Hi @Mavrrick58 , seems you are the master over here. I switched the main entry/exit door sensor to “perimeter” type in order to trigger the alarm with no delay, but the system is still delaying the alarm internal siren, starting counting down as the original delay when I programmed first time the sensor as entry/exit. I would like no delay in order to avoid to intruder “look for” the hub and destroy it, I think immediate siren could warning and take the intruder by surprise, any idea why the system is keeping delay? (I set it in Tool Box 30 seconds as delay, is the minimum value permited in the hub screen)
