INTERNAL USE
ONL
Y:
PN 24375
The low voltage rackmount sequencer is used in conjunction with
remote power controls (RPCs) to provide time-delayed activation
and deactivation of connected equipment, often located in another
rack, room or building. The sequencer can also control accessory
systems such as projector screens, lighting or blinds. To initiate
sequencing, use the rocker switch on the front panel or connect
an external switch to the rear terminal block for remote activation.
Note: This sequencer is not for use with devices that feature pass-through
connections.
FEATURES:
•
Power Required:
100-240 VAC 500 mA max
•
Rackmount Chassis:
19" x 9" x 1U steel chassis with black
powder epoxy finish. 12 lbs.
•
Activation Switch:
– Sequencing is initiated by the front rocker switch
with
momentary contacts (normally open SPST).
–
Includes rear barrier strip termination blocks with parallel
RJ45 jacks for optional remote switches (momentary, normally
open).
•
Eight Step Sequencer:
– Eight time-delayed closure circuits activate in sequential
order (1, 2, 3, 4, 5, 6, 7, 8) and deactivate in reverse order.
– Delay between steps can be adjusted via a trimpot on the
front panel (0.5-10 seconds).
– LEDs provide visual status of the sequence.
– Includes auxiliary 24VDC output (300mA max.) for use with
remote indicators.
•
Alarm System Interface:
– Integral override facilitates use in life safety applications
where fire code mandates an alarm interface.
–
Lock on, lock off and switch lock functions for alarm system or
master control panel applications.
•
Outputs:
– SPST relay contact closure (3A), removable phoenix style
terminals and parallel RJ45 jacks. Each output can be
connected to up to 50 remote power controls (RPCs).
–
Rear barrier strip termination blocks with parallel RJ45 jacks
for optional remote switches (momentary, normally open).
•
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 installed in a rack, while remote
power controls are placed near equipment to be controlled—
in another rack, room or building.
– Maximum wire distances between sequencer and remote
power controls: 24 gauge wire = 20,000 ft.; 22 gauge
wire = 31,200 ft.; 18 gauge wire = 76,800 ft.
– System Capacity: Accepts up to 50 RPCs per step.
•
Country of Origin:
Made in U.S.A. with global components
•
Connections:
Order compatible remote power controls and
switches separately (see last page).
A&E SPECIFICATIONS:
The power sequencer shall be Lowell model SEQR-8-RJ, which
shall include a rocker activation switch, LEDs and an accessible
trimpot for delay adjustment of sequence operation. Rear panel
shall include Phoenix-style removable terminals and parallel
RJ45 jacks for each SPST relay contact closure output. It shall
include a separate alarm interface connection. The power
sequencer shall be used with Lowell RPC Series remote power
controls (ordered separately). The sequencer shall be made in
the U.S.A. with global components.
Rackmount Sequencer (8 step): SEQR-8RJ
Made in USA
Red LED:
FLASHING = down cycle in progress; STEADY ON = down cycle completed (system off)
Green LED:
FLASHING = up cycle in progress; STEADY ON = up cycle completed (system on)
Rocker Switch:
starts sequence
up or down. Activation in mid-cycle
reverses direction.
Delay Adjust
:
recessed trim pot
Eight LEDs:
light to indicate progress of sequence (up or down).
