Furman CN-1800S – 15A SmartSequencing Power Conditioner

Product Overview

The Furman CN-1800S is a 15A rack-mount power sequencer and conditioner designed for commercial AV installations that require staged power-up, surge protection, and noise filtration in a single rack space. As a Contractor Series SmartSequencer, it combines AC power distribution, Series Multi-Stage Protection, and Linear Filtering Technology for reliable AV rack power management. It suits integrators specifying a 15A power conditioner for conference room, house of worship, and training room racks where loads stay within a standard 15A circuit. RS-232 control and optional BlueBOLT IP control make it well matched to control-system integration across multizone deployments.

Product Description

At the core of the CN-1800S is SmartSequencing technology, which lets a primary unit control multiple secondary units across an installation so that zones and devices power up and down in a defined order. Units communicate bidirectionally over runs exceeding 1,000 feet and remain backward compatible with legacy sequencers, which makes the CN-1800S straightforward to add to an existing system. Staged sequencing protects connected amplifiers, processors, and displays from inrush current and audible thumps when an entire rack is switched.

Protection comes from non-sacrificial Series Multi-Stage Protection (SMP), Extreme Voltage Shutdown (EVS) for sustained under- or over-voltage events, and Linear Filtering Technology (LiFT) for wideband AC noise reduction. The unit provides nine total outlets — eight on the rear panel and one front-panel convenience outlet — with up to 15 amps of output protected by a thermal breaker, plus front-panel diagnostic lights, a security keyswitch, configurable DIP switches, and fire-alarm shut-off. For racks that draw more than 15 amps, integrators can step up to the Furman CN-2400S 20A Smart Sequencer; the full Furman power product collection covers conditioners and battery backups for the rest of the rack.

Key Features

• 15A Capacity — A NEMA 5-15P plug and 15A-rated outlets supply up to 15 amps of sequenced, protected power for standard AV racks.
• SmartSequencing Technology — Bidirectional sequencing lets a primary unit power multiple secondary units up and down in a defined order from a single button or keyswitch.
• Series Multi-Stage Protection (SMP) — Non-sacrificial surge suppression with zero ground leakage absorbs and clamps transient surges without damaging internal circuitry or connected equipment.
• Extreme Voltage Shutdown (EVS) — The unit powers down itself and connected devices during sustained under-voltage or over-voltage conditions, with configurable auto or manual reset.
• Linear Filtering Technology (LiFT) — Wideband AC noise filtration reduces interference evenly across the audio and video bandwidth for cleaner performance.
• Nine Total Outlets — Eight rear-panel NEMA 5-15R outlets (six sequenced, two unswitched) plus a front-panel 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 third-party control systems.
• Security and Fire-Alarm Features — Security covers and a sequence keyswitch prevent tampering, and a fire-alarm shut-off input supports life-safety integration.
• Long-Distance Linking — Current-loop primary and secondary links support sequencing connections of over 1,000 feet between units.

Frequently Asked Questions

What loads is the CN-1800S sized for?

It is a 15A unit with a NEMA 5-15P plug and 15A-rated outlets, intended for AV racks whose total draw stays within a standard 15A circuit. For racks that need more headroom, the 20A CN-2400S is the equivalent higher-capacity model.

How does SmartSequencing simplify rack power-up?

The six sequenced outlets come online in staged delays so connected gear does not draw inrush current all at once. A primary unit can drive multiple secondary units, allowing an entire multizone system to be powered up or down from a single keyswitch or button.

How does it integrate with an AV control system?

The CN-1800S includes an RS-232 DB-9 interface with a published command set and supports optional IP control through the BB-RS232 adaptor for Telnet, HTTP, or BlueBOLT, plus remote trigger, force-off, and fire-alarm terminals.

Is it backward compatible with older Furman sequencers?

Yes. The CN-1800S is backward compatible with legacy sequencers, so it can be added to an existing sequenced system without replacing prior units.

Can it report voltage and current to the control system?

With the RS-232/Ethernet option, the unit reports voltage with approximately ±2VAC accuracy and current with approximately ±1A accuracy for system monitoring.

What warranty and support apply to this unit?

The CN-1800S 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.
