•

When mounting the units side by side, a minimum
space of 1 m must be left between the detectors, and
the detectors must not be looking directly towards
each other. No minimum space is required when
mounting the units back to back.

•

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
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 or 12-core alarm cable though the wall and directly
into the cable entry. Bare the wires and connect to the top
PCB terminal block (see Figure 15).

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. Refer to
Figure 1 for good and bad cable routings.

4. Screw the unit to the wall ensuring that the tamper pin is

correctly located and that the tamper micro-switch is
closed. Always ensure the detector base is screwed tightly
to the wall so that the tamper foot is pushed into the rear
rubber gasket. On uneven surfaces use the tamper cup
and locate the tamper foot into the cup. Drilling template is
provided.

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.

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 5.

d. Tighten the locking screw.

Connecting the unit

The DI601AM includes jumpers that let you configure internal
Triple End-of-Line (TEOL) resistor values, when TEOL
resistors are required. Values are: 1, 2.2, 3.3, 4.7, 5.6, and

6.8

kΩ for Alarm and Tamper (DEOL resistors). The values are

2.2, 3.3, 4.7, 5.6 and 10

kΩ for Fault/Anti-Mask.

When using TEOL connections insert the TEOL jumper and
select the three required resistor values for Fault/A Mask,
Alarm and Tamper.

When using DEOL connections remove the TEOL jumper and
select the two required resistor values for Alarm and Tamper.

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

The wiring schematic in Figure 15 shows how to connect the
detector. The examples below show how to calculate DEOL
and TEOL values.
