With offices in Dungiven, Belfast, Newry, Enniskillen and Strabane, our qualified fire alarm engineers deliver BS 5839 compliant systems for commercial, industrial and residential properties throughout all six counties.

Fire safety is not optional — it is a legal requirement. The Fire and Rescue Services (Northern Ireland) Order 2006 places a duty on the responsible person to ensure that adequate fire detection and warning systems are in place. Advanced Overwatch helps building owners, landlords, facilities managers and business operators meet these obligations with professionally designed and installed fire alarm systems that comply with all relevant British Standards and regulatory requirements.

Our BAFE registration (the British Approvals for Fire Equipment scheme) provides independent third-party certification that our fire alarm work meets the highest standards of quality, competence and reliability.

Types of Fire Alarm Systems

The type of fire alarm system required depends on the size and complexity of the building, the level of risk, the occupancy type and the applicable British Standard category. Advanced Overwatch installs all major types of fire alarm system:

Conventional Fire Alarm Systems

Conventional systems divide the building into zones, with detectors wired in circuits back to the main control panel. When a detector activates, the panel identifies the zone but not the individual device. Conventional systems are cost-effective and well-suited to smaller buildings with straightforward layouts such as small offices, shops and community buildings.

Addressable Fire Alarm Systems

In an addressable system, every detector and call point has a unique address on the loop. When a device activates, the control panel identifies the exact device location, enabling faster investigation and response. Addressable systems are essential for larger buildings, complex layouts and premises where rapid identification of the fire location is critical.

Analogue Addressable Fire Alarm Systems

Analogue addressable systems represent the most advanced form of conventional fire detection. Each detector continuously reports its environmental readings (smoke density, temperature) to the control panel, which uses intelligent algorithms to distinguish between genuine fire conditions and false alarms. These systems offer superior false alarm management and are the preferred choice for hospitals, schools, hotels and large commercial buildings.

Wireless Fire Alarm Systems

Wireless fire alarm systems use radio frequency communication between detectors and the control panel. They are ideal for listed buildings, heritage properties and premises where installing cabling would be impractical or prohibited. Modern wireless fire alarm systems meet the same British Standards as wired equivalents and are fully approved for use in all building types.

Fire Detection Devices

Selecting the correct detection devices is critical to ensuring rapid fire detection whilst minimising false alarms. Advanced Overwatch specifies and installs the full range of fire detection technologies:

• Optical smoke detectors — detect visible smoke particles using a light-scattering principle. Ideal for detecting slow-smouldering fires in offices, bedrooms and corridors.
• Heat detectors — respond to rises in temperature rather than smoke. Used in kitchens, boiler rooms, garages and other areas where smoke detectors would cause false alarms.
• Multi-sensor detectors — combine optical smoke and heat detection in a single device, using algorithms to analyse both inputs simultaneously. Multi-sensor detectors offer the best combination of fast detection and low false alarm rates.
• Beam detectors — project an infrared beam across large open spaces such as warehouses, churches and atriums. When smoke interrupts the beam, an alarm is triggered. Beam detectors are ideal for protecting areas with high ceilings where point detectors would be impractical.
• Aspirating smoke detection (ASD) — a network of sampling pipes continuously draws air from the protected area into a highly sensitive detection chamber. ASD systems such as VESDA can detect smoke at extremely early stages, making them essential for data centres, server rooms, clean rooms and high-value storage areas.
• Manual call points — allow building occupants to manually trigger the fire alarm. Required at every exit point on every floor as specified by BS 5839.

Fire Alarm Design & British Standards

All fire alarm systems must be designed in accordance with the relevant British Standards. Advanced Overwatch designs fire alarm systems to comply with:

BS 5839-1: Commercial & Non-Domestic Premises

BS 5839 Part 1 covers the design, installation, commissioning and maintenance of fire detection and alarm systems in non-domestic premises. The standard defines several system categories:

• Category L1 — protection throughout all areas of the building, providing the earliest possible warning of fire.
• Category L2 — protection of escape routes and rooms adjoining escape routes, plus areas of high fire risk.
• Category L3 — protection of escape routes only, including corridors, stairwells and lobbies.
• Category L4 — protection of escape routes within circulation areas only (corridors and stairways).
• Category L5 — protection of specific areas identified by a fire risk assessment.
• Category M — manual fire alarm system with call points only, no automatic detection.
• Category P1 — property protection throughout the entire building.
• Category P2 — property protection in defined areas only.

