SPECIALIST FIRE DETECTION SYSTEMS | ESTABLISHED 1966
Aspirating Smoke & Beam Detection Systems
J. Shaw Group provides specialist aspirating smoke detection and optical beam detection solutions for commercial, industrial and high-risk environments across Greater Manchester and the UK. From early-warning smoke detection in data centres and critical infrastructure to optical beam detection for warehouses, distribution centres and large open spaces, our experienced team delivers professional installation, testing, commissioning and maintenance services.
Advanced Fire Detection
for Critical Environments
Traditional point-type smoke detectors are not always the most suitable solution for large buildings, high ceilings or environments requiring particularly early detection.
J. Shaw Group provides specialist fire detection systems designed around the specific risks, layout and operational requirements of each premises.
Our solutions include aspirating smoke detection systems, which continuously sample air through dedicated pipework, and optical beam smoke detectors, which monitor large open areas for smoke obscuration.

what amazing lads! from start to finish first class workmanship friendly high standard of work carried out on my property 5 star to this company
Christine Perry, Manchester

The process of receiving the quotation provided me with the confidence that the company understood the needs of my none-standard installation, they provided all the necessary details and costs. The Installer (Chris) ensured good communication prior to and during the installation; he undertook the work professionally and ensured we were happy with the work prior to completing each of his tasks. As a Project Manager involved in Construction I was very impressed
John Pearson, Bury

Excellent company to deal with. They were very quick to respond to my initial enquiry and equally prompt in providing clear and helpful updates throughout. The work was carried out in an efficient, friendly, and high-quality manner. Pricing was clearly explained from the outset and did not change. I’ve been very pleased with the professional and friendly way I was dealt with throughout.

Aspirating & Beam Detection FAQs
Have questions about specialist fire detection systems? Find answers to common enquiries about aspirating smoke detection, optical beam detectors, installation, servicing and maintenance with J. Shaw Group.
What Is Aspirating Smoke Detection and How Does It Work?
Aspirating smoke detection systems continuously draw air through a network of sampling pipes into a highly sensitive smoke detector. This allows smoke particles to be identified at an early stage, making the technology particularly suitable for data centres, server rooms, critical infrastructure and other environments requiring early warning of developing fire conditions.
What Is Optical Beam Smoke Detection?
Optical beam smoke detection uses a projected light beam to monitor large open areas for smoke. When smoke enters the beam path, it reduces the received light intensity, allowing the detector to identify a potential fire condition. Beam detectors are commonly used in warehouses, industrial buildings, atriums and other premises with high ceilings.
What Is the Difference Between Aspirating and Beam Detection?
Aspirating smoke detection actively samples air and can provide very early warning of smoke, making it suitable for sensitive and critical environments. Optical beam detection monitors a defined beam path for smoke obscuration and is often more practical for covering large, unobstructed spaces. The most suitable technology depends on the building layout, environmental conditions and fire detection requirements.
Can These Systems Connect to an Existing Fire Alarm System?
Yes. Many aspirating smoke detection and optical beam detection systems can interface with existing conventional or addressable fire alarm systems. Compatibility depends on the existing control equipment, system configuration and applicable design requirements. We can assess the installation and recommend an appropriate solution.
