I recent got a job at a start up company as a systems admin, and knew that I would be programming phones but did not expect to be getting involved with the loudspeaker system. I am not a telecom person so I need some help

We have a bogen PCM2000 loudspeaker system, and executives want to have a buzzer for shift changes, breaks, and lunches. Total of 15 per day. If we add a Talk-back-module we can get 8. So maybe 2 modules? still waiting on the vendor for that..

Since its a startup company they are very tight on money. I was researching if we could use a "Background Music" input to do this. We have electrical engineers on site that said they could rig a timer with a tone output if I can find a way to interface it with the loudspeaker.

Could this be an easier shortcut? I was looking at #2 on this link: https://www.bogen.com/support/drawings/pdfs/PCM2000_Bkgd_Music.pdf

and it looked like it would be pretty simple to wire our timer, and instead of putting it to a speaker, put it to the Background music source.

Sound about right?

That sounds like it would work. Viking makes a timer/tone unit that would work for you.
CTG-1

The PCM2000 seems to have an input for sending a tone to designated speakers. Short EM/SC to GND at the appropriate time and a tone of your choice goes to the zone(s) of your choice.

The Viking CTG-1 will work for you as the time base, as it has 2 contact closures you could use to trigger the Bogen. But really any time clock that can be programmed for certain times of day with a contact closure will work.

The programming of the Bogen is done using a telephone you connect to it, or through your telephone system if the two are connected together.

All of the manuals for hookup and programming are online.

In a nutshell, it sounds like you can do this with existing equipment except for the time clock, which you could buy or as you have mentioned, have an on-site engineer build for you.

Thanks, guys. I was even looking at taking a audio out from a PC and wiring it in with a timed task more or less as a trial..

I'm not sure what you mean by a contact closure, but I have to go chase down our electrical guy.

The bogen is tied into our phone system. I need to skim through the manuals on how to program it.

If you want to go down the software route then there are various free/paid for 'school bell' or 'church bell' ringing programmes that will play sound files at specific times/days. Having the capability for speech enables 'message of the day' to be broadcast to employees, eg health and safety reminders.

A 'contact closure' is just a switch/relay as your paging system may need a push-to-talk switch operated.

If you don't know what a contact closure is your in over your head.

Actually, since a CTG-1 is an audio device, contact closures are only for the override tones.

Wiring a CTG-1 is pretty straightforward and programming is fairly clear.

I second the CTG-1. I've used them in the past and they work well and are easy to program.

How do I physically connect the PCM2000 to the CTG-1?
I just want use the CTG-1 as the master clock sync device for the Bogen PCM2000/PCM-TIM.

I know this thread is old, but I am now faced with the same situation, only in a school setting. @Madlife, did you ever get this device to work? If so, how did you connect to the Bogen unit?

Thanks.

Madlife has only posted twice in this forum and hasn't been seen since, So I wouldn't expect a reply.

This tread is OLD as you have noted. It is better to make a fresh post than tagging on to the outdated.
