FM approved barriers

FM-qualified liquid barriers

These barriers were tested to withstand temperatures of 1000°C for more than 30 minutes. They are suitable for containment of combustible and non-combustible solids and liquids. These barriers close automatically without the help of external energy sources.

Features:

• Consists of a vertically standing barrier body with hinge and casing on one side and a U-profile on the other side.
• The barrier is held in the vertical rest position by an electromagnet.
• The barrier closes slowly upon activation by the liquid sensor, a signal from the fire alarm control unit, a power failure or manually with the control button.
• The downward movement is braked by means of a gas pressure spring.
• In the closed position, the barrier is automatically locked by a gas spring-operated impulse tensioner.
• Locking firmly presses the barrier body against the seals in the side guides and against the bottom, ensuring a hermetic seal.
• To open the barrier, it is first unlocked and then can be manually raised back up.
• Manufactured, tested and approved according to FM Class 4985.
• Approved by FM Approval and MPA construction method.
• Delivered and assembled ready for operation by TUV, WHG and FM-approved German manufacturer THOMAS
