The Sequel Security system that was designed for Prodigy (P-Security). That company went out of business. I got a rude awakening when I spec's a system out and went it was time for the install I called Sequel and they were out of business. Very embarrassing to tell this to my client. Still pisses me off typing this because I haven't yet resolved the security system for this Prodigy system. I can't get a good answer from Crestron on what kind of security system to add to this Crestron system. I hate to even attempt to go and try and sell them a PMC3-XP. Anyone here "Affectively" use a security system with a Prodigy system and the PMC2 being the processor.
