Seeking assistance on a Simplex 2350 Master Clock regarding the duration of the sounding of the bell to announce the change of class. The school suffered a power failure resulting in the resetting of the clocks and impacting the duration of the sounding of the bells. Prior to the outage, the bells annunciated for 5-6 seconds and now is reduced to one second. On reviewing the Operator's Manual, I am not able to identify a section or instructions mentioning increasing/decreasing the duration of the bells sounding. If anyone has instructions on increasing the bell notification, it would be greatly appreciated.

Thank you

Would either of you happen to have the User's Manual for the Simplex 2350? I have been looking for it for a while and it doesn't seem to exist anywhere on the internet.

The 2400 and the 2350 are the same instructions there was no seperate instructions for the 2400, it was just a bigger system. Maybe someone can put these 2 post together and add them to the instruction list.

Thanks, Jim. I've copied your post to our Simplex sticky for future reference.

The scans of the instructions for the 2350/2400 are VERY helpful, but our techs are now saying that they need a list of codes from "Appendix A" to complete their task. Does anyone have these pages?
