10.1 Description
The BEAM355, BEAM355S, and OSI-RI-FL are intelligent, addressable projected beam smoke detectors, designed for protecting
open areas with high and sloping ceilings and wide-open areas, where spot type smoke detectors are difficult to install and maintain. The
BEAM355S has an integral sensitivity test feature that consists of a test filter attached to a servomotor inside the detector optics.
NOTE: This section provides basic wiring and addressing information For critical information on device installation, operation and
alignment, refer to the Installation Instructions provided with these devices.
10.2 Installation and Wiring
10.2.1 Setting an SLC Address for a Beam Detector
Each beam detector is factory preset with an address of "00." To set an SLC address, use a common screwdriver to adjust the address
rotary code switches on the detector to the desired address (refer to 5.2.1"Setting an SLC address for a Single Point Module" on
page 33).
10.2.2 Wiring a Beam Detector
