I have a 4500EF and 4500EM. The alarm light and audio are connected on the EF unit. I currently have 2 switched inputs (UAT FAIL, MAIN ALT FAIL) connected to the EM unit. There is a possibility I may also add switched inputs to the EF unit as well.

Questions:
1) Do switched inputs trigger the alarm light?

2) if so, will I have to connect pin 14 on both the EF and EM units to the alarm light since switched inputs are not transferred between units?

3) As far as audio, only switched inputs on the unit that is connected to the audio panel will have audio?

Thanks
