What Is Burglar Alarm System & How Does It Works?

Intrusion and burglary are serious global issues that heavily impact commercial properties. Businesses, especially banks, are prime targets due to the valuable assets they hold. However, implementing robust security measures can drastically reduce these incidents. For example, banks with advanced burglar alarm systems have reported a significant drop in successful intrusion attempts, proving the effectiveness of these systems in protecting assets.

Given the high risk of intrusions, theft alarm systems have become essential components of modern security strategies. These systems are designed to detect unauthorized entry and promptly alert property owners and authorities, thereby preventing theft and damage. Investing in a reliable burglar alarm system not only enhances security but also provides peace of mind, knowing that your property is well-protected.

What is a Burglar Alarm System?

A burglar alarm system is a network of electronic devices designed to detect unauthorized entry into a building or area. These systems are primarily used to protect against burglary, vandalism, and other security threats. When a potential intrusion is detected, the system triggers an alarm, which can be audible, silent, or both, to alert property owners and authorities.

How Does a Burglar Alarm System Work?

1. Control Panel

The control panel serves as the central hub of a burglar alarm system. It is essentially the “brain” of the system, responsible for processing signals from various sensors and managing the overall operation of the alarm system. 

When a sensor detects potential unauthorised access, it sends a signal to the control panel, which then determines the appropriate response, such as activating an alarm or sending a notification. Modern control panels may also have integrated features for remote management via smartphone apps or web interfaces, providing users with real-time monitoring and control.

2. Sensors

Sensors are critical components that detect and alert the system to potential breaches. They are strategically placed at various entry points and sensitive areas to ensure comprehensive coverage. Here are some common types of sensors:

• Motion Detectors: These sensors monitor changes in movement within a designated area. They use technologies such as infrared, ultrasonic, or microwave to detect motion. When movement is detected, the sensor sends a signal to the control panel, triggering an alarm if necessary.
• Door/Window Contacts: These sensors are placed on doors and windows. They consist of two parts: a magnet and a contact switch. When the door or window is closed, the magnet and switch are aligned, keeping the circuit closed. If the door or window is opened, the magnet moves away from the switch, breaking the circuit and sending an alert to the control panel.
• Glass Break Sensors: These sensors are designed to detect the sound or vibration of breaking glass. Glass break sensors are sensitive to the specific frequency of glass breaking, which helps to minimise false alarms.

3. Alarms

Alarms are the audible and visual components of the burglar alarm system that are activated when a breach is detected. They serve to alert staff and deter intruders. Common types of alarms include:

• Sirens: These are loud, high-pitched sound devices designed to draw attention and scare off intruders. The sound produced by sirens is typically loud enough to be heard throughout a building and in nearby areas, ensuring that anyone in the vicinity is alerted to the potential threat.
• Strobe Lights: Strobe lights provide a visual alert in addition to the audible siren. They emit bright, flashing lights that can attract attention even in noisy environments. Strobe lights are particularly useful in situations where the sound of the siren may not be sufficient to alert all individuals, such as in noisy industrial settings or for individuals with hearing impairments.

4. Communication Devices

Communication devices are key for letting the property owner or monitoring centre know about any security breaches. They make sure that alerts are sent quickly, even if the owner isn’t around. Common communication methods include:

• Landline Connections: Traditional phone lines can be used to transmit alarm signals to a monitoring centre or directly to the property owner. While reliable, landlines are increasingly being replaced by more modern communication methods.
• Cellular Connections: Cellular communication uses mobile networks to send alerts and notifications. Cellular-based systems are more flexible and can function even if the landline is cut or unavailable. They are a popular choice for modern alarm systems due to their reliability and ease of use.
• Internet Connections: Alarm systems use internet-based communication to transmit alerts. This can be done through a dedicated internet connection or via a broadband network. Internet connections allow for remote monitoring and control through web-based platforms or smartphone apps, providing users with real-time updates and management capabilities.

Each of these components plays a crucial role in the effectiveness of a burglar alarm system, working together to provide a robust security solution.

Types of Burglar Alarm Systems

Burglar alarm systems come in various types to cater to different security needs and preferences:

1. Wired vs. Wireless Systems

• Wired Systems: These alarms use physical cables to connect the various components of the system. Wires run between the control panel, sensors, and alarms. 
• Wireless Systems: These alarms use radio signals to communicate between the control panel, sensors, and alarms. Wireless systems offer greater installation flexibility, as they don’t require physical wiring throughout the property. 

2. Monitored vs. Unmonitored Systems

• Monitored Systems: These systems are connected to a monitoring centre. When an alarm is triggered, the monitoring centre is notified and can take immediate action, such as contacting emergency services or the property owner. Monitored systems provide an added layer of security, ensuring that help is dispatched quickly if needed.
• Unmonitored Systems: Unmonitored alarms are not linked to a monitoring centre. Instead, they rely on loud sirens or other alert mechanisms to notify the property owner or people nearby of a breach. While these systems can be effective at deterring intruders with their noise, they may not provide the same level of response as monitored systems.

3. Audible vs. Silent Alarms

• Audible Alarms: These alarms produce loud sounds, such as sirens or horns, to alert people nearby and scare off intruders. The loud noise is designed to draw attention and can be effective at quickly alerting anyone in the vicinity of a security breach.
• Silent Alarms: Silent alarms do not make any noise when triggered. Instead, they send a discrete signal to the authorities or monitoring centre, which then takes action without alerting the intruder. This type of alarm is useful in situations where the goal is to quietly alert law enforcement while keeping the intruder unaware that their presence has been detected.

How to Choose the Right Burglar Alarm System?

1. Property Size and Layout

• Larger properties may need more sensors and a robust control panel.
• Complex layouts require careful placement of sensors to cover all entry points and sensitive areas.

2. Security Needs

• Identify critical entry points like doors and windows for sensor placement.
• Consider protecting valuable assets with specialised sensors such as glass break detectors or motion sensors.
• Evaluate high-risk areas that may require additional protection.

3. Technology Preferences
