Telus Convention Centre is a large convention centre located at 136 8 Ave SE in Downtown Calgary, Alberta. This building commonly holds galas and expos. During the COVID-19 pandemic, the centre was used as a mass vaccination clinic, the largest in Alberta. The centre has two buildings. The South Building was opened in 1974, and the North Building opened its doors in 2000. The building was fully renovated in 2000, and the fire alarm system was fully upgraded that year. The most recent upgrade was a panel replacement in 2023.

System Specifications (2000-present)

FACP

The buildings are protected by an Edwards EST4 addressable fire alarm system. The system is networked; the main FACP is located in the parkade boiler room, with a subpanel in the main entrance vestibule. The system runs Edwards' Signature addressable protocol, and is configured for two-stage operation. The system is configured for two-stage operation, however the messages and/or tones are unknown at this time. These panels were installed in 2023, replacing Edwards EST3 panels.

Known Activations

At 8:15 PM on Saturday, October 1, 2022, the system was activated. The cause of the alarm was found to have been a pull station in the parkade falsely activated by a homeless person. The system activation was filmed by TwentyThree33, who entered the building with permission from the Calgary Fire Department.
