ADT alarm siren is a classic option. Everybody knows that the company does a good job when it comes to home alarms and safety. The design is cutting-edge. Any burglar who sees the system will know the house has a connection with the police. And the alerts are loud enough to scare them away.

Pros:

  • Output: 100 dB
  • 2-year battery for their outdoor siren
  • 433.92 Mhz operating frequency
  • Strobe light for visuals
  • Wireless system
  • Loud and custom alerts
  • New and better design

Cons:

  • Compatible with very few systems
  • The output cannot be customized
  • No tech support available

ADT is wireless so the system works without any cables or interruptions. Plus, owners can program their systems to add lights to the loud sound that will scare criminals away. It’s very simple to do. The only thing customers need is their master key. So, the product cannot be used in isolation. Still, on the negative side, these security sirens are only compatible with certain systems. As a result, they are a bit limited. And a waste of money if one does not know about this issue. The battery lasts a long time, making sure that the device works even if there is a power cut.

Or it can integrate within a bigger system of cameras. The steps are easy, owners just need to have used their password. Then, they have to enter the Keypad and add a new device. In terms of sound, the product can be very loud. On the negative side, owners cannot adjust it to be a little bit quieter. Plus, the new equipment can be pricey for so few features.

This is a comprehensive system instead of an alarm device. The best part is the integration with a smart home. The alarm siren does not work alone but in combination with the cameras and system in general. Yet, this makes the price very expensive for those with a tight budget.

Pros:

  • Keypad and motion sensors included
  • No use of passcodes
  • Combination with an app
  • No rush chiming
  • Personalized Net tags
  • Decide on Quiet Open settings
  • Pathlights available

Cons:

  • Very expensive
  • Not possible to buy only the siren
  • Too many options for newbies

The best thing about Nest is the custom options. For example, customers can choose how much time they need before the alarm goes off once people enter the house. It is also possible to decide on the dB of the siren in case there are thieves. There is also a No Delay that one can apply at night. Families can also keep an eye on their kids to have them safe. Every time kids leave using the back door, for instance, parents can get a message on their phones. Plus, the lights will help the owner find their way in the dark.

The Dome has 95 dB sounds and lights that flash at the same time. The idea is for this product to be an accessory of the Ring Alarm system. Those who don’t own one, then, cannot make use of it. Another nice feature is that it is not so loud so as to make the owner’s ears hurt.

Yet, if any of the buyers have issues or questions, they can contact their customer care team. They work from Monday to Friday during business hours. Finally, the device is very hard to see from afar. Nobody will be able to see the device or remove it without the owner’s word.

Consider These Features for the Best Purchase

Before buying, don’t forget to gauge every feature that makes alarm sirens perfect. Another important step is to read reviews and comments online to make sure the device truly suits one’s needs.

Protection Against the Weather

Most alarm sirens are used outdoors. This way, they can detect when criminals try to break into the house. This means that the device needs to have some protection against the weather. If not, they would be ruined in a very short time. Good products are protected against wind, dust, cold, and rain.

Setting it Up

Depending on the system, this can be a messy process. Anyone who wants to buy it should think twice if the setup is pro or DIY. The first one is more convenient for those who can afford it. But DIY is great for owners who have tools of their own.

Wireless or Not

There are two types of configurations for alarm sirens. The Wireless needs the Internet to work, but it does not require any wires. The negative point is that, if there is a power cut, the system will not function well. The other one is great but installing the system with wires is not that simple.

How to Plug It

Nobody wants their alarm siren to go off when they need it. That is why most of them come with dual systems. On the one hand, it is possible to plug them into electric power using wires. But they also include batteries in case there is a cut or a storm.

How Many DB Do They Have?

Some devices are louder than others. It all comes down to the needs of the buyer. If they would like to protect noisy places, then it’s better to buy alarm sirens with over 100 dB, for example. Houses can have less noise if needed.

Can Be Seen by Criminals

People who would like to scare off thieves and burglars should buy devices that can be seen from afar. This way, these criminals will see that the house is protected. And might decide to go and commit a crime somewhere else.

Seen by the Police

Finally, security siren’s lights help the police and other security guards spot one’s home in just seconds. Then, they will be able to help in a short time in case of an emergency.

Frequently Asked Questions

  • What Is the Loudest Siren?

    There is no definite answer to this question. Still, there are sounds that are loudest than others. Up to 125 dB is acceptable for the human ear. Then, it can cause severe damage. It’s true that security sirens are not meant to be nice. But, in case of false positives, owners should be protected against their own products.

  • How Loud Is a House Alarm?

    It depends on the brand. Normal alarm sirens go between 110 and 115 dB. This is a healthy range for the human ear. Yet, there are some others that go way above these numbers. And even if they are great to scare off criminals, it can harm the owners with their loudness.

  • How Do You Disable a House Alarm?

    It depends on the brand. All of them have different mechanisms. Yet, almost all equipment have in common a panel with a master key. This number usually comes with the device, but owners have to change it and remember it. So, the client only needs to look for the panel and enter the key to make the sound stop

  • Will My House Alarm Go off If the Battery Dies?

    Yes, it can happen. Unless security sirens are also plugged to electric power. Most equipment comes with this dual way of working to prevent this issue. In this way, clients have double protection to ensure their products work at all times.

  • Can Spiders Set off House Alarms?

    Yes, it can happen. Especially if the outdoor siren is very sensitive. In fact, reports show that 30% of house systems are triggered by insects. But how does this happen? Well, the only thing it needs is for the spider to crawl over the sensor. The device, then, will detect motion and start ringing.

  • How Do I Disarm My Alarm System?

    It’s not a hard process. Anyone can disarm their own system, as long as they know how it works. The most important part that the owner needs to remember is the Master Code. The provider will give this code to buyers. These people can change it later. With this code, the alarm will not set off anymore.

Scare Off Thieves

Security sirens are a strong complement to add to one’s security plan. With their strident sounds, they will scare anyone with bad intentions away. Plus, most of them include strobe lights that can guide owners into their homes with ease. Consider all the ones present in this review before purchasing the best one.
