GENERAL DESCRIPTION
The Atlas Sound Sequential Switch
System prevents high in-rush currents
which can damage drivers and sensitive
electronic equipment. The Sequential
Switch System applies power to the
system in desired time-delay sequence,
minimizing the potential for tripped
circuit breakers, blown fuses, or voltage
spikes caused by simultaneous power
application.
The system is ideal for large sound
reinforcement systems, electrical,
electronic systems/controls, and other
signal chains that require sequential
power up and power down.

SACR-191
Sequential Switch System Controller
The model SACR-191 is a six circuit
sequencer designed to sequentially
activate the associated SACS-1 and
SACS-5 117VAC power outlets. It can
be employed in sound reinforcement
systems or other electronic systems that
require a timed sequence for system
power-up. This means the SACR-191,
when used with the SACS-1 and/or
SACS-5 117VAC outlets will power
up and down a chain of equipment
in the desired order. Added flexibility
is incorporated by providing both a
24VDC output (for use with the SACS-1
and SACS-5) and a SPDT dry contact
closure on each circuit which can be
used for a variety of other applications.
The built-in clock generator is adjustable
and provides a means of setting the turnon delay of the six circuits.

The delay is adjustable from one to ten

for connecting the SACS-1 or
SACS-5 power outlets to the SACR-191.
Terminals are also available to connect a
remote sequence start/stop switch.
The cable necessary to interface the
SACR-191 controller with the remote
SACS-1 and SACS-5 is two conductor
cable- 22 ga. min. per circuit (not
included). The momentary remote
start/stop switch also requires a two
conductor shielded cable- 22 ga. min.
(not included).
The SACR-191 is powered by an
external power supply, which is included
with each unit. Controls include a master
power on/off switch, a sequence start/
stop switch, master power indicator light,
sequence status light, and circuit status
lights.

INSTALLATION INSTRUCTIONS
SACS-5
Six Circuit Remote for use with SACR-191 Controller
The model SACS-5 is equipped with six duplex for plugging in
mixers, equalizers, crossovers, amplifiers, etc. The first duplex
outlet is unswitched and can be used to plug in the power
supply to power the SACR-191 controller. A terminal strip is
located adjacent to each of the remaining five duplex outlets
to connect the individual circuits to the SACR-191 controller.
Each duplex outlet is further equipped with a manual/auto
switch to allow the outlets to be switched on manually and the
sequencing process to be overridden.

SACS-1
Single Circuit Remote for use with SACR-191 Controller
The model SACS-1 is a single circuit version of the
SACS-5. It is generally employed when separate power
circuits are a system requirement. It also simplifies power
control in a multi-rack system or control of remotely located
equipment.
All of the functions and features built into the SACS-1 are
identical to those in the SACS-5. The SACS-1 is built into a
surface mount three gang box suitable for rack or wall
mounting.
