# CTS Single Channel Fuel Tank Alarm

The CTS Single Channel Fuel Tank Alarm provides reliable, focused monitoring for a single alert condition, offering a practical alternative to multi zone systems when only one risk needs to be managed. Designed for use on fuel and fluid storage tanks, it delivers clear visual and audible warnings to help protect sites from overfills, low level issues or bund leaks.

## Flexible Single Zone Monitoring

This CTS Single Channel Fuel Tank Alarm allows the user to configure the unit to detect either a high level, low level or bund leak depending on site requirements. This flexibility makes it suitable for a wide range of installations where only one alarm condition needs to be monitored, avoiding the cost and complexity of larger multi zone systems.

## Clear Visual and Audible Alerts

A seven segment red LED display clearly indicates the active tank status, ensuring alarm conditions are easy to identify. The integrated 90dB sounder provides a strong audible warning, while a test button allows users to confirm correct operation and view the current alarm configuration. A mute function is also included to silence the sounder when required.

## Designed for Site Integration

This mains powered version includes a volt free relay, enabling connection to external systems such as a building management system or a secondary alarm unit in another location. This allows alarm conditions to be monitored remotely, for example from an office or control room, improving overall site oversight.

## Suitable for Multiple Fluids

Although widely used as a diesel tank alarm, this unit is also suitable for monitoring tanks containing water, waste oil and certain chemicals. Versions are available both with a diesel or oil probe and without a probe for use with alternative fluids, offering flexibility across different storage applications.

## Installation Considerations

The unit is housed in a weatherproof IP55 enclosure for dependable performance in demanding environments. All cables must be free of electrical noise to ensure accurate operation and prevent interference with alarm signals.
