I recently took over a home with a DSC system installed with the following: Neo HS2032, 2 DSC keypads, TL880, and sensors (door, windows, and motion). The previous owners ran this setup with a local vendor who was also providing monitoring. My issue now is that I do not have the Installer Code. The vendor will not tell me it and the default code (5555) isn’t working either. Do I need this code to setup Surety monitoring?
