LOCATING THE DETECTOR
Select a detector location that will provide the coverage
required keeping in mind the following potential problems
Reflective Surfaces
Do not aim the detector at reflective
surfaces such as mirrors or windows as this may distort the
coverage pattern or reflect sunlight directly onto the detector.
Air Flow
Avoid locations that are subject to direct high air flow
such as near an air duct outlet.
Moisture
Do not locate the detector near sources of steam or
oil.
Sun
Do not aim the detector such that it will receive direct or
reflected (mirror) sunlight,
Pets
If there are pets on the premises, use the pet alley lens.
Obstructions
Do not limit the coverage by large objects
within the detection area such as plants or filing cabinets.
VERTICAL ADJUSTMENT
Using the Mounting Height Chart, set the vertical adjustment to
obtain the desired coverage. Ensure that the PCB retaining
screw is tightened just enough to prevent board movement.
JUMPER J1
will enable/disable the alarm LED. If J1 is OFF,
the LED will not operate on alarm. If J1 is ON the LED will
operate on alarm.
NOTE:
The corridor lens should not be used in corridors that
are less then 5' in width and the installation should be carefully
checked to ensure that the beams are aimed directly down the
centre of the corridor.

CHANGING LENSES
The Bravo4 is supplied with the “wall-to-wall” lens. To
change the lens, release the top tab and pull the lens holder
out. This action releases the lens. Insert the lens with the
GROOVES FACING INWARD. The bottom of the lens is
indicated by two triangular indentations. Ensure that the lens
is centred left to right then reinstall the lens holder. The lens
holder will snap into place sealing the lens into position.
WALK TESTING
Once the detector has been set up, walk test the entire area
where coverage is desired. Should the coverage be incomplete,
re-adjust or relocate the detector to obtain full coverage. Once
coverage is as required, the alarm LED may be disabled by
setting J1 to OFF.
IMPORTANT NOTE:
Upon installation, the unit should be
thoroughly tested to verify proper operation.
The detector should be walk tested weekly by the end user and
yearly by the installer.
DM-C and DM-W
Detector Mounting Brackets
Use the optional DM-W Wall Mount and DM-C Ceiling Mount
brackets to solve difficult placement problems. The DM-W and
DM-C mount to either the wall or ceiling and allow for full vertical
and horizontal positioning of the motion detector - the detector
can be tilted up or down and rotated through 90° to obtain the
best position for optimal coverage. The Bravo PIR has been
designed to be fully compatible with the DM-W and DM-C
brackets. Contact your DSC distributor for more information.
NOTE: This unit is UL Listed
and should be connected to a
listed control unit or power
supply providing at least 4
hours of standby power.
Limited Warranty
Digital Security Controls Ltd. warrants that for a period of 12 months from the date
of purchase, the product shall be free of defects in materials and workmanship under
normal use and that in fulfilment of any breach of such warranty, Digital Security
Controls Ltd. shall, at its option, repair or replace the defective equipment upon
return of the equipment to its repair depot. This warranty applies only to defects in
parts and workmanship and not to damage incurred in shipping or handling, or
damage due to causes beyond the control of Digital Security Controls Ltd. such as
lightning, excessive voltage, mechanical shock, water damage, or damage arising
out of abuse, alteration or improper application of the equipment.
The foregoing warranty shall apply only to the original purchase, and is and shall
be in lieu of any and all other warranties, whether expressed or implied and of all
other obligations or liabilities on the part of Digital Security Controls Ltd. Digital
Security Controls Ltd. neither assumes, nor authorizes any other person purporting
to act on its behalf to modify or to change this warranty, nor to assume for it any other
warranty or liability concerning this product.
In no event shall Digital Security Controls Ltd. be liable for any direct, indirect or
consequential damages, loss of anticipated profits, loss of time or any other losses
incurred by the buyer in connection with the purchase, installation or operation or
failure of this product.
Motion detectors can only detect motion within the designated areas as shown in
their respective installation instructions. They cannot discriminate between in-
truders and intended occupants. Motion detectors do not provide volumetric area
protection. They have multiple beams of detection and motion can only be de-
tected in unobstructed areas covered by these beams. They cannot detect motion
which occurs behind walls, ceilings, floor, closed doors, glass partitions, glass
doors or windows. Any type of tampering whether intentional or unintentional
such as masking, painting, or spraying of any material on the lenses, mirrors,
windows or any other part of the detection system will impair its proper operation.
Passive infrared motion detectors operate by sensing changes in temperature. How-
ever their effectiveness can be reduced when the ambient temperature rises near or
above body temperature or if there are intentional or unintentional sources of heat
in or near the detection area. Some of these heat sources could be heaters, radia-
tors, stoves, barbeques, fireplaces, sunlight, steam vents, lighting and so on.
Warning: Digital Security Controls Ltd. recommends that the entire system be
completely tested on a regular basis. However, despite frequent testing, and due
to, but not limited to, criminal tampering or electrical disruption, it is possible for
this product to fail to perform as expected.
Important Information: Changes or modifications not expressly approved by
Digital Security Controls Ltd. could void the user’s authority to operate this
equipment.
