INTRUSION AND BURGLAR WARNING AND DETECTION SYSTEMS

Intruder and burglar alarm systems provide an early warning when unauthorised entry or suspicious activity is detected within a protected property. They are used to help protect homes, offices, retail premises, warehouses, schools, hotels, industrial facilities and other buildings against intrusion.

A properly designed alarm system can detect events such as a door or window being opened, movement within a protected area, glass breakage or activation of a panic button. Depending on the system, an alarm can trigger local sirens and visual indicators and send notifications to designated users through available communication networks.

The effectiveness of an intruder alarm depends on appropriate equipment selection, sensor positioning, system configuration and regular maintenance.

How Intruder Alarm Systems Work

A typical system uses a control panel as the central point for receiving and processing signals from different detectors.

Depending on the site and system selected, components may include:

Magnetic door and window contacts – detect the opening of protected doors or windows
PIR motion detectors – detect movement within designated areas
Dual-technology detectors – combine more than one sensing technology on selected systems
Glass-break detectors – monitor for characteristics associated with breaking glass
Panic or emergency buttons – allow an authorised person to manually initiate an alarm
Indoor and outdoor sirens – provide an audible warning when an alarm is triggered
Strobe lights – provide a visual alarm indication on selected installations
Keypads, tags or remote controls – provide authorised arming and disarming
Backup batteries – maintain operation during a mains power interruption
GSM/cellular, Ethernet or Wi-Fi communication modules – provide remote notifications where supported

The exact combination depends on the building layout, security risk, communication infrastructure and operating requirements.

Wired, Wireless and Hybrid Alarm Systems

Intruder alarms can be configured using wired, wireless or hybrid technology.

Wired Systems

Wired detectors are connected to the control panel using cables. They can be suitable for new buildings, major renovations and premises where permanent cabling can be installed discreetly.

Wireless Systems

Wireless sensors communicate with the alarm control panel without requiring a dedicated cable connection to every detector. They can be useful where extensive cabling would be difficult or disruptive.

Wireless devices still require appropriate battery management and reliable communication with the control panel.

Hybrid Systems

Hybrid systems combine wired and wireless devices. This can be useful when extending an existing alarm installation or where different parts of a building present different installation challenges.

GSM and Remote Alarm Notifications

Some alarm systems can communicate an alarm event to authorised users through GSM/cellular networks or other supported communication methods.

Depending on the system configuration, notifications may include:

Alarm activation
Zone identification
Tamper events
Mains power failure
Battery-related events
System status notifications

The available notification method depends on the control panel, communication module, network availability and system configuration.

Where remote notifications are required, Solutions Unlimited can assess the available communication infrastructure before installation.

Applications in Kenya

Intruder alarm systems can be designed for different types of premises, including:

Residential Properties

Homes, apartments, gated residences and holiday properties can use door contacts, motion detectors, panic buttons and other sensors to protect selected entry points and internal areas.

Offices

Alarm zones can be configured for reception areas, offices, stores, server rooms and other restricted areas, depending on the security requirements.

Retail Premises

Shops and commercial outlets may use perimeter contacts, motion detection and panic buttons to provide additional protection outside normal operating hours.

Warehouses and Industrial Facilities

Large premises may require multiple alarm zones covering entrances, loading areas, storage sections and other vulnerable locations.

Schools and Institutions

Systems can be configured around administrative offices, laboratories, stores, equipment rooms and other areas requiring additional protection.

Hotels and Hospitality Facilities

Alarm systems may be used to protect service areas, stores, offices and other restricted sections without unnecessarily affecting guest areas.

Site Assessment and Alarm Installation

Effective installation begins with understanding the property rather than simply fitting detectors in every available room.

Before installation, Solutions Unlimited can assess:

Building layout and access points
Doors, windows and other potential entry points
Internal movement patterns
Areas requiring restricted access
Existing electrical and communication infrastructure
Sensor coverage requirements
Potential sources of unwanted activations
Requirements for remote notification
Positioning of the control panel and sirens
Backup-power requirements
Integration with other security systems

Sensor positioning is particularly important. A motion detector installed in the wrong location may have poor coverage or be exposed to environmental or operational conditions that can affect its performance.

The system is configured into appropriate zones, allowing individual areas or detection points to be identified when an event occurs.

