I just installed an Elk M1 panel, and I am having trouble arming directly to "Stay" mode via the keypads (M1KPNAV & M1KP). I hope I have overlooked something very simple. Here goes. I only have one area (#1). I have "single keypress quick-arm enabled" and "auto stay mode after exit time if no violation" enabled. When I press "Stay" on either keypad, I get an error sound and no action. When I press "Away" and there is no exit violation, the exit timer will count down, and the system will automatically and correctly arm to "Stay". Also, I am able to arm directly to "Stay" via Elk RP. I have numerous perimeter zones and one interior PIR zone. The system shows "Ready to Arm" prior to pressing "Away" or "Stay". Any assistance would be appreciated...Thank you.
