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

Option
1. Range (m)
2. Pulse count
3. Detection LED
* Default settings
To change any of DDI602AM settings:
Note: Only the top PCB red LED is used in programming the
detector.
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
press three times.
The programming LED blinks twice to indicate that the
new value was set.
Any alterations made to DDI602AM 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.
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.
Resetting options
To reset the detector to the default settings:
1. Remove the power from the detector.
2. Press and hold the programming button (see Figure 16,
item 2).
3. Apply the power to the detector.
4. After the programming LED flashes, release the
programming button.
You can reset the detector either before installation, with a PP3
battery, or by applying 12 V to the unit on site.
Walk test
In walk test mode, the blue detection LED option is set to ON.
The detection LED lights each time the DDI602AM detects
your presence.
To enter the walk test mode, press the programming button
once. The unit can then be aligned. The detection LED lights
on the DDI602AM every time detection takes place.
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.
Caution: 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 Table 3 to adjust the
range as necessary. Pan and tilt the lens module over the field
of view to obtain the correct coverage area (see Figure 8).
Fault/Anti-Mask Circuit
Fault/Anti-Mask technology prevents deliberate disabling of the
detector by monitoring for obstruction of the detection
equipment.
Operation
For the first two minutes after the sensor is installed or the
walktest is started the Fault/Anti-Mask relay can remain open.
After installation the detector needs to self-calibrate and this is
done by entering walk test mode. After 2 minutes of selecting
walk test the Anti-Mask will self-calibrate so the front cover
must be securely fitted. After 5 minutes of selecting walk test
the test will end.
After a Fault/Anti-Mask has been detected constantly for one
minute then the Fault/Anti-Mask alarm contact opens and
remains open until either the cause of masking is removed or
the detector performs a successful self-calibration.
If an internal fault condition is detected then only the Fault/A-M
relay operates. However in an Anti-Mask conditions both the
