It is possible to mount the units back to back however when
detectors are mounted in close proximity to one another it
is advisable to carry out a walk test to ensure that external
objects are not influencing the microwave circuit.
During installation, protect the electronics against water, as
trapped moisture can affect or damage the unit.
1.
Drill the wall to accept the two fixing screws, the
cable entry, and the tamper cup (if used). See
Figures 1 and 2. A hole-drilling template is provided.
Note: We recommend using the tamper cup on uneven
wall surfaces.
2.
Remove the cover assembly by loosening the locking
screw. The cover hinges from the top and lifts out of
the location slot. See Figure 3.
3.
Feed standard eight-core alarm cable into the cable
entry. Bare the wires and connect to the top PCB
terminal block. See Figures 2, 4, & 5.
4.
Screw the unit to the wall ensuring that the rear
tamper pin is correctly located and that the tamper
microswitch is closed. See Figure 6. To aid
installation, two spare tamper feet are provided. One
is 1mm longer and the other is 2mm longer than the
tamper foot originally fitted. The tamper foot is a push
fit and can be removed by carefully pulling it from the
pin. See Figure 2.
5.
When the detector is aligned, connected, and
programmed to suit the installation, replace the front
cover and lock as shown. See Figure 7.
CONNECTING THE UNIT
The D-TECT 3 includes jumpers that allow you to configure
the internal end-of-line resistor values, when EOL resistors
are required. Values are 1K, 2K2, 3K3, 4K7, 5K6 and 6K8
Ω.
Figure 8 shows:

Alternatively, you can remove the jumpers and connect a
discrete resistor directly to the alarm or tamper outputs, as
specified by the third-party equipment.

INTRODUCTION
The D-TECT 3 is an outdoor motion detector and alarm
trigger that uses two independent passive infra-red
detectors plus a microwave sensor module. All three
sensors must trigger to cause the detector to signal an
alarm. Utilising triple detection technology, the D-TECT 3
delivers precise, reliable presence detection.
QUICK INSTALLATION
1.
Mount and connect the detector following the
instructions given later in this sheet.
2.
Apply supply voltage to the unit. The detection LED
(blue) flashes three times.
3.
Wait approximately 2 to 3 minutes to allow the
detector to settle.
4.
Press the programming button once to activate walk
test mode. The detection LED is now enabled for five
minutes.
Note: The front cover must be fitted when walk testing.
The default settings are:
•
Range: 20 meters
•
Pulse count: 1 (always set to 1 during walk test)
•
Detection LED: off (always enabled during Walk Test)
•
‘S’ Lux Level: 5
•
Contacts:
Alarm 1: Normally Closed
Alarm 2: Normally Open
•
Contacts Timer: 5 (seconds)
MOUNTING THE UNIT
WARNING
•
NYLON WASHERS PROVIDED MUST BE USED
WITH SCREWS
•
ENSURE CABLE ENTRY AND SCREW HOLES
ARE SEALED WITH WATER BASED SEALANT
•
DO NOT USE SILICONE BASED SEALANT
To reduce the possibility of the microwave circuit being
affected it is recommended to leave a minimum space of 3
metres between D-TECT 3 sensors when mounted along-
side each other. When facing each other a minimum space
of 15 metres is recommended.
