Retrofit Self-Annunciating Sprinkler

A water-powered fire suppression and alarm system in the form of a retrofit kit for installing in proximity to a cooking appliance in a residential dwelling and connecting to an existing water source already installed in the dwelling, comprising:

• (a) at least one sprinkler head;
• (b) a water-powered alarm;
• (c) a fire resistant transfer line assembly including a fire-resistant transfer line communicating with the water-powered alarm and connected to a multi-port coupling by way of a first port, the multi-port coupling also including a second port configured to connect to an existing residential water source, said fire resistant transfer line assembly further providing flow from the existing residential water source to the sprinkler head;
• and
• (d) a housing assembly having a housing with a vertical span of about 3 inches to about 12 inches, having one or more conduits mounted therein, wherein the sprinkler head and the water-powered alarm are mounted to the housing assembly and the fire resistant transfer line assembly is connected to the housing assembly such that it communicates with the sprinkler head independently of the water powered alarm;
• whereby when the second port is connected to the water source, thereby providing water pressure, and the sprinkler head is activated to allow flow therethrough, water flows through the transfer line thereby necessarily activating the alarm.
