6500 AND 6500S BEAM DETECTOR
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.

REMOTE TEST SWITCH
In the conventional version of the beam detector, an
optical filter is activated from ground level by a hard-wired
connection; in the addressable model it is initiated by a
command from the fire control panel to the servo motor.
The filter attenuates the beam, causing the unit to go into
alarm. This test process provides a complete check of every
component in the alarm path without the need for access at
high level.
