How to correctly install the WX Series detection sensor
The OPTEX WX series includes the WX Infinity (WXI) and WX Shield (WXS) outdoor PIR detection sensors. These sensors provide two independent left-right detection areas up to 12m each (24m in total) with separate sensitivity and range adjustment, enabling the detector to adapt to the areas of interest reducing nuisance alarms.
Once the mount height is chosen, it is important to set the detector setting to the correct mount height.
Use the blue handle in the middle of the upper sensors to pull up or push down the front frame to reveal the mount height setting, “HIGH MNT” or “LOW MNT” will be visible to indicate the current detector mount setting.
Step 4 – Adjusting the sensor settings
Configurable elements in WX series are easily recognisable as they are all in blue.
Using the DIP switches you can adjust the settings to suit the detection requirements. Please take special note with DIP switches 3, 9 and 10 relating to the individual adjustments for left/right sides of the detection:
- It is important to consider if the left and right detection zones will output as a single alert output or separately and set DIP switch ❸ accordingly.
- For dual tech models with microwave, when the detection range is adjusted, the microwave detection range will need to be changed in DIP switches ❾ and ❿.
DIP switches
❶LED
ON: LED is activated according to the sensors status.
OFF: LED is not activated except during warm-up and walk test.
❷Alarm output type
ON: Alarm (L) and (R) = N.O. (Normally Open)
OFF: Alarm (L) and (R) = N.C. (Normally Closed)
❸Individual outputs
ON: Alarm (L) and (R) output alarm signals individually without affecting each other.
OFF: Alarm (L) and (R) output alarm signals at the same time by either detection alone.
Individual outputs ON/OFF by DIP SW No.3
❹Pulse count
ON: Pulse count setting = 1
OFF: Pulse count setting = 2
❺PIR immunity
ON: Immunity
OFF: Normal
‘Immunity’ is used under harsh environments, ‘Normal’ is used under standard conditions.
❻Battery saving timer
ON: timer period = Five seconds
OFF: timer period = Two minutes
Even if there are continuous alarm events, the alarm is generated only once in the timer period to save the battery life.
❼Day/Night
ON: Night only
OFF: Day and Night
Alarms output only when ambient illuminance becomes dark by switching to ‘Night only’.
Alarms output any time by detecting in ‘Day and Night’.
❽Anti-masking
ON: Anti-masking ON
OFF: Anti-masking OFF
When masking condition continues for more than three minutes, a ‘Trouble’ warning will be generated. Trouble is generated after 20 seconds under the anti-masking test mode.
Depending on the model use these dip switches to customise the detector performance to best suit the site.
Notable settings are PIR sensitivity and detection range
❾Microwave range (Left)
❿Microwave range (Right)
ON: Long
OFF: Short
Switch the microwave detection distance to ‘Long’ and ‘Short’.
Long: low mount 12m; high mount 9m
Short: low mount 9m; high mount 6m
⓫Microwave immunity
ON: Immunity
OFF: Normal
‘Immunity’ is used under harsh environments, ‘Normal’ is used under standard conditions.

Step 5 – Walk Test
When the front cover is closed the WXS detector will automatically switch to walk test mode for three minutes. During this test, the sensors LED will come on for two seconds when an object is detected. The LED will blink for five seconds at the end of the automatic walk test and the sensor will back to normal operation mode.
Following the walk test, make any adjustments as required and repeat if necessary.
