Fire Alarms at the Boston Prudential Center/Copley Square Plaza (One building was constructed in 1983 and the other in 1993)
Simplex 4903-9105+Various speakers
Simplex 2902 Speakers
Gentex GXS-4-HWR (same strobe as 4903-9105)
Simplex 4903-9357 (75CD), there were a bunch of these early 2000’s speaker strobes installed in one section
Simplex 4903-9358 (110CD)
Simplex 4903-9359 (15CD)
Simplex 4903-9146 (15CD, later model)
Simplex 4903-9144/4903-9149 (110CD, most of the 4903 speaker strobes were only 15CD, unfortunately, I was hoping for 30 and 110CD models, there were several of these things mounted on the ceiling, which is not a fail because the wall and ceiling 4903s/4904s use the same lenses!)
Simplex 4903-9147 (15CD, later model, there was a bunch of these installed in one section)
Simplex 4906-9151 (Multi CD, set at 110CD)

EST Genesis Speaker strobes (Both wall and ceiling)
Space Age VA4/A32 strobe plates with speakers attached to them (I love Space Age!)
Space Age AV34 Light Plate (Very chunky size, but lovely!)
System Sensor SpectrAlert Advance Weatherproof Remote strobes (Not shown)
Wheelock AS Horn strobes in a Star Market Grocery store nearby (Not Simplex!)
There’s probably many more models I missed; correct me if I’m wrong; there could’ve been some Simplex QuickAlert or 4904 remote strobes installed too as well as other EST speaker strobes. Love the variety here!
