Burglar Alarm

Occasionally, a house has a built-in burglar alarm that generates a loud siren noise when a player/zombie enters a house via the door or window. The burglar alarm sounds for about two in-game hours and the sound distance has a radius of about 250 tiles, which is the same distance that sound from a Sawed-off JS-2000 Shotgun will travel. Since zombies are attracted to sound, the beeping of the burglar alarm will attract even more zombies to the alarm's location. A good way to spot a burglar alarm before it even rings is to watch nearby zombies after you get inside the house. If there's no noise, yet suddenly the zombies in the area start to wander towards the house, a burglar alarm is about to sound, thus giving the player enough time to escape.
