Silent Knight SK-FIRE-CO-W Addressable Combination Fire/CO Detector

Product Overview

The Silent Knight SK-FIRE-CO-W Addressable Combination Fire/CO Detector is a commercial, ceiling-mounted multi-sensor detector designed to provide both fire detection and carbon monoxide (CO) detection in a single addressable device. By combining multiple sensing technologies, the SK-FIRE-CO-W can identify multiple components associated with a fire while providing a separate signal for life-safety carbon monoxide detection.

For fire detection, the detector uses four sensing elements: smoke, carbon monoxide, light/flame, and heat. This multi-criteria approach is designed to improve detection of real fire conditions while helping provide increased immunity to nuisance particulate. The detector also uses automatic drift compensation for the smoke sensor and CO sensing cell.

The SK-FIRE-CO-W uses only one address on the Signaling Line Circuit (SLC), helping simplify system design while providing multiple detection capabilities from a single device. When paired with a compatible B200S or B200S-LF base, the detector can provide separate audible signaling for fire and CO alarm conditions.

The built-in electrochemical CO sensing cell provides a dedicated CO detection signal, while a CO cell end-of-life warning and fault indication help identify service conditions. The detector also supports RealTest® CO testing capability for system testing and maintenance.

Designed for use with Silent Knight 5000 and 6000 Series addressable fire alarm control panels, the SK-FIRE-CO-W is a practical solution for commercial fire and carbon monoxide detection applications.

Multi-Sensor Fire Detection

The SK-FIRE-CO-W combines four sensing elements in one detector to monitor different characteristics associated with fire conditions. These include:

• Smoke
• Carbon monoxide
• Light/flame
• Heat

Using multiple sensing inputs allows the detector to evaluate different fire signatures rather than relying on a single detection method. The combination is designed to provide enhanced sensitivity to real fire conditions while improving immunity to nuisance particulate.

Dedicated Carbon Monoxide Detection

In addition to its fire detection capabilities, the SK-FIRE-CO-W includes an electrochemical carbon monoxide sensing cell that generates a separate signal for life-safety CO detection. Automatic compensation helps account for sensor drift, while the detector provides CO cell end-of-life warning and fault information for maintenance purposes.

Addressable System Compatibility

The SK-FIRE-CO-W is an addressable wired detector that uses a single SLC address. It is designed for compatibility with Silent Knight 5000 and 6000 Series addressable fire alarm control panels, making it suitable for integrated commercial fire and CO detection systems.
