C-tec produce a variety of 800 compatible nurse call systems, which model are you actually using here?

They have different connections for different models.
You do have the sounders connected in parallel not series don't you?
 
I have posted the instructions for you, and explained the switched and line driven sounds......So what do you want this system to do which has not been explained
 
I changed the wiring from sdr - and + to using one of the com.

Sounder(s) get 14v but there is the slightest noise from them.

Sounders have an in and an out.
 
Are the sounders C-tec 800 series.....C-tec have two on the market....800 series standard zone and Quantec addressable 2 wire. can you give me the part number for the ssounders you have

The sounders do not appear to have a part number, they merely have sounder or something written on the front and a 2 pole in and out on the rear.

They have an adjustable volume.

The terminals have seen better days, so im hoping to rewire from the first to the second sounder and replace them, and hope that this would sort it out?
