1. Bring signaling circuit wires into electrical box or:
For weatherproof installation, fasten the Cat. No. 349
weatherproof box to the mounting surface by
installing the (3) #8 x 1-1/4" wood screws and three
fiber washers (supplied with the box) through the
mounting holes in the rear of the box. Note that "TOP"
inside of box indicates required position for
installation. Bring signaling circuit wires through
conduit and through conduit entrance hole into box.
Secure conduit to box.
For indoor installation, select a site that conforms to
the requirements given in the latest edition of NFPA
72, National Fire Alarm Code.
Edwards' DUOTRONIC signals, catalog numbers 5520D-AW
and 5520D-N5, are high decibel, diode-polarized, UL listed
signaling appliances intended for public mode fire alarm
signaling applications (per NFPA 72G) and other applications requiring electrical supervision of signaling circuit
field wiring. The 5520D-AW signal is dc powered and the
5520D-N5 signal is ac powered. The signals can operate
either as a horn or a siren and provide a switch for selecting the desired operating mode. The horn and siren tones
are produced electronically. When operated in the horn
mode, the signals can be used in coded signaling applications. The signals can be installed on any standard single
gang, 3-1/4", 3-1/2", 4" octagonal or 4" square electrical
box, or they can be installed outdoors using the Cat. No.
349 Weatherproof Box (ordered separately).

2. Disconnect the four-wire receptacle, shown in
Figure 5, from the signal plug. Connect the leads from
the receptacle to the signal circuit wires as shown in
Figure 3 for the Cat. No. 5520D-N5 signal or Figure 4
for the 5520D-AW signal. Polarity must be observed.
CAUTION
Use all leads for connection. Make sure to break wire run
to provide electrical supervision.
For additional information on wiring connections, refer
to the installation instructions supplied with the fire alarm
control panel or applicable system control panel.
3. See Figure 2. Loosen the screw at the bottom of the
signal housing and remove the mounting plate from
the signal.

CAUTION
To prevent damage to the signal, always ensure that the
signal is disconnected from the signaling circuit before
operating the horn/siren switch.
4. Select the desired operating mode by sliding the handle
of the horn/siren switch, located in the rear of the
signal housing, fully to the position marked "HORN"
or "SIREN".
5. Bring the four-wire receptacle through the center hole
of the mounting plate as shown in Figure 5. Align
appropriate holes in plate with mounting screw holes
in electrical box or with holes in bosses of Cat.

WARNING
This device will not operate without electrical power. As
fires frequently cause power interruptions, discuss further
safeguards with your local fire protection specialist.
Maintenance and Subsequent Testing
Maintenance and testing of the 5520D-AW and 5520D-N5
Duotronic Signals should conform to the requirements
given in the latest edition of NFPA 72. The standard requires you to examine the signal annually for accumulation of dust and dirt and clean when necessary.
Test the signal annually or at the intervals required by
applicable fire regulations and codes.
a. To single gang box--using the two #6-32 x 5/8"
screws supplied with signal.
b. To octagonal or square box--using screws supplied
with box.
c. To weatherproof box--using the four #8-32 x 7/16"
machine screws supplied with box.
6. Connect the signal plug with the receptacle and push
through mounting plate into box. Then hook signal
on mounting plate by engaging hanger on plate,
shown in Figure 5, into slot in top of signal housing.
Tighten screw, loosened in step 3, 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 posltion and
then tighten the nut. The speaker position can be adjusted within a 90 degree range vertically and 180 degree
range horizontally.
Operational Test
Apply power to the fire alarm or system control panel.
Initiate an alarm to activate the signal and verify that it
sounds and that the selected type of signal is sounding.
Reset the panel to silence the signal and return to the
supervisory mode.
