Electromagnetic lock drop ceiling for aisle containment system and method

1. An air containment system configured to span an aisle formed by two rows of racks or by one row of racks and a wall to form a ceiling, the air containment system comprising:

a frame structure configured to be supported by the two rows of racks or by the one row of racks and the wall, the frame structure including a first elongate frame assembly extending along a length of a first row of the two rows of racks, a second elongate frame assembly extending along a length of a second row of the two rows of racks or the wall, and a first elongate support member hingedly connected to the first elongate frame assembly;

at least one ceiling panel releasably supported by the frame structure; and

a lock assembly coupled to the frame structure and configured to release the at least one ceiling panel upon detecting a predetermined condition.

2. The air containment system of claim 1 , wherein the lock assembly includes an electro-magnetic lock coupled to the first elongate support member and the first elongate frame assembly.

3. The air containment system of claim 2 , wherein the electro-magnetic lock includes a first portion secured to the first elongate support member and a second portion secured to the first elongate frame assembly.

4. The air containment system of claim 3 , wherein the first portion includes a base metal material that is attracted to a magnet and the second portion includes a magnet that is capable of being selectively energized to attract to the first portion.

5. The air containment system of claim 2 , further comprising a control module to control the operation of the electro-magnetic lock.

6. The air containment system of claim 5 , wherein the control module is configured to move the electro-magnetic lock between a magnetized condition in which the electro-magnetic lock retains the first elongate support member in close proximity to the first elongate frame assembly and a de-magnetized condition in which the electro-magnetic lock disengages the first elongate support member to allow the first elongate support member to hingedly swing away from the first elongate frame assembly.

7. The air containment system of claim 5 , further comprising an alarm coupled to the control module and configured to activate prior to when the electro-magnetic lock disengages the first elongate support member.

8. The air containment system of claim 1 , wherein the lock assembly includes a mechanical fastener coupled to the first elongate support member and the first elongate frame assembly.

9. The air containment system of claim 8 , wherein the mechanical fastener is configured to move between a locked condition in which the mechanical fastener retains the first elongate support member in close proximity to the first elongate frame assembly and an unlocked condition in which the mechanical fastener disengages the first elongate support member to allow the first elongate support member to hingedly swing away from the first elongate frame assembly.

10. The air containment system of claim 9 , wherein the mechanical fastener includes a retaining element secured to one of the first elongate frame assembly and the first elongate support member and a locking element secured to the other of the first elongate frame assembly and the first elongate support member.

11. The air containment system of claim 1 , wherein the frame structure further includes a second elongate support member hingedly connected to the second elongate frame assembly.

12. A method of releasing one or more ceiling panels upon detecting a predetermined condition, the method comprising:

providing an air containment system configured to span an aisle formed by two rows of racks or by one row of equipment racks and a wall to form a ceiling, the air containment system comprising a frame structure configured to be supported by the two rows of racks or by the one row of equipment racks and the wall, at least one ceiling panel releasably supported by the frame structure, and a lock assembly coupled to the frame structure and configured to release the at least one ceiling panel upon detecting a predetermined condition, the frame structure including a first elongate frame assembly extending along a length of a first row of the racks, a second elongate frame assembly extending along a length of a second row of the racks or a wall, and a first elongate support member hingedly connected to the first elongate frame assembly;

detecting a predetermined condition; and

releasing the at least one ceiling panel,

wherein releasing the at least one ceiling panel includes hingedly moving the first elongate support member with respect to the first elongate frame assembly by the lock assembly.

13. The method of claim 12 , wherein the predetermined condition is a temperature within the aisle greater than a set temperature or smoke detected within the aisle.

14. The method of claim 12 , wherein the lock assembly includes an electro-magnetic lock secured to the first elongate support member and the first elongate frame assembly.

15. The method of claim 14 , wherein releasing the at least one ceiling panel includes controlling the movement of the electro-magnetic lock between a magnetized condition in which the electro-magnetic lock retains the first elongate support member in close proximity to the first elongate frame assembly and a de-magnetized condition in which the electro-magnetic lock assembly disengages the first elongate support member to allow the first elongate support member to hingedly swing away from the first elongate frame assembly.

16. The method of claim 12 , further comprising, prior to releasing the at least one ceiling panel, operating an alarm to warn individuals within the aisle.

17. The method of claim 16 , wherein the alarm includes a visual alarm and/or a sound alarm.
