CORAL PLUS

Temperature-Compensated PIR Detector

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 low­temperature 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.

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.

2 DE1011

E. Mount the base (equipped with the printed circuit board) in the

location and height selected for optimum coverage. For surface
mounting use the two knockouts at the back of the base; for
corner mounting use the knockouts on the angled sides. The unit
must be fastened firmly to the mounting surface.

3.2 Changing Lenses

To change a lens, remove the screw at the bottom of the unit and
open the front cover. Insert a small screwdriver blade into the slot
between the lens holder and the cover. Lever the handle outward to
release the lens holder (Fig. 2).

Insert the new lens with the smooth surface outside and the lens
designation letter in the upper right corner (Fig. 3). Carefully center
the lens so that the distance from its edges to the edge of the cover is
the same on each side of the cover. Holding the lens firmly in place,
align the lens holder as shown in Figure 3 and push it toward the
cover until a click is heard.

Figure 2. Lens Holder Removal Figure 3. Lens Assembly

3.3 Optional Swivel Brackets

The BR-1 is a swivel,
surface-mounted bracket for
greater flexibility when
setting the detection range.
It is adjusable 30° down­ward and 45° left, 45° right
(Figure 4). The BR-2 is a
swivel bracket kit for room
corners. It consists of the
BR-1 and a corner adapter.

The BR-3 is a swivel
bracket kit for ceilings. It
consists of the BR-1 and a
ceiling adapter.

ATTENTION: With swivel
brackets in use, the
effective detection range
may differ from that
indicated in Table 1 - the
vertical adjusting scale.

Figure 4. Optional Swivel Brackets

3.4 Wiring

To route the wires into the
detector, use either the wiring
knockouts (see Figure 5) or the
wiring channel and its knockout
on the back. The channel allows
routing wires from the ceiling
under the base and then inside.

Connect wires to the terminal
block in the following order.
Refer to Figure 6.

A. Connect the TAMP. N.C.

terminals to a normally closed
24-hour protection zone of the
control panel. The tamper
contact will open when the
cover is removed.

Figure 5. Inside View

B. Connect the N.C. relay terminals to a normally closed burglar

protection zone of the control panel. Relay contacts will open
when motion is detected or during power loss.

For installations in Canada, the N.C. relay must be connected

to an end-of-line resistor supervised zone.

C. Connect the 12V (+) and (–) terminals

to a 9 - 16 Volt DC power source
(observe polarity). The power supply
must have at least 4 hours of battery
backup. The unit’s current drain is
approximately 17 mA.

Figure 6. Terminal Block

3.5 Vertical Adjustment

The vertical adjustment scale (printed on the upper right corner of the
p.c. board) and the plastic pointer on the base indicate in degrees the
vertical angle between the horizontal line of the unit and the upper
detection layer. Table 1 gives the recommended scale setting for
various combinations of mounting height and coverage distance.This
allows fast, easy pattern adjustment from +2° to -12° downward
according to the installation height and the required coverage range.

Table 1 - Vertical Adjusting Scale

Example: if you

require a range of
12 m (40 ft) and
wish to install the
sensor 1.8 m (6 ft)
above the ground,
set the vertical
adjustment Scale
to -5°.

All CORAL PLUS sensors are factory preset to -4°. To change the
vertical pattern adjustment, loosen the screw which fastens the printed
circuit board to the base. Slide the p.c. board up or down to the desired
angle and tighten the screw firmly. A keyhole shaped slot permits easy
removal of the PCB for maintenance by just loosening its securing screw.

Note: In pet alley installations (lens D), set the scale to +2°, and
Install the unit at a height that enables directing the detection pattern
about 30 cm (1 foot) above the pet's activity.

3.6 The Pulse Counter

A programmable pulse counter can be set to count 1 or 3 pulses,
before activating the alarm relay. To set the pulse counter, place the
jumper at the desired setting (1 or 3).

3 Pulses: This setting provides improved protection against false
alarms caused by all types of environmental disturbances. Three
pulses may be selected for wide angle multi-beam lenses, but do not

use it with the long-range lens (Lens B).
1 Pulse: This setting actually disables the pulse counter. It should be

used when necessary to activate an alarm on the first detected pulse,
such as with the long range lens, or in high security installations ­where fast "catch" performance is of greatest importance.

3.7 Walk Testing

A. Apply power and allow 5 minutes for warming up and stabilizing.
B. Adjust the vertical pattern angle per Table 1.
C. Set the pulse counter per Para. 3.6.
D. Walk slowly across the field of view (in opposite directions) and

observe the LED - it lights whenever you enter or exit a sensitive
beam. Allow 5 seconds between each test for the unit to stabilize.

E. After testing, the LED can be disabled to prevent unauthorized

tracing the coverage pattern. To disable the LED, remove the
jumper from the upper and middle pins of the LED selector (ON)
and place it across the middle and lower pins (OFF).

Note: The range and coverage area should be checked at least
once a year by the installer. To assure proper continuous
functioning, the user should be instructed to perform a walk test at
the far end of the coverage pattern to assure an alarm signal prior

to each time the alarm system is armed.
