Sometime within the last month or so a very useful source of information for enthusiasts and hobbyists went away. Hosted on thefirepanel.com was a Simplex model number checker, it allowed you to see if a device was SmartSync, free run, etc. TheFirePanel.com has gone down, although this forum has not. I built a new site that has the same function, but there are hundreds of different Simplex devices, way more than I can do in my limited free time with school. I decided to allow everyone to add to the database to hopefully create a more complete version quicker.
To add devices to the database: https://wiki.firealarms.gq/index.php/Simplex_Check_Editor
To check devices: https://firealarms.gq/simplex/checker.php
Or to choose where you want to go: https://firealarms.gq/simplex/
This tool is hosted on my site, the editor is available on the https://wiki.firealarms.gq wiki, as I feel it fits better there.
If you discover an issue in the database post here, PM me or email me, the email is on the checker page.
