QUICK START GUIDE
OSI-RE-SS
Smoke Detection System
This guide provides information on how to install the OSI-RE-SS Smoke Detec-
tion System.
Extensive product and critical product security information can be found
in the OSI-RE-SS Installation Guide (Document No. E56-6654) available at
www.systemsensoreurope.com/products/category/beam-smoke-detectors/
.
The OSI-RE-SS system consists of an Imager and a reflector.
The products shall be powered from a EN54-4 certified AC/DC Power convert-
ers to be in compliance for CE certification.

DETERMINE THE POSITIONS OF THE IMAGER AND REFLECTOR
COMPONENTS
Make sure that the intended mounting locations meet the following criteria
(See Figure 2.):
• Detector spacing must comply with local codes and standards
• Reflector must be located within the Field of View (FOV) of the Imager
• Clear path between the reflector and Imager
• Mounted well above the head-height of people and obstructions
• Avoid direct sunlight onto the units
The Imager and reflector should be placed within a recommended distance
below the ceiling. (See Figure 3.) This value will vary according to regional
specifications, geometry, and specific requirements for the installation. The
distance for flat ceilings and basic spacing requirements (S) is shown in the
following table.
