BEA 10SSTI42, SuperScan I, 42" Length 1 Primary only
The BEA 10SSTI42 is a SuperScan I primary active infrared presence sensor built for automatic pedestrian door safety and presence detection. This 42 inch version is ordered when the door width, sensor housing, and installed BEA SuperScan I system call for that exact length. Mounted on the door or header area depending on the application, the sensor uses distance-measuring active infrared detection to monitor the area around the moving door and help the operator react while a person or object is in the pattern. In service work, the most common ordering mistakes are choosing the wrong length, confusing primary and secondary units, or substituting a different BEA sensor family by appearance alone.
BEA’s SUPERSCAN-T INDUSTRIAL is an active infrared sensor designed for use in industrial environments that require presence and/or safety detection. This sensor can be used on automatic industrial doors, gates and industrial automation applications.
The SUPERSCAN-T INDUSTRIAL uses triangulation to detect the presence of an object, eliminating false detections caused by varying ground and environmental conditions.
In an industrial setting, this versatile sensor can be mounted stationary or on a moving object. Additionally, the SUPERSCAN-T INDUSTRIAL can be used as an individual module or daisy chained with up to 8 Secondary modules (9 total modules). This flexibility allows the SUPERSCAN-T INDUSTRIAL to be used on both narrow and wide doors and many other off door applications. Each module detection zone can be angled independently.

Technician Note
Match the sensor length and primary/secondary configuration before ordering. A SuperScan I primary module should not be swapped with a secondary module or a different sensor family unless the door system is being redesigned and tested.
Before Ordering
- Confirm the installed BEA part number and housing length.
- Verify the row is for a primary sensor only.
- Check whether the door also uses secondary or slave modules.
- Confirm the door type and door width reference.
- Inspect wiring and harness connections before replacement.
- Perform a complete safety and activation test after adjustment.
Important Ordering Warnings
- Do not assume SuperScan I, SuperScan II, Quadscan, and LZR-FLATSCAN sensors are interchangeable.
- Changing the sensor length can change coverage and may require a new safety setup.
Professional Advisory
Automatic pedestrian door sensors and wireless controls should be installed, adjusted, and tested by a qualified automatic door technician. Do not use an activation sensor as a substitute for required presence, safety, or monitored protection devices.
Product Questions & Answers
What is the 10SSTI42 used for?
The 10SSTI42 SuperScan I is a door-mounted active infrared presence sensor for compatible automatic swinging, revolving, folding, and low-energy door applications.
Is this a primary sensor only?
Yes. The uploaded item is identified as one primary SuperScan I module. Secondary modules or additional housings are separate unless the listing states otherwise.
Can SuperScan I sensors be daisy chained?
SuperScan-T style sensors are commonly used individually or daisy chained with additional slave modules where the door width requires broader coverage.
Is this the same as SuperScan II?
No. SuperScan I and SuperScan II are related BEA sensor families but should not be treated as interchangeable without checking the installed system and wiring.
How do I choose the correct length?
Match the original BEA part number, housing length, and door width reference. A different length can affect mounting, coverage, and appearance.
