Abstract
In an emergency alarm system operating according to the chain synchronisation principle, the devices (El to En) are addressed automatically by their disposition on the line (MPL). Data are exchanged between the individual devices (El to En) and the central unit (Z) with the cyclic polling of a central unit (Z). At least one coupling device (T-coupler TK) is inserted in the primary alarm line (MPL) in any location between two devices. Further devices (E(n+l)) are connected to the coupler device (TK) via a spur line which forms an additional primary alarm line (MPLS). The coupler device (TK) has an electronic measuring and switching system (MSE) which controls a switching device, e.g. at least one line switch (LS1), which delays the polling of the spur line until all devices (El to En) of the primary alarm line (MPL) are polled, where the coupler device (TK) detects the polling of the last device (En) and then connects the spur line (MPLS) for further polling.
