A method and device for protecting and installing a fire protection sprinkler. The method includes torquing the sprinkler with a protective device strapped about the sprinkler and pulling a releasing segment of the device to expose operational components of the installed sprinkler. The protective device includes a first and second member having a hinged connection about which the members pivot with respect to one another between an open configuration and a closed configuration. At least one of the members includes a torque assist portion for applying the torque to the sprinkler and a releasing segment spaced laterally from the hinge connection to pivot the members from the closed configuration to the open configuration and release the protective device from the sprinkler.

A method and device for protecting and installing a fire protection sprinkler assembly having a thermally responsive trigger. The method includes shielding and torqueing a fire protection sprinkler with a protective device having a torque assist portion. The protective device includes a first and second member strapped about the sprinkler assembly. Each of the members of the protective device has a first lateral end and a second lateral end disposed about the thermally responsive trigger. At least one of members has a concave segment and a convex segment formed between the first lateral end and the second lateral end. The convex and concave segments define therebetween an external torque assist surface of the protective device that can be used to manually torque and install the sprinkler assembly.

A device for protecting and installing a fire protection sprinkler. The protective device is embodied as a tubular cap that axially receives the sprinkler. The protection and installation device includes a wall with a stiffening element to facilitate the strength and rigidity of the device so that it can sufficiently transfer a torque to install the protected sprinkler.

A device and method of protecting and installing a fire protection sprinkler. The device includes a tubular cap that axially receives the sprinkler. The device also includes torque assist features including an external rotational drive feature and an internal rotational drive feature.

A fire suppression system comprising a polymer housing and an internal channel arranged to communicate a fluid from a fluid inlet to a fluid outlet. The fluid outlet is in the form of at least one aperture extending through a portion of the polymer housing into said channel.

A sprinkler accelerator system includes an accelerator and at least one orifice. The accelerator is coupled with at least one pipe coupled with at least one sprinkler, and vents gas from the at least one pipe when the at least one sprinkler opens. The at least one orifice controls a rate of change of pressure in the at least one pipe to control operation of a flow control valve coupled with the accelerator.

The sprinkler head with integrated shut-off valve is configured for use in a fire sprinkler system and a water source. The heat generated by a fire automatically actuates the sprinkler head with integrated shut-off valve. The sprinkler head with integrated shut-off valve further comprises a manually operated valve. The manually operated valve closes the sprinkler head with integrated shut-off valve in cases inappropriate actuation. The sprinkler head with integrated shut-off valve comprises a deflector, a heat sensitive release mechanism, a wedge seal, a valve block, and a threaded connection. The threaded connection attaches the sprinkler head with integrated shut-off valve to the water source. The heat sensitive release mechanism and the wedge seal actuate the valve. The deflector directs the water released by the sprinkler head with integrated shut-off valve. The valve block forms the manually operated valve of the sprinkler head with integrated shut-off valve.
