Linear smoke detectors
The 6500S and 6500 are addressable reflector-type linear optical beam smoke detectors that can be directly connected to an analogue loop circuit as a component of an intelligent fire alarm system. The detectors have a range of 5m to 70m, extending to 100m with a long-range reflector kit.
The 6500S and 6500 detectors are combined transmitter/receiver units. The Infrared 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 6500S features a 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.
Both versions incorporate automatic drift compensation, whereby the detector will adjust its detection thresholds in line with any long-term signal reduction of the beam caused by contamination of the optical surface.
The 6500 and 6500S also include built in short circuit isolators (which may be wired out if required), reducing the number of isolators required in the detection circuit.
