MerlinGuard Hydrogen System

The MerlinGuard is a 16 zone detection panel. Up to 16 detectors can be used in any combination and can be individually monitored on the MerlinGuard TFT display.

The MerlinGuard is a gas detection panel designed by American Gas Safety (AGS) to be used with AGSHTFT detectors. It is intended for use in spaces that require gas detection, this solution is specifically hydrogen detection and provides features such as fan control options, alarm damper control, and connectivity to Building Management Systems (BMS). The panel has four output options for pre-alarm and high-alarm conditions, and it also contains a 0-10V output that can be utilized by the BMS or for fan control via VFD. The MerlinGuard is a compact and versatile solution for gas detection for various applications, providing comprehensive features to meet the requirements and guidelines for hydrogen.

AGS Hydrogen Gas Detectors

The AGSHTFT is a hydrogen gas semiconductor detector and is typically used as a standalone unit or in conjunction with an AGS controller. Hydrogen is lighter than air and will therefore rise, meaning the gas sensor should be mounted 1ft from the ceiling of the protected area. At detection, the detectors will go into alarm at 10% LEL. When connected to an AGS controller, built-in alarm relay outputs can be used to activate the power supply to a remote audible alarm, activate ventilation fans or shutdown battery chargers. This can then be rectified by resolving the leak, allowing the sensor head to clear and resetting the attached AGS panel and detector.
