SMS SenTRI Addressable Heat Detector with Sounder
£78.83 (inc VAT: £94.60)
Summary
The SenTRI Addressable Heat Detector with Sounder offers intelligent fire detection and audible warning in a single, compact unit. Designed for areas where smoke detection may be unsuitable, it uses advanced heat sensing to accurately identify fire conditions while reducing false alarms. A built-in sounder provides clear, localised alerts without the need for additional alarm units, streamlining installation and minimising visual disruption.
Each SenTRI device includes a built-in isolator, enhancing system integrity and saving costs by removing the need for separate isolators. The detector also features a monitored input/output line, configurable as a fire input or output, potentially eliminating the requirement for additional interfaces.
As part of the SenTRI intelligent detection range, the SenTRI Addressable Heat Detector with Sounder communicates directly with the fire control panel via an addressable loop, allowing precise device identification and rapid response. This high-performance device combines advanced heat sensing technology with a built-in sounder, reducing the need for separate alarm components and streamlining installation.

FAQs
What makes this detector suitable for areas where smoke detection is inappropriate?
The SenTRI uses advanced heat sensing technology specifically designed for environments where smoke detectors may cause false alarms or be unsuitable, such as kitchens, workshops, or dusty areas. Heat detection is more reliable in these conditions while maintaining accurate fire identification.
How does the built-in isolator benefit the system?
The built-in isolator enhances system integrity by preventing faults from spreading along the loop while saving installation costs by eliminating the need for separate isolator units. This streamlines the installation process and reduces component requirements.
What are the 3 levels of alarm?
The detector features multiple alarm levels that provide graduated response capabilities, allowing for appropriate escalation based on the severity of the detected conditions. This enables more nuanced fire safety responses tailored to different threat levels.
Can the device operate independently or does it require a control panel?
The SenTRI is an addressable device that communicates directly with a fire control panel via an addressable loop. While it includes a built-in sounder for immediate local alerts, it is designed to work as part of a complete addressable fire detection system.
What is the sound output level and is it suitable for occupied areas?
The device produces typically 90 dB(A) at 1 metre, which provides clear audible alerts while being appropriate for occupied spaces. The localised sounder ensures immediate notification in the area of detection.
