The Nexelec AIR and AIR+ make up Nexelec’s series of interconnected CO detectors. Designed to enable you to maintain maximum safety at all times, these smart devices will automatically raise an alarm if Carbon Monoxide is detected.

Carbon Monoxide (CO) can be difficult to identify without a detector. The colourless, odourless and tasteless gas is extremely hazardous to human health and can be produced by log burning fires, gas boilers and burning other combustibles.

Designed to perform for up to 10 years, the Nexelec AIR and AIR+ provide a reliable option when looking to protect your buildings occupants. With a factory-calibrated CO sensor, this device is certified to ensure a reliable measurement throughout its entire lifespan.

With the ability to wirelessly interconnect with up to 25 additional Nexelec devices and accessories including the Nexelec ORIGIN series of LoRaWAN® Smoke Detectors, the AIR series can be used to enhance your building safety.

Ideal for use in Smart Buildings, Housing Associations, Student Accommodation and holiday lets, these interconnected CO detectors make it simple for landlords and building/facility managers to take care of their devices, wherever they may be. Landlords in England are required by law to ensure a carbon monoxide alarm is equipped in any room used as living accommodation which contains a fixed combustion appliance (excluding gas cookers) such as a log burning stove. This is also important in construction and those developing new build properties which will incorporate a fixed combustion appliance.

For additional protection, these devices also incorporate an LED light which acts as a pre-alarm function. Any reading over 40 ppm will present a red light which flashes every 30 seconds to alert users. If the level fails to drop below this reading after a certain amount of time, an audible alarm will be triggered to allow ventilation and evacuation of the premises.

By using LoRaWAN® technology, the Nexelec AIR and AIR+ also enable you to easily maintain digital logs of device statuses and to manage thousands of alarms wherever you may be.

Thanks to the intelligent NAVIXIS digital logbook, demonstrating compliance couldn’t be simpler. Data recorded by these interconnected CO detectors can be accessed through this smart dashboard, here, users are able to:

  • View a complete history of their devices including when it was installed and maintained.
  • Access all device status and data such as battery status and faults from one centralised platform.
  • With an API interface, this data can also be easily fed through to your chosen Management Software for a centrally managed system.
  • If maintenance is required, the logbook can be configured to send reminders when it’s time to check or replace detectors.

Suitable to be wall or ceiling mounted, the Nexelec interconnected CO detectors have a range of mounting options available to purchase separately.

With a discreet design, the Nexelec AIR/AIR+ can be easily integrated into any surroundings. These CO detectors are simple to install and have a long-lasting battery life of up to 10 years.

For those looking for additional functionality, the AIR+ combines carbon monoxide, temperature and humidity sensors in one neat device.
