IPC: G08B29/12
Filed: 1958-06-24
Abstract: 866,168. Protective arrangements. ASTRAL SWITCHGEAR Ltd. June 16, 1959 [June 24, 1958], No. 20209/58. Class 38 (5). In an alarm or indicator system having a number of separate alarm circuits fed from a common D.C. supply, a unidirectional device is located in each circuit such that reversal of polarity of the D.C. supply simulates the operation of control switches in all the circuits for test purposes. In each circuit the operation of a control switch S1, which may respond to a fault condition in associated apparatus, causes the energizing of a relay A/3 which momentarily closes contacts A-a to energize a common bell relay B/2. The bell relay closes contacts B-a, which with the now closed contacts A-b of the relay A/3, complete the circuit for a common alarm bell B. The closing of contacts A-b also cause the operation of a " flashing " relay C/2 so that the lamps l1 are flashed over contacts A-c. To test the circuits, the operation of a changeover switch S3 reverses the polarity of the supply from a D.C. source P. A rectifier R associated with each switch S1 is now able to conduct so simultating the operation of the switches and causing the operation of all the relays. Should the circuits be arranged for control by normally closed switches, the rectifiers are connected in series with the switches so that when the polarity is reversed, the rectifiers cease to conduct and simulate the opening of the switches.
