Crowcon Gasmaster Gas Detector Control Panel

SKU
CrowconGasmaster

The Crowcon Gasmaster Gas Detector Control Panel has a modular design, so you can customise your control panel with all the input modules you need for your setting- and none of the ones you don’t, making it an adaptable, cost-effective solution.

    Gasmaster is a compact, versatile and powerful gas detection control panel that combines simple operation with an extensive array of input and output functions.


      Gasmaster provides all the information you need about your gas and fire detectors at a glance. The large multi-lingual display shows gas levels from all detectors simultaneously, with an intuitive and user-friendly menu system, making system adjustment and testing using buttons on the front panel a straightforward process requiring minimal training.

        The Gasmaster gas detector control panel can operate ‘stand-alone’, or interface with any alarm devices and control systems using a selection of outputs. With the ability to add up to four detectors in virtually any combination, the Gasmaster provides two levels of independent alarm per channel, with remote inhibit and reset capabilities meaning you have full control from anywhere on your site, at all times.


          Large Display:

          • ▪ All gas levels are displayed simultaneously for full systems status check at a glance
            • ▪ Alarm messages can be customised to indicate the name or location of any detector in alarm
              • ▪ The LCD can be set to display in many languages, for global usage
                • User Friendly:

                  • ▪ Intuitive menu system enables configuration changes to be made easily
                    • ▪ Event log feature allows system fault and alarm history to be viewed
                      • ▪ All functions, from day-to-day operation to re-calibration, can be carried out from the front panel making routine testing quick and easy

                        • Adaptable:

                          • ▪ Input and output features provide analogue, relay and Modbus outputs to suit your site’s communication needs
                            • ▪ Can monitor up to four detectors in virtually any combination of gas detectors, fire zones or Environmental Sampling Units
                              • ▪ Compatible with a 4-20mA or mV pellistor-type gas detector, providing ways to reduce system purchase and maintenance costs

                                • Modular and Versatile Design:

                                  • ▪ You only need to purchase the required number of input modules, as 1, 2 and 3-channel systems can be extended later by adding additional modules
                                    • ▪ Software enables re-configuration and event log upload in an instant
                                      • ▪ Two levels of independent alarm per channel
                                        • ▪ Remote inhibit and re-set facilities give you control from any point on your site
