Base unit not beeping on entry in AWAY mode
I'm having an issue with my Original Simplisafe when I arm the system in AWAY mode and leave the house. When I return, the base unit does not beep or display any message indicating that the PIN is required. We therefore assume that we forgot to set it. Then a minute or two later, the siren goes off. The system has worked flawlessly for years. The batteries have been replaced but the problem persists.
