ACSPR-SEQ6-2009

Rackmount panel with 9 outlets, sequencer, surge suppression

19”W rackmount panel with four step sequential power
and nine outlets (six switched, three unswitched) for
sequential activation/deactivation of connected equip­ment. Includes alarm interface and surge suppression.

Features

• Delay between sequenced steps (0.5-10 seconds)
is screwdriver adjustable

• Power rating of 120VAC, 60Hz/20A with EMI/RFI fil­tering. Each receptacle rated 15A.

• Rear termination blocks accommodate remote
switches, external triggers and an alarm system in­terface for use where mandated by fire code.

• Includes two dry contact closures (steps 5 and 6)
for triggering remote power control units (RPC se­ries, order separately).

• Actuation Switch: front panel rocker switch with mo-

mentary contacts (normally open SPST) plus rear
barrier strip termination blocks for momentary (nor­mally open) remote switches.

• Alarm Interface: lock on, lock off and switch lock

functions for alarm system or master control panel
applications.

• External Control Connections: plug-in barrier strip

terminal blocks

• EMI/RFI Filter: 19dB@500kHz, 42dB@30MHz

• Termination via 9 ft. attached cord with NEMA 5-20P
plug.

• Dimensions: 19"W x 1.75"H (1U) x 9"D

• Made in the U.S.A.

• ETL-listed in the U.S. and Canada to UL Standard
60065

• Advanced surge suppression protects against
surges up to 72,000A.

UL1449-2 adjunct results: 1000 surges, 6000 volts,
3000A, C1 and B3 waveforms (IEEE C62.41), no fail­ures.

– LEDs indicate status: if one section of the surge

suppressor has reduced protection, there are two
additional sections available to safeguard equip-

ment.
– Initial Clamping Voltage: 205V, UL rating 330V
– Endurance: IEEE C62.41-1991, B3 (C1), Pulses

(lifetime): 1kv≥1,000,000; 3kv≥100,000; 6kv≥5000

– Transient Noise Reduction: 25dB@100kHz,

50dB@1MHz
– Response Time: less than 5 nanoseconds
– Applicable Standards: IEEE standard 587-80 A & B,

IEEE standard C62.41-1991, IEC 1000-4-5-1995 (IEC

801-5).
– Protection Mode: line to neutral, zero ground leakage.

A & E Specifications

The sequential AC rackmount power panel shall be Lowell
Model No. ACSPR-SEQ6-2009. It shall be ETL listed and
have a power rating of 120VAC, 60Hz/20A with EMI/RFI fil­tering and a total of 9 outlets (6 switched, 3 unswitched)
and 2 steps providing contact closures to sequentially ac­tivate/deactivate equipment (4-6 steps) with a sequence
delay of 0.5 to 10 seconds. It shall be housed in a 1U steel
rackmount chassis measuring 19"W x 1.75"H x 9"D and
having color-coded LEDs. Activation shall be via a rocker
switch on the front panel. The panel shall also include
surge suppression

Note: Formerly Model No. ACSPR-SCS4-2009-RT2

ALARM SYSTEM INTERFACE

If required by local building code, facility usage,
or the Fire Marshal; the system switches can
be overridden and the system controlled by
contact closures provided by the fire alarm
panel or other control system. A maintained
contact between the “com” terminal and any of
the terminals shown here will provide the fol­lowing functions.

Lock Off: A maintained contact between the
“COM” terminal and the “LOCK-OFF” terminal
will turn the system off and keep it off regard­less of other switch activations. If the system is
already off, it will be kept off.

Lock On: A maintained contact between the
“COM” terminal and the “LOCK-ON” terminal
will turn the system on and keep it on regard­less of other switch activations. If the system is
already on, it will be kept on.

Switch Lock: A maintained contact between
the “COM” terminal and the “SWITCH-LOCK”
terminal will lock the system in its current state,
either on or off, regardless of any other switch
activations.

Caution: Do not allow alarm system to make
more than one of the contacts described above
at the same time. Controller board damage
may result.
