The Executive
A typical alarm system involves a premise control unit (PCU), also known as the alarm control panel. This is essentially the executor of the alarm system. It reads sensor inputs, arms and disarms the alarm, and detects signal intrusions. In modern systems, the premise control unit consists of a circuit board, and a visual display screen. Also, the PCU is accompanied by a power supply so that the alarm system cannot be cut.
The recognizance unit of an alarm system is no doubt the sensors. They are usually placed around the perimeter of a house to alert the PCU if an intruder is present. From here the PCU can do two things: trigger a light on the property to expose and frighten the intruder, or sound the alarm. Sensors can be almost anywhere, but the most crucial positioning is the front door, back door, and vulnerable windows.
Schlagen Alarm!
Many alarm system involve bells, whistles, sirens and flashing lights to indicate the detection of an intruder. The nerves of a criminal perpetrating a burglary are no doubt on edge. Triggering an alarm will spike those nerves and cause the criminal to scurry away. Although catching the burglar safely is ideal, most criminals will stay far away from your property after they realize it’s protected by an alarm.
In addition to these features most alarm systems are accompanied by a monitoring service. In the event of an intruder, the PCU will contact a central operating system which will take the appropriate steps to secure the safety of your home.
