(1) Except as provided in Sentence (2), a firewall having a fire-resistance rating of
at least 2 h and separating 2 existing buildings may serve as the firewall for which the
Code requires a fire-resistance rating of more than 2 h if there is no extension in height.
(2) Where the alteration consists in a change of occupancy thus creating a new
Group F, Division 1 or 2 occupancy, the fire-resistance rating of the firewall section in the
altered part of the building must be increased to 4 h.”;
by replacing Article 10.2.1.1 of the Code by the following:
“10.2.1.1. Scope. This section applies to any building constructed before December 1,
1976, whose height is more than 22.85 m and whose distance between grade and the floor
of the last storey is more than 18 m.”;
by deleting Sentence 10.2.2.6.(2) of the Code.
43. Section IV of that by-law is amended by adding the following before Article 104:
“103.1. Schedule A to the Code is amended by adding the following articles after Article A3.2.4.17:
“A-3.2.4.19.(1) Alert and Alarm Signals. Alert signals are part of a 2 stage fire
alarm system. The intent of the first, alert, stage is to notify persons in
authority of a potential threat to building occupants. If a continuously staffed
location is available, the alert signal can be restricted to that location.
A-3.2.4.19.(2) Alarm Signal Temporal Pattern. The temporal pattern of an
97-068 / 22
alarm signal relates to the time during which the signal is produced and the
intervals between the individual signal pulses. The international standard ISO
8201, “Acoustics - Audible emergency evacuation signal,” includes a pattern
that is becoming widely used in different countries and it is appropriate for
this pattern to be adopted in Canada. The temporal pattern can be produced
on most signalling devices. Most existing fire alarm systems can be modified,
and this pattern could be phased in when the systems require modification.
The characteristic of the pattern is a 3-pulse phase followed by an off phase.
The 3 pulses each consist of an on phase lasting for 0.5 ± 0.05 s followed by
an off phase lasting for 0.5 ± 0.05 s sounded for 3 successive on periods and
then followed by an off phase lasting for 1.5 ± 0.15 s. Figure A-3.2.4.19.(2).A.
indicates the pattern that is intended.
Figure A-3.2.4.19.(2).A.
Temporal pattern for fire alarm signal
Although the diagram shows a square wave form, the wave can have other
shapes that produce a similar effect.
If single stroke bells are to be used, the temporal pattern can be produced by
having the bell struck three times at a rate of one stroke per second followed
by an interval of 2 s of silence. Figure A-3.2.4.19.(2).B. shows the pattern that
results.

A-3.2.4.19.(4) Sound Pressure Level. For the purposes of this requirement, an
audible signalling device should not produce a sound pressure level more
than 95 dBA when measured at a distance of 3 m from each device or at a
height of 2 m above the floor.
A-3.2.4.19.(5) Residential Sound Level. In a building in which corridors or
hallways serve more than one suite or dwelling unit, there will be situations
where an audible signal device cannot be placed in the corridor or hallway to
alert persons sleeping in suites and dwelling units, because the sound level in
the vicinity of the device would exceed that permitted by Sentence
3.2.4.19.(4). In these situations it will be necessary to supplement the building
fire alarm system with an audible signal device in the suite or dwelling unit.
These devices could be piezoelectric devices similar to the sounding units in
many smoke alarms, subject to the device emitting the appropriate temporal
pattern required by Sentence 3.2.4.19.(2).
A-3.2.4.19.(9) Disconnect Device for Dwelling Units. To minimize the
annoyance caused by false and unwanted alarms, the disconnect will permit a
person to silence the local audible device within the dwelling unit. At that time
the person would be aware of sounds from devices in common spaces and
could plan appropriate action. The disconnect will reduce the possibility of
tampering with the audible devices.”.”.
44. Article 104 of that by-law is amended by replacing, in the title of Article A.3.2.5.10.8(c) and 8(d), the
words “Standpipe Systems and Hose Stations” by the words “Piping Systems”.
45. Article 107 of that by-law is amended:
(1)
(2)
by deleting, in paragraph 2, the word “alter,”;
by replacing paragraphs 3 to 9 by the following:
“(3) alter a building, as well as install or change any appliance or equipment covered by
a requirement under this by-law or the Code, in particular:
(a) a standpipe and hose system, a fire alarm system and an automatic
sprinkler system;
(b) a solid-fuel-burning appliance and an oil combustion appliance;
(c) an appliance intended for the storage of flammable substances,
combustible liquids and all other materials that may constitute a safety
hazard for the occupants of a building and the public;
(d) electromagnetic locks and generators;
(e) heating and air-conditioning systems serving more than one suite and
having a capacity of more than 560 L/S, and ventilating systems;
(f) smoke control or smoke venting systems;
(4) construct or extend a parking area;
(5) upgrade existing buildings referred to in Part 10 of the Code.”.
46. Article 123 of that by-law is amended by adding, after the word “owner”, the words “, contractor or any
97-068 / 24
other interested person”.
47. Article 136 of that by-law is amended by deleting paragraph 2 of the second paragraph.
48. The By-law concerning the ventilation of buildings in the city of Montréal (4936) is repealed.
