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

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 cal-

culation.

Installation

Consult the Directional Sound Applications Guide for

information regarding the appropriate mounting locations

of directional sounders.

Switch Settings

Selections are made via DIP switches on the back of

the sounder. Switch positions 7-10 are used to select the

pulse pattern of the sounder. Switch 10 is used to mark

the perimeter exit locations (fastest pulse). The remaining

settings are used for egress routing to the perimeter exit.

The egress route would originate with the “slow” (switch

7) tone and follow “medium 2” (switch 8) to “medium 1”

(switch 9) and finally the exit point “fast” (switch 10). If

more than one switch is selected the sounder will default

to the fastest selected setting.

Switch positions 5 and 6 are used to select additional

tone pulses that can be inserted in between bursts of the

directional sound pulses. The additional tone pulse will

be inserted on every 6th directional sound pulse. These

switches should be used when the sounder will be placed

near a stairway to guide a building occupant up or down

the stairs. Switch setting 5 inserts a down sweep indicat

ing the presence of a downward stairway. Switch setting 6

inserts an up sweep indicating the presence of an upward

stairway. If switch positions 5 and 6 are both set to “on”

this will insert a special tone for use near areas of refuge.

The area of refuge tone should be used if the directional

sounder is marking an area of refuge. This tone provides

a distinct signal indicating that the sounder is not mark-

ing an exit. If both switches are set to “off” the sounder

will default to no additional tones. In this case only the

directional sound pulses will be heard. See Table 2 for tone

selection options.

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

connection 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 setting

for the sounder. Switch 1 selects the 2 watt setting, switch 2

selects the 1 watt setting, switch 3 selects the

/2 watt setting.

If all three switches are “off” this selects the 4 watt setting and

if all three switches are “on” this selects the

/4 watt setting.
