HOOD ASSEMBLY, METHOD FOR ASSEMBLING HOOD ASSEMBLY AND FIRESUPPRESSION SYSTEM COMPRISING HOOD ASSEMBLY
A hood assembly is disclosed. The hood assembly includes a housing having first and second walls arranged opposite to each other, the first and second walls being vertically oriented with respect to a floor on which the hood assembly is placed. The hood assembly includes a mechanical fire detection line configured to detect presence of a fire within the housing. The mechanical fire detection line is disposed between the first and second walls, and extending beyond the second wall. The hood assembly further includes a restricting element disposed on the second wall, such that the mechanical fire detection line extends beyond the second wall of the hood assembly by passing through the restricting element. The restricting element is adapted to allow movement of the mechanical fire detection line along a first direction, and restrict movement of the mechanical fire detection line along a second direction opposite to the first direction.

4 . The hood assembly of claim 3 , wherein the restricting element comprises a through hole, wherein the restricting element is disposed on the second wall such that the through hole of the restricting element is coaxial with the through hole on the second wall, and wherein the mechanical fire detection line further passes through the through hole on the restricting element.
5 . The hood assembly of claim 1 , wherein the second wall comprises a recess, and wherein the second wall comprises a through hole at the recess.
6 . The hood assembly of claim 1 , wherein the restricting element is disposed on the second wall at the recess.
7 . The hood assembly of claim 1 , wherein the mechanical fire detection line further comprises an output, wherein the mechanical fire detection line terminates at the output after it extends beyond the second wall of the hood assembly.
8 . The hood assembly of claim 1 , wherein the restricting element comprises a locking mechanism, wherein the actuating the locking mechanism causes the restricting element to restrict movement of the mechanical fire detection line along the second direction.
9 . A method for assembling a hood assembly, the method comprising:
providing a housing having first and second walls arranged opposite to each other, the first and second walls being vertically oriented with respect to a floor on which the hood assembly is placed;
