LOCATING THE DETECTOR & SELECTING A LE NS

First, choose the type of coverage which will be best for the
particular area you need to protect.

Standard Wide-Angle Lens

Corner mounting with this lens is preferred as it provides the
best overall coverage. Choose a corner where the path of an
intruder will most likely cross beams, as opposed to walking
towards or away from them. This lens is intentionally made with
an 85 degree angle of view, to help prevent curtains on windows
from being in detection zones.
Sources of heat, such as radiators and space heaters, do not
usually pose a problem as long as hot air from them does not

blow directly

head radiant heaters, these produce very high levels of infrared
energy and can heat the unit at some distance. Mount the unit
as far from these as possible. Do not mount the unit where the
sun can shine directly on it. Mount it away from the direction of
sunlight.

locate the

detector as
high as possible (7 ft. minimum) and avoid placement that
would allow the pets to get within 6 ft. of the detector. It may be
necessary to mask a zone with the supplied material if a stair­case is close to the detector and directly in a zone. It is also
possible to adjust beams laterally by sliding the lens and re­tainer horizontally within its stops.

Pet-Alley Lens (LENS817)

For larger pets use a Pet-Alley Lens (LENS817). This lens pro­vides the same pattern and coverage as the standard Wide­Angle lens, but there are no lower zones. This creates an un­protected “Pet Alley” in which a larger pet can freely move

about. The

removing the screw in the center of the board.

Note:

the screw
is attached to the circuit board and will not separate when
removed. Third, determine the wire entry points on the housing.
The housing provides four possible wire entry points, two for
surface wiring and two for hidden wiring. Determine which entry
is most convenient and punch out or remove the thin plastic
section. Fourth, mount the housing to the wall. There are three
mounting options to choose from depending on the desired
location: flat wall mounting, corner mounting or using the swivel
bracket (SVL2) for ceiling and wall mounting where it is advanta­geous to tilt or aim the unit along a wall.

Note:

using two units on
swivel brackets mounted side by side it is possible to cover
almost 180 degrees when mounted on a flat wall. If using the
swivel bracket refer to the instructions with the bracket. For wall
or corner mounting simply hold the case in the desired location
and using the supplied screws push through the appropriate thin
wall mounting screw holes and attach the unit with two or four
screws.

Note:

Do not over tighten the screws as this can distort
the case and compromise the air seal of the unit, because not all
walls are flat and all corners are square. Reinstall the circuit
board and proceed to wire the detector.

WIRING & TERMINAL DESCRIPTIONS

Refer to the wiring diagram and terminal descriptions, connect
the appropriate wire to the corresponding terminal. When you
have finished wiring the terminals seal the opening around the
wire entry hole and any other unused holes with the supplied
sealer.

Long Range Lens (LENS840)

For longer range coverage the Long Range Lens (LENS840) will
provide up to 100 ft. of range with a single pair of
beams.Complete coverage pattern is included with the lens.

MOUNTING

First, use a screw driver to carefully lift the lens cover from the
housing. Second, remove the circuit board from the housing by
