Codesec GS290K Gas Detector with Relay

The Codesec GS290K is engineered to provide a first line of defense against gas-related explosions. It utilizes a high-quality catalytic bead or semiconductor sensor that is calibrated to trigger an alarm at a fraction of the Lower Explosive Limit (LEL), typically around 10%. The standout feature of the “K” variant is its integrated relay. This allows the detector to function as a standalone safety device or as part of a larger fire alarm system. When gas is detected, the relay changes state, which can be wired to a solenoid valve to automatically cut off the gas supply, preventing a disaster before a spark occurs.

Key Features
? Dual Alert System: Equipped with a powerful internal buzzer for audible warning and a clear LED indicator for visual status (Power, Fault, Alarm).
? Integrated Relay Output: Provides a dry-contact relay that can be used to shut down gas flow via a solenoid valve or interface with a central fire alarm panel.
? High-Stability Sensor: Uses a catalytic combustion sensor that provides high accuracy and long-term stability against environmental changes.
? Self-Test Function: Features a test button to verify the functionality of the sensor, internal alarm, and relay output.
? Auto-Reset: Once the gas concentration drops below the alarm threshold, the device automatically resets to its normal monitoring state.
