Title: Incorrect information prevention system of emergency announcing equipment
Inventor: TSUKAMOTO SHIGEO
IPC: G08B25/00
Filed: 1980-09-21
Abstract: PURPOSE:To prevent the announcement of incorrect informaion after a loop which may cause the incorrect information is formed, by detecting an abnormality by a circuit composed of relays. CONSTITUTION:When an information announcement switch K is turned on, a relay A operates, so a relay T operates to open a contact t1, so that the relay A is released, then the relay T is also released. Consequently, the relays A and T turn on and off continuously. A counter 5 detects the intermittence of the relay T and, when going up to a prescribed number, actuates a main announcing equipment body 9. If an abnormal loop (e.g., short circuit n2) puts the relay A in operation, on the other hand, the relay T operates similarly, and consequently the input terminal (m) of an incorrect-information detecting circuit 4 is earthed via a contact t2. Consequently, a normally conducting transistor TR1 turns off to operate a relay C, and consequently the counter 5 is cleared to prevent the action of the announcing equipment body 9.
