Fire alarm annunciator

Hey guys, I found a Faraday RDC 800 on eBay for $40 and I feel like this is a good deal. Is the annunciator a good first annunciator?

Do you have a compatible Faraday panel? You can’t use an annunciator by itself.

No, I thought you could use it by itself

You can’t.

At least you asked first…

Could you operate it with a Silent Knight Sk-4?

Silent Knight and Faraday are not owned by the same company, so it would be unlikely that they would work. Plus, the datasheet says it is only compatible with the Faraday MPC-2000 FACP.


If you have not bought it then it’s a good thing you asked here first. A lot of collectors buy stuff thinking they can use it without confirming first.
