Re: Audible Alarm for shorts

Here is another option for shutting down. Wire your track through a Digitrax PM42 or a similar device. You would be able to wire up to 4 tracks or 4 blocks with it. If you still want a buzzer, wire a low voltage, low wattage relay across the rails and use it's NC contacts to switch on a buzzer when the track power is opened by the auto auto-circuit breaker.
There are a number of auto circuit breakers available that may better fit your needs.
The brake light bulbs are very useful if they are visible. They even encourage a crescendo of Short, SHORT, short, from the viewers but they are ineffective if they are hidden.
Where is this popular restaurant. Just for the trains mind you, just the trains.

Our club is using NCE CP6 for circuit protection (tail light bulbs), because of the large number of visitors (we are in a popular restaurant) and the fact that half the layout is in a separate room we would like to add a buzzer system to alert us when there is a short. Because of the crowds and a lift up bridge it takes a while to reach the command station. We are installing emergency shut offs so the power can be cut quickly but if we don't know there is a short it maybe too late. We did have an incident where the light was on long enough that the smell of smoke was our first clue (the CP6 was not in your line of sight).
