Supervised Audio System Common Control Module (SADC)
The supervised audio system common control module (SADC) provides all of the control capabilities to the SAFEPATH panel. The
controller module monitors the digital voice module or line level interface module, the battery charger module, and the amplifier
modules for proper operation. The microphone is monitored for connection.
The line level input is monitored to determine its status, active or inactive. If the status is inactive, the control module routes a
supervision tone to each of the amplifier modules and monitors the amplifier for functionality. If the status is active, the control
module routes the audio from the line level input to the four amplifier modules.
The battery charger module is monitored for three conditions: low AC input power, battery wiring trouble, and battery voltage low.
The wiring between the controller module and the battery charger is supervised for open and short circuit conditions.
The amplifier modules are supervised for two failure conditions: field wiring trouble conditions and amplifier audio output trouble
conditions. The controller module only supervises the audio output during standby conditions. When either a message is playing
from the digital voice module or a live announcement is being made from the microphone, the field wiring and audio output are not
supervised.
If at any time a trouble condition is detected, the controller module will energize the internal and external trouble audibles, transfer
the Form C trouble contact to the trouble position, turn off the “NORMAL” indicator, and turn on the “TROUBLE” indicator.
There are two fuses on the printed circuit board, F1 and F2. F1 is the remote microphone power fuse and F2 is the fuse for the
external trouble audible. See Figure 25 for fuse location.

Configuration
There are 8 dip switches used to configure the SAFEPATH system:
They are:
SW8
Position 1, REMOTE MICROPHONE ENABLE (RM). ON configures the system to use an optional Remote Microphone.
OFF configures the system to use no Remote Microphone.
SW8
Position 2, SYNCHRONIZED STROBES ENABLE (SS). ON configures the system to use synchronized strobes. OFF
configures the system to use non-synchronized strobes.
SW8
Position 3, Remote SAFEPATH ENABLE (SL). ON configures the system to be a remote SAFEPATH panel. OFF
configures the system to be a central or stand-alone SAFEPATH panel.
SW8
Position 4, Future Use (FU). Leave in OFF position.
SW9
Position 1, LAMP TEST ENABLE (LT). ON lights the panel LED’S for test purposes, leave in OFF position.
SW9
Position 2, 3, & 4, MULTITONE SELECT (TS1, TS2, & TS3) selects 1 of 8 tones used for the primary evacuation signal.
Use Table 2 below to select the tone.
