Spec 1603
Model SEQ-8 Rev. 06-21-21 | pg. 1/4
INTERNAL USE ONLY: PN 24369
Compact low voltage eight step sequencer model SEQ-8 is
designed to work with single or multiple external switches 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 SPST switch or switches (order separately). Slide the
bar to select single or multiple switch mode.
– For Single Switch Applications: Use an SPST switch with
MAINTAINED contact closure.
– For Multiple Switch Applications: Use SPST switches with
MOMENTARY contact closure.
• Eight (8) Step Delay:
– Eight time-delayed closure circuits activate in sequential
order (1, 2, 3, 4, 5, 6, 7, 8) 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 sequence.
– Includes auxiliary 24VDC output (300mA max.) for use with
remote indicators.
• Compact Chassis: 10" x 3.28" x 1.69" 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 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 power sequencer shall be Lowell
model SEQ-8, which shall feature barrier strip terminals for
connection to a single external SPST switch with maintained
contact closure or multiple external SPST switches with
momentary closure. The sequencer shall connect to remote
power controls (RPCs) to activate equipment in up to eight
steps with an adjustable time delay between each step. It shall
activate the RPCs in sequential order and deactivate them in
reverse order. The sequencer shall feature a steel chassis
with mounting holes, black powder epoxy finish, and overall
dimensions of 10" 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 1-15P plug and three adaptors (Schuko
CEE 7/16, BS1362, AS3112). External switch(es) and remote
power controls are required for sequencer use and shall be
ordered separately.

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.
