DCFirst Claim
1. A first device for electrically connecting and detachably attaching to a second device identical to the first device, the first device having first and second ends and comprising:
- a first electromechanical connector at the first end;
a second electromechanical connector at the second end of the first device, the second electromechanical connector being physically structured to be electrically connectable and detachably mechanically couplable to a first electromechanical connector of the second device; and
an annunciator adapted to perform a module-specific task coupled to be electrically Direct Current (DC) powered from the first electromechanical connector of the first device and coupled to be activated in response to a signal received from one of the electromechanical connectors of the first device,wherein at least part of the DC power received from the first electromechanical connector of the first device is passed to the second electromechanical connector of the first device, and wherein the first device is configured to pass bi-directional digital data between the electromechanical connectors of the first device,whereby, when the first device is mechanically connected to the second device, DC power and bi-directional digital data are passed by the respective electromechanical connectors between the connected devices.

Abstract
Method, modules and a system formed by connecting the modules for controlling payloads are disclosed. An activation signal is propagated in the system from a module to the modules connected to it. Upon receiving an activation signal, the module (after a pre-set or random delay) activates a payload associated with it, and transmits the activation signal (after another pre-set or random delay) to one or more modules connected to it. The system is initiated by a master module including a user activated switch producing the activation signal. The activation signal can be propagated in the system in one direction from the master to the last module, or carried bi-directionally allowing two way propagation, using a module which revert the direction of the activation signal propagation direction. A module may be individually powered by an internal power source such as a battery, or connected to external power source such as AC power. The system may use remote powering wherein few or all of the modules are powered from the same power source connected to the system in a single point. The power may be carried over dedicated wires or concurrently with the conductors carrying the activation signal. The payload may be a visual or an audible signaling device, and can be integrated within a module or external to it. The payload may be powered by a module or using a dedicated power source, and can involve randomness associated with its activation such as the delay, payload control or payload activation.
