International Gas Detectors TOC-750-NVR No-volt Release Assembly
International GasDetectors TOC-750-NVR No-volt Release AssemblyInternational Gas Detectors addressable no-volt release assemblies provide enhanced safety for alarm process control. In many systems it is typical that the gas detection systems shuts off gas supplies in the event of a gas alarm. On clearing an alarm it may not be desirable for the detection system to directly re-enable the gas supply.The No-Volt release unit requires manual intervention to re-initiate the gas supply. The module is also provided with an emergency push button which can be either configured for local operation or feedback to the system controller.The module is addressable and can be placed on the same cable run as IGDs detectors and IO modules.
