AGC Master and AGC Slave Extinguishing Apparatuses
Installation of Extinguishing Apparatuses
AGC Master and Slave Extinguishing Apparatuses are designed to be installed on the top shelf of the cabinet (fig.4). The devices have to be installed horizontally. Free space under the panel must be exact of 2U 1U=1¾”=44.45mm). When the AGC Master Extinguishing Apparatus is situated on the left side, AGC Slave Extinguishing Panels must be installed on the right side

The connection between the devices is arranged by a set of patch cords installed in Slave device.
NOTICE! Requirements for the secured cabinets
- Extinguishing Apparatus AGC Master and AGC Slave can only be applied in server cabinets (or other cabinets compatible with this type of device) whose air-tightness enables a required concentration of HFC 236fa (FE-36) extinguishing agent to maintain after the release of gas. The cabinets must be air-tight from the sides (no perforation, gaps, holes etc.). Cabinets may have ventilators but they need to be extra-air-tightened with nonwoven fabric (offered by manufacturers producing devices of this kind). It is also advised to fit a cabinet with a actuator operated damper in order to increase air-tightness of the cabinet during fire extinguishing. The bottom of the cabinet should be wadded or its air-tightness should be increased by the application of an actuator operated damper.
- It is crucial to remember that cabinet’s door and other parts of the case (side doors and other moving objects) must be hermetically closed. Only air-tight zone guarantees the required concentration of HFC 236fa (FE-36) gas in the case of the fire.
