Abstract
A sprinkler head includes a sprinkler body and a frangible sprinkler bulb connected to the sprinkler body. The frangible sprinkler bulb includes a resistive track embedded in a cylindrical wall. A microchip and a diode are operationally connected in series to the resistive track. The microchip and the diode are connected in parallel to each other. In a tracking mode, a first current flows from a first terminal to a second terminal sequentially through the resistive track and the microchip. In a releasing mode, a second current flows from the second terminal to the first terminal sequentially through the diode and the resistive track.

A sprinkler head comprising:
- a sprinkler body;
- and
- a frangible sprinkler bulb connected to the sprinkler body, the frangible sprinkler bulb comprising:
- a cylindrical wall;
- a resistive track embedded in the cylindrical wall;
- and
- at least one microchip and at least one diode operationally connected in series to the resistive track, the at least one microchip and the at least one diode connected in parallel to each other,
- wherein, in a tracking mode, a first current flows from a first terminal to a second terminal sequentially through the resistive track and the at least one microchip,
- and wherein, in a releasing mode, a second current flows from the second terminal to the first terminal sequentially through the at least one diode and the resistive track.
A fire detection system comprising:
- a sprinkler head comprising:
- a sprinkler body;
- and
- a frangible sprinkler bulb connected to the sprinkler body, the frangible sprinkler bulb comprising:
- a cylindrical wall;
- a resistive track embedded in the cylindrical wall;
- and
- at least one microchip and at least one diode operationally connected in series to the resistive track, the at least one microchip and the at least one diode connected in parallel to each other;
