General Description
Before installing, please read the Directional Sound Applications Guide, available through System Sensor. The
installation must meet the requirements of the authority
having jurisdiction, CAN/ULC S524 and CSA C22.1. Directional sounders are used as supplemental signals on a
re alarm system to aid in the evacuation of building occupants. Although directional sounders may be connected to
notication appliance circuits (NAC) for re alarm service,
they are not a replacement for audible or visible notication
appliances as required by the authority having jurisdiction.
The directional sounder can be installed in systems using 24 Volt DC regulated power supplies only. It is not approved for use with FWR unregulated power supplies.
Directional sound is a broadband, multi-frequency sound.
The sound source is easily and quickly located by building occupants, making it ideal for rapid building evacuation. The sounder incorporates four different speed settings
which consist of broadband noise. The four speed settings
can be used to create an egress pathway out of a building. The speed setting should be set faster for units installed
at the perimeter exit. In addition to the broadband noise,
the sounder is capable of playing an alert message in the
form of a recorded voice message or other audible signals.
These messages will instruct the occupant of what action
to take as they approach the directional sounder. The voice
messages include: exit here, stairs up, stairs down, or area
of refuge.
Speed settings are made via DIP switches on the back
of the sounder.
Power Supply Considerations for
Directional Sounders
Panels typically supply DC ltered voltage or FWR (fullwave rectied) voltage. This device is only compatible with
DC ltered supplies and must not be used with panel sup-
plies that are FWR. Be certain the sum of all the device
currents do not exceed the current capability of the panel
power supply. Calculations are based on using the device
current found in Table 1 and must be the current specied
for the installed settings of the device.
Wire Sizes
The last device on the circuit must have sufcient voltage
to operate the device within its rated voltage range. When
calculating the voltage available to the last device, it is
necessary to consider the voltage drop due to the resistance of the wire. The thicker the wire, the less the voltage
drop. Generally, for purposes of determining the wire size
necessary for the system, it is best to consider all of the
devices as “lumped” on the end of the supply circuit (simulates “worst case”).
Typical wire size resistance:
18 AWG solid: Approximately 8 ohms/1,000 ft.
16 AWG solid: Approximately 5 ohms/1,000 ft.
14 AWG solid: Approximately 3 ohms/1,000 ft.
12 AWG solid: Approximately 2 ohms/1,000 ft.
Example: Assume you have 10 devices on a zone and
each requires 50mA average and 2000 ft. of 14 AWG wiring (total length = outgoing + return). The voltage at the
end of the loop is 0.050 Amps per device × 10 devices × 3
ohms/1000 ft. × 2000 ft. = 3 volts drop.

D690-06-00 1 I56-3071-000
The same number of devices using 12 AWG wire will produce only a 2 volt drop. The same number of devices using
18 AWG wire will produce an 8 volt drop. Consult your panel
manufacturer’s specications, as well as the sounder’s operating voltage to determine the acceptable voltage drop.
NOTE: If class “A” wiring is installed the wire length may
be up to 4 times the single wire length in this calculation.

Installation
Consult the Directional Sound Applications Guide (A051048-XXX) for information regarding the appropriate
mounting locations of directional sounders.
DIP Switches for Speed Settings
DIP switch positions 7-10 are used to select the speed setting of the sounder. Switch 10 is the fastest speed and is
used to mark perimeter exits and stairwells. The remaining settings are used for egress guidance to the perimeter
exits. The egress route would begin with the slow setting
(switch 7) and follow medium fast (switch 9) and medium
slow (switch 8) and nally the fast setting (switch 10). If
more than one switch is selected the sounder will default to
the fastest setting.
DIP Switch Settings for Alerting Messages
DIP switch positions 5 and 6 are used to select additional
tone pulses that can be inserted between bursts of directional sound pulses. These messages are used to give
building occupants instructions. There are four messaging
options to choose from. “Stairs Up” (Switch 5 off, Switch 6
on) will notify occupants that they are approaching a stairwell and will need to go up. “Stairs Down” (Switch 5 on,
Switch 6 off) will notify occupants that they are approaching a stairwell and will need to go down. “Area of Refuge”
(Switches 5 & 6 on) alerts people who need to nd these
areas of refuge in a building. “Exit Here” (Switches 5 & 6
off ) noties occupants that they have reached the perimeter exit.

Sound Output
DIP switch setting 4 enables a directional sound device to
become disabled when used in conjunction with devices
with dry contacts such as heat sensors or control modules.
The sounder has a set of input terminals that can be con-
gured for an “active open” or “active closed” state. When
the switch is in the “on” position, the sounder is “on” when
the disable connection is closed. When the switch is in the
“off” position, the sounder is “on” when the disable connection is open. See Table 3 for operation modes.

switch 2 selects the Medium setting, switch 3 selects the
Med-Low setting. If all three switches are “off” this selects
the High setting and if all three switches are “on” this selects the Low setting.

The sounder has a set of input terminals to provide additional 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

Two screws are included for attaching the sounder to the
electrical junction box.
NOTE: If surface mounting is required, an extension ring
will be necessary to give proper depth for mounting the
sounder. The minimum depth required, in the backbox/
extension ring combination, is 21/4˝. Any combination of
4˝ × 4˝ backbox and 4˝ × 4˝ extension ring that gives an
interior depth of at least 21/4˝ may be used.
Mounting
See Figure 6. The sounder can be ush mounted on a
4˝ × 4˝ × 21/4˝ back box, as follows:
A. Use the two 8-32 × 13/4˝ screws (provided) to attach
the Sounder to the back box.
B. Plug the remaining two holes that will not be used
for attachment with the plugs provided.
