Kidde 260-CO Carbon Monoxide Detector with Alarm & Trouble Relays
The Kidde 260-CO is a commercial-grade carbon monoxide detector designed to provide accurate and reliable warning of potentially dangerous CO levels in residential and commercial environments.
The detector combines an advanced electrochemical CO sensor with an onboard microprocessor that continuously evaluates carbon monoxide levels over time. This technology provides dependable detection, fast response and reset, and strong immunity to false alarms.
Operating from 12 or 24 VDC, the 260-CO provides alarm and trouble relay functionality for integration with compatible fire alarm, security, and monitoring systems. It also includes an integrated 85 dBA temporal-4 sounder, LED status indication, and a one-touch TEST/HUSH button for convenient local operation.
A 10-year end-of-life signal provides notification when the CO sensing element reaches the end of its service life. When connected to an appropriately configured monitored system, this condition can also be transmitted to the supervising panel and central monitoring station.

Advanced Electrochemical CO Detection
The Kidde 260-CO uses an electrochemical sensing element to detect carbon monoxide in the protected area.
An onboard microprocessor evaluates information from the sensor and tracks CO concentrations over time. This provides accurate detection while helping the detector distinguish potentially hazardous carbon monoxide conditions from temporary environmental changes.
The combination of electrochemical sensing and intelligent processing provides quick response, reliable sensing, fast reset, and improved false alarm immunity.
10-Year End-of-Life Signal
The 260-CO incorporates a 10-year end-of-life signal to indicate when the carbon monoxide sensor has reached the end of its designed service life.
Rather than relying solely on a local indication, the detector can transmit its end-of-life condition to the supervising panel and, when the system is monitored and appropriately configured, to the central monitoring station.
This functionality helps facility personnel identify detectors requiring replacement before CO protection is compromised.
Integrated 85 dBA Sounder
An integrated 85 dBA sounder provides local audible notification when a carbon monoxide alarm condition is detected.
The sounder uses the temporal-4 pattern associated with carbon monoxide notification, helping occupants distinguish a CO event from other alarm conditions.
The detector can also be wired so that when one connected detector enters alarm, sounders on the other appropriately interconnected detectors are activated.
Alarm and Trouble Relays
The 260-CO is designed for integration with supervised systems and includes relay functionality for communicating detector conditions to compatible equipment.
A built-in trouble and power supervision relay provides system monitoring capabilities, while the 150 mA Form C relay supports integration with compatible control equipment.
This makes the 260-CO suitable for applications requiring more comprehensive monitoring than a standalone residential CO alarm.
SafeTest Functional Testing
The SafeTest feature allows technicians to perform a functional test using an appropriate spray containing real carbon monoxide gas.
This provides a means of verifying the response of the actual CO sensing element rather than testing only the detector's electronic circuitry.
The integrated TEST/HUSH button also simplifies routine local operation and testing.
LED Status Indication
An onboard LED provides visual indication of detector operating conditions, including alarm and trouble status.
Combined with the integrated sounder and relay outputs, this gives technicians and building occupants multiple ways to identify detector conditions.
Easy Installation
The 260-CO is designed to simplify installation and servicing.
Large SEMS terminals accommodate 14 to 22 AWG wiring, while the deep housing provides additional room for conductors and connections.
Its compact, contoured housing allows the detector to blend into residential and commercial interiors without compromising accessibility.
Replacement of 240-COe Detectors
An adapter plate is available to simplify installations where the 260-CO is being used in place of an existing 240-COe detector.
Installation requirements and system compatibility should always be verified before replacing an existing detector.
