RF CONTINUITY TEST
It is advisable to test the RF signal at the
detector location prior to installation.
To enter the RF continuity test mode - press
the program button on the Opal RFX 'eight'
times. On the eighth press - 'hold' the button
down for 5 seconds until the LED goes out
- the LED indicator will then flash and
transmit one signal per second to the receiver.
The corresponding channel indicator on the
receiver will also flash once per second if
there is a strong RF link established.
This test mode will automatically cancel in
five minutes. Alternatively to cancel the ' RF
continuity test - press and hold the program
button until the LED lights then release.
If it is necessary to conduct a site survey
prior to installation of this equipment it is
advisable to power the RFX-3 Receiver
temporarily with a PP3 (9volt) battery.
Register one detector, then conduct an RF
continuity test as detailed above. As the
signals to the receiver are sent once per
second the optimum position of both the
Opal RFX and the RFX-3 Receiver can be
easily established .
CHANGING THE RANDOM CODE
In the unlikely event of another radio signal
affecting the correct operation of a single
channel. The Opal RFX detector can generate
an alternative random code.
Press the program button on the Opal RFX
nine times. On the ninth press 'hold' the
button down for 5 seconds until the LED
goes out, then release the button
Then erase the code from the RFX-3 Receiver
by holding down that 'channel button' until
the beeps stop, then repeat steps '2' to '6' of
the 'Setup' procedure to register the new
code.
OPAL RFX INSTALLATION
:
During installation the electronics must be
protected against water, as trapped moisture
can effect or damage the unit.
1) First remove the front polythene cover by
pulling forwards, then remove the lens
module by pulling it out of the forked
bracket.
2) Drill the wall to accept the fixing screw
supplied with the wall plug.
3) Fit the housing to a secure surface. When the
surface is uneven use the 4mm spacer
supplied to ensure that the radio signals
transmitted achieve their optimum distance.
4) Always ensure when replacing the module
that it is the correct way up for the
correct alignment of the beam pattern.
(See page 7 Multibeam lens data)
TESTING THE OUTPUTS
(Alignment of the detection beams)
The range of the detector increases with-
out the front protective cover. Therefore
the front cover must be fitted to establish
the correct beam pattern alignment and
when testing the outputs.
When the 'program' button is pressed
momentarily the red indicator lights and
pulse count '1' is automatically selected. The
unit can then be aligned. The red indicator
will light on the Opal RFX and the respective
Channel indicator will flash every time a
detection takes place. This test mode will
automatically cancel five minutes after last
detection. Alternatively, to cancel this 'walk
test mode' press the program button twice.