BS 5839-6: Residential Premises

BS 5839 Part 6 covers fire detection and alarm systems in residential properties including houses, flats and houses in multiple occupation (HMOs). The standard specifies minimum grades and categories of system depending on the property type and risk level.

Commercial Fire Alarms

Advanced Overwatch designs and installs fire alarm systems for all types of commercial and non-domestic premises, including:

• Offices — Category L3 or higher depending on risk assessment, often with integration to access control and building management systems.
• Retail premises — addressable systems with zoning to enable phased evacuation in larger stores and shopping centres.
• Manufacturing & warehousing — specialist detection including beam detectors and aspirating systems for large open areas with high ceilings.
• Healthcare facilities — analogue addressable systems with staff alarm and staged evacuation capabilities to protect vulnerable patients.
• Education — schools, colleges and universities requiring robust systems with anti-vandal devices and high false alarm resilience.
• Hospitality — hotels, restaurants and licensed premises with overnight sleeping risk, requiring Category L1 or L2 systems with voice alarm integration.

Residential Fire Alarms & Landlord Obligations

Landlords in Northern Ireland have a legal duty to ensure that their rental properties are fitted with adequate fire detection. The specific requirements depend on the property type:

• Standard rental properties — must have working smoke alarms on every floor and a carbon monoxide detector in rooms with solid fuel appliances.
• Houses in Multiple Occupation (HMOs) — require a fire alarm system designed and installed to BS 5839-6, typically Grade A Category LD2 with a central control panel, mains-powered detectors and monitored sounders.
• Purpose-built flats — building regulations require compliant fire detection in accordance with BS 5839-6.

Advanced Overwatch helps landlords meet their obligations with fully compliant fire alarm installations, regular maintenance and certification for HMO licensing applications.

Fire Alarm Monitoring

For premises where rapid fire brigade response is essential, Advanced Overwatch provides 24/7 fire alarm monitoring through approved Alarm Receiving Centres (ARCs). When the fire alarm activates, a signal is transmitted to the ARC, which immediately contacts the Fire and Rescue Service.

Our monitoring solutions include:

• Dual-path signalling — using both broadband/IP and mobile network paths to ensure the alarm signal reaches the ARC even if one communication path fails.
• RedCARE and Dualcom — BT RedCARE and CSL Dualcom are the two most widely used alarm signalling platforms in the UK and Ireland, both providing verified, high-integrity communication paths.
• Cause and effect programming — automated responses such as releasing fire doors, activating emergency lighting and shutting down ventilation systems when the fire alarm activates.

Fire Risk Assessments

Under the Fire and Rescue Services (Northern Ireland) Order 2006, the responsible person for every non-domestic premises must carry out a suitable and sufficient fire risk assessment. This assessment must identify fire hazards, evaluate the risk to people, and determine what fire safety measures are needed — including fire detection and alarm systems.

Advanced Overwatch can assist with fire risk assessments, helping you identify where your current fire protection measures may fall short and recommending appropriate upgrades to bring your premises into compliance.

Maintenance & Servicing

BS 5839-1 and BS 5839-6 specify minimum maintenance requirements for fire alarm systems. Failure to maintain your fire alarm system can result in enforcement action, invalidated insurance and, most critically, a system that fails to detect a real fire.

Advanced Overwatch offers comprehensive fire alarm maintenance contracts including:

• Quarterly inspections — visual checks, functional testing of a proportion of devices and system log review as required by BS 5839.
• Annual service visits — comprehensive testing of every device including sensitivity checks on smoke detectors, battery load testing and full system function verification.
• 24/7 fault response — priority callout for maintenance contract customers to investigate and resolve system faults.
• Detailed service records — full documentation of all maintenance activities for compliance, insurance and regulatory audit purposes.
• Life safety upgrades — proactive identification of ageing components that need replacement before they fail.

Integration with Other Fire Safety Systems

A fire alarm system is often just one element of a building’s overall fire safety strategy. Advanced Overwatch can integrate your fire alarm with:

• Emergency lighting — maintained and non-maintained emergency lighting systems that activate automatically when the fire alarm triggers or mains power fails.
• Fire suppression systems — interfacing with sprinkler systems and gas suppression systems for server rooms and specialist areas.
• Access control — automatic release of access-controlled doors on fire alarm activation to ensure unimpeded evacuation.
• Public address & voice alarm — clear voice messages to direct occupants during evacuation, replacing or supplementing traditional bell sounders.
• Building management systems — integration with BMS for HVAC shutdown, lift recall and smoke ventilation activation.
