CF Market Mall is a large mall in Calgary, AB. It is located at 3625 Shaganappi Trail NW, near the neighbourhood of Varsity. It is a one-level shopping centre, with the anchor stores being Hudson’s Bay (which is two floors), Sport Chek, Safeway, among others. The mall is owned by Cadillac Fairview. It was built in 1971, and had expansions in 1988, and again in 2004. The fire alarm system was installed following the 2004 expansion.
System Specifications
FACP
The mall is protected by a networked Edwards EST3 hybrid-addressable fire alarm system. There are several panels, one has been found in the Safeway entrance vestibule, and there is another confirmed panel in the security office. The security office panel has a voice-evacuation mic on it; the system is not equipped with voice-evacuation, but when activated, it silences all the horns but keeps the strobes flashing, and the mic feed goes through the mall’s PA system. The system partially runs EST’s Signature-series protocol, and is configured for two-stage operation. The system coding is 20BPM in first stage (⅘ second blasts), and temporal for general alarm, however the system had a glitch in September 2018 during an alarm condition where the coding flipped to march time for a few seconds. The horns are noticeably out of sync. Prior to 2021, one of the NACs was set to continuous for general alarm. The system has been free of troubles since February 2022.
Annunciators
There are EST 3-LCDANN LCD annunciators located in most entrances.
Notification Appliances
Main Mall Corridors
The notification appliances are EST “Integrity” 757-7A-TW (white, wall-mount, 15/75cd) horn/strobes and 757-1A-TW (white) horns, mounted in a pattern of horn/strobe, horn, horn/strobe, horn. The horn/strobes have the standard wall FIRE orientation, but are on the ceilings. These were installed with the EST3.
Tenants
The tenants mostly contain an EST 757-7A-TW (white, wall-mount, 15/75cd) horn/strobe. Some tenants contain 757-7A-T (red, wall-mount, 15/75cd) horn/strobes. They are mostly mounted on the ceilings, but some have them on the walls. These were installed with the EST3.
Toys R Us
The notification appliances were left untouched during the upgrades in 2004, and are Edwards 882-2B (red) horns. They were installed in 1992 when the store opened.
Safeway
The notification appliances were redone in 2020, most likely for uniform sound. They are EST 757-7A-T (red, wall-mount, 15/75cd) horn/strobes, which replaced System Sensor “SpectrAlert” P241575A (red, wall-mount, 15/75cd) horn/strobes. These were set to continuous electromechanical horn. There is an EST 757-7A-TW on the ceiling in the hallway to the mall, which was the only alarm not replaced.
Exterior
The outdoor notification appliances are mostly EST CS405-7A-T (red, 15/75cd) weatherproof remote strobes, on most sides of the building. In the covered areas, such as the loading docks, there are EST 757-7A-T horn/strobes. One side of the mall has an EST 757-1A-T (red) remote horn. There is an EST CS405-7A-T outside the Safeway, installed in 2020 replacing a System Sensor “SpectrAlert” S1224MCKA (red, wall-mount, multi-candela) weatherproof remote strobe.
Initiating Devices
Pull Stations
The pull stations are mostly EST SIGA-270P addressable two-stage pull stations, installed during the upgrade. Newer variants can be found as deficiency replacements. Near the Toys R Us, there are Edwards 270-GAO conventional two-stage pull stations, installed in 1988. There was one original 270-GAO (classic shield, no FIRE ALARM), but it has been replaced with a SIGA-270P this year. In the Safeway, there are Edwards 270P-SPO conventional two-stage pull stations, installed last year replacing Grinnell MS-402GR two-stage conventional pull stations.
Automatic Detection Devices
Most of the mall is protected by waterflow, however there have been a few EST SIGA-PS addressable photoelectric smoke detectors spotted in open ceilings, on SIGA-SB bases. [[Category:Facilitie]
