Table 2 below summarizes typical masking configurations for 
use when the range option is set to 25 meters.

[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 11 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 18 m / 59 ft. Item 1 is the microwave 
coverage, item 2 is the PIR pattern. 

Figure 12 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 13 shows possible alignments when the detector is 
mounted close to a wall.

The alignment shown as item 1 in Figure 13 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 13 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 20 m. 

LEDs are shown on Figure 16.

Pulse count is the number of times the detector must detect a 
presence before signalling an alarm. 

The DDI602U-F1 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.

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. 

Any alterations made to DDI602U-F1 settings are stored in the 
detector’s nonvolatile memory. 

1.  Press the programming button three times. 

2.  Wait until the programming LED turns off. 

3.  The programming LED flashes once to show that the 

current value is off. 

4.  Press the programming button twice. 

5.  The programming LED flashes twice showing that the new 

value has been stored. The detector returns to normal 
operation.
