The alarm system is an important gadget as it warns people of impending or current demise to their property. While there are many types of alarm systems depending on the home owner’s protection needs, there are some common features that can be noted.
Most alarm systems have back-up batteries. These comprise sealed lead acid storage batteries. There can also be other forms of emergency sources like generators and their main function is to supply energy in the event of a primary power failure.
Another component that is critical for an alarm system is what is referred to as initiating devices and they serve as input for the alarm system which can be automatically or manually activated. Some examples of initiating devices are pull stations and smoke detectors. Alarm sirens are what is heard as the alarm is triggered. They give the audible warning to the burglar that they have been detected and also inform those concerned that something is amiss. Consequently, action can then be taken various ways.
Strobe lights are other parts of alarm systems that also serve to warn those concerned that there is a problem. Also called stroboscopic lamps or strobes, these are regular devices used to produce regular flashes of light to warn that there has been a disturbance to the alarm system. It uses a xenon flash lamp or a plain flash lamp. In case of a breach to the security system, a cellular communicator, sends alarm signals to central station and encourages prompt action to allow the business owner to stay connected to their business from anywhere in the world. This device is sometimes referred to as the digital auto-dialer.
Also of importance in the alarm system, is the alarm siren driver. These serve the purpose of generating the alarm tone. Alarm siren drivers have a 12 volt input and are typically installed in the panel while the actual audible are the speakers. Alarm speakers, on the other hand, are the actual producers of the alarm noise and they need to be properly pitched so that they are loud enough and are of good quality.
