Siren help needed

Cannot get the Fortrezz siren to work via the app. I had it connected initially, then took it out of network. Now I can’t get the network to find it again. I’ve tried to exclude, but network can’t find it to exclude it. Help please

It does not need to see it. Do a general exclude on the hud in IDE and then follow the device exclude procedure.

Thanks. I have it reinstalled but still cannot control the siren through IDE. Do you have any suggestions? The alarm works when pressing the tester on the back of the alarm but will not through the app

If i am not mistaken it is set like a dimmer sw. 0-33 strobe 33-66 siren 67-100 both.
