Title: Improvements in or relating to electric signalling systems
IPC: G08B25/04
Filed: 1932-03-23
Abstract: 398,877. Fire-alarm systems. STANDARD TELEPHONES & CABLES, Ltd. and BATES, E.. F., Connaught House, Aldwych, London. March 23, 1932, No. 8611. [Class 40 (i).] Relates to arrangements in a fire &c. alarm system for transmitting signals from a shortcircuited substation. In the drawing, Fig. 2 shows an ordinary substation with loop and earth impulse springs whilst Fig. 3 shows a substation similar to that shown in Specification 290,743 in which means are provided for transmitting signals in sequence without interference when a number of substations call simultaneously. Under normal conditions, relay A and register R at the central station are energized over the loop and signals transmitted from any substation are recorded on the register. If a break occurs in the loop the prolonged de-energization of the register causes contacts RC to close, energizing a solenoid winding OS which operates contacts K1, K2, K3, so that one pole of the battery is connected to earth and the other to the two legs of the loop in parallel. If the substation of Fig. 2 calls, signals are transmitted from earth M1 to register R over the non-broken side of the loop. If the substation of Fig. 3 calls,. contacts M3 or M4 are closed according to the position of the break as described in Specification 290,743, [Class 40 (i), Electric signalling systems &c.], and signals are transmitted from earth M2 by the springs SC2. If the substation of Fig. 2 is short-circuited when it calls, the operation of relay E over contacts M1 operates B, and when the earthed impulse springs open, the release of E whilst A remains energized operates C. The solenoid OS is thus energized to set up earth signalling conditions similar to those used with a broken loop. If a shortcircuit exists across the substation of Fig. 3 when a call is made, the closure of springs M3 completes a circuit M2, M3, F, SC2, K2 for relay E which operates B and on the opening of springs M3, relay C operates to switch over contacts K1, K2, K3 as before. On the next closure of M3, relay F operates to hold M3 closed and signals are transmitted by SC2 to register R over both sides of the line in parallel.
