A Central Battery System is a single, centralised power backup unit — typically housed in a dedicated plant or electrical room — that simultaneously supplies backup electricity to every emergency luminaire, exit sign, and safety light in a building the moment mains power fails.
Think of it as the “heart” of your building’s emergency lighting network. Instead of every individual light carrying its own small battery — which degrades at different rates and is nearly impossible to inspect reliably — a CBS puts all the backup power in one controllable, monitorable, testable location.
Dubai Civil Defence (DCD) mandates a DCD approved central battery system or equivalent emergency lighting central battery solution for all commercial buildings, high-rise towers (G+4 and above), hotels, hospitals, malls, warehouses, and factories under the Dubai Fire Protection Code of Practice Part 11 and the relevant clauses of BS 5266-1 and EN 50171. Without it, you will not receive a DCD Completion Certificate — and your building cannot legally be occupied.
Dubai Fire Protection Code — Part 11 (Emergency Lighting), BS 5266-1:2016, and EN 50171:2001 require that emergency lighting systems in commercial buildings are powered by a maintained, tested, and documented central backup power source. Non-compliance during DCD inspection results in failed certification and potential building closure.
CBS vs Self-Contained

How It Works
Understanding the sequence of operation helps you see why CBS is far more reliable than any decentralised alternative — and why DCD engineers check each of these stages during inspection.
During everyday building operation, the CBS charging unit continuously monitors and maintains the central battery bank at full charge. The control panel displays all circuit statuses in real time — green means ready, any fault triggers an immediate alert to building management.
The moment DEWA mains supply drops, the CBS control panel detects the failure within milliseconds. No manual intervention is needed — the system is fully automatic and operates 24/7 regardless of whether a technician is on site.
The Automatic Transfer Switch (ATS) switches all emergency lighting circuits from mains to battery power in under 0.5 seconds. This meets BS 5266 and DCD requirements for maintained and non-maintained emergency lighting.
The inverter module converts DC power stored in the battery bank to AC power suitable for connected emergency lights, exit signs, staircase luminaires, and other life-safety loads throughout the building — simultaneously, across all circuits.
The battery bank is sized to provide a minimum 3-hour continuous backup (DCD standard), giving occupants safe evacuation time and emergency services adequate working light. Extended duration options (5–8 hours) are available for hospitals and critical facilities.
When DEWA mains supply is restored, the CBS automatically switches back and begins recharging the battery bank to full capacity. The control panel logs the event with a timestamp — providing the DCD-required documented evidence of system operation.
System Components
Every component we supply for emergency lighting central battery systems in Dubai is BS 5266 / EN 50171 certified and sourced from manufacturers approved for use under Dubai Civil Defence regulations.
System Type
The right CBS type depends on your building category, total emergency load, and DCD design approval requirements. Our engineers assess your site and recommend the most practical and cost-effective solution.
Emergency luminaires are always powered by the CBS — both during normal operation and during power failure. The light level remains constant at all times.
Emergency luminaires are normally off, and switch on only when mains power fails. This reduces energy consumption in areas not in continuous use.
A hybrid system where some luminaires are maintained (always on) and others are non-maintained (only on during failure). Designed to maximise coverage while minimising energy use.
Hospitals, data centres, and other critical infrastructure require extended backup duration beyond the standard 3 hours. We design high-capacity systems using high-cycle battery technology.

