Information
Table of contents
13.1 Alarm systems
13.1.1 Single-stage system
A single-stage system is designed so that, when activated, the alarm signal shall be immediately transmitted throughout the building to warn the occupants that an emergency exists.
13.1.2 Two-stage system
In a two-stage alarm system, a distinct alert signal shall first advise of the emergency.
Note: A two-stage system is used in facilities where the immediate evacuation of the occupants is neither desired nor practical.
The second notification in the two-stage alarm system will advise occupants on how to proceed.
Both single stage and two stage systems cause the fire alarm panel to send signals to the fire department or monitoring station (fire alarm receiving centre or 9-1-1 Centre).
Alarm signals to evacuate occupants do not sound. Notification is via a voice announcement.
Technical requirements for fire alarm systems are provided in the NFC.
13.1.3 Where a fire alarm system is provided
Where a fire alarm system is provided, the visible SIGNAL system shall consist of strobe lights conforming to CAN/ULC-S526 that are designed to operate as part of the fire alarm system.
13.1.4 Where a fire alarm system is not provided
Where a fire alarm system is not provided, the visible SIGNAL system shall consist of strobe lights conforming to CAN/ULC-S526.
13.1.4.1 Emergency communication formats
Building managers shall ensure communication systems that can alert all building occupants are in place in the event of an emergency.
Note 1: Clear and efficient communication with everyone, including regular occupants and visitors, will enhance the safety of all building users during an emergency.
All building occupants shall:
- receive emergency egress information in the format of their choice; and
- discuss format choices during the preparation of an individual’s personal emergency egress plan.
Some building occupants may need information in various formats, including:
- large print;
- electronic messaging;
- speech synthesizers;
- an electronic pager; or
- sign language interpretation.
Note 2: Using a video relay service in an emergency is not acceptable as it can be time-consuming.
13.2 Emergency notification systems
13.2.1 Alerting or signaling devices
There are a variety of signaling devices available that provide either visible, audible or tactile cues to signal an alarm. Information on alerting devices and emergency alerting systems in Canada is provided in Annex C.
Lower frequency audible alarms should be provided for people who are hard of hearing.
Note: They are particularly effective when the building occupant is asleep. Also available for people sleeping are assistive technologies that provide alerts by a flashing light and/or a pillow vibrating device placed under the pillow when triggered by a fire or smoke alarm.
13.2.2 Visible device location
Visible signal devices (strobes) shall be connected to a power source and emit a strobe light. The signal shall be provided in both public and private areas of a building.
Visible signal devices shall be;
- located in conformance with the installation requirements for visible signal devices in CAN/ULC-S524.
13.2.3 Smart phones
Communication tools such as smart phones or mobile phones are increasingly being used by everyone. They are an excellent form of communication as they can receive audio and tactile alerts to notify of an incoming message and can be used in text and voice (audible) formats.
Alert signals shall be transmitted via the National Public Alert System by all telecommunications providers. See Annex C for information on national and provincial alert systems.
13.3 Emergency telephones

All public announcements relating to emergency egress shall be provided in a variety of formats, including:
- audible announcements;
- broadcasting to hearing technologies and implantable devices;
- visual announcements; and
- electronic announcements.
Note: Variable message boards should also be used.
When provided, variable message boards shall:
- not use pre-recorded messages for emergency information;
- utilize a well-contrasted characters (avoiding red and green or blue on a black background);
- be mounted at a maximum height of 1500 mm; and
