Based on the principle of general alarm systems, burglar alarms used at houses, produce a loud noise when certain conditions are met. The closed circuit alarm current flow powers the alarm as opposed to the open circuit alarm which sounds when the current is shut off. There is just three principal components or major gear a burglar alarm system features – 1) the control panel, 2) indicating device and 3) detectors, which require to be interlinked for it to function. With the use of radio transmitters and receivers the system connects to the radio controlled system, still infrared frequency and other programs could also be used.
Control panel- The control panel is the primary control mechanism that allows the user to input specific information about the home or building. You can turn on, off, or readjust the alarm system on the board or access the same parts with remote control keypads. If the detectors detect any unusual activity they will transmit this information to the control board and the alarm will activate. Signal systems – This type of alarm system emits a noise if certain circumstances occur in order to trigger it. sounders in intruder alarm systems are usually noisy enough to instill panic in the burglar and may also be bells, buzzers, or chimes. Today, warning buzzers are sometimes combined with a rotating strobe light. Common strobe colors are red, yellow, and blue. Signaling equipment might include speed dialers or a phone relay.
Detectors – Another term for sensing components, sensing elements are mechanisms that report unusual motions to the control board. There are several types of sensing elements that are used for a burglar alarm system, below are some of the commonly used detectors: Magnetic Contact detectors – this detector is ordinarily set-up at the corners of your doors and windows.
IR emanation detection equipment – these are principally contrived to activate when unsanctioned motion is observed but they can also register shifts in temperature.
A vibration sensor is more sensitive than a magnetic contact sensing element and can detect any small vibration that may be established to be evidence of an intruder about to enter the premises and trip the alarm.
