GENERAL DESCRIPTION
Before installing, please read the Directional Sound Applications Guide, avail-
able 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 fire alarm system to aid in the
evacuation of building occupants. Although directional sounders may be con-
nected to notification appliance circuits (NAC) for fire alarm service, they are
not a replacement for audible or visible notification 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 cre-
ate 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 filtered voltage or FWR (full-wave rectified) volt-
age. This device is only compatible with DC filtered supplies and must not be
used with panel supplies that are FWR. Be certain the sum of all the device
currents do not exceed the current capability of the panel power supply. Cal-
culations are based on using the device current found in Table 1 and must be
the current specified for the installed settings of the device.
WIRE SIZES
The last device on the circuit must have sufficient voltage to operate the de-
vice 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 resis-
tance 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.
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 specifications, as well as the sound-
er'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.
