Protection at the blind point
Install the warning unit at an aisle corner, doorway or other crossing where a forklift may emerge without a clear line of sight.
SF-540 UWB Forklift Blind Zone Warning System
A blind corner gives people little time to react to an approaching forklift. The WTSAFE SF-540 places a voice and flashing-light warning at the crossing itself: when a tagged forklift approaches the configured area, the local alarm alerts people nearby before the vehicle comes into view. It is designed for warehouse aisle ends, doorways and other fixed points where sight lines are blocked.

SF-540 UWB Forklift Blind Zone Warning System FAQs
Q: What is the SF-540 UWB Forklift Blind Zone Warning System?
−
−
A: The SF-540 is a fixed-area warning system for places where a forklift may approach out of sight, such as a warehouse corner or doorway. A warning unit at the risk point responds to a compatible tag on the approaching forklift and alerts nearby people with a voice message and flashing light.
Q: How is the SF-540 different from an onboard forklift proximity alarm?
+
+
A: The SF-540 is arranged around a specific crossing or blind zone. Its fixed warning unit alerts people at that location when a tagged forklift approaches. An onboard proximity system instead travels with the forklift and monitors nearby compatible tags as the vehicle moves through the site.
Q: Where should the SF-540 warning unit be installed?
+
+
A: Typical locations include rack-end blind corners, T-junctions, building entrances and exits, and crossings between forklift routes and pedestrian areas. The mounting position and warning distance should be checked against actual traffic directions and sight lines on site.
Q: What happens when a tagged forklift approaches the warning area?
+
+
A: The fixed unit detects the approaching vehicle tag within the configured warning area and activates its voice alarm and flashing warning light. This gives people near the crossing a prompt to look for the forklift and keep clear of its path.
Q: What is the SF-540’s warning distance?
+
+
A: The published SF-540 area warning distance is 1–15 m. The appropriate setting depends on the approach speed, route geometry, mounting location and available stopping distance; it should be verified during installation.
Q: Can the SF-540 detect a person without a tag?
+
+
A: The tag-based configuration should not be described as detecting every untagged person. Personnel-specific detection and warning require a suitable configuration with compatible personnel tags. If detection of untagged pedestrians is required, ask WTSAFE to assess another sensing method or a combined solution.
Q: Does the SF-540 automatically slow a forklift?
+
+
A: The SF-540’s published core function is area monitoring with voice and light alarms. Vehicle speed-control linkage may be specified as part of a compatible project configuration; it should not be assumed to be included with the warning unit alone.
Q: Can the system warn about both forklifts and pedestrians?
+
+
A: A solution equipped with compatible vehicle and personnel tags can be configured for different approach situations, including vehicle movement, personnel movement and convergence at a crossing. The exact alert logic and included tags should be confirmed for the selected installation.
Q: What power supply does the SF-540 warning unit require?
+
+
A: WTSAFE’s published specification lists AC 220 V for the SF-540 warning unit. Power requirements for vehicle tags, personnel tags or optional accessories are separate and depend on the components selected.
Q: What information is needed to plan an SF-540 installation?
+
+
A: Provide a floor plan or photos of the blind point, traffic directions, doorway or aisle dimensions, forklift quantity and whether workers will carry tags. Also identify any requirement for speed-control linkage or projected floor warnings so the complete configuration can be confirmed.
