NOTE 1: Any other combinations of switch setting for

positions 1, 2, and 3 are invalid and should not
be used.

Consult the Directional Sound Applications Guide for
information regarding the appropriate power, speed, and
additional tone selections.

Electrical
Connect the Sounder as shown in Figure 1 for 2-wire appli-
cations. Connect the sounder as shown in Figure 2 for 4-
wire applications.

4-wire notification appliance circuits are circuits that use a
separate power supply and pair of wires for sounder and
strobe circuits. Some types of notification circuits may provide
coded signals to the sounders by pulsing the power supply on
and off in specific patterns such as the temporal 3 evacuation
signal. The directional sounders should not be connected to
4-wire sounder circuit power supplies where coded signals are
used to pulse the sounders. Directional sounders may be used
in conjunction with sync modules such as the System Sensor
MDL or syncable power supplies. The sounder is compatible
with syncable power supplies using any of the following syn-
cronization protocols; wheelock, gentex, and faraday.

All wiring must be installed in compliance with the
National Electrical Code (NEC) and applicable local codes
as well as special requirements of the authority having
jurisdiction.

NOTE: DO NOT loop electrical wiring under terminal

screws. Wires connecting the device to the control
panel must be broken at the device terminal con-
nection in order to maintain electrical supervision.

The sounder has a set of input terminals to provide addi-
tional control of the sound output of the directional sounder.
These terminals can be connected to the dry relay contacts
of control devices such as heat sensors or control modules.
When the input is active it will disable the sound output
of the Sounder. Connect the disable function as shown in
Figure 4. Refer to Table 3 for function switch settings.
