Fire Alarms in Buildings (2.0)

I don’t remember exactly but I believe these are the annunciator’s labels (exact order is unknown):

• 1st Floor
• 2nd floor
• Duct Detector
• Sprinkler Flow

These photos are from the Pepsi All Seasons Arena, which is located directly next to where my district’s old high school was. Here is the system’s description:

All Seasons Arena

Original System (In service from the early-mid 90’s-current (the building’s only ever system)):

Panel: Most Likely a Cerberus Pyrotronics SXL

Notification Appliances: All of the original notification appliances were Cerberus Pyrotronics rebranded Faraday 6226-W mechanical horn/strobes. The system was expanded not long after it was originally installed with Siemens U-HN-MCS horn/strobes and U-MCS remote strobes for better coverage in the locker rooms, restrooms, and athletic training room (not 100% sure on the candela ratings). At one point around the same time, a 6226-W in the athletic training room got replaced with an Edwards Integrity horn/strobe (during the short time period in the 90s when the school district worked with Edwards). Recently (within the past 1-2 years), a few older devices have been replaced with Siemens ZH-MC-R horn/strobes.

Pull Stations: Cerberus Pyrotronics MS-51 Pull Stations

Detectors: Unknown Cerberus Pyrotronics duct detectors that use heads that look similar to PE-3s and possibly a PE-3 or similar in the panel room

Annunciator: Cerberus Pyrotronics LED-8

The system hasn’t really changed since I wrote that description around a year ago, but the Cerberus Pyrotronics MS-51 pull station in the lobby did get replaced with a new Siemens MS-151 pull station at some point in the last 1 1/2 years since I’ve been in this building. If you’re not familiar with that model number, it’s one of these:

I was surprised to learn that they are still making these, and that my local Siemens dealer still stocks up on them.
