Why Door Position Switches & REX Sensors Matter (and Stop Nuisance Alarms)

Quick intro: These two tiny devices make your access system feel “smart.”

The teamwork

• Door Position Switch (DPS): Tells the system if the door is open or closed.

• Request‑to‑Exit (REX): Tells it a valid exit is happening, so the lock releases and no “forced door” alarm is generated.

Results you’ll notice

• Fewer false “door forced/held” alarms

• Cleaner reports for audits (you’ll see real tailgating vs. normal exits)

• Smoother auto‑unlock schedules that match actual use

Tip: If deliveries hold the door longer, we’ll extend the held‑open timer for that door only.
