A method and apparatus wherein the method includes the steps of generating a globally unique identifier (GUID) for a security system appliance, saving a public key and private key of the security system appliance in a memory of the security system appliance, a manufacturer of the security system appliance generating a signed version of the GUID and the public key, saving the signed version of the GUID and public key in the memory of the security system appliance, the security system appliance sending a registration message including the signed version of the GUID and public key to a security system server and the security system server authenticating the security system appliance using the signed version of the GUID and public key of the security system appliance and a public key of the manufacturer.

System and method of using a signed GUID

A Vplex polling loop device is disclosed which can automatically detect and isolate shorted or overloaded sections of a polling loop, before or after polling loop power and signaling is switched to the output of the device, permitting normal operation of the remaining portion of the polling loop. The Vplex short and overload isolator (VSOI) is usable on former, existing, and future polling loop systems without the need for any software or hardware changes to the associated controls, and may also be used on 2-wire DC voltage distribution systems within the voltage and current limits of the VSOI. It is capable of multiple use anywhere on a polling loop while requiring minimum power from the polling loop. Finally, in the process of detecting and isolating a short or overload on its output, it prevents that short or overload from causing other VSOI devices on the loop to erroneously disconnect their protective branches of the loop.

An Addressable Electronic Switch (AES) is disclosed together with unique S/W (software) procedures for a system control to detect, locate, and isolate shorts, overloads, and other troubles, such as temporary breaks or disconnects, on a Vplex or similar 2-wire polling loop. The addressable electronic switches are placed at strategic locations throughout the polling loop, and are individually commanded by the system control to either connect or disconnect its respective branch from the rest of the polling loop, to locate and isolate a troubled area from the rest of the polling loop.
