The GASMASTER is an electronic device that has been developed as a concentrator of medical gas alarm network. The GASMASTER can manage up to 30 devices connected by a twisted shielded cable using the MODBUS protocol. The configuration can be easily modified using the integrated touch monitor, each input of each device can be configured in all their parameters (names, LEDs, sound signals, modbus address, relays ...).
The GASMASTER has also been designed to be integrated into a BMS (Building Management System) system for monitoring its status and any alarms present. For this purpose, using the RJ45 socket and connecting an Ethernet cable, is possible to interrogate the GASMASTER using the MODBUS TCP/IP protocol.
The GASMASTER is also equipped with 2 relays which can be activated and configured, also for the purpose of reporting the status of the GAS MASTER to an appropriately configured remote station.
The GASMASTER is also equipped with a back-up battery able to support its functioning in case the main electric network ceases to supply current. The duration of this battery is limited to few hours.
The absence of current condition is however interpreted by the GASMASTER as an alarm condition, the sound system will then operate and will cease once the main current source has been restored.
