Fire Alarms in Buildings (2.0)

I rarely see new Simplex pulls used with 4051+4050-80s. Only time I did was at the Davis K-8 school; a couple of the old 4251-30 pulls were replaced with new Simplex 2099-9103s early this year.

But I DO tend to see newer Simplex alarms with old Simplex pulls though.

I know, that’s why I bet this is an adressable system. They probably upgraded the pulls to addressable, but haven’t gotten to the alarms yet.

I remember once at a rest stop I saw 4251-20s (looked like they were probably 70s) and 4903 horn/strobes.
