Installation Instructions
1. INTRODUCTION
The CORAL PLUS passive infrared detector is a new, advanced
version of the popular CORAL featuring an increased detection range,
improved stability and enhanced RFI protection (greater than 30 V/m).
The special advantage of the CORAL PLUS is its high-temperature
compensation for maximum "catch" performance, and its unique low-
temperature compensation for optimum false-alarm rejection.
The pyroelectric sensor of the CORAL PLUS is
enclosed in a sealed chamber, protected from insects
and air drafts. The pulse counter may be switched
between 1 and 3 pulses, as desired.
CORAL PLUS has a selection of four interchangeable
lenses - the appropriate lens for each application can
be selected to match the desired coverage.

PATENTS
U.S. Patent No. Des. 346,567
Lens A. Wide Angle (standard)
34 beams in 3 detection layers
Max. Range 15 x 15 m (50 x 50 ft)
Lens C. Ultra Wide Angle
34 beams in 3 detection layers
Max. Range 13.5 x 18 m (45 x 60 ft)
Lens D. Pet Alley
14 beams in a single layer
Max. Range 15 x 15 m (50 x 50 ft)
Lens 306. Cylindrical
7 curtain type beams
Max. Range 9 x 9 m (30 x 30 ft)
Lens B. Long Range
Narrow angle corridor pattern
Max. Range 3 x 27 m (10 x 90 ft)
Note: To allow extra free height for
pets, set the vertical adjustment scale
to +2°. Install the detector at a height
that places the detection pattern at
least 1 ft (30 cm) above the pet’s
activity.
Note: This lens is used for improved
detection in close proximity to the
detector. Motion occurring at least
1 m (3 ft) away from the detector will
be reliably detected .

3. INSTALLATION
3.1 Mounting
The CORAL PLUS can be installed directly on a wall (surface
mounted) or in a corner. For optional swivel brackets, see Para. 3.3
and Figure 4. Always mount the unit on a firm and stable surface.
A. Select the mounting location so that the expected motion of an
intruder would cross the beams of the coverage pattern.
B. Select the most convenient mounting height. Built-in installation
aids enable you to mount the unit anywhere up to a 3.6 m (12 ft)
height. An accurate adjustment table (Table 1) determines the
recommended angles for various combinations of range and
mounting height.
C. CORAL PLUS is extremely immune to air turbulence and RF
interference (RFI). However, to minimize possible false alarms, it
is highly recommended to avoid aiming the detector at heaters,
sources of light or windows subjected to direct sunlight. Also avoid
running wiring close to high power electrical cables.
D. To open the front cover, remove the screw at the bottom of the
unit. Separate and remove the front cover from the base.
