Fire alarm systems in Al Marjan Island 

Fire alarm systems in Al Marjan Island: local context

Al Marjan Island is a group of reclaimed islands off Ras Al Khaimah's coast developed for resorts, hotels and residential towers, with major hospitality projects under way. Building stock is dominated by hotels and high-rise residential. Several large integrated resort projects are under construction, bringing high-rise hotel and residential towers to what was previously a low-rise emirate, and with them the full range of tower MEP requirements such as pressure zoning, stair pressurisation and high-capacity fire pumps.

• Island location means extreme salt exposure, so marine-grade equipment and corrosion protection are essential.
• Hotels need central plants, fresh-air dehumidification, hot water with Legionella control and kitchen extract.
• Access over the causeway and limited laydown space on the island mean deliveries of large plant must be scheduled and staged carefully.

Building types we serve in Al Marjan Island

For high-rise towers, the work concentrates on pressure-zoned water and drainage stacks, riser and plant-room coordination, stair pressurisation and a cooling source sized for diversity across dozens of typical floors.

Scope of work

• Supply and installation of addressable control panels, repeaters, detectors, manual call points, sounders, beacons and interface modules to approved shop drawings.
• Installation of fire-rated cabling, containment and segregation from power circuits, with loop routing that keeps a single cable fault from disabling an entire floor.
• Interface wiring with sprinkler flow and tamper switches, fire pumps, gas suppression panels, kitchen hood systems and the building management system.
• Device-by-device testing with smoke and heat test equipment, sound pressure level checks in occupied rooms, and full cause-and-effect witness testing with all trades.

Systems we install

• Addressable fire alarm control panels networked across buildings or podium and tower zones.
• Beam detectors and aspirating detection for atria, warehouses and high ceilings.

UAE site and climate challenges

• Roof plant rooms and electrical rooms run hot during the day, which shortens battery life in panels and power supplies. We locate panels in conditioned space where possible and size standby batteries with temperature derating in mind.
• Kitchens in hotels and villas generate heat and steam that defeat smoke detectors. Rate-of-rise or fixed-temperature heat detectors are used there, with the hood suppression system interfaced into the main panel.
• Voice evacuation versus bells and sounders: voice systems allow phased evacuation in towers and hotels and give clearer instructions, but need speaker coverage design, amplifier rooms and intelligibility testing in every space.
