes in bosses of box andfasten
plate to box using the four #8-32 x 7/16" (11 mm)
machine screws supplied with the box.
5. Connect wires from power source or transformer to
theterminals of the plugreceptacle on the mounting
plate as shown in Figure 3.
6. Hook signal on mounting plate by engaging hanger
on plate into slot in top of signal housing (Figure 3).
Press signal flush to mounting plate to mate plug in
rear of signal housing with plug receptacle on
mountingplate. Tightenscrew,loosened instep 1, to
secure signal to plate.
For Cat. No. 5521-S1, install as follows:
1. Loosenthescrew at thebottom of thesignal housing
andremovethemountingplatefromthesignal(Figure
2).
2. Fasten the Cat. No. 349-R Weatherproof Box to the
mounting surface by installing the three #8 x 1 1/4"
(32mm)woodscrewsandthreefiberwashers,supplied
withthe box, throughthe mounting holesin the rear
of the box.
3. Bring 250V DC power source wires through 3/4" (19
mm)-14 NPT conduit and through conduit entrance
hole into box. Secure conduit to box.
4. Place resistor bracket assembly P-039964-0424 in box
with resistor facing rear of box as shown in Figure 5.
Connectthe250Vpowersourcewirestotheterminals
on the assembly (Figure 4).
5. Bring the two wire leads from the resistor bracket
assembly through the center hole in the mounting
plate. Align holes in bracket with mounting screw
holes in lower bosses of box when upper conduit
entrancehole isused(Figure5). When bottomconduit
entrance hole is used, bracket must be aligned with
screw holes in upper bosses in box.
6. Align appropriate holes in mounting plate with
mounting screw holes in bosses of box, and fasten
plate and resistor bracket assembly to box using the
four #8-32 x 7/16" (11 mm) machine screws supplied
with box.
7. Connect wire leads from resistor bracket assembly to
theterminals of the plugreceptacle on the mounting
plate (Figure 3).
8. Hook signal on mounting plate by engaging hanger
onplateintoslotintop of signal housing. Press signal
flushto mounting plate to mate plug inrear of signal
housing with plug receptacle on mounting plate.
Tighten screw loosened in step 1 to secure signal to
plate.
Adjusting Speaker Direction
To adjust the speaker direction, loosen the nut shown in
Figure 2. Rotate the speaker to the desired position and
tighten the nut. The speaker position can be adjusted

OperationalTest
Apply power to the signal and verify that it sounds. For
modelswith horn/sirenmodeselection,verify thatselected
type of signal is sounding.
Maintenance and SubsequentTesting
