Alarm Controls NTB-3A Battery Operated No Touch Sensor, Narrow Stile with ADA Symbol

Optimize access control with the Alarm Controls by ASSA ABLOY NTB-3A, a battery-operated no-touch Request-to-Exit device engineered for safer, more hygienic egress. This touch-free sensor replaces traditional push buttons, delivering hands-free operation that supports ADA compliance and reduces surface contacts — ideal for healthcare, education, retail and corporate security environments. The NTB-3A uses infrared detection with a precise 4-inch activation range, field-configurable 1–10 second timer and built-in obstruction detection to ensure dependable performance and minimize false activations. Its vandal-resistant stainless steel faceplate (screened “Wave to Open”) and bi-color LED status indicators simplify installation verification and daily monitoring. Battery power with optional DC input and wired communication makes the unit simple to integrate into existing access control, surveillance and monitoring systems without expensive door work. Designed by Alarm Controls (ASSA ABLOY), the NTB Series gives facility managers a cost-effective way to upgrade to touchless egress while maintaining high physical security standards. Contact your distributor or order the NTB-3A to upgrade doors to a safer, code-compliant touchless solution.
