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.

3.0Mounting

3.1Surface 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).

Figure A - Location of the system’s major items.

•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.
