FireLaser is a Linear Heat Detector System specifically designed for use in Special Hazard fire detection applications.
The FireLaser Distributed Temperature Sensing (DTS) system connects to a distributed fiber optic cable (FireFiber) and determines temperature and distance data at thousands of points along the length of the cable. The fiber optic cable is installed within the asset to be protected and this cable acts as the sensing element. The FireLaser Sensor Control Unit is responsible for generating alarms based upon the calculated temperature profile. The FireLaser DTS can therefore detect the location of a hot spot on up to a 5km length of fiber optic cable with unrivaled precision. The system is able to monitor the movement of the hot spot, or multiple hot spots, in terms of physical position, temperature and also in real-time. FireLaser Distributed Temperature Sensing Technology provides a line type heat detector solution vastly superior to conventional copper based or multipoint heat detector.

Approvals & Testing
Bandweaver is ISO 9001 certified and undergoes a rigorous continuous improvement program and tests all of its products to leading international standards
- Extensive environmental testing on all products
- Components to telecom standards > 25 years MTBF
- Products are designed for low maintenance and cost of ownership (e.g. fan free design..)
Bandweaver tests all of it’s equipment to the highest standards both based on internal specifications and guidelines and also to leading industry 3rd party standards. Bandweaver has extensive internal testing facilities but in addition we also test with internationally leading 3rd party test houses.
T-Laser Technology Principle
The Bandeaver T-Laser Distributed Temperature Sensor (DTS) measures the temperature along the fiber using a technique called Optical Time Domain Reflectometry (OTDR). The DTS rapidly sends laser pulses into the fiber optic and measures the reflected light from the optical fiber sensing cable. By analyzing the scattered light at the Raman frequencies the DTS is able to create a distributed temperature measurement along the entire length of the fiber.
FireLaser Interfaces and System Integration
Bandweaver has operated as a system integrator for more than 10 years and has a full range of services from system design through to installation and commissioning.
We have extensive experiencing in designing our systems to interface with standard industrial formats and specific customer request.
Bandweaver has designed specific customer user interfaces to consolidate, manage and visualize both DTS data (including 3rd party DTS systems) and integrating other data feeds. Equally, Bandweaver is also comfortable exporting data into 3rd party systems and networks. Examples of some of the interfaces Bandweaver has worked with include:
- Modbus / DNP3
- Electrical relay outputs
- OPC / IEC61850 / Generic Object Oriented Substation Events
