Orion External Sounder
The Orion external sounder is low profile and comes in two versions, Vertical and Horizontal. The backplate is made from 3mm polycarbonate and has adjustable wall mountings to allow for the movement of the fixing holes when installing. Molded into the backplate are two knockout spacers (2mm & 4mm) for use on uneven surfaces.
The cover is also made from 3mm polycarbonate and comes complete with either one or two lenses depending on the version. The special hinged flush fitting covers conceal the cover screws.
