Yes! Our Fog Cannons are prepared for hidden installation above the ceiling or behind the wall. It just requires a small hole to allow the fog to be fired into the room. However, if the Fog Cannon is placed in a loft ceiling make sure that it is dry and always above 5 degrees C.
If the Fog Cannon does not reach all the way through the wall, we have an extension piece for the nozzle. Just ask your alarm installer.
(Please note that the extension piece CANNOT be used for installations in the ceiling).
