Let’s start a topic about systems that seem overkill for the environment they’re in. For example, a highway rest stop with a Simplex 4100ES, or a gas station with voice evac.
I’ll start: I went to a Longhorn Steakhouse in Sarasota, FL with an NFS-640 voice evac system, with SpectrAlert Advance speaker/strobes. I’ve also seen this at another restaurant in Chantilly, VA, but the name escapes me at the moment.
It’s an interesting coincidence that you mentioned a rest stop with a 4100 as an example—this is the first system I thought of. Certain ONroute rest stops along Highway 401 in Ontario have 4100U panels with InfoAlarm displays:
These systems are also unusual due to their use of separate horns and strobes:
Similarly, a tiny three-storey building at my university has a 4100ES with TrueAlert speaker/strobes. The first floor of the building is occupied by a small restaurant, while the upper floors house offices and meeting areas.
