International Gas Detectors TOC-750-NVR No-volt Release Assembly

International 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 IGD’s detectors and I/O modules.
