The 6500RS and 6500R are conventional reflector- type linear optical beam smoke detectors designed to operate as components of conventional fire alarm systems. They operate primarily on the principle of light obscuration utilising an Infra-Red beam. Optical beam smoke detectors are particularly appropriate for protecting buildings with large open spaces such as warehouses, atriums etc. The 6500RS and 6500R detectors are combined transmitter/receiver units that can be directly connected to a conventional detector circuit. The Infra-Red transmitter generates a beam of light towards a high efficiency reflector. The reflector returns the beam to the receiver where an nalysis of the received signal is made. The change in the strength of the received signal is used to determine the alarm condition. The 6500RS features Asuretest, the unique remote test capability that fully tests both the optics and the electronics of the device. An optical filter is automatically introduced in front of the optics, attenuating the returned beam and causing the unit to go into alarm. Alignment of the detector is simplified with the aid of the detector’s "gunsight" targeting device. Alignment of the detector with the reflector can then be “fine tuned” with the aid of a numerical signal strength indicator.
