GENERAL

The model 6500R is a conventional long range projected beam smoke
detector designed to provide open area protection. It consists of a
combined transmitter/receiver unit and a reflector. Smoke entering the
area between the two components causes a reduction in the signal
returned to the receiver. When the obscuration reaches alarm
thresholds, selected at the transmitter/receiver unit, the detector
generates an alarm signal. Complete blockage of the beam causes a
fault signal. Slow changes in obscuration due to a build up of dirt or
dust on the lens of the detector are compensated for by a micro­controller that continuously monitors the signal strength and
periodically updates the alarm and fault thresholds. When the self­compensation circuit reaches its limit, the detector generates a fault
signal, indicating the need for service. After local testing is complete,
the yellow LED will blink a pattern to indicate the level of drift
compensation employed during the test (see Blinks Output by Yellow
LED table at back of manual).

The model 6500RS includes an integral servo controlled calibrated test
filter, which allows automatic remote alarm testing.

APPROVED ACCESSORIES
6500-LRK/BEAMLRK

Long Range Kit comprising three additional 20cm x 20cm reflectors,
which may be mounted in a square with the supplied reflector,
permitting the detector to be used for ranges from 70m to 100m.

6500-MMK/BEAMMMK

Multi-Mounting Kit allowing the 6500 to be mounted to ceilings, or to
walls where the detector and reflector cannot be mounted within 10° of
one another. One kit mounts either the transmitter/receiver unit or
reflector. If the transmitter/receiver is mounted on the 6500-MMK/
BEAMMMK, then the 6500-SMK/BEAMSMK must be used. Note that
only a single 20cm x 20cm reflector can be mounted using the MMKs:
The 6500-LRK/BEAMLRK is not compatible with the MMKs.

6500-SMK/BEAMSMK

Surface Mounting Kit for the transmitter receiver (also used in
combination with the MMK) to give an additional 43mm depth to assist
surface mounting and to permit side entry cabling.

6500RTS-KEY

Remote test and annunciator accessory that enables the detector to
be tested remotely, providing test and reset functions, a Red LED to
indicate alarm conditions and a Yellow LED to indicate fault conditions.

DETECTOR MOUNTING
Location

The 6500 must be located in accordance with local standards and
guidelines, for example BS5839 part 1. For general information, refer
to the application guide for projected beam smoke detectors available
on request from your supplier.

Mounting Position

Beam detectors require a very stable mounting surface for proper
operation. A surface that moves, shifts, vibrates, or warps over time
may cause false alarm or fault conditions. Initial selection of a proper
mounting surface will eliminate nuisance alarms and fault signals.
Mount the detector on a stable mounting surface such as brick,
concrete, a sturdy load-bearing wall, support column, structural beam,
or other surface that is not expected to experience vibration or
movement over time. DO NOT MOUNT the beam detector on
corrugated metal walls, sheet metal walls, external building sheathing,
external siding, suspended ceilings, steel web trusses, rafters, non­structural beam, joists, or other such surfaces. The reflector has a
much greater tolerance to movement than the transmitter/receiver,
hence in cases where only one stable mounting surface as defined
above can be used, the transmitter/receiver unit should be mounted to
the stable surface. See specifications for maximum permissible
angular misalignment; movement outside these limits may cause
nuisance alarms and faults.

Mounting Considerations

• There must be a permanent clear line of vision between the
detector and the reflector.

• Reflective objects should be a minimum of 380mm from the line of
sight between the detector and reflector to avoid compromise of
the protected area by reflected light.

• Direct sunlight or strong lights into the transmitter/receiver unit
should be avoided. There should be a minimum of 10° between the
paths of the light source and the detector beam.

• Operation of the detector through panes of glass should be
avoided if possible. If it is necessary to pass though glass, the
angle between the beam and glass should be set a minimum of 10°
off perpendicular, and operation through multiple panes should be
avoided.

Mounting

The transmitter/receiver unit may be mounted directly to the wall, with
rear cable entry. The detector base has four primary mounting holes,
one in each corner of the base. All four holes must be used to provide
secure mounting. In order to mount the detector to the wall, the outer
cover must be removed after unscrewing its four retaining screws.

Please refer to the relevant kit instructions if the transmitter/receiver is
to be mounted onto the 6500-SMK/BEAMSMK or 6500-MMK/
BEAMMMK allowing more flexibility for cable entry.

Figure 1: Transmitter/Receiver Wall Mounting

The reflector is mounted directly to the wall using all four of its
mounting holes, one in each corner. The reflector must be mounted
such that the plane of the reflector is perpendicular to the optical line of
sight to the transmitter/receiver unit. The maximum tolerance for non­perpendicular mounting locations is 10°. If this tolerance is not
possible, then the MMK should be used, see MMK instructions for
mounting details.

WIRING

Note: All wiring must be installed in accordance with local
requirements.

Warning: Before working on the system, notify the proper authorities
that the system is undergoing maintenance and will be temporarily out
of service.

Wiring connections are made to pluggable terminal blocks, which can
accept wire sizes from 1mm² to 2.5mm². For best results screened
cable should be used. Refer to the control panel instructions for cable
type limitations
