I have the Almond+ configured as a router and home automation system. I have two door sensors, a siren and a remote key. All have been successfully activated and linked on the Amond+. But when the system is armed armed, and a door is open, the status shows the door sensor as open but the siren does not go off. If I turn the siren on through the web interface, it does go off. Any idea what I might be missing? Thanks you.
