Frequently Asked Questions (FAQ)
- How do I wire this into an access controller input?
Use COM with NO or COM with NC depending on whether your controller expects a Normally Open or Normally Closed Request To Exit input. - Can this trigger a magnetic lock or electric strike?
Yes. It provides output contacts (NO, NC, COM) that can be used to trigger an access controller input or directly switch suitable circuits within the contact rating. - Is a back box required?
A back box is not required for all installs. An optional surface mount metal back box (NEMSMB) is available if the mullion cannot be prepared for flush mounting.
Additional Information
- Touch exit buttons are commonly specified on commercial access controlled doors as an alternative to a mechanical Request To Exit button, especially where a stainless mullion plate suits the door style.
- If installing externally, ensure the mounting position and cable entry reduce water exposure and protect the wiring path through the mullion.
- Where false triggers are a concern, installers often confirm the sensor sensitivity and mounting height aligns with the door hardware layout and user approach.
