Request-to-Exit Sensors

Request-to-exit sensors replace mechanical push-to-exit buttons with hands-free motion detection technology. These PIR devices automatically trigger door release when occupants approach, meeting NFPA-101 egress requirements while preventing hallway false alarms

Hands-Free Egress Technology for Modern Facilities

Access control installations increasingly demand REX devices that balance occupant convenience with regulatory compliance. These motion-activated systems use passive infrared technology to sense approaching individuals, automatically releasing electric strikes or magnetic locks without requiring contact with traditional exit buttons.

PIR Detection and Beam Configuration

Request-to-exit units employ narrow-beam infrared sensing with depth limitations under 4 feet, preventing unwanted activation from distant corridor movement. The passive infrared components focus detection within the immediate egress zone while maintaining reliable triggering for legitimate exit attempts.

Both Seco-Larm and Securitron models feature adjustable sensitivity settings and programmable timer functions ranging from 1–30 seconds. Walk-test LED indicators assist with proper aiming during installation, while selectable illumination modes accommodate various operational preferences.

Facilities that still want a manual backup can wire companion request-to-exit buttons in parallel with the PIR relay, giving staff both touch-free and traditional egress options.

Electrical Integration and Contact Configuration

These REX sensors accommodate standard 12/24 VDC auto-sensing power supplies compatible with most door access panels. SPDT and DPDT dry relay contacts provide normally open and normally closed terminals for diverse locking mechanisms including electromagnetic hardware and electric strike assemblies.

Installation methods include:

  • Single-gang mounting for retrofit applications
  • Surface adhesive attachment for quick deployment
  • Tamper switches on select models for security monitoring

To create a completely turnkey solution, drop this PIR head into one of our single-door access control kits so the controller, reader, power supply, and REX device arrive pre-matched.

Compliance Standards and Safety Protocol

Professional-grade request-to-exit devices meet UL 294 and ULC-S319 listings where applicable, conforming to ANSI/BHMA A156.7 REX requirements. Building codes favor touchless egress solutions, particularly in healthcare environments and clean-room applications where contamination concerns mandate hands-free operation.

The narrow detection pattern prevents false triggering from hallway traffic while ensuring adequate coverage for wheelchairs and mobility devices. Timer-controlled lock release maintains security protocols while providing sufficient egress duration for ADA compliance.

If the opening already uses a panic bar, pair the sensor with motor-driven ELR kits so the latch retracts automatically the moment motion is detected.

Frequently Asked Questions

What voltage do request-to-exit sensors require?

Most REX sensors feature 12/24 VDC auto-sensing power supplies, making them compatible with standard access control panels without additional voltage conversion equipment.

How do PIR motion sensors prevent false alarms?

Narrow-beam detection patterns limit sensing depth to under 4 feet, focusing coverage on the immediate egress zone while ignoring distant hallway movement.

Can these sensors work with existing electromagnetic locks?

Yes, SPDT and DPDT relay contacts accommodate electric strikes, magnetic locks, and other electromagnetic locking mechanisms through normally open/closed terminal configurations.

Do request-to-exit devices meet building code requirements?

UL 294 and ANSI/BHMA A156.7 listed models comply with NFPA-101 egress standards, making them suitable for commercial and healthcare facility installations.

What timer settings are available for lock release duration?

Adjustable timer functions typically range from 1–30 seconds, allowing customization of lock release duration to meet specific security protocols and ADA requirements.
