Did you ever post this system out in the "What alarm do you have at work/school" for this building and the other buildings on the campus because it does seem very interesting.
I posted a preliminary version in "Fire Alarms in Buildings 2.0" eons ago, but I'll go ahead and restate it here in its complete form. My first aforementioned post was not complete, as I had not been through the entire building then.
The main panel is a Simplex 4005 installed in 2002-2003 during a major auditorium renovation, which is replacing a 4207 installed during a 1976 renovation//upgrade and a Fire-Lite MS-5210UD (cabinets for both still intact but gutted; forgot to mention this in the previous post) installed during a 1997-1998 expansion (building was built in 1922). 8 zones are in use and the 4005 is installed in the main boiler/electrical room on the ground floor. There is a Simplex 4602-9102 RCU LED annunciator in the main vestibule. Signal coding is Temporal 3 across the board, generated by the 4005.
Initiating devices from the 1976 portion of the system are Simplex 4251-20 pull stations. The practice rooms and storage spaces were fitted with System Sensor 2100 smoke sensors in the 1990s when the Fire-Lite panel went in. The 1997-98 expansion has Simplex 2099-9754 pulls (replacing the original Fire-Lite BG-10s) and System Sensor 2100 smoke sensors. At least 5 smokes (that I know of) have been replaced with Simplex 4098-9601 conventional TrueAlarm sensors.
Notification appliances from the 1976 portion are Simplex 4051 horns on trim plates. A couple of them are surface mounted on red backboxes, and there are no visual signals in this portion. The 1997 expansion and 2003-renovated section have System Sensor MASS-ADA horn/strobes (800 Hz). The restrooms in the 1997 portion have System Sensor SS-241575-ADA strobes. The 2003 restrooms have SpectrAlert Classic SC241575 remote ceiling strobes. Two 4051 horns have now been replaced with Wheelock MT-1224R horns (high volume horn). The large rehearsal room on the ground floor has a Wheelock AS-241575-FR horn/strobe (high volume) and the choir room, also on the ground floor, now has a Wheelock MT-24MCW-FR horn/strobe.
