Programming
The user can individually program a number of congurable
settings, as illustrated in the programming chart below using the
program button and LED shown in Figure 4.
The factory default settings are set to suit the most popular
applications but can be changed to suit individual requirements,
either before installation or on-site. Once changes have been
made they are stored in a non-volatile memory.
The default factory settings for the D-Tect X MKIII detector are
as follows:
Range 50 metres (15 minute supervision)
Pulse Count 1
Lux 5
Timer (seconds) 5
To change factory default settings, proceed as follows:
1. Press the ‘Program Button’ the required number of times
to access the setting/mode that needs changing and a
red LED will illuminate (see following information and
programming chart)
Once - transfers code
Twice - sets detector range in metres
Three times - sets the pulse count
Four times - adjusts LUX level
Five times - sets alarm activation time in seconds
Six times - shows existing settings
Seven times - resets detector to factory settings
Eight times & hold down - starts RF continuity test
Nine times & hold down - generates new random
communication code

To re-set the default settings remove the batteries, wait 10
seconds, press and hold the program button then re-t the
batteries, the LED will ash rapidly then release the program
button.
2. When the ‘Program Button’ has been pressed the required
number of times, wait 4 seconds until the red LED
indicator goes off.
3. After a short delay, the LED will then ash a number of
times to indicate the existing setting (eg in detector range
mode, 3 ashes will show that the existing range has been
programmed to 50 metres with a 15 minute supervision
timer)
4. To change the setting for that option – wait until the
LED stops ashing then press the ‘Program Button’ the
number of times needed to program in the new setting (eg
pressing the button twice in range mode will change the
setting to 40 metres with a 15 minute supervision timer).
The LED will blink twice to indicate that the new setting
has been saved.
Functions
Range settings are self explanatory but for reference, other
settings/modes are dened below:
Pulse Count (1, 2) – this is the number of times the unit has
to detect an intruder on both of its sensors before signalling an
activation. The range of the detector will decrease if there is little
difference in temperature between the moving object and the
background.
1 – will give a fast response
2 – gives better immunity with good response
LUX ‘S’ Output only – 7 settings from 2 to 50 lux – the 8th
setting is the 24 hour mode.
a) LUX – is a measurement of ambient light levels that must be
reached before the ‘S’output will become active when there is an
activation of the detector (2 is night and 50 is lighter).
b) 24 HOUR – the detector will operate the ‘S’ output day and
night, irrespective of light levels. All other outputs operate day
and night irrespective of the ‘S’output setting.
TIME ‘ALARM’ OUTPUT TIMER
This is the active time in seconds that the ‘alarm’ volt free output
will activate for after an activation of the detector.
Rf Continuity Test
It is always advisable to test the RF signal at the detector location
prior to installation.
To enter the RF continuity test mode – press the ‘Program Button’
on the D-Tect X MKIII 8 times.
On the 8th press – ‘hold’ down the ‘Program Button’ for 5
seconds until the LED goes off – the LED indicator will then ash
and transmit one signal per second to the receiver.
The corresponding Channel Indicator on the receiver module will
also ash once per second if a strong enough RF link has been
established.
This test mode will automatically cancel after ve minutes.
Alternatively, to cancel the RF continuity test immediately – press
and hold the ‘Program Button’ until the LED illuminates then
release the button.
Register one detector as described in ‘Code Learning’, then
conduct an RF continuity test as detailed above. As the signals
to the receiver are sent once per second, the optimum position of
both the D-Tect X MKIII detector and the receiver box can easily
and quickly be established.
Changing The Random Code
In the unlikely event of another radio signal interfering with
and affecting the correct operation of a single RF channel, the
D-TectX30 MKIII is able to generate an alternative random code.
To do this, press the Program Button on the D-Tect X MKIII nine
times. On the ninth press, ‘hold’ down the button for 5 seconds
until the LED goes out, then release the button.
Erase the existing code from the receiver by holding down the
Channel Button until the alarm LED ashes, then repeat steps
3 to 6 of the CODE LEARNING procedure to program in the new
code.
