If you’ve purchased a burglar alarm, there are several factors to consider. Some of these systems will work for your home and others will only work for one location. The type of alarm you get will depend on what you want to protect. The most popular types are the closed-circuit and open-circuit systems. A closed-circuit system will shut off electric current around your perimeter and a tripped alarm will send an alert. On the other hand, an open-circuit system only triggers the alarm when it detects movement in an area.
Most burglar alarms work on an electricity-based circuit built into the entranceway. When an electrical current flows between two points with opposite charges, the circuit is closed. When the door is closed, the electricity will flow and activate the alarm. If the door is left open, however, the circuit is not closed and the alarm will sound. If someone tries to break into your home or office, the battery will go dead. Once the battery runs low, the power will shut off the circuit and trigger the alarm.
A burglar alarm system will be linked to a control panel so that it can monitor the situation. When a circuit break occurs, an alarm countdown begins. If the burglar doesn’t enter a code to disable the system, the alarm will sound. The alarm will be audible and alert the occupants of the building. If the intruder doesn’t exit the building, the sounder will continue to sound until the intruder has moved on.
