Abstract: A safety system for a stable comprises "smart detectors" installed in the stable for detecting at least one abnormal condition in the stable, a siren and/or flashing strobe installed in each stall for spooking horses out of their stalls, an electro-magnetic lock provided on each said door, a power source supplying power to each said electro-magnetic lock keeping each door closed in the absence of the abnormal condition, and a controlling means continually monitoring said "smart detectors". Once the abnormal condition has been detected, the controlling unit immediately turns down the power supplied to each electro-magnetic lock and, with a certain delay, actuates the siren and/or flashing strobe.
