System 57 Controller

System 57 Controller


For almost half a century, our gas detection systems have provided the safety needed to protect plant and personnel from flammable and toxic gas hazards. Across the globe, they are installed in a wide variety of applications ranging from simple small-scale systems to some of the World’s largest fully integrated fire and gas detection systems.

To fulfill the unique requirements of each individual application requires a control system with unlimited flexibility.  The modular design approach employed by the System 57 enables you to define, in detail, the unique control and alarm parameters to fulfill your requirement.

System 57 accepts inputs from flammable and toxic gas detectors, a large range of flame, smoke and heat detectors and manual call points. Available outputs include relays, analogue signals and industry standard digital protocols. Packaged in either wall mounting cabinets or panel mounting racks, System 57 can be used stand alone or integrated into the heart of a fire and gas system.

Whatever the application, large or small, our sales engineers and customer service representatives are available to discuss your requirements and recommend the control system that’s best for you. 

Control Cards
The System 57 offers unrivalled flexibility with both fire and gas control cards available in the same rack.

Gas Control Cards
The System 57 gas control cards provide display and alarm facilities for the full range of our gas detectors. Their concise, back lit, multi-part LCD displays the gas reading and status in both analogue bar graph and digital numeric forms. In addition, there is an alphanumeric message section to give sensor (and engineering function) status. There is a choice of either the single channel 5701 or the four channel 5704 gas control cards. Each card has two input options; one is for catalytic bridge type while the other is for 4-20mA sensors or transmitters.

•  3 levels of alarm
