Relay Switcher

I have a Fire Mimic Panel which has no audible indicator functionality but instead just turns a LED on. What I need is to be able to switch a relay when this LED comes on so I can then use the relay to turn on a sounder. I was wondering if the SKU: CE05114 or even SKU: TA0044 will enable me to do this by wiring off the existing LED on the Mimic Panel circuit board into this relay board module thereby enabling me to use the rely to activate a sounder.

Hi Peter,

This should work fine, I can’t imagine your LED’s are using signals >5V to turn them on and off. With that said, you are well into the DIY zone. If it’s a 240V driven system, then someone qualified to work on it should do any modifications.

Thanks, will give it a go.
