ABSTRACT:
An alarm mechanism for use in chlorinators using chlorine tablets. The alarm mechanism signals when the chlorine tablets have dissolved to a pre-determined quantity and are in need of replenishment. The alarm mechanism has a low tablet register mechanism and an indicator. The low tablet register mechanism registers when the chlorine tablets dissolve to the pre-determined quantity, and preferably includes a counterweight mechanism calibrated and constructed so that it is activated when the chlorine tablets dissolve to the pre-determined quantity. The indicator indicates when the low tablet register mechanism registers that the chlorine tablets have dissolved to the pre-determined quantity. Preferably, the indicator includes a sensor and an alarm. The sensor senses when the register mechanism registers the dissolution of the chlorine tablets to the pre-determined quantity. The alarm, such as a horn or a light, signals the activation of the sensor. The sensor activates the alarm by direct transmission, in which electrical wiring provides electrical communication between the sensor and the alarm, or by remote transmission, in which an electronic transmitter and receiver provide communication between the sensor and the alarm.
