Act like you are man and this is your fucking planet and you know it. Assuming it wasn't weary of you, which it is likely to be, you Get big, stick out your chest, put some bass in your voice and let out your most primal caveman shout. Swing your jacket around. Stomp your feet. Get it in your head that this is probably happen and you're going to have to kill a motherfucker. I carry a flashing LED light that's brighter than fuck to blind and disorient anything running at me, but most predators try to flank or come in from behind. Your rape alarm though will definitely help, to answer your question, but in all likelihood, once the animal's decided to make you prey, he's decided to make you prey. And he's hungry and your alarm may not scare him.
Arm yourself.
