Why choose AC power sequencing?
Many pro audio/video installations need audio power amplifiers to activate
last. Our solution is the AC power sequencer. The power sequencer provides AC power to outlet groups one at a time, thus allowing equipment to
be powered up and down in an orderly fashion by first providing power to
signal processing equipment and then providing power to the amplifiers.
When shutting down the A/V system, a sequencer will turn off the system
in the reverse order, hence the amps will be turned off first, and then the
signal processing equipment will be turned off last.
This is necessary because, as most sound reinforcement professionals
know, the majority of equipment damage occurs when devices are either
powered up or powered down. Power sequencing allows equipment
to power up in sequence and prevent the dreaded “pop”. The “pop”
is a speaker pop associated with on off switching of signal processing
equipment while the audio power amplifiers are energized. If the signal
processing “pop” is amplified sufficiently, the result can damage speaker
components. Because it prevents this unwanted, and often costly, circumstance, AC power sequencing is extremely valuable.
Furman Contractor Series equipment also allows sound reinforcement
equipment to be remotely powered up or powered down over a large
distance, not just in the immediate vicinity of the operator. Additionally,
Maintained or Momentary mode contact switching allows the user great
flexibility when controlling the unit from a remote location. A remotely
mounted switch or control pad can be used to sequence equipment on
or off. In addition, Furman Contractor Series remote functions can be
initiated across a room, on-site, or off-site with RS-232 protocol or our
cloud-based BlueBOLT technology.

SmartSequencing™
Furman SmartSequencing™ is a contractor-friendly technology that
makes AC power sequencing easy to employ by non-technical personnel. Multiple Furman Contactor Series units can be linked together using
inexpensive two conductor wire, thus creating a vast control system.
Generally, high-priced automation systems are used for large, innovative
installs, yet these control systems seldom combine AC power distribution, filtering, and protection. Furthermore, many automation systems are
difficult to implement on smaller budgets. SmartSequencing™ provides
the answer right out of the box by offering a simple approach to AC power
management and control. Furman’s newest power sequencing technology
is an end-to-end solution that is operational up to 1000 feet via a nonpolarized, isolated current loop. In situations where power sequencing is
critical, or more than one AC electrical circuit is utilized, wiring Furman
SmartSequencing™ products in series is simple, fast and reliable.
SMP (Series Multi-Stage Protection)
Furman’s SMP surge suppression virtually eliminates service calls and
costly “down time”. Traditional surge suppression circuits sacrifice
themselves when exposed to multiple transient voltage spikes, requiring
your system to be dismantled and your surge suppresser to be repaired.
This does not happen with Furman’s SMP. Damaging transient voltages
are safely absorbed, clamped, and dissipated. Your connected equipment
is protected, while your Furman protects itself! Its unparalleled clamping voltage is unique to Furman’s SMP. According to UL 1449 Clamping
Level is defined as the amount of voltage that is allowed to pass through
to your equipment when the protection device is subjected to a transient
surge or spike. While other designs offer clamping voltages that clamp
well above 330 Vpk, Furman’s SMP clamps at 188 Vpk, (133 VAC RMS)
even when tested with multiple 6000 Vpk - 3000 Amp surges. This
unprecedented level of protection is only available with Furman’s SMP
technology!
EVS (EXTREME VOLTAGE SHUTDOWN)
Furman’s trusted (EVS) over-voltage circuitry protects against prolonged
over-voltage conditions, such as accidental connections to 208 or 240
VAC or an intermittent loss of neutral. It does so by monitoring the incoming AC voltage. When an unsafe condition is detected, a relay shuts off
the incoming power until the overvoltage condition has been corrected.
The CN-1800S augments the EVS capability with Auto Reset options
allowing the end user to decide if the power should be reinstated, or remain off until conditions return to acceptable limits. The Extreme Voltage
Shutdown technology is a tremendous asset.
LIFT (LINEAR FILTERING TECHNOLOGY)
Unfortunately, traditional AC power conditioners have been designed
under unrealistic laboratory conditions. Professional audio/video components are constantly bombarded by electromagnetic interference (EMI)
and radio frequency interference (RFI) via their AC power source. Prior
technologies, whether they were multiple-pole or conventional seriesmode filters, could actually harm audio and video performance more than
they help, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs can actually add more than
10 dB of noise to the incoming AC line! Worse still, AC noise and ground
contamination frequently causes system reboots, sync issues and even
data loss. LiFT takes a different approach, ensuring optimal performance
through Furman’s linear AC noise filtering with no ground contamination.

Remote Access (and BlueBOLT®)
Important Safety Instructions
If so desired, the CN-1800S can be controlled remotely via an integral
RS-232 data-link and command protocol. The remote access feature
delivers integration with various control systems. The protocol set
provides over a dozen commands such as reset, disable, and sequence
and includes queries such as voltage, current, and power. Our optional
BlueBOLT® RS-232-to-Ethernet adaptor (available Q4, 2012) provides
additional control programming and monitoring from any Web-enabled
device via Telnet, direct HTTP connection, or www.mybluebolt.com
