Abstract

A protection device for a spa pack has a sensor and associated controller responsive to failure of the electrical circuits in the spa pack and a warning device responsive to operation of the controller to provide a warning of failure of the power supply for the spa pack. An automatic dialling system responsive to the controller provides automatic placement of a warning signal on a telephone line connected alarm system. The controller is connected within a circuit protected by a ground fault interrupter.

Claims

1. A protection device for an operational spa pack of a spa, the spa pack having a power supply and an electrical state, the device comprising:

a sensor responsive to the electrical state of the spa pack;

a controller responsive to the sensor;

a ground fault circuit interrupter connected between the power supply and the spa pack; and

a warning device responsive to the controller to provide a warning upon operational failure of the spa pack.

2. The protection device of claim 1 in which the ground fault circuit interrupter is connected between the controller and the spa pack.

3. The protection device of claim 2 further including:

an automatic dialling system responsive to the controller to provide automatic placement of a warning signal on a telephone line connected alarm system upon operational failure of the spa pack.
