Motion, presence and safety sensor for automatic industrial doors


BEA’s LZR-WIDESCAN is a LASER-based, time-of- flight sensor used for motion, safety and presence detection in a variety of industrial door applications. This all-in-one solution offers the benefits of activation and safety, while reducing installation time.

This NEMA 4 rated sensor creates a volumetric detection area by generating seven angled LASER curtains. It has the ability to detect objects based on direction, speed, object size and height.

The LZR-WIDESCAN detection field operates independent of ground conditions, allowing for superior functionality in harsh environments.


Alternative Solution

Ideal for replacing costly / labor-intensive induction loop and pull-cord solutions


Promotes energy savings by reducing false detections / unnecessary door cycling, helping to regulate HVAC

Virtual Pull-Cord

Virtual pull-cord function can differentiate between pedestrian and vehicle traffic and can provide pulse-on-stop activation

Visible Spots

Two visible LASER alignment spots ensure accurate pattern placement

Frequently asked questions

Which output is used for each of the detection fields?

The outputs can be assigned to each field (motion, presence, safety) as desired.


Can the LZR-WIDESCAN be set to ignore pedestrian traffic moving through the area but allow for pedestrians to open the door if they want to pass through?

Yes, using the virtual Pull-Cord function. Up to 3 locations can be set for a pedestrian to activate the door by standing in the preset locations for X number of seconds. The same principal can be applied for vehicles.


Can the LZR-WIDESCAN be used in a freezer application?

Yes, and the sensor even has a built-in heater to help keep the lens defrosted.


Can the LZR-WIDESCAN send different outputs depending on the height of the object, such as partial open for pedestrians and full open for trucks?

Yes, the LZR-WIDESCAN can be set to detect pedestrians and be wired to the Partial Open input of the door control and the Height Trigger can be wired to the Full Open input.  Remember that when using Height Trigger, pedestrians will have to be closer to the door to be detected.


Why does the LZR-WIDESCAN quickly blink red when programming?

A lock code has been entered. Cycle the power, and then press UNLOCK > LOCK > 0000 to clear the lock code.


How far from the door can the field of detection extend?

The ratio of mounting height to detection distance is 1:1.2. For example, mounting the sensor at 10 feet high will create a maximum pattern size of 12 feet by 12 feet.


Where is the LZR-WIDESCAN pattern oriented?

Press UNLOCK > MAGIC WAND > MAGIC WAND. Two visible laser beams will appear to align the sensor pattern in close proximity to the door.


Why is the LZR-WIDESCAN holding the door open even though it is not in detection?

Verify relay output setting.


I only have a need for two detection fields. How can I eliminate one of the fields and its associated LED?

Simply set that detection field’s width to 000.


Do I have to connect the monitoring wires (similar to the LZR-I30) for non-monitored applications?
