2.0 Installation Considerations
• Stay within the listed maximum range.
• Install the system with a clear line-of-sight between the transmitter
and receiver. If installed outdoors, make sure trees, weeds, plants,
etc. will not interfere with the beams.
• Use care when installing near reflective surfaces (i.e. glossy walls
or floors). Care should be taken during alignment to ensure beams
are line-of-sight aimed and are not reflecting off surfaces.
• Do not install the units where they may be immersed in water or
subject to corrosive liquids or sprays.
• Do not install the receivers where they will be facing an intense
source of light (e.g. a rising or setting sun). If the sun can not be
avoided, mount the receiver slightly higher than the transmitter. Aim
the receiver down at the transmitter.
• Do not install the receivers where sunlight could be reflected directly
into the receiver optics.
• Do not install either unit on movable surfaces or surfaces subject to
strong vibrations.
3.0 Mounting
3.1 Surface Mounting
NOTE: The recommended mounting height is 3 feet (1 m). However,
mounting height will change depending on the anticipated
intruder catch area.
• Choose the appropriate mounting locations. They should be rigid
and provide a clear line-of-sight between the transmitter and receiver.
• Remove the transmitter’s cover by loosening the cover mounting
screw (see Figure A).

• Place the provided template onto the mounting surface and mark
the holes for its two mounting screws (supplied).
NOTE: Be sure all wiring is unpowered before routing.
• Route wiring (for wire size see Section 4.0) through the transmitter’s
wire entrance, leaving enough to properly wire the transmitter.
• Mount the transmitter to the mounting surface. Firmly tighten the
screws.
• Repeat this complete mounting procedure for the receiver. Be sure
to mount the receiver in direct line-of-sight with the transmitter.
3.2 Pole Mounting
NOTE: The recommended mounting height is 3 feet (1 m). However,
mounting height will change depending on the anticipated
intruder catch area.
NOTE: Use optional MB series poles or equivalent.
• Choose the appropriate mounting location. Install the poles with a
clear line-of-sight between the transmitter and receiver.
• Remove the transmitter’s cover by loosening the Cover Screw (see
Figure A).
• Firmly attach a mounting plate and U-clamp to the pole (see Figure
B) with the screws supplied. Make sure they are line-of-sight aimed
so the transmitter and receiver will be aligned.
