Title: Improvements relating to alarm systems
Inventor: CHURCH WILLIAM DAVID
IPC: G08B27/00
Filed: 1986-05-14
Abstract: An alarm system comprises a sequence of individual units 12 interconnected in a chain by means of cables 11. Alarm devices may be connected to cables 5 and 8. Each unit is operative to transmit interrogation signals to an adjacent unit in the chain to check the status of that unit. Each unit contains circuitry responsive to signals received through one of the cables 5, 8 to pass an alarm message to the adjacent interrogating unit. The circuitry is also operative to create an alarm signal when an interrogated adjacent unit fails to send back a predetermined receipt signal or when an interrogated adjacent unit transmits an alarm message. Thus a series of individual properties can be protected by the overall system such that an alarm condition occurring in one of the properties will produce a warning on a unit 12 in one of the other properties. <IMAGE>

Abstract: The board game includes a triangular board (2) having a triangular playing area (6) divided into sixty-four equal-sided triangles (4). Two sets of triangular playing pieces are provided. Each piece (8, 10) has a different coloured band along each side. Each set includes CIRE pieces (8) which can move one triangle to another by pivoting about an apex and CENTIRE pieces which can move from triangle to adjacent triangle and be orientated during the move in any direction desired by the player. Each player brings his pieces into challenging positions with another player's pieces by causing sides to abut. The winner of the challenge is the piece whose abutting colour band is higher in a predetermined order of precedence. The exception to the rules is where a CENTIRE challenges a CIRE in which case the CENTIRE only wins the challenge when the colours of the two abutting bands are the same. <IMAGE>
