Pyronix Carbon Monoxide Detector

CO-WE (2nd Generation)

A Pyronix CO-WE (2nd Generation) to detect and protect from highly dangerous carbon monoxide (CO) gas. The CO-WE (2nd Generation) extends capabilities beyond security to detect highly toxic, colourless, odourless, tasteless and potentially deadly CO gas.

For use in residential properties where gas burning appliances are installed, the detector is an essential lifesaving device and upsell, which protects homes and families from CO; raising the alarm locally via its in-built 85dB sounder and remotely via connected Pyronix smart device apps, if any CO is present. 


  • Two-way wireless CO sensor
  • Detects harmful odourless carbon monoxide (CO)
  • Loud and obvious alarm
  • Low-battery supervision
  • Signal Strength Indicator
  • Pyronix High Security Wireless Encryption Protocol
  • No wires, no mess
  • One-Push-To-Learn Button

 Detect and protect from carbon monoxide with the new and improved CO-WE (2nd Generation). Be CO safe.

The CO-WE (2nd Generation) is an essential lifesaving device, which protects homes and families against this danger; raising the alarm locally via its 85dB sounder and remotely via connected Pyronix smart device apps, if CO is present.

Electrochemical detection for optimum performance

The CO-WE (2nd Generation)’s specially designed chamber allows CO into it. Once inside, a chemical reaction occurs that emits an electrical current as a by-product; the amount of electricity generated is directly proportional to the concentration of CO gas present in the atmosphere. The CO-WE (2nd Generation) determines the concentration by monitoring the electrical current; triggering the alarm if this is too high.

Loud and obvious alarms

The CO-WE (2nd Generation) has a built-in 85dB local sounder which works independently from the alarm panel, as well

as flashing LED lights when CO is detected. Alongside this, a detection alarm will be sent to the control panel to trigger an alarm, as well as send a voice push notification remotely to the user via connected Pyronix smart device apps. Providing an obvious alarm when CO is detected.

Be in control with full low-battery supervision

The main detection element of the detector features a fixed L91 lithium battery, continuously detecting within a property and providing peace of mind for 10 years – when running low, this is signalled as a fault on the control panel. The radio module itself has a CR123A battery, providing the usual lifespan of up-to 2 years. When the battery is running low on the radio module, the detector will send a signal to the control panel and the user will receive a push notification via their connected smart device app, to report the issue.

No wires, no fuss

Fully wireless means there is no need to run wiring by lifting floorboards or moving furniture; saving time and money.

Pyronix High Security Wireless Encryption Protocol

The two-way wireless protocol has been developed by Pyronix to ensure that the communication between all wireless system components are encrypted.

One-Push-To-Learn Button

A feature in all Enforcer wireless devices that means learning them onto the system can be done in seconds. A simple one-button learning feature for easy installation. Once in commissioning mode, the external test button of the CO-WE (2nd Generation) becomes the one-push-to-learn button, making installation quick and simple.

Signal Strength Indicator (SSI) on the Device

SSI in all Enforcer wireless devices allow them to be optimally positioned during installation, without the need to refer back to the panel.
