Figure 12 shows the pattern for the maximum range in the 

optimum position (see Figure 10). Masking the top section 

of the lens reduces the range to 20m. 

Figure 13 shows the pattern for the minimum range (10m). 

In this case masking the top section of the lens reduces the 

range to 6 meters. 

Figures 14 and 15 illustrates alignment recommendations 

for when the detector is mounted close to a wall. 

The alignment shown in Figure 14 is not recommended. If 

the detector module is orientated at an angle of 90° to the 

perimeter, the mounting wall may cut off short and medium 

range beams. The long range beam will still detect an 

intruder, however the wall can cause false alarms when 

heated by sunlight. 

Figure 15 shows the recommended alignment. The detector 

module is orientated 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 metres. 

The user can individually programme a number of 

configurable settings, as illustrated in the programming 

chart.

Programming

4. Press the programme button twice to change the 

setting to ON.

5. The indicator blinks twice and the changes are 

stored in the D-Tect 1's non volatile memory.

Walk Test

In walk test mode, the detection LED option is set to ON, 

and the pulse count option is set to 1. The detection LED 

lights each time the D-Tect 1 detects your presence. 

To enter the walk test mode, press the programming button 

once. The detection LED lights and pulse count 1 is 

automatically selected. The unit can then be aligned.

The test mode ends automatically five minutes after last 

detection. Alternatively, press the program button three 

times, or remove and then reapply power to cancel the walk 

test mode. 

Note: When you conduct a walk test, make sure that the 
front cover is in place. Do not conduct walk tests with 
the cover removed. 

The range of the detector increases without the protective 

front cover. Therefore the front cover must be fitted to 

establish the correct beam pattern. Use programming chart 

to adjust the range as necessary. Pan and tilt the lens 

module over the field of view to obtain the correct coverage 

area.

Shaded settings are factory defaults

To change any of the D-Tect 1 settings:

1. Press the programme button, as shown in figure 

16, for the number of the Option to be changed, i.e. 

once for range, twice for pulse count and three 

times for LED.

2. Wait until the blue LED indicator goes off (typically 

four seconds).

3. The indicator will then flash out the existing 

settings.

4. To change the settings for that option, press the 

programme button the number of times for the 

required new setting.

8. The indicator blinks twice and the changes are 

stored in the D-Tect 1's non volatile memory.

Example: To change the LED setting from OFF to ON:

1. Press the programme button twice.
2. Wait until the blue LED indicator goes off (typically 

four seconds).

3. The indicator will then flash once, indicating the 

current LED setting is OFF.
