Fiber Installation
A suitable fiber optic sensing cable is installed along the protected route, asset or facility.
FOTAS APEX
Linear Heat DetectionContinuous, real-time temperature monitoring and localized fire detection along optical fiber sensing routes.
CONTINUOUS FIRE AND HEAT MONITORING
Transform Safety and Monitoring with Fiber Optic Linear Heat Detection
FOTAS APEX is a next-generation Distributed Temperature Sensing solution designed for continuous linear heat detection and fire monitoring.
An optical fiber sensing cable is installed along the area to be protected. The APEX controller continuously analyzes temperature conditions along the sensing route and identifies localized increases, developing hot spots and configured alarm conditions.
Unlike individual point detectors, FOTAS APEX provides spatially resolved temperature information along the full installed fiber route. Unlike conventional binary linear heat detection cables, it provides digital temperature measurements and thermal profiles rather than only an alarm or no-alarm signal.
UNDERSTANDING THE TECHNOLOGY
How FOTAS APEX Works
Laser Measurement
The APEX controller sends laser pulses through the sensing fiber and analyzes temperature-dependent optical backscatter.
Temperature Profile
The system produces a continuous temperature profile along the cable rather than measuring only isolated points.
Alarm and Localization
Abnormal temperature conditions trigger an alarm and identify the affected position along the sensing route.

REAL-TIME THERMAL INFORMATION
Continuous Linear Heat Detection
Continuous Temperature Monitoring
Monitor temperature conditions across the full installed sensing route.
High-Temperature Alarms
Generate alerts when configured temperature thresholds are exceeded.
Rate-of-Rise Alarms
Detect developing thermal events through abnormal rates of temperature increase.
Localized Hot-Spot Detection
Identify where abnormal heating is developing along the sensing route.
Configurable Alarm Zones
Divide the sensing route into project-specific alarm and monitoring areas.
Historical Temperature Analysis
Review temperature profiles and event history for operational analysis.
Final sensing distance, spatial resolution, temperature accuracy and response time depend on the selected configuration, sensing cable, installation and project requirements.
