Fire Alarm Test 120 | Old Simplex 4903s
Pretty cool system for this one. This is one of the last simplex systems left in this school district. The only ones are this building, the 4020 building I uploaded a few weeks ago, and a 4002 system (Stay Tuned). This was originally a simplex 4002 panel however it was replaced with a 4007es panel when the building was added on to. They left all of the original devices intact, and the addition has ceiling mount truealerts.
