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: 30 meters / 98 feet
•
Pulse count: 1
•
Detection LED: off
Mounting the unit
During installation, protect the electronics against water, as
trapped moisture can affect or damage the unit.
We recommend that the cable entry and screw mounting holes
are sealed from within the detector using acrylic (
non
-silicone
based) sealants.
Note:
When locating the detector, please ensure the detector's
field of view is unobstructed.
To mount the detector:
1. Drill the wall to accept the two fixing screws, the cable
entry, and the tamper cup (if used). See Figures 1 and 3.
A hole-drilling template is provided.
Notes
•
Leave a minimum 10 cm (4 inches) clearance above
the top of the detector housing to allow the cover and
the detector to be positioned correctly.
•
We recommend using the tamper cup on uneven wall
surfaces.
•
The recommended optimum mounting height for the
detector is 3 m. Whilst it is possible to mount the unit
higher, this will give a reduced detection range and
will require the detection subject to move further
through the already reduced detection area before an
activation is signalled.
2. Remove the cover assembly by loosening the locking
screw. Squeeze the sides of the front cover to release the
internal catches. The cover hinges from the top and lifts
out of the location slot. See Figure 2.
3. Use a razor knife to open a rubber seal to allow the
cabling into the unit (see Figure 4). Feed standard eight-
core alarm cable though the wall and directly into the
cable entry. Bare the wires and connect to the top PCB
terminal block (Figure 5, item 2).
Caution:
Do not allow the cable to be trapped between
the rear gasket and the mounting surface as this may
cause water ingress. For surface mount cables use the
conduit knock-out at the bottom of the detector.
4. Screw the unit to the wall ensuring that the tamper pin is
correctly located and that the tamper microswitch is
closed.
To aid installation, two spare tamper feet are provided.
One is 1 mm shorter and the other is 1 mm 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 1.
5. When the detector is aligned, connected, and
programmed to suit the installation:
a. Fit the cover to the detector base.
b. Lightly screw the locking screw.
c.
Put the top of the locking tool into the small notch on
each side of the cover, and then apply slight pressure
until the cover locks into the base, as shown in
Figure 17.
d. Tighten the locking screw.
Connecting the unit
DI601 includes jumpers that let you configure internal end-of-
line (EOL) resistor values, when EOL resistors are required.
Values are: 1, 2.2, 3.3, 4.7, 5.6, and 6.8 kΩ. Figure 5 shows:
1. EOL resistor jumpers
2. Wiring points
Alternatively, you can remove the jumpers and connect a
discrete resistor directly to the alarm or tamper outputs, as
specified by third-party equipment.

Multibeam alignment and masking
The multifunction lens fitted to the DI601 detector produces
seven long-range beams and seven medium- to short-range
curtain PIR beams. The PIR circuitry detects changes in heat
and movement in the beam pattern; therefore items such as
trees, shrubs, ponds, boiler flues, and animals should be
considered when positioning the detector.
Note:
PIR sensor is more sensitive to a movement across the
beams, and less sensitive to a movement directly towards or
away from the beams.
The detector module is fitted with two sliding shutters to reduce
the detection angle.
The curtains are fitted to the pan and tilt module as shown in
Figure 6. Each section of the detector lens gives a coverage
pattern of approximately 10 degrees.
An additional set of curtain sliders is provided should the beam
pattern be narrowed even further, e.g. if the minimum detection
angle of 10 degrees is required.
When coverage exceeds the desired detection area, adjust the
module as required and mask off any beams, either vertically
or horizontally, to avoid unwanted detection.
