SMS SenTRI Sounder & High Power VAD
Summary
The SMS SenTRI SEN-S-VAD-HPW-R and SEN-S-VAD-HPR-R are combined sounder and VAD (Visual Alarm Device) beacon units designed for use with the SMS SenTRI addressable fire alarm system. These wall-mounted devices feature a red body construction with either white high power flash (HPW-R) or red high power flash (HPR-R) beacon through a clear lens, providing both audible and visual alarm capabilities in a single compact unit.
Both models offer the same core functionality with the key difference being VAD colour – white flash for enhanced visibility and contrast in most environments, or red flash following traditional fire alarm colour conventions. The white VAD option provides superior visibility against varied backgrounds and lighting conditions, while the red VAD maintains consistency with traditional fire safety colour schemes and immediate recognition as fire safety equipment.
As part of the SenTRI intelligent detection range, these devices communicate directly with the fire control panel via an addressable loop, allowing precise device identification and control. The units streamline installation by combining essential alarm functions while maintaining aesthetic appeal through compact design, reducing both installation complexity and overall system costs.

FAQs
What is the difference between the HPW-R and HPR-R models?
The key difference is the VAD beacon colour. The SEN-S-VAD-HPW-R features a white high power flash beacon, while the SEN-S-VAD-HPR-R features a red high power flash beacon. White VADs typically provide better visibility and contrast in most environments, while red VADs follow traditional fire alarm colour conventions and are immediately recognizable as fire safety devices.
Which VAD colour should I choose for my application?
Choose white VAD (HPW-R) for maximum visibility and contrast in general applications, particularly where high ambient light levels exist or varied background colours are present. Choose red VAD (HPR-R) where traditional fire alarm colour schemes are required, consistency with other red fire safety equipment is important, or specific regulations mandate red visual alarms.
Can these devices operate independently of a fire control panel?
No, both models are addressable devices that require connection to a compatible SMS SenTRI fire alarm control panel. They are loop powered and communicate via the addressable loop for control, monitoring, and emergency activation.
What are the installation requirements for wall mounting?
Both devices are designed for wall mounting and require connection to the addressable loop circuit. Installation should be carried out by qualified fire alarm engineers in accordance with BS5839 and EN54 standards, ensuring proper positioning for both audible and visual alarm effectiveness. Consider mounting height, coverage patterns, and ambient lighting when positioning VAD devices.
How many devices can be connected on a single loop?
Multiple devices can be connected on the same addressable loop, each with its own unique address. The loop capacity depends on the control panel and loop card specifications, with each device drawing power from the loop. Refer to the specific control panel documentation for maximum device loading.
Are these devices suitable for outdoor use?
The standard models are designed for indoor applications. For outdoor or harsh environment applications, consider the EP (IP66) rated versions which provide enhanced environmental protection against moisture and dust ingress.
