Easy-to-install, wall mounted, modular carbon dioxide concentration monitor and warning alarm system, providing continuous monitoring of carbon dioxide concentration in the surrounding air and both visual and audible alarms when these fall outside pre-set levels.

• Monitor operates continuously and cannot be switched off, giving maximum user protection
• Built-in visual and audible alarms with separate ‘high’ (1,5 %) and ‘critical’ (3,0%) alarm states
• Internal audible alarm is 85 dBA at 30 cm
• Long life infra-red carbon dioxide sensors provide 10 years of operation (normal use)
• Simple & secure connections to repeater modules using a prewired plug in connector (up to a maximum of 100 m)
• Suitable for use in high magnetic fields

The QFM440 monitor may be used as a stand-alone device with its own audible and visual alarms, or linked to other repeater modules to mimic the condition of the monitor.
