Mounting Plate Security Screwc

Hello, we have accidently lost the security screw from the mounting plate of the outdoor siren during installation, I want to get a suitable replacement screw and would be grateful if anyone can let me know the thread size I need to get. Thank you, Keith

Hi @Alesampler. The security screw you are referencing has a small spring attached to it. For this reason, you will not likely find it at a hardware store. Try contacting our support team for a replacement. Please give our support team a call at one of the numbers available here.
