Spec 1602
Model SEQ-4 Rev. 02-02-21 | pg. 1/4
Compact low voltage four step sequencer model SEQ-4 is
designed to work with a single external switch and low voltage
remote power controls (RPCs) to provide time-delayed activation
and deactivation of AC powered equipment on site or at remote
locations.
Note: This sequencer is for use with compatible components that feature classic
connections. It is not for use with devices that feature pass-through connections.
FEATURES:
• Power Requirement: 100-240VAC 12W
• Activation Trigger: Sequencing is initiated by a remote
external switch (order separately).
– The circuitry is designed to operate using a single remote
SPST switch with maintained contact closure.
– The sequencer can accept mulltiple switches if they have
momentary contact closure and Lowell MSM2 module is
connected between the sequencer and switches.
• Four (4) Step Delay:
– Time-delayed closure circuits activate in sequential order
(1, 2, 3, 4) and deactivate in reverse order.
– The delay between steps can be adjusted via an externally
accessible trimpot (0.5-10 seconds).
– LEDs provide visual status of the activation sequence.
– Includes auxiliary 24VDC output (300mA max.) for use with
remote indicators, if needed.
• Compact Chassis: 7" x 3.28" x 1.69" (4 lbs.) steel chassis
with black powder epoxy finish and mounting holes.
– Unit can be installed in a remote location or rack panel (2U).
– Operational diagram printed on top of chassis aids system
set-up.
• Country of Origin: Made in U.S.A. with global components
• Power Supply: UL Listed power supply (100-240VAC input,
24VDC 500mA output) with 6 ft. cord and NEMA 1-15P plug.
Includes three adaptors for international use (Schuko CEE
7/16, BS1362, AS3112).
• Installation: The sequencer is typically installed in a
convenient location, while remote power controls are placed
near equipment to be controlled—in another rack, room or
building.
– Maximum distance between switch, sequencer and remote
power controls: 22 gauge wire = 6,600 ft.; 18 gauge wire
= 17,160 ft.
– System Capacity: Accepts up to 10 RPCs per step.
• Connections: Order compatible remote power controls and
switches separately. (See last page.)
• A&E Specications: The four step sequencer shall be Lowell
model SEQ-4, which shall feature barrier strip terminals for
connection to a single external remote switch with maintained
contact closure (or multiple remote switches with momentary
closure and Lowell MSM2 module wired between the
sequencer and switches). The sequencer shall connect to
external remote power controls (RPCs) to activate remote
equipment in four steps with an adjustable time delay between
each step. It shall activate RPCs in order (1, 2, 3, 4) and
deactivate them in reverse order. The sequencer shall feature
a steel chassis with mounting holes, black powder epoxy
finish, and overall dimensions of 7" x 3.28" x 1.69". It shall
be made in the USA with global components, and include a UL
Listed power supply with NEMA 1-15 plug and three adaptors
(Schuko CEE 7/16, BS1362, AS3112). External switches and
remote power controls are required for sequencer use and
shall be ordered separately.

to the sequencer. The switch
features one LED and uses three
conductors.
Max. distance between SEQ-4 and
switch: 22-gauge wire = 100 ft.,
18-gauge wire = 200 ft.
Connect equipment to Lowell RPC Series
remote power controls that feature classic
connections (not pass-through), and connect
the RPC (switch and common terminals)
to one of the steps on the sequencer.
Up to 10 RPCs can be connected in parallel
on each of the sequencer’s four circuits.
Max. distance between SEQ-4 and RPCs:
22-gauge wire = 6,600 ft.,

Spec 1602
Model SEQ-4 Rev. 02-02-21 | pg. 3/4
Connect the sequencer to the MSM2 module,
then connect the MSM2 module to
multiple RPS Series switches that feature
MOMENTARY closure (release after being pushed).
Switches that have one LED use three conductors;
switches that have two LEDs use four conductors.
Max. distance between SEQ-4 and MSM2 module:
22-gauge wire = 100 ft., 18-gauge wire = 200 ft.
The MSM2 module includes two remote switch
terminal blocks. Terminals are parallel —
connected internally. Additional switches can be
added by making parallel connections at the MSM2
module, at a remote switch, or anywhere along
switch wiring. Maximum six (6) total.

Steps = Unit activates/deactivates connected remote power controls (RPCs) in four or eight steps, with a delay between each. Multiple RPCs can connect to each step.
Alternate Sequence Mode = The ASM feature skips selected outputs to allow partial startup of system, useful for small events or rehearsals. It requires remote switch
model RPSB-KP-ASM to enable ASM function before main switch is activated.
Onboard Switch = Sequencers without an onboard switch will require an external switch for activation.
REQUIRES A Remote Switch = Sequencer can be controlled by one external switch, usually placed in a remote location (RPS series switch with MAINTAINED closure).
ACCEPTS Multiple Remote Switches = Sequencer can be controlled by one or more external switches placed in remote locations (RPS Series switches with
MOMENTARY closure). Some models require the MSM2 module in order to accept multiple switches.
ACCEPTS Input from Alarm System = Sequencer can accept control override from an alarm system (alarm by others, not included).
ACCEPTS Input from Lowell Switch w/RJ45 = Sequencer is designed for use with a Lowell MOMENTARY switch that has a model number with "-RJ" as a suffix (see
options above). Note that these switches include a single RJ45 connector and are not part of Lowell's "pass-through" series.
NOTE: For rackmount sequencers that include AC power outlets, see Lowell ACR Series or ACSPR Series.
