The ANWETECH AT-F325 Manual Release Key Switch is designed for manual release control in fire suppression and extinguishing systems. It is intended for panel mounting and provides a normally closed contact for integration into release logic or supervised control circuits. With its red 40 mm operator head, the device offers high visibility and clear identification during emergency operation.
The switch uses a key-turn reset mechanism, allowing controlled operation and secure reset after use or testing. Its compact structure and standard M22 mounting thread make it suitable for installation on enclosure doors, control panel faceplates and fire suppression release stations.
AT-F325 is ideal for use in gas extinguishing systems, suppression control panels and other fire protection applications where a manual release function is required. It should always be installed and commissioned according to the approved project design and system logic.
