D-TectX Signal Strength / Walk Tester

Engineer Instructions

The D-TectX Signal Strength / Walk Tester is a hand held battery powered
device to assist with the installation and alignment of D-TectX wireless
detectors.

The D-TectX Signal Strength / Walk Tester needs to learn the code from the
D-TectX detector being set up. The unit will then indicate when the detector
has activated and also show the strength of the R.F. signal being received.

1. Battery Installation

Remove battery compartment cover, install a PP3 9 Volt alkaline battery and
replace battery compartment cover.

2. Clear Code

Turn the unit on and clear any existing detector codes by pressing and
holding the LEARN button for 4 seconds until the TAMPER red LED starts to
flash, then release the button. The unit is now ready to learn a new detector
code.

3. Learn Detector Code

Plug the detector’s code transfer lead in to the LEARN socket in the end of the
D-TectX Signal Strength / Walk Tester, press and release the detector’s
Programme Button, press and release the LEARN button. After 2 seconds the
Tamper, Signal Strength 2 and 4 LEDs will flash 3 times to confirm the code
has been transferred.
If this does not show then repeat steps 2 – 3.

4. Signal Strength Testing

The detector needs to be put in to transmit test mode by pressing the
Programme Button on the detector 8 times and on the eighth press keep the
button held until the LED goes off then releas the button. The detector will
now transmit a signal every 2 seconds for approximately 8 minutes. This can

be stopped at any time by pressing the detector’s Programme Button for 4
seconds.

When the D-TectX Signal Strength / Walk Tester receives a signal from the
detector, the R.F. signal strength is displayed on the 4 green LEDs.
For optimum results the D-TectX Signal Strength / Walk Tester should be held
in an upright position.

4 Beeps and 4 green LEDs indicates maximum signal strength.
3 Beeps and 3 green LEDs indicates very good signal strength.
2 Beeps and 2 green LEDs indicates good signal strength.
1 Beep and 1 green LED indicates moderate signal strength.
A weaker R.F. strength is indicated by an increased time between signals
being received.
To preserve battery life on the detector it is recommended to exit the
transmit test mode after testing has been completed.

5. Walk Testing

Ensure the detector is not in transmit test mode.
Set the detector to the required detection range and align the detector head
to cover the required area then replace the detector’s cover.
When the detector has detected movement, the D-TectX Signal Strength /
Walk Tester will beep and the blue DETECTION LED will light. The LED
display will remain lit for 15 seconds, pressing the LEARN button momentarily
will clear the display.
After movement has been detected, no further detection signals will be
transmitted for 8 seconds.

To test any further detectors repeat steps 2 – 5.

After 1 minute of the D-TectX Signal Strength / Walk Tester being turned on
but with no detection or button presses then 3 consecutive beeps and blue
DETECTION LED flashes will be indicated.
