INSTALL
Caution:
To avoid damage to your unit or incorrect fitting,
take account of the following cautions:
1.
The mini Opal is design for mounting vertically on
a flat surface. Do not mount it on the underside of
a roof edge because the sensor cannot be angled
correctly in this orientation.
2.
The range and focus of the mini Opal can be affected
by grease on the lens or sensor, Always hold the lens
by the edges and do not touch the sensor. If touched,
clean with an appropriate soft, lint-free cloth.
3.
Do not install your mini Opal outside during wet
conditions such as rain or mist. Moisture inside the
case can cause faults. The moisture will remain in the
air-tight enclosure indefinitely.
MOUNT
1.
Choose a mounting position, it should:
-
Be 60cm (2ft) from lamps
-
If possible, allow the wiring to be run through
the wall
-
Be smooth enough to hold the tamper plate
in position and provide a good seal against the
expanded foam back plate
-
Make allowance for obstacles that may cause
a varying thermal image. For example, trees
or shrubs in a wind, ripples on ponds (or large
puddles), boiler flues and animals
2.
Remove the cover
3.
To reveal the two cable access, unscrew the top,
plastic wing-nut and, remove the circuit board and
lens unit.
4.
The cable entry holes are protected by two sealed
grommets. Use a screwdriver to punch out the centre
of the grommets you intend using.
5.
Hold the unit to the mounting surface and mark the
location of mounting and cabling holes.
WARNING
: To prevent damage to the unit, do not drill
through the holes in the back of the case.
Always make the appropriate checks to ensure that the
surface you are drilling does not contain mains electrical
wiring or plumbing. Failure to do so can result in injury or
death by electric shock.
6.
Feed the cable(s) through the grommet(s) and fix the
unit in your chosen location using appropriate fixings.
CONNECT:
To prevent damage to your mini Opal or
lighting controller, switch off the power before making
connections
1.
Connect the +, A, S and wires to the screw-terminal
block on the back of the sensor PCB.
Figure 6: Rear of PCB with Connections
2.
Optionally connect the tamper output on the top PCB to your
alarm system.
NOTE:
The twin tamper switches provide a single volts-free,
normally-closed alarm output once the mini Opal is mounted to the
wall and the cover is fitted.

Connect External Buzzer or Relay
(on Page
2/3)
When the power is applied, the red LED flashes for 0.6 seconds
before stopping. The LED is normally off during operation.
CONNECT EXTERNAL BUZZER OR RELAY
The unit can drive and external relay output or a piezo buzzer. The
component specifications for the diagrams are:
•
Diodes: 1N4148 / 1N4002 or similar - observe the band when
connecting
•
External relay: 12V DC, 470ohm minimum coil resistance
•
Piezo buzzer: 12 V DC, 3mA, 80dB (A) at one metre
Energizing a relay from the A or S connections
When the external relay is connected to the A connection, it will
trigger for every detection and deactivate immediately. By connecting
the relay to the S connection, the external relay stays active from 60s
following the last detection.
