Cochrane High School is a large high school located at 529 4th Ave N, Cochrane, Alberta, Canada. The school opened in 1962, and expanded several times: 1966, 1970, 1972, 1985, with a second floor being added in 1991, and finally a modernization in 1996. Portables were installed in 1990 and 1992. The fire alarm system had an upgrade in 2015.
System Specifications (1991-present)
FACP
The building is protected by an Edwards EST3 hybrid-addressable fire alarm system. The panel is located in an electrical room. The system runs EST’s Signature addressable protocol, and the system coding is likely temporal.
The panel replaced an Edwards Custom 6500 in 2015, and the system was upgraded to mostly addressable.
Annunciators
There is an Edwards EST 3-LCDXL1 LCD annunciator at the entrance.
Notification Appliances
All notification appliances except for one are Edwards 439D-6AWC vibrating bells (6” gong), installed in 1985 and 1991 depending on the area; these are also in the portables.
Approximately 70% of bells are mounted on Edwards 403-5A-R strobe plates (15cd), which were added in 1996. The remaining bells are mostly installed remotely, most behind metal grills.
There is an Edwards 439D-10AWC vibrating bell (10” gong) located in a small hallway leading to the gymnasium.
For outdoor notification, there are Edwards 439D-6AWC bells located on each side.
Initiating Devices
Pull Stations
All pull stations are EST SIGA-270 addressable single-action pull stations.
The portables still have their Edwards 270-SPO conventional pull stations.
Automatic Detection Devices
There are EST SIGA2-PS addressable photoelectric smoke detectors throughout the building.
There are a few Edwards SIGA-SD addressable photoelectric smoke detectors, installed as deficiency replacements. All smoke detectors are mounted on SIGA-SB bases.
There are also Edwards EC20RRU-3 rate-of-rise heat detectors in the portables, installed in 2020 replacing Edwards 281C heat detectors after being recalled.
The art room and south facing wall of the library are also protected by a sprinkler system, added in 1985.
Modules
There are EST SIGA-CT1 addressable monitor modules supervising the south facing wall of the library and art room's sprinkler system's tamper and flow switches.
