Hi I was wondering does any one know what model of black horn sounder was used in the 80s and early 90s because I am trying to add a horn type sounder in my now dummy bell box and the company is something like king lee burglar alarms and it was installed in 1990. I have the cover already off the main sounder but can't reach with a ladder to put it back on or can't read the sounder brand. Is there any alarm installers when the vented boxes were made and would you know where I can buy the sounder for my rear bell box, I have a picture but ill upload it later where you can see what the sounder looks like not to get confused with the lynteck tk814 but it looks similar to that.[/img]
