• Standby:

Intended for connection to DC power
supplies capable of supplying power if
primary power fails.

• Relay:

Alarm activated Form “C” with dry
contacts rated at 0.5 amps max. @
30 VAC and DC.

• Tamper:

Normally Closed with cover in place.

• Pointability:

The optical module can be adjusted
±90° horizontally or  ±24° vertically.

• Temperature:

-13°F to +130°F (-25°C to +55°C).

• Trigger Response Time:50 to 700 milliseconds, selectable.

• 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.

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.

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.