Industries We Serve
Every building, every industry, every risk profile is different. That’s why we don’t offer one-size-fits-all systems. Here’s how we protect Dubai’s most important sectors:
To provide innovative, reliable, and compliant fire safety and security solutions. As a Dubai Civil Defense-certified contractor, we specialize in fire protection systems, offering expert installation, maintenance, and high-quality fire suppression and firefighting products to ensure the safety of people and properties across the UAE.
To be the trusted leader in fire safety and security solutions, recognized for our excellence in service, cutting-edge technology, and unwavering commitment to protecting lives and assets. We aim to set industry standards for safety, reliability, and customer satisfaction in every project we undertake.
At Abdullah Fire Safety, we believe that every emergency lighting system should perform flawlessly when it matters most. A Central Battery System is more than electrical equipment. It is a life safety solution that protects occupants during emergencies and supports safe evacuation.
That is why every project we undertake is guided by three core principles: strict Dubai Civil Defence compliance, precision engineering, and uncompromising quality. From initial design and installation to testing, commissioning, and ongoing maintenance, we follow industry best practices to deliver systems that are reliable, efficient, and built for long-term performance.
Our commitment is simple: provide every client with a solution that meets regulatory requirements, minimizes operational risks, and gives complete confidence that their emergency lighting system will perform when it is needed most.
Many contractors install whatever battery system is cheapest at the time. As a dedicated central battery system supplier in Dubai, we stock genuine BS 5266 / EN 50171 certified units, spare inverter modules, and replacement battery banks — so your AMC technician never waits weeks for a part to arrive from overseas. This is one reason our average emergency repair time beats the market standard.
Annual Maintenance Contract (AMC)
Installing a CBS is only the beginning. Dubai Civil Defence requires documented, regular testing at three intervals — and a missed test is a failed inspection. Our AMC covers all of this automatically, so you never have to worry about compliance dates.
Our Annual Maintenance Contracts are priced per system — not per visit. One fixed annual fee covers all scheduled and emergency visits, full DCD compliance documentation, and priority response.

Questions we get from facilities managers, building owners, and consultants every week — answered plainly.
A Central Battery System is a centralised power backup unit that powers all of a building’s emergency lights, exit signs, and safety luminaires from one location when mains electricity fails. It uses a battery bank, an inverter module, a control panel, and an automatic transfer switch. In Dubai, DCD requires CBS in commercial buildings G+4 and above, hotels, hospitals, malls, warehouses, and industrial facilities under Fire Protection Code Part 11 and BS 5266-1.
Yes. Dubai Civil Defence (DCD) mandates an approved emergency lighting backup system — typically a CBS — for all commercial buildings (G+4 and above), hotels, hospitals, shopping malls, schools, warehouses, factories, and high-rise residential towers. Without DCD approval of your CBS, your building will not receive a Completion Certificate and cannot legally be occupied for its intended use. Annual CBS maintenance and testing is also required to maintain this certification.
For a mid-sized commercial building (10–20 floors), CBS installation typically takes 7–14 working days, including site survey, DCD design submission and approval, equipment procurement, installation, testing, and commissioning documentation. Larger buildings or projects requiring TRAKHEES approval may take slightly longer. We always give you a realistic timeline in writing before starting.
Dubai Civil Defence and BS 5266-1 require three types of regular testing: (1) Monthly functional test — simulate mains failure, confirm all lights activate within 0.5 seconds; (2) Quarterly partial duration test — run the system on battery for 1 hour, check lux levels and battery condition; (3) Annual full duration test — 3-hour discharge test with full battery capacity verification and updated DCD compliance report. Our AMC covers all three, plus 24/7 emergency call-outs.
A maintained system keeps all connected emergency luminaires powered at all times (both during normal operation and power failure). A non-maintained system keeps the lights off during normal operation and only switches them on when mains power fails. DCD and BS 5266 specify which type is required depending on the area’s use — hotel corridors, exit signs, and staircases typically require maintained, while storage areas and warehouses may use non-maintained. Our engineers specify the correct type in the DCD design submission.
We supply and install CBS units from DCD-approved and BS 5266 / EN 50171 certified manufacturers including Eaton, Chloride, Legrand, Safetynet, Hochiki, Menvier, and Edwards. We recommend the brand and model that best fits your building’s load requirement and budget — and we do not push a single brand for commercial reasons.
Yes, this is a common service we provide. We assess your existing CBS, determine whether it requires battery replacement, inverter module repair, a full unit replacement, or system expansion, and then manage the new DCD design submission for any significant changes. We also provide CBS repair services for existing installations with specific fault conditions.
Completely. We prepare the CBS design drawings, load calculations, and technical specifications for DCD submission, handle all correspondence with DCD inspectors, arrange the on-site inspection, and compile the Completion Certificate documentation package for you. This is included in every installation project we take on.
