(3) If a fire alarm system is installed in a building, an automatic sprinkler system shall be electrically supervised to indicate a supervisory signal on the building fire alarm system annunciator for each of the following, (a) movement of a valve handle that controls the supply of water to sprinklers, (b) loss of excess water pressure required to prevent false alarms in a wet pipe system, (c) loss of air pressure in a dry pipe system, (d) loss of air pressure in a pressure tank, (e) a significant change in water level in any water storage container used for firefighting purposes, (f) loss of power to any automatically starting fire pump, and (g) a temperature approaching the freezing point in any dry pipe valve enclosure or water storage container used for firefighting purposes. (4) If a fire alarm system is installed in a building, a fire pump shall be electrically supervised in accordance with NFPA 20, “Installation of Stationary Pumps for Fire Protection”. (5) If a fire alarm system is required in a building, electrical supervision shall be provided to indicate, on the fire alarm system annunciator, a loss of power to a heat tracing cable that is installed to heat, (a) a standpipe riser, (b) a sprinkler line as part of a fire suppression system, or (c) an exit or means of egress to keep it free of ice and snow. (6) In a building regulated by the provisions of Subsection 3.2.6., the indication of a supervisory signal in accordance with Sentence (3) shall be transmitted to a proprietary control centre or to an independent central station.

(1). (2) Except as permitted by Sentence (6), the annunciator required by Sentence (1) shall have separate zone indication of the actuation of the alarm initiating devices in each, (a) floor area so that in a building that is not sprinklered, the area of coverage for each zone is neither more than, (i) 1 storey, nor (ii) 2 000 m2, (b) floor area so that in a building that is sprinklered, the area of coverage for each zone is neither more than, (i) 1 storey, nor (ii) the system area limits as specified in NFPA 13, “Installation of Sprinkler Systems”, (c) shaft required to be equipped with fire detectors, (d) air handling system required to be equipped with smoke detectors, (e) fire extinguishing system required by NFPA 96, “Ventilation Control and Fire Protection of Commercial Cooking Operations”, (f) contained use area, (g) impeded egress zone, (h) fire compartment required by Sentence 3.3.3.5. (2) or Sentence 3.3.4.11. (2), and (i )fire compartment required to be separated by vertical fire separations having a fire-resistance rating not less than 2 h, other than dwelling units described in Subsection 3.3.4. (3) An annunciator need not be provided for a fire alarm system if not more than one zone indicator is required in Sentence (2). (4) If an annunciator is not installed as part of a fire alarm system in conformance with Sentence (1), a visual and audible trouble signal device shall be provided inside the main entrance of the building. (5) The requirements in Sentence (1) are waived in a building, (a) Reserved (b) that has an aggregate area for all storeys of not more than 2 000 m2, and (c) that is not more than 3 storeys in building height. (6) The area limits of Clause (2)(a) are waived for an interior undivided open space used as an arena, a rink or a swimming pool provided that other spaces in the building that are separated from the open space are individually zoned in accordance with the requirements of Sentence (2). (7) A fire alarm control unit installed in close proximity to a building entrance that faces a street or an access route for fire department vehicles that complies with Sentence 3.2.5.5. (1), is deemed to satisfy the requirement for an annunciator provided all indicators required for an annunciator or trouble signal device are included on the control unit. (8) In a building containing a hotel in which a trouble signal sounding device has a silencing switch, a trouble light shall be installed in, (a) the main reception area serving the hotel, or (b) another continually-supervised location. (9) In a long-term care home, a remote audiovisual fire alarm trouble signal shall be located at the main nursing station.
