Figure 13 shows the pattern for the maximum range in the
optimum position (see Figure 9). Masking the top section of the
lens reduces the range to 20 m / 66 ft.
coverage, item 2 is the PIR pattern.
Figure 14 shows the pattern for the minimum range (10 m / 33 ft.)
In this case masking the top section of the lens reduces the range
to 6 meters.
Figure 15 shows possible alignments when the detector is
mounted close to a wall.

Wall
The alignment shown as item 1 in Figure 15 is not recommended.
If the detector head is mounted at an angle of 90° to the
perimeter, the mounting wall may cut off short and medium range
beams. The long-range beam still will detect an intruder, however
the wall can cause false alarms when heated by sunlight.
Item 2 in Figure 15 shows the recommended alignment. The
detector head is mounted at a 55° angle to the perimeter. As a
result, short and medium range beams are parallel to the
perimeter, but the detection range along the perimeter is reduced
to 25 m.

Pulse count
Pulse count is the number of times the detector must detect a
presence before signalling an alarm.
If the PIR/MW logic option is set to AND, detection must occur on
both PIR and microwave sensors to be counted. If the option is set
to OR, a detection on either type of sensor is counted.

Detection alarm
Walk tester communication
DI601 / DDI602 includes magnetically immune, volt-free relay
contacts that can be used to trigger alarm inputs on connected
equipment.
The contacts are rated at a maximum of 24 V AC/DC at 50 mA.
The contacts can be set to operate only when both the microwave
AND the PIR circuits have detected movement (the default setting).
Alternatively the contacts can be programmed to operate when
either the microwave OR the PIR circuit has detected an alarm. In
this case the PIR alarm is signalled on the N/C contact, and the
microwave alarm is signalled on the N/O contact.
Note:
Rain can cause false alarms from the microwave sensor.
When the pulse count is set to 1, the detector is most sensitive.

* Default settings
To change any of DI601 / DDI602 settings:
1.
Press the programming button to select the option number
you want to change.
Press once for range, twice for pulse
count, and three times for detection LED. Press once for
range, twice for pulse count, three times for detection LED,
and four times for PIR/MW logic.
2.
Wait until the programming (red) LED turns off (typically
4 seconds).
3.
Count the number of times the programming LED flashes to
determine the current value for that option.
4.
Press the programming button to select the value number for
the new setting. Example: To set the range to 30 m / 98 ft.,
press three times.
The programming LED blinks twice to indicate that the new
value was set.
Any alterations made to DI601 / DDI602 settings are stored in the
detector's nonvolatile memory.
Example
To change the detection LED setting from OFF to ON:
1.
Press the programming button three times.
2.
Wait until the programming LED turns off.
