Fire Detection in Utility Tunnels

Sensa's Dual Integrity systems provide reliable, intelligent fire detection for essential utility services carried within network utility tunnels. Uniquely offered by Sensa are long range, high speed detection solutions.

The system provides cost-effective fire detection and ambient temperature monitoring for tunnels carrying critical services including telecommunications and power distribution cables.

Fiber optic cable is immune to electro-magnetic interference (EMI) and signal quality is therefore not affected by the power and signal cables.

Sensa’s systems are connected via an Ethernet backbone to a central control room environment where operators are able to view an on-screen map of the alarm and temperature data.

The Sensa system’s ability to identify the precise location and temperature of a fire ensure that the fire can be tackled efficiently given the remote, unmanned nature of utility tunnels.

The system is cost-effective to install and having no active components is low maintenance, which is reflected in its low through life costs.

Key benefits

• Fast reliable fire detection
• Maintenance-free robust sensor cable ensuring low through-life costs
• Sensor not affected by Electro Magnetic Interference (EMI)
• Intelligent system capability ensure the unique ability to automatically detect recover from and trigger an alarm warning of breakage or degradation of the sensing fiber.
• Ease of installation
