Sensors and beveled windows and doors

[AAS400]

I'm thinking of installing a Pyronix alarm system and wonder how you get around windows and doors that have beveled sdes? My two front doors, main entrance and hallway don't sit flush on the internal side so would you mount the main sensor on a block of sorts to the side to bring it inline with the door? The back door is flat and flush with the surround so not a problem there. Then theres windows, all with bevels on the surround and not that big to take the main unit which would have to fit on the window itself. You may be able to see what I mean re the doors from the photo.
Thanks for any suggestions. Bri

Pyronix sell spacer blocks , a more zoomed out picture may help

look at operating distances, and then look at spacers.

wish there were more manufacturers offering spacers.
