The same number of devices using 12 AWG wire will pro-
duce 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 sounder's op-
erating 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 (A05-
1048-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 set-
ting of the sounder. Switch 10 is the fastest speed and is
used to mark perimeter exits and stairwells. The remain-
ing 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 finally 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 direc-
tional 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 stair-
well and will need to go up. "Stairs Down" (Switch 5 on,
Switch 6 off) will notify occupants that they are approach-
ing a stairwell and will need to go down. "Area of Refuge"
(Switches 5 & 6 on) alerts people who need to find these
areas of refuge in a building. "Exit Here" (Switches 5 & 6
off ) notifies occupants that they have reached the perim-
eter exit.

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-
figured 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 connec-
tion is open. See Table 3 for operation modes.

There are five different power settings for the sound output
pressure. Switch settings 1, 2, and 3 set the power set-
ting for the sounder. Switch 1 selects the Med-High setting,
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 se-
lects the Low setting.
Directional Characteristics are as follows:
-3dBA angles- 40, 130 horizontal and vertical
-6dBA angles- 15, 160 horizontal and vertical
