I run the website http://firealarmstore.com FireAlarmStore.com, and sell a lot of different new and used fire alarm components. So first of all, I’m always interested in purchasing equipment, so would it be possible to get a list of what you have for sale?
As for selling alarms on eBay, especially used equipment, buyers like to see good pictures of what’s for sale, that it’s been tested, and that they can return it if it doesn’t work.
