D-TECT Walktester
GJD380 Installation Tool
Installation & User Guide
The D-TECT WalkTester (Fig.3) is an installation tool that will help the
installer set up GJD D-TECT’s on site.
*Each D-TECT external detector has been tted with and infra-red LED
emitter. When activation occurs the transmitter sends a signal. This
signal is then received by the WalkTester and a very bright white LED
on the WalkTester ashes, also a Piezo speaker sounds.
Under normal situations both the LED and the sounder can be seen
and heard up to 50 meters.
*Please note that some of the earlier versions of D-TECT’s were not
tted with IR transmitters and so the WalkTester will not work with
these units. To verify please take the cover off the D-TECT and look
at the **bottom of the circuit board for a blue IR LED (Fig.1). If this
is present then the WalkTester will be able to communicate with the
D-TECT.

NOTE: For D-TECT 2 and
D-TECT 50 the IR LED is on
the front of the circuit board.
On the D-TECT 3 it is on the
rear PDB.

Powering The Walktester
The D-TECT WalkTester comes with a mounting bracket / holder
(Fig.2).
First t a PP3 battery into the WalkTester battery compartment (Fig.5
& Fig.7). This is done by removing the battery compartment cover as
shown in Fig.4. Please ensure that the on/off switch on the WalkTester
is set to the ‘off’ position while connecting the battery (Fig.6). When
tted close the battery compartment and the WalkTester is ready for
use (Fig.8).

Using The Walktester
Remove the cover from the D-TECT housing by loosening
the stainless steel screw at the bottom of the D-TECT
(Fig.9). This will allow access to the programming button
shown in Fig.10 (and to also verify the presence of the Blue
IR Emitting LED).
The WalkTester will illuminate and sound every time the
D-TECT is activated.
For more information on the walk test procedure please refer
to the relevant D-TECT manual.
When nished testing, turn off the WalkTester and remove it
and the holder from the D-TECT.
Tighten the screw on the base of the D-TECT. The GJD
D-TECT external detector is now ready.

Fig.10. D-TECT programming button
Place the D-TECT into ‘walk test’ mode by pressing the
programme button once (Fig.10). The D-TECT’s clear LED
will then ash out its current settings. Wait for the ashing
sequence to nish. The D-TECT is now in walk test mode
and will remain in that state for ve minutes after the last
detection, where after it will revert to normal mode. Walk
test can be cancelled at anytime by pressing the D-TECT
programme button twice.
REPLACE THE D-TECT COVER and place the WalkTester
in the metal holder.
Slightly loosen the stainless steel screw on the bottom of the
D-TECT, just enough so that the drilled tab on the WalkTest-
er bracket can slide around the screw thread. Then gently
tighten the screw to hold the WalkTester and holder in place
(Fig.11). Note the WalkTester can be orientated around the
base of the D-TECT detector within 180 degree
so as to allow for visibility during walk testing. Turn the
WalkTester on.
