Important Warning Statements

This product is intended for use in ordinary indoor locations of 
family living units. It is not designed to measure compliance with 
Occupational Safety and the Health & Safety Executive (HSE).

The installation of this device should not be used as a substitute 
for proper installation, use and maintenance of fuel burning 
appliances, including appropriate ventilation and exhaust sys-
tems. It does not prevent CO from occurring, nor can it solve and 
existing CO problem.

WARNING: This device is designed to protect individuals from 
acute effects of carbon monoxide exposure. It may not prevent 
the chronic effects of carbon monoxide exposure. It may not fully 
safeguard individuals with specific medical conditions. If in doubt, 
consult a medical practitioner.

Individuals with medical problems may consider using warning 
devices which provide audible and visual signals for carbon mon-
oxide concentrations under 30 PPM.

This carbon monoxide alarm requires a continuous supply of elec-
trical power – it will not work without power.
