Conventional Beam Detectors – 6500R / 6500RS

The 6500R and 6500RS are conventional reflector-type linear optical beam smoke detectors, designed to operate as a component of an intelligent fire alarm system and typically used for protecting buildings with large open spaces.

The 6500R and 6500RS 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 analysis 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.
