SPARK-EX Control Unit DC1

The SPARK-EX Control Unit DC1 is engineered for installation in environments where explosive concentrations of dust may be present.

Each DC1 unit can connect to and manage up to four spark detectors and two automatic extinguishing modules. The controller is capable of monitoring a single, comprehensive installation or two independent process lines simultaneously.

Furthermore, the unit is equipped with a two-step automation protocol. Step 1 activates upon the detection of system irregularities, while Step 2 initiates a user-defined response sequence based on pre-configured parameters.

Key Features of the DC1 Control Unit:

Decentralised monitoring
Easy alarm reset functionality

Controls up to two automatic extinguishers for immediate response to ignition sources.
Monitors heat trace cables, water flow, pressure, and valves to maintain operational safety.
Integrates with existing safety systems via CANbus
Suitable for ATEX Zone 21 areas.
The DC1 Control Unit delivers precise, reliable safety management, supporting stringent fire risk mitigation for industrial applications.

Testing and Reliability

Performs automatic self-tests every two minutes to verify system readiness.
Manual test option available for on-demand diagnostics.
Visual and audible indicators ensure prompt status and fault notification.

Two-Step Alarm System

Step 1: Detects sparks and triggers extinguishing, accompanied by alarms and flashing lights.
Step 2: Configurable to stop ventilation, filtration, and production equipment if hazards persist, with programmable logic to meet specific site needs.

Alarm and System Status Indication:

Alarm Activation

Upon detecting a spark, ember, or fire, the SPARK-EX system triggers a high-intensity flashing light and a horn up to 98 dB. This ensures immediate awareness in loud industrial settings, with the visual signal serving as an added safeguard for staff in environments where hearing protection is used.

Fault Indication

If a system fault occurs, such as a sensor or communication error, only the flashing light activates. The horn remains silent, providing maintenance personnel with a clear signal to investigate without disrupting operations or causing confusion with fire alarms.

These clear, differentiated signals help maintain optimal safety and operational readiness.

Control Panel (Optional)

The Control Panel provides centralised Human-Machine Interface (HMI) with a touch screen offers a comprehensive overview of the entire system, simplifying monitoring, configuration, and event logging for up to 34 independent systems.
