The purpose of a home security system is to deter a would be burglar from entering your home. If the burglar does gain entry then a secondary defense that your home alarm system should be providing is to minimize the amount of time that the criminal spends in your home.

But my home is monitored by a Central Station

A home security system that is monitored is definitely a valuable addition but thieves know that they have a few minutes before any police will be on the way. With budget cuts there are just not enough police to go around. A call from a possible break in are going to be a lower priority than many other calls.

So the best defense is to make your home so uncomfortable to be in that the criminal will exit as quickly as possible.

Interior Sirens

There are over 2 million burglaries each year. You want to try and make sure that if a burglar does enter your home that he will not want to stay inside. You can achieve this by having a loud alarm. Many of the alarm companies today are installing all in one systems. These systems have the control panel and the siren all built into one panel. In the older style panels the brains of the system were located in an attic or a closet and the keypad was located in a convenient location elsewhere. The interior siren would be a separate component that would be located high up on a wall. Most alarm companies would also provide an outside bell. With the all in one systems the built-in sounder is all that is used.

Install a Secondary Interior Siren

The all in one systems do have a separate output that will provide power to additional sirens or bells. The problem is that installation companies today only want to install a basic system. They want to get and get out as quickly as possible. Your system is adequate but it could be a lot better. With the addition of an extra siren inside and a bell outside you are not only making it uncomfortable for the intruder to stay but with an outside bell you are notifying the neighborhood that there is a problem at your house.With the proper selection of a siren you can make the thieves visit very uncomfortable.

As you can see from the chart below it is fairly easy to provide ear-piercing noise:

110 decibel
Regular exposure of more than 1 minute risks permanent hearing loss.

100 decibel
No more than 15 minutes of unprotected exposure recommended.

85 decibel
Prolonged exposure to any noise at or above 85 decibels can cause gradual hearing loss.

How Loud is Too Loud?

Decibels Sound Source

  • 150 Firecracker
  • 120 Ambulance Siren

  • 95 Motorcycle
  • 90 Lawn Mower
  • 85 Heavy City Traffic
  • 60 Normal Talking
  • 40 Refrigerator Hum

Typical alarm panels provide adequate interior sirens but they are not loud enough to drive off an intruder. They are usually in the 85 db range. This amount of noise is adequate but not loud enough to drive an intruder out the door.

Install multiple Interior Sirens

The typical home security alarm panel installation will have one siren located in a hallway by the bedrooms. This location is best if you are only installing one siren. This location will alert you to an intrusion if you are in bed or if you have a smoke detector installed it will alert you in case of a fire. This one location is not adequate if you are trying to drive an intruder out of your house. You can install multiple sirens in your home in key locations that will drive an intruder out the door.

You can contact your home security installation professional to add an additional siren. The cost should be minimal depending on how many sirens you are adding. This type of installation can also be achieved by do it yourselfer’s in most cases. There may be additional programming depending on the amount of current that the new sirens will use and the output for the additional sirens may need to be turned on.
