Alarm systems are designed to detect intruders and alert authorities to the occurrence. These systems range from small, DIY home security kits to large commercial ones that can integrate with video surveillance equipment. Some businesses need a simple system with motion sensors and glass break detectors, while others require a more sophisticated setup to monitor the activities in their warehouse, storefront or office. Regardless of the size, configuration or integration capabilities of the security system, most are built with a central control panel that manages all sensors and other components and transmits alarm signals to the police.
Most alarm systems use a bell, loud buzzer or other sound source to notify intruders of intrusion. Installation of the sounder starts with mounting it in a place where it will be heard and installing the circuit that runs from the switch to it. Once the circuit is completed, the sounder operates by battery and is not affected by power outages.
Door and window sensors work the same way as any other sensor in your system. There are two pieces that make up the sensor: one that is installed on the actual door or window and another mounted on a door frame or window sill. When the door or window is closed, the two sensors touch and create an electrical circuit that activates the alarm system if it’s armed.
If the alarm is triggered while you are home, you can manually turn off the system by using your keypad or smartphone app to disarm the system. You can also install a panic button that can be used to trigger the system when you feel threatened or are in a medical emergency. Some companies offer 24/7 monitoring services, which means the company will contact the police to handle an intrusion or medical emergency.
You might need a permit to install a self-monitored alarm system. The requirements vary by region. If you’re not sure, check with your local municipality. You may also need a permit if the alarm includes a siren that will call the police to your home.
Some systems are hardwired and run off your home’s electrical power to communicate with the control panel, while other systems are wireless and operate on cellular networks. A wired system is more reliable in that it won’t be interrupted by interference from other radio signals and won’t suffer from network outages. However, burglars know that they can cut a telephone line to disable a system.
A professional security company will help you determine which type of system works best for your needs and recommend the proper hardware to ensure that your system is properly integrated. They will also provide installation, maintenance and troubleshooting services. Those who are not able to afford a professional alarm system can buy an inexpensive DIY kit that is fairly easy to install. Many kits come with all the necessary parts and can be connected to your home’s Wi-Fi router.
Whether you’re an electrician looking to add this service or simply want to learn how to install an alarm system, you can take a hands-on practical course at a training center near you that offers courses on different types of systems, installation procedures, wiring and maintenance. The courses also include a written exam and a practical assessment.
