It is OK to bump topics but in the future you should have something to add to it other than just saying you are bumping it. :)

My Current school has a Telecor XL bell and intercom with a Mitel IP paging unit bridge and a Telecor MCC-4.
The Clocks are controlled by a Standard 1463. Both in the Front office. School was Built in 1998

My old school has a Simplex 5120 bell and intercom with a Mitel IP paging unit bridge and no intercom console (They just used the Mitel IP Phones). It is in the LMC (School is Open Concept)(LMC in the center of the 'Learning Center'
The Clocks are controlled by a Simplex 6400 Master Clock. It is in the Art Room (Old Office) (Office and Art Room were switched in 2012 due to security) That school was built in 1975

1st ES - I have no clue about what kind of bell system they had, but it used vibrating bells, I think 6" ones behind grilles. They were definitely loud though. They were probably either Edwards or Simplex, and they rang for either 3 or 5 seconds. The school was built in the mid-70s and had a more open architecture; the classrooms were open to the hallway and the walls were movable. I've never seen that kind of setup anywhere else. Therefore, I don't think they had a clock system. I'm not sure about the PA system.

2nd ES - Simplex clocks and time system with tones over the PA system (which was most likely Simplex, since the fire alarms were also Simplex). The class tone only rang when school started and ended. The tone was a 500 Hz chime with 3 dings that lasted about 1.5 to 2 seconds, and then a ding that was cut off after about a half-second. The announcement tone was about 700 Hz (not sure of the exact frequency, but it was an F note) and lasted either .5 or 1 second.

MS - the middle school used to be 2 separate schools, but they were connected around 1970. Some of the rooms had Standard clock/speaker units, and the rest of them had separate clocks and speakers. They originally used bells - half of the school had grey IBM 6" bells, and the other half had black Autocall bells, mostly 4" but some were 6". Actually, there was one tan 8" bell like the one in SimplexTech's vid when he was testing that old IBM/Simplex system. When I went there, they had a class tone over the PA that sounded the same as my ES except there were 4 dings. The clock system was most likely Standard, but I'm not sure about the PA system. The announcement tone was a half-second 500 Hz tone, but it sounded a bit buzzier than the class tone. Half of that building was renovated in '99, and I don't know what companies they use now.

HS - the original high school had Edwards clock/speaker/phone units, and I think the bell system was Edwards. They had Edwards 4" adaptabels, and buzzers in the rooms, behind the clocks. They rang for 3 seconds. I thought the bells were loud, but not as loud as my first ES. Some of the buzzers didn't sound though. A few of the ones that did were loud, and others were quiet. That school was renovated in 2000, and they now have Simplex clock/speaker units, and they use the exact same tones that my second ES uses. I'm pretty sure their time system is Simplex. The PA might be Simplex also.
Open Concept- kind of a 70s concept that didn't quite work

I am now working at my old elementary school in the office and it is very exciting and fun for me and I still am able to recognize some of my old teachers and they recognize me. The school was completely renovated which happened when it changed from a K–6 school to a PK–5 school so its all new. Almost like a new building. Anyway they said they have a new bell but in the office I can't here it go off. I assume they are in the classrooms.

So I realized that there is a bell but the bell is only used for a warning bell and a late bell. I am still not sure what kind it is but its a tone generator and it sounds kind of like a xylophone. As far as I know, it only goes off twice. Maybe a third time for dismissal.

I was in private schooling until freshmen year and we didn’t have bells.

I should explain my high school has 2 buildings. Each has a separate bell PA system. The PA parts of the systems are linked from one to the other but not the other way round.

Freshmen year the main campus had an unknown bell system with a bell tone that sounded like a clearer version of the telecor 580 HZ. And a 1 time a day bell that sounded like a doorbell for the first shuttle between the buildings. Over the summer of 2018 this system was replaced with a telecor XL which I will talk about in a moment.

The South Wing has only had a telecor XL in my time at this school. My freshmen and sophomore years there was only the 580hz tone for 2 seconds for all bells. This year the shuttle bells are 200 HZ pulse 6 times.


From the 2018-2019 school year the main campus has a telecor xl. Most bells are 580 Hz 3 seconds. The 9:19 shuttle and 5:25 sports buses are 5 seconds of 300hz pulsed. And the 3:55 after school buses are unknown, I will find the video I have.


Pa can be made from main campus to both buildings, but only to south wing from south wing
For example my first class is in the south wing and one day Main campus had an active fire alarm (faulty sensor) when our principal made the pa to enter the main campus we got it at south wing even though we were still in class. But when I did a special PA at south wing at the request of the 9th grade assistant principal it was only sent out there and not both buildings.

My assumption that it was an older version Telecor system possibly? My last year of high school I did morning announcements and such, so I got to know the PA systems very well. In fact, I ended up writing a directory of each room and each PA inside it, as well as a programming guide for the secretaries to use once I left, as I was the one programming the schedules in. Anyways, the system was a Telecor 2, from the mid 80s. Here's a video of me using it. Sometime in December of said school year the system fried, and was temporarily replaced. During March break, they replaced the old Telecor 2 with the new Telecor XL. Funny thing about the two is there's really no difference, besides a few programming features and updated equipment. The tones were the exact same, as we used the same tone from the old system.
