Jardine Hall these days has a Simplex 4010 powered system with TrueAlerts and 4099s, but there are remains of the old system from the 1960s to 1970s.
Like this TrueAlert remote strobe on the remains of a 4050-85 light plate.
And this 4090-1 fire bell.
Just something I thought to be a nice little relic of the past.
