Street boxes are usually taken out of service and sold to be re built for service. You can get a bit more than what they go for when you sell it back. They are by all accounts for those that want to collect one rare. They are a true collectors item. as is most gamewell products. You are also contending with just about every current and retired fire fighter that wants one. As for panels you are dealing with sellers who learn of the value or know the value of what it costs to buy new. Folks in the alarm business know if you can sell just the guts to a panel you save the customer a pretty penny in ripping out an entire panel and possibly the notification devices as well as possibly the smokes. As I have always said this stuff is not really a hobby. If we saw a real value in this stuff it would not end up in the dumpster. It’s not really worth a guys time who makes 40-100 dollars an hour or more to list fire alarms for a few bucks here and there.
As far as NOT wanting anything… Just because you have it does not mean you have to turn it on. I highly doubt simply seeing the alarm is going to bring back repressed memories i mean really…
