(2)Articles 6.9.3.3. and 6.9.3.4. apply to every building.
(1)A carbon monoxide alarm shall be installed in a suite of residential occupancy or care occupancy where
- (a) a fuel-burning appliance or a flue is installed in the suite,
- (b) a forced-air fuel-burning appliance provides heated air directly to the suite,
- (c) a fuel-burning appliance or a flue is located in a room, suite or area that shares a common wall or floor or ceiling assembly with the suite, or
- (d) a storage garage shares a common wall or floor or ceiling assembly with the suite.
(2)Where a carbon monoxide alarm is required by Sentence (1) to be installed in a suite of residential occupancy or care occupancy, other than a suite that consists of a combined living and sleeping area, a carbon monoxide alarm shall be installed
- (a) adjacent to each sleeping room in the suite, and
- (b) on each storey without a sleeping room in the suite.
(3)Where a carbon monoxide alarm is required by Sentence (1) to be installed in a suite of residential occupancy or care occupancy that consists of a combined living and sleeping area, a carbon monoxide alarm shall be installed in the combined living and sleeping area.
(4)In addition to the carbon monoxide alarms required to be installed in a suite of residential occupancy or care occupancy in accordance with Sentence (2), a carbon monoxide alarm shall be installed in each sleeping room within the suite where the sleeping room
- (a) contains a fuel-burning appliance or a flue, or
- (b) shares a common wall or floor or ceiling assembly with
- (i) a room, suite or area that is located outside the suite and contains a fuel-burning appliance or a flue, or
- (ii) a storage garage.
(5)Carbon monoxide alarms shall be installed in public corridors serving suites of residential occupancy where the corridor is directly heated by a forced-air fuel-burning appliance.
(6)Where carbon monoxide alarms are required by Sentence (5) to be installed in a public corridor, the carbon monoxide alarms shall be installed such that
- (a) there is at least one carbon monoxide alarm in each portion of a divided corridor, and
- (b) each carbon monoxide alarm in an undivided portion of a corridor is spaced not more than 25 m apart.
(1)A carbon monoxide alarm shall be installed in service rooms or other areas of a building where the service room or other area
- (a) contains a fuel-burning appliance used for building services or laundry drying equipment, and
- (b) is not located within a suite of residential occupancy.
(1)The carbon monoxide alarms required by Articles 6.9.3.2. and 6.9.3.3. shall
- (a) except as permitted in Sentence (2), be permanently connected to an electrical circuit and shall have no disconnect switch between the overcurrent device and the carbon monoxide alarm,
- (b) in case the regular power supply to the carbon monoxide alarm is interrupted, be provided with a battery as an alternative power source that can continue to provide power to the carbon monoxide alarm for a period of not less than 8 h in the standby condition, followed by the operation of the carbon monoxide alarm for an alarm signal for at least 12 h,
- (c) be wired so that
- (i) activation of one carbon monoxide alarm within a suite of residential occupancy will activate all carbon monoxide alarms within the suite, and
- (ii) activation of one carbon monoxide alarm located in a public corridor serving suites of residential occupancy will activate all carbon monoxide alarms within the corridor,
- (d) be audible within sleeping rooms when the intervening doors are closed, where located adjacent to a sleeping room in a suite of residential occupancy, and
