Description
Edwards' DUOTRONIC signals are heavy duty, high deci-
bel, UL listed signaling appliances intended for use in gen-
eral signaling and alarm applications. The 5520 series of
signals can operate either as a horn or a siren and provide
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.
The 5520 series of signals can be installed on any standard
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
Weatherproof Box (ordered separately). Also, the Cat. Nos.
5520-AS and 5520-AQ signals can be direct wall mounted.
The Cat. No. 5521-S1 signal can be installed indoors or
outdoors and is supplied with a Cat. No. 349-R Weather-
proof Box. The box must be used when installing the Cat.
No. 5521-S1 signal indoors as well as outdoors because it
contains a dropping resistor that is 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. Loosen the screw at the bottom of the signal housing
and remove the mounting plate from the signal (Figure
2).
2. Select the desired operating mode by sliding the handle
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. Mount the Cat. No. 598Y transformer on an electrical
box. Connect 240V AC power source wires to wire
leads from primary side of transformer using wire nuts
(not supplied) (Figure 4). Connect wires to be run to
signal to 24V terminals on secondary side of
transformer (Figure 4).
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 indicates required
position for installation.
a. Direct wall mounting--Cat. Nos. 5520-AS and 5520-
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.
