Section 10: Addressable Beam Detectors
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.
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
Typical wiring of a BEAM355 beam detector connected to an SLC is illustrated in the figure below.
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.
