Programmable Options; Pulse Count - GE DDI602 Manual De Instrucciones

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.
Use portions of the self-adhesive silver mask applied to the
rear, smooth side of the lens as shown in Figures 9 to 12.
Gently lift the top and bottom edges of the pan and tilt module
to release the lens. To replace the module, please begin by
sliding one side of the lens into the clips on the pan and tilt
module. After one side is secure, do the same for the opposite
side. Once both sides are secure, gently lift the top and bottom
edges of the pan and tilt module and press on the lens to click
it into place.
Always replace the lens the correct way up to ensure exact
beam pattern coverage. The top of the lens is marked TOP as
shown in Figure 7.
Table 2 below summarizes typical masking configurations for
use when the range option is set to 30 meters.
Table 2: Masking configurations for maximum range
Configuration Height
(m / ft.)
Multibeam, optimum 3 / 10
Multibeam 6 / 20
Pet immunity [1] 1.5 / 5
Curtain coverage [2] 6 / 20
[1] Black area should be masked for pet alley applications up to
30 meters / 98 feet.
[2] Black area should be masked for curtain coverage applications.
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. Item 1 is the microwave
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.

1. 90° mounting, not recommended
2. 55° mounting, recommended
3. Detector housing
4. Long range beam direction
5. 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.
The 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.
When the pulse count is set to 1, the detector is most sensitive.
Detection LED enabled
• Off: Detection LED is disabled
• On: Detection LED signals detection

1. Range (m / ft.)
2. Pulse count
3. Detection LED
* Default settings
To change any of 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.
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.
