Scantronic HUD-2R-RMT-LR | Wireless Long Range Hold-Up Device | Man-Down & HUA, Belt Clip

FAQs

What is the advantage of the extended range design?

The HUD-2R-RMT-LR features an enhanced antenna design within its 163mm body, providing superior signal propagation in challenging RF environments such as large facilities, multi-story buildings, or areas with significant structural interference. Whilst both standard and extended range models achieve over 1000m free space range, the LR model’s extended antenna provides additional performance margin in real-world installations where building materials and RF interference may affect signal strength.

What dual-channel capabilities does the HUD-2R-RMT-LR offer?

The transmitter supports two distinct dual-channel configurations: HUA (Hold-Up Alarm) combined with man-down detection for automatic alert if the wearer becomes incapacitated or falls, or HUA combined with an additional action button for pre-warning alerts. This flexibility enables graduated response protocols where staff can signal for assistance before escalating to full alarm activation, or automatic protection for lone workers in high-risk environments.

How does man-down detection work?

When configured with man-down detection, the transmitter monitors the wearer’s orientation and movement patterns. If the device detects a fall or extended period of immobility consistent with incapacitation, it automatically transmits an alarm signal to the control panel without requiring manual activation. This provides critical protection for lone workers who may be unable to manually activate the alarm following an incident.

Why does the HUD-2R-RMT-LR have a non-replaceable battery?

The 3.6V Li 1/2 AA battery is sealed within the unit to maintain optimal RF performance and environmental protection. With typical 3-5 year operational life and intelligent low battery warning providing one month advance notice, the sealed design ensures consistent performance throughout the battery’s lifespan. When battery replacement is needed, the entire unit is serviced, ensuring all components meet original specification standards.

What mounting options are available for the HUD-2R-RMT-LR?

The HUD-2R-RMT-LR is designed for belt mounting, providing secure carrying whilst maintaining the enhanced antenna orientation required for optimal range performance. The 163 x 46 x 30mm dimensions accommodate the extended antenna whilst remaining practical for all-day wear in professional environments.

Is the HUD-2R-RMT-LR compatible with existing Scantronic systems?

Yes, the transmitter supports both advanced SSR communication (868.0-868.6MHz) and backwards compatible narrowband operation (868.6625MHz), enabling integration with existing Scantronic security systems. The SSR protocol provides enhanced security features including encryption and two-way communication, whilst maintaining compatibility with legacy installations. The dual-channel functionality requires compatible control panel configuration to fully utilize man-down or alert features.

What does BS8243 compliance mean for this transmitter?

BS8243 is the British Standard for installation and configuration of personal attack alarm systems. The HUD-2R-RMT-LR complies with BS8243 requirements for both confirmed and unconfirmed alarm transmissions, ensuring it meets professional standards for reliability, signal strength, and operational performance in lone worker protection applications, including man-down detection scenarios.

How does the pre-warning alert function work?

When configured with the additional action button, staff can activate a pre-warning alert signal before escalating to full alarm status. This enables graduated response protocols where security personnel can be notified of potential concerns whilst avoiding full alarm activation unless the situation deteriorates. This functionality is particularly valuable in customer-facing environments where discreet assistance may resolve situations before formal alarm procedures are required.

What is Scantronic Secure Radio (SSR) technology?

SSR is Scantronic’s advanced wireless communication protocol featuring true signal encryption for market-leading cybersecurity protection. SSR provides two-way communication between devices and control panels, enables over-the-air firmware updates, and delivers shortened response times for improved battery life and rapid event notification whilst minimizing false alarms. The encryption ensures transmitted signals cannot be intercepted or spoofed, critical for personal safety applications.
