CO100Ar – Carbon Monoxide Gas Sensor

The CO100AR is a sensor for detection of Carbon Monoxide (CO). The sensor is compatible with the complete range of Duomo conventional gas controllers. It features a Time weighted average (TWA) that can indicate when gas levels have been over lower levels for a set time periods.

Other versions

  • CO233A is a version with a display.
  • CO100P is set up for use in car parks.

CO100AR – Carbon Monoxide Gas Sensor Certified EN50291 for Toxic Gas 12-24V DC Supply

The CO100AR is an essential Carbon Monoxide gas sensor, designed for professionals in the gas safety and control industry. It provides a 4-20mA signal output that is sent to any of the Duomo controller panels listed. Making it easy to monitor and track CO levels accurately. But there’s more to this clever sensor than just its signal output. It also features a Time Weighted Average (TWA) function. This provides a signal if gas levels stay above a concentration over a given time period, such as 30ppm for 120 minutes. This makes the CO100AR sensor invaluable for monitoring CO levels in boiler rooms as part of a complete gas detection system.

Certified EN50291 for Toxic Gas

The CO100AR sensor is Certified EN50291 for Toxic Gas. A reliable solution for detecting Carbon Monoxide (CO) in various applications. It is designed with electrochemical sensor technology for accurate detection and measurement.

4-20mA Signal Output

With the CO100AR sensor’s 4-20mA signal output, you can monitor and track CO levels easily. It features both linear and on/off time-weighted average signals.

Compatibility with Various Gas Controllers

The CO100AR sensor is compatible with Duomo’s GS100M, GS300M, GS300Mc, BX444Mc, BX150, and BX316 conventional gas controllers. It offers a seamless integration experience.

Protective Ratings

Offering IP66 protective rating for enclosure and IP65 protective rating for the sintered head. The CO100AR sensor performs well even under harsh working conditions. It is built to last and ensures safety and reliability.

CE Certified

The CO100AR sensor is CE certified as per no. 96125. It meets the strict safety and performance standards set by the European Union.

Multiple Versions

The CO233A is a CO100AR sensor version with a display, allowing for easy readings and visual validation of CO levels.

The CO100P is specifically set up for use in car parks, providing a tailored solution for CO monitoring needs in such environments.

FAQs

How do I know how many sensors I need and the area each sensor covers?

Each sensor covers an area of 6 metres diameter

What height should the sensor be mounted?

The position of the sensor is a crucial factor for its correct functioning. The sensor must be placed at a height of 160 cm from the lowest point on the floor.

The sensor must not be placed near furnaces, fuel-burning kitchen appliances, fireplaces, ranges, suction fans, ventilation fans, windows, doors. Smoke vapour and sources of heat could distort its measurement.

What do the LED indicator colours mean?

GREEN
When the LED is Green in colour it indicates that the toxic gas threshold has not been exceeded and the sensor is in normal condition.

CYAN
When the LED is Cyan in colour it indicates the maximum average concentration to which an unprotected worker may be exposed in any eight-hour interval during the
day has been detected (20ppm) and the main alarm relay has triggered.

MAGENTA
When the LED is Magenta in colour it indicates that the maximum average concentration to which an unprotected worker may be exposed in any fifteen-minute interval during the day has been detected (100ppm) and the main alarm relay has triggered.

RED
When the LED is Red in colour it indicates the toxic gas threshold has been reached or passed. If the 300 ppm has detected the main alarm relay is triggered immediately.

YELLOW
When the LED is Yellow in colour it indicates a sensor fault. This immediately triggers the fault relay

What is the TWA & STEL alarm?

TWA Time weighted average alarm is activated if the 8 hours average is over 20ppm. LED indicator illuminates CYAN

The STEL Short Term Exposure Limit alarm is activated if the 15 minutes average is over 100ppm. LED indicator illuminates MAGENTA

Fault LED is illuminated

Check that the cables are connected according to the drawing, and that the wire isolation sheath has not been pinched.

Check the voltage at the terminals 1-2.
It must be a minimum of 11VDC and a maximum of 25VDC.

Check the voltage at the terminals 2-3.
It must be a minimum of 0.8 VDC to a maximum of 1.1 VDC.

The sensor does not power up

Check that the 12/24 VDC power is present, and that positive and negative polarity has not been inverted.
