Abstract

The water cistern alarm consists of two boxes connected via an electrical circuit which together are used to monitor the amount of water allowed in the cistern by its ballcock. A lightweight plastics ball (6) rises with the level of the water in the cistern, causing its supporting arm to rotate and contact the striking plate (5), to complete a circuit and sound an alarm. <IMAGE>

Description

WATER CISTERN ALARM.
This invention concerns a Water Cistern Alarm.
The invention is designed to warn of any fault in the operation of the Ballcock or it's associated parts by which water may enter the cistern.
The specifications of the invention are as detailed below: FIG 1. Shows the internal wiring of the two units.
N.B. The lids have been omitted to illustrate internal details.
FIG 2. Shows a schematic drawing of the wiring.
Refering to Fig 1.
The invention consists of two boxes, Unit A which is a wall mounted unit. The unit houses a Battery (1) and a Speaker (2). It is supplied with an ON/OFF Switch (3) to arm the unit and a Test Button (4) to check the unit is functioning.
The second box, Unit B is a cistern mounted unit which consists of a lightweight Plastic Ball (6) on the end of a flexible wire tube which in turn is connected, through a pivot point, to an arm which is free to rotate with the level of the water rise. If the level rises above a pre-determined point, the arm will contact the striking Plate (5) and complete a circuit which will sound the alarm. (95db).

Claims (3)

CLAIMS.
1. A Water Cistern Alarm consisting of two boxes, one of which is a cistern mounted unit comprising of a means to monitor and adjust to the level of water in the cistern, and by means of an electrical circuit warn of any rise in the level.
The second box to be a wall mounted unit secured in an easily accessable place adjacent to the cistern, through which the alarm will sound.
2. A Water Cistern Alarm as in Claim l, which will detect any fault in the operation of the ballcock, by which water will continue to enter the cistern after use.
3. A Water Cistern Alarm as in Claim l and Claim 2, which will detect any rise in the water level in the cistern due to faults developing in the fittings or connections of the ballcock or associated parts within the cistern.
