This guide provides information on how to install the OSI-RE-SS Smoke Detection
System.
Extensive product and critical product security information can be found in
the OSI-RE-SS Installation Guide (Document No. E56-6654) available at
https://www.systemsensoreurope.com/products/conventional-beam-detectors-osi-re-
ss/.
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 converters to
be in compliance for CE certification.
FIGURE 1. IMAGER AND REFLECTOR
DETERMINE THE POSITIONS OF THE IMAGER AND REFLECTOR
COMPONENTS
Make sure that the intended mounting locations meet the following criteria (See Fig-
ure 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.
Standard Distance from Ceiling
NFPA 72 300 mm (12 in.) minimum
AS1670.1 25 to 600 mm (1 to 23.6 in.)
BS5839.1 25 to 600 mm (1 to 23.6 in.)
GB50166 300 to 1000 mm (11.8 to 39.4 in.)
For full information on spacing requirements, please refer to your local codes and
standards.