After installation, the system should be tested to confirm detector operation, alarm activation, communications, audible/visual warnings, backup power and other configured functions.

Reducing Unwanted Alarm Activations

False or unwanted alarms can undermine confidence in a security system. Good system design helps reduce this risk.

Factors that should be considered include:

Correct detector selection
Appropriate mounting height and position
Movement patterns within the protected area
Pets and other sources of movement
Temperature and environmental conditions
Doors or windows that may be left open
Correct sensitivity and configuration
Regular maintenance

Some motion detectors provide pet-immunity features, but the actual performance and permitted pet size depend on the particular model and manufacturer specifications.

For this reason, detector selection should be based on the environment rather than simply choosing the cheapest or most readily available sensor.

Panic and Emergency Alarm Systems

A panic or distress alarm provides a means for an authorised person to manually initiate an alarm.

Depending on the application, panic buttons may be installed at:

Reception desks
Cashier points
Security offices
Banks and financial service areas
Retail counters
Management offices
High-risk work areas

Portable or wireless panic devices may also be available for selected applications.

The alarm response procedure should be clearly defined so that personnel know what happens after the button is activated.

Integration with Other Security Systems

An intruder alarm does not necessarily operate as a standalone system.

Depending on the equipment and project requirements, it can form part of a wider electronic security installation alongside:

Access control systems
Fire alarm systems
Intercom systems
Gate automation
Security lighting
Alarm monitoring services
Other compatible security platforms

Integration capabilities vary between manufacturers and models. Each proposed connection should therefore be confirmed against the equipment specifications before installation.

Maintenance and Technical Support

Regular maintenance helps identify faults before they affect the reliability of the alarm system.

Depending on the system, maintenance may include checking:

Detectors and magnetic contacts
Alarm sirens and visual indicators
Backup batteries
Control-panel condition
Communication modules
Panic buttons
Tamper circuits
Wiring and connections
Wireless device batteries
Event logs and system status

Battery-powered devices require particular attention because depleted batteries can affect system availability.

Solutions Unlimited provides technical support, maintenance and troubleshooting for installed security systems.

Selected products and services are supported by up to 2 years manufacturer warranty and 24/7 technical support, subject to the applicable product and service terms.

Intruder Alarm Systems for New and Existing Buildings

An alarm system can be incorporated during the construction or refurbishment of a building, when cable routes and equipment locations can be planned in advance.

Existing buildings can also be upgraded. In such cases, the installation approach may depend on the existing wiring, building finishes, accessibility of cable routes, current alarm equipment and the extent of protection required.

For an existing alarm system, replacing every component is not always necessary. A site assessment can determine whether selected components can be retained, upgraded or replaced.

Frequently Asked Questions

What is the difference between an intruder alarm and a burglar alarm?

The terms are commonly used interchangeably. Both generally refer to systems designed to detect unauthorised entry or intrusion and generate an alarm response.

What does a burglar alarm include?

A typical installation includes a control panel, detection devices, alarm siren, user interface and backup power. Additional components such as panic buttons, communication modules, glass-break detectors and external sirens can be added depending on the application.

Can an alarm system send an alert to my phone?

Yes, selected systems can send notifications through GSM/cellular networks, Wi-Fi, Ethernet or manufacturer-supported applications. The available method depends on the specific alarm system and communication infrastructure.

Will a burglar alarm work during a power outage?

Many systems incorporate a backup battery that allows the alarm to continue operating during a mains power interruption. Backup duration depends on the system configuration, battery condition and connected equipment.

Can I use a burglar alarm in an apartment?

Yes. An apartment can use an alarm system configured around its doors, windows and selected internal areas. The installation should take account of the building’s layout and any shared access arrangements.

Can an alarm system protect a warehouse?

Yes. Warehouses can use multiple zones and detection devices to protect entrances, storage areas, offices and other vulnerable sections. Larger facilities require careful sensor positioning and zoning to provide practical coverage.

Can a burglar alarm be connected to access control?

Some systems can integrate with access-control equipment. The exact integration depends on the control panel, access-control platform and communication protocols supported.

Can an alarm system be connected to a fire alarm?

Some security platforms can exchange signals with fire detection systems, but fire and intrusion functions should remain appropriately configured and managed. Compatibility must be confirmed before integration.
