What Are Door Interlock Accessories?

Accessories bridge the gap between operators and your interlock controller. The controller manages sequencing, while accessories facilitate operator interaction and provide crucial visual feedback. Common accessory types include:

• REX buttons: These devices offer operator control for door access in both automated and manual interlock scenarios. REX buttons are ideal for commercial and industrial applications.
• Emergency override switches: Manual controls allow critical door operation during emergencies.
• LED indicators: These are clear visual signals that communicate immediate door status to operators.
• Touchless wave sensors: These hands-free devices detect hand movements within a 4-inch range, offering hygienic activation. Specialized for contamination-sensitive environments like hospitals and cleanrooms, they help prevent the spread of infection by eliminating surface contact.
• Audible alarms: Audio notifications alert personnel to critical door events and status changes.

What Is a REX Device?

A REX device allows authorized personnel to initiate door release while ensuring your interlock controller maintains proper sequencing. Both push-button REX devices and touchless wave sensors perform this function.

REX Buttons vs. Touchless Door Sensors

REX buttons and touchless wave sensors serve the same purpose but address different operational priorities. Traditional REX buttons offer several advantages:

• Durable operation: The physical press confirms activation and provides clear feedback.
• Proven reliability: REX buttons perform consistently in commercial and industrial environments.
• Minimal maintenance: Their simple, robust mechanical design ensures consistent long-term operation with minimal upkeep.

Touchless wave sensors provide distinct benefits:

• Contamination reduction: Touchless operation aligns with stringent hand-hygiene best practices in sensitive environments. In pharmaceutical gowning rooms, touchless sensors prevent glove contamination before personnel enter sterile corridors.
• Surface contact elimination: Sensors eliminate contaminant transfer associated with repeated surface contact.

Other Door Interlock Accessories

Additional accessories strengthen system awareness and emergency response. Careful selection ensures alignment with your operational needs.

LED Status Indicators

These lights provide clear, real-time communication of door status. Red and green illumination offers immediate feedback on conditions such as locked, unlocked, occupied or safe to enter.

Emergency Override Switches

Emergency override switches offer controlled manual operation during emergencies. These switches integrate with fire alarm systems to meet life-safety requirements. When a hospital wing activates its fire alarm, emergency override switches automatically release interlocked doors to ensure code-compliant egress.

Audible Alarms

Audible alarms notify personnel of door status changes and unauthorized events. Alerts cover door-held-open conditions, sequencing errors and attempted unauthorized access.

Recommended Configurations

Match your facility’s priorities to these proven combinations:

• Basic: REX button + LED
• High-touch: Wave sensor + LED + alarm
• Emergency-ready: REX button + override + LED + alarm
• Cleanroom: Wave sensor + LED + override

Each configuration addresses the specific requirements of different facility types.

Choose the Right Door Interlock Accessories

Your environment determines which accessories deliver the most value.

Healthcare Facilities

Contamination control and patient safety drive accessory selection in healthcare. Touchless activation reduces contact points where hand hygiene impacts outcomes. A typical configuration combines a touchless wave sensor, LED indicator and audible alarm.

Pharmaceutical Cleanrooms

Cleanroom integrity and regulatory compliance determine accessory selection in pharmaceutical manufacturing. Configurations combine touchless sensors, LED indicators and emergency override controls.

High-Security Areas

High-security facilities prioritize controlled operator input. REX buttons provide intentional activation requiring conscious action. Configurations combine REX buttons with emergency overrides, LED indicators and audible alarms.

Standard Commercial and Industrial Facilities

Many commercial environments require straightforward operator control. A REX button, paired with an LED indicator, delivers a dependable solution. These configurations emphasize compatibility with existing systems.
