The carbon monoxide detector (which must be capable of emitting a local audible alarm to warn the occupant of an abnormal rise in carbon monoxide levels) becomes compulsory in the event of:

• the presence of an instantaneous water heater fuelled by gas or liquefied hydrocarbons (Annex 2, article CH 34, new § 4 - Special provisions relating to hot water production appliances with an output equal to or less than 8.72 kW) ;
• housing connected to the fuel gas distribution network (Annex 2, article GZ 3, new § 2 - Conformity and implementation of the gas installation in residential buildings; Annex 3, new article HAB 16-2 - Provisions applicable to buildings for residential use, housing for the elderly or disabled).

This local alarm can be supplemented by the simultaneous broadcasting of information to one or more connected devices (smartphone, tablet, etc.).
