FAQs

Sigma Fire & Security offers end-to-end fire protection and security solutions across London and Kent. Our core services include fire alarm systems, CCTV surveillance, intruder alarms, access control, AOV systems, and service contracts with full monitoring and maintenance.

We design, install, and maintain systems compliant with British Standards like BS 5839 and BS 5306, ensuring full safety and insurance compliance for both domestic and commercial clients.

The ideal fire alarm depends on your premises’ layout and risk category. Addressable fire alarms are best for larger or more complex buildings – they identify exactly which detector is activated. Conventional fire alarms suit smaller properties or retail units and are more cost-effective.

Our engineers conduct comprehensive fire risk assessments across London and Kent to specify systems that meet BS 5839 and your local fire authority’s standards.

Fire alarms must be serviced at least twice per year, and fire extinguishers annually, as per the Regulatory Reform (Fire Safety) Order 2005. Regular inspections ensure your systems remain reliable and compliant.

Sigma Fire & Security provides scheduled maintenance plans, complete with detailed reports, testing, and certification to keep your fire systems up to code and your insurance valid.

A monitored system ensures that when an alarm is triggered, a response centre or the authorities are immediately notified — providing 24/7 protection. This is crucial for vacant properties, retail units, and offices across London and Kent where rapid response can prevent loss or damage. Our NSI-approved monitoring service offers instant alerts, reducing false alarms and improving emergency response times.

CCTV acts as both a deterrent and evidence tool. Our IP-based CCTV systems feature HD cameras, motion detection, cloud storage, and remote access from your smartphone or PC.

Businesses in London and Kent use Sigma systems to monitor live footage, investigate incidents, and ensure staff and customer safety — all while complying with GDPR and data protection regulations.

Automatic Opening Vent (AOV) systems are designed to remove smoke during a fire, allowing safer evacuation and easier firefighter access. They’re legally required in many multi-storey or residential developments. Sigma Fire & Security supplies and maintains AOV systems compliant with BS 7346-8, ensuring your property meets fire safety building regulations.

An integrated system connects fire alarms, intruder systems, CCTV, and access control into one networked solution. This ensures a coordinated response — for example, when a fire alarm activates, doors unlock automatically, emergency lights trigger, and cameras record the event.

Integration boosts safety, compliance, and operational efficiency, especially for large or multi-site organisations.

False alarms are disruptive and expensive. To reduce them:

• Maintain your systems regularly.
• Keep sensors and detectors free from dust or obstructions.
• Train staff properly on alarm operation.
• Install intelligent detection systems that distinguish smoke from steam or dust.
  Sigma Fire & Security uses advanced detection technologies designed to reduce false activations while maintaining accuracy.

Under the Regulatory Reform (Fire Safety) Order 2005, every commercial premises must:

• Have a fire risk assessment.
• Install adequate fire detection and warning systems.
• Maintain extinguishers, signage, and emergency lighting.
• Train employees in fire procedures.
  Sigma provides compliance audits, documentation, and certified systems to meet all UK fire regulations.

A fire risk assessment should be reviewed annually, or whenever significant changes occur (e.g., building renovations or staff increases). Our certified assessors inspect your property, identify hazards, and produce an actionable report that meets Fire Safety Order requirements.
