Frequently Asked Questions
- How close does a hand need to be to trigger the sensor?
The detection range is adjustable from 4 to 15 cm. Set it shorter in tight spaces to reduce false triggers. - Can I wire this as Normally Closed or Normally Open?
Yes. The relay provides Normally Open, Normally Closed, and Common terminals. - What is a common installation mistake to avoid?
Setting the detection range too long can cause unwanted activations from people walking past. Adjust the range and confirm the sensor faces the approach direction.
Additional Information
- Mullion plates are commonly chosen where door frames are narrow and an ANSI plate would not fit.
- Toggle mode can be useful for special applications, but most request-to-exit installations use a short trigger timer so the door relocks automatically.
- If surface mounting and cabling is not recessed, an optional metal back box can simplify mounting and cable management.
