Life safety mounting system and method
View Patent ↗A life safety assembly includes an attachment stud configured to attach to a surface, and a life safety device that is mountable on the attachment stud. The life safety device has a receptacle configured to receive and interlock with the attachment stud to mount the life safety device with respect to the surface.
1. A life safety assembly, comprising:
an attachment stud configured to attach to a wall or ceiling surface using a single screw, wherein the attachment stud comprises a center of the attachment stud, wherein the attachment stud comprises a hollow post located at the center of the attachment stud and configured to receive the single screw to attach the attachment stud to the surface; and
a life safety device including a receptacle configured to receive and interlock with the attachment stud and receive the hollow post projecting into an interior of the receptacle to mount the life safety device with respect to the surface;
wherein the attachment stud is rotatable about an axis defined by the single screw prior to a tightening of the single screw without changing a mounted position of the life safety device;
wherein the life safety device is rotatable to a plurality of positions to engage the attachment stud;
wherein the hollow post comprises a post projection with a mounting tab projecting from the side of the hollow post, the mounting tab configured to interlock with the receptacle.
2. The life safety assembly of claim 1 , further comprising a lockout mechanism that obstructs an opening of the receptacle when a battery is not installed in a battery compartment on the life safety device.
3. The life safety assembly of claim 1 , wherein the attachment stud has an alignment mark.
4. The life safety assembly of claim 1 , wherein the life safety device is non-circular in shape.
5. The life safety assembly of claim 1 , wherein the receptacle has a stop to indicate a position adequate to interlock the attachment stud with the receptacle has been obtained.
6. The life safety assembly of claim 1 , wherein the receptacle has a collar with a plurality detents, the detents and collar configured to interlock with the mounting tab.
7. The life safety assembly of claim 1 , wherein the attachment stud or the life safety device has a compressible material affixed to the life safety device or the attachment stud, the compressible material capable of creating an opposing force between the life safety device and the attachment stud when the life safety device and the attachment stud are interlocked.
8. The life safety assembly of claim 1 , wherein the attachment stud has a base plate with a base foam attached to the base plate, the base foam capable of compressing against the life safety device to provide a force that interlocks the attachment stud with the receptacle.
9. The life safety assembly of claim 1 , wherein the attachment stud has an attachment cleat, the attachment cleat configured to provide traction for the attachment stud on the wall or ceiling surface.
10. A method of mounting a life safety device, the method comprising:
mounting an attachment stud to a surface using a single screw, wherein the attachment stud comprises a center of the attachment stud, wherein the attachment stud comprises a hollow post located at the center of the attachment stud and configured to receive the single screw to attach the attachment stud to the surface;
mounting a life safety device onto the attachment stud so that the hollow post projects into an interior of a receptacle in the life safety device;
rotating the attachment stud about an axis defined by the single screw prior to a tightening of the single screw without changing a mounted position of the life safety device; and
rotating the life safety device about an axis defined by the stud to a position in which the stud and the receptacle are interlocked;
wherein the receptacle defines a plurality of circumferentially spaced locking positions;
wherein the attachment stud is provided with a mounting tab projecting from the side of the hollow post, the mounting tab configured to interlock with the receptacle.
11. The method of mounting of claim 10 , wherein the receptacle is provided having a collar with a plurality of detents, the detents and collar configured to interlock with the mounting tab.
12. The method of mounting of claim 10 , further comprising aligning the attachment stud to a surface substantially parallel to an alignment mark on the attachment stud.
13. The method of mounting of claim 10 , further comprising inserting batteries into a battery compartment of the life safety device such that a lockout mechanism does not obstruct the receptacle.
