When accompanied with door alarms, exit alarms can be handy for a number of different things. There is a wide variety of alarms to choose from, and the design of the alarm can actually save your life as well. The most notable reason to get an exit alarm is to prevent intruders, but having an alarm above the door can save you during a fire as well. How many alarms you need around your house or office is solely up to you. It is recommended that you purchase at least one for your front and back doors. But you have to consider the fact that many burglars are well aware of alarms in the front and back. Because of this, side doors, basement doors and garage doors are all fair game as well. If you settle for the first alarm you see, you may end up paying far more than you need to. Take the time to research for the sake of your safety, your family’s safety, and financial reasons as well. If you are at your home you can turn any door into an emergency exit, what I mean by that is that you can leave a door unlocked and with your emergency exit door alarm, it will go off when someone is entering the door that shouldn't be. This is great during the day when you are home alone and like to keep a screen door open or the front door open to let in a little light, or to cool down the house in the summertime. If you own a business then the same situation applies to you as well. You need to leave doors unlocked during business hours so you put a emergency exit door alarm on all of your doors but the main one and an alarm goes off if someone enters or exits from these doors.Also in the case of an emergency these doors will be unlocked and people will be able to get out of the emergency exit doors if they need to. You can also get emergency exit door signs that say alarm will sound. I'm sure you have seen these. Whether you want to protect your home or your business emergency exit door alarms are a good idea to not only warn you of danger so you can escape or call for help, but to protect your home or business as well.
