Furman CN-2400S – 20A SmartSequencing Power Conditioner

Product Overview

The Furman CN-2400S is a 20A rack-mount power sequencer and conditioner built for high-current commercial AV installations where staged power-up and equipment protection are critical. As a single-rack-unit Contractor Series sequencer, it combines SmartSequencing power control with Series Multi-Stage Protection and Linear Filtering Technology for demanding AV rack power management. It is designed for integrators specifying a 20A power conditioner for conference room, broadcast, and house of worship racks that draw more current than a standard 15A unit can supply. RS-232 and optional BlueBOLT IP control make it suited to control-system integration across multizone deployments.

Product Description

The CN-2400S delivers a full 20 amps through a NEMA 5-20P plug and 20A-rated NEMA 5-20R outlets, allowing it to power entire racks of high-current equipment. SmartSequencing technology lets an installer power an entire multizone system up or down safely from a single button press or key turn, with bidirectional links that coordinate multiple units across runs of up to 1,000 feet. This staged sequencing protects amplifiers, processors, and displays from the inrush current and thumps that occur when an entire rack is switched at once.

Protection is handled by non-sacrificial Series Multi-Stage Protection (SMP) surge suppression, Extreme Voltage Shutdown (EVS) for unsafe high or low voltage, and Linear Filtering Technology (LiFT) for wideband AC noise reduction. The unit provides eight rear-panel NEMA 5-20R outlets (six sequenced, two unswitched) plus a front-panel NEMA 5-15R convenience outlet, along with front-panel diagnostic indicators, a three-position keyswitch, configurable DIP switches, and a 20A thermal breaker. For installations that draw 15A or have lighter loads, integrators often specify the Furman CN-1800S 15A power conditioner with SmartSequencing; where battery backup is also required, the Furman F1500-UPS uninterruptible power supply complements a sequenced rack.

Key Features

• 20A Capacity — A NEMA 5-20P plug and 20A-rated outlets allow the CN-2400S to power entire racks of high-current AV equipment.
• SmartSequencing Technology — Bidirectional sequencing safely powers connected systems up and down from a single button or keyswitch, even for non-technical operators.
• Series Multi-Stage Protection (SMP) — Non-sacrificial surge suppression with zero ground leakage provides the highest level of surge and spike protection without wearing out.
• Extreme Voltage Shutdown (EVS) — The unit automatically powers down itself and connected equipment during unsafe high or low voltage conditions.
• Linear Filtering Technology (LiFT) — Wideband AC noise filtration preserves audio and video clarity across the connected system.
• Nine Total Outlets — Eight rear-panel NEMA 5-20R outlets (six sequenced, two unswitched) plus a front-panel NEMA 5-15R convenience outlet cover varied rack needs.
• RS-232 and BlueBOLT Control — An RS-232 interface with a published command set and optional BlueBOLT IP control enable integration with external control systems.
• Long-Distance Linking — Primary and secondary current-loop links support sequencing connections of up to 1,000 feet between units.
• Diagnostic Indicators — Front-panel lights report power, Protection OK, Extreme Voltage, link, and delay status for at-a-glance monitoring.

Typical Applications

• Boardroom
• Conference room
• House of worship
• Broadcast studio
• Auditorium
• Commercial meeting space

Frequently Asked Questions

What loads is the CN-2400S sized for?

It is a 20A unit with a NEMA 5-20P plug and 20A-rated outlets, intended to power full racks of high-current AV equipment that exceed the capacity of a 15A conditioner. Confirm your circuit provides a matching 20A NEMA 5-20R receptacle.

How does SmartSequencing simplify rack power-up?

SmartSequencing brings the six sequenced outlets online in staged delays so amplifiers and processors do not all draw inrush current at once. Primary and secondary links coordinate multiple units, so an entire multizone system can be powered up or down from one keyswitch or button.

How does it integrate with an AV control system?

The CN-2400S includes an RS-232 DB-9 interface with a published command set and supports optional BlueBOLT IP control, along with remote trigger and force-off terminals, so it can be driven from a third-party control processor.

Can it report voltage and current to the control system?

Yes. When queried over RS-232, the unit reports voltage with approximately ±2VAC accuracy and current with approximately ±1A accuracy for system monitoring.

How far apart can linked units be installed?

The primary and secondary current-loop links support sequencing runs of up to roughly 1,000 feet, which accommodates distributed racks within a building.

What warranty and support apply to this unit?

The CN-2400S carries Furman's 15-year limited warranty when purchased from an authorized dealer. For warranty validation, availability, and product support, contact Creation Networks at creationnetworks.net.
