Frequently Asked Questions
Q: What is the detection range of this touchless exit switch?
A: The Asia-Teco 28NT-W infrared touchless exit switch detects a hand or object within a range of 5 to 10 cm. This short, precise detection range minimises false triggers while ensuring reliable, hands-free activation every time.
Q: Is this touchless door exit button suitable for outdoor use?
A: Yes. The switch carries an IP68 waterproof ingress protection rating, meaning it is fully protected against dust and continuous water immersion — making it well-suited for outdoor gates, car-park barriers, and exposed door frames in all weather conditions.
Q: What access control systems is it compatible with?
A: The 28NT-W provides standard NO (Normally Open), NC (Normally Closed), and COM (Common) relay output contacts, which are compatible with the vast majority of commercial and residential access control systems, electromagnetic locks, electric strikes, and gate controllers operating on DC 12V.
Q: How do I know if the sensor has detected my hand?
A: The switch features three built-in LED indicators: a Blue LED illuminates during standby/power-on, and a Red LED lights up the moment the sensor detects an approaching hand within range — providing clear, instant visual confirmation of activation.
