Dublin Airport T2


Dublin Airport T2
DUBLIN ON CLOUD NINE WITH PROTEC’S CIRRUS CLOUD CHAMBER TECHNOLOGY

Dublin Airport T2


Dublin Airport’s New Terminal 2 in benefiting from reduced false alarms and more efficient operation following the installation of fire detection and alarm technology from Protec Fire Detection plc.

OVERVIEW

The installation of an air sampling fire detection system in the new second terminal at Dublin Airport is confidently expected to avoid the numerous false alarms that were suffered in the existing T1. Indeed, the system proposed by Protec was put on trial for a month in the old terminal and the sensitivity of the equipment adjusted over that period.

The new terminal has around 9000 m2 of retail and catering outlets, 58 check-in desks and provision for self-service and online check-in and baggage drop.

The experience of Protec at other airports such as Manchester International secured approval of the system from consulting engineers Arup.

Protec also proposed and used a number of innovative cost-saving interfaces. The most significant cost saver for the project came from using some clever integrated smoke damper control interfaces to use the wiring loop of the fire detection and alarm system for other purposes. The system controls all the cold smoke dampers for the terminal and removed the need to provide a separate control circuit for smoke dampers. The cost saving was around Eu200 000.

The trial of the Cirrus air sampling detector system led to the installation of 120 units in the baggage handling areas and the loft public areas.

Shops and catering units, offices, store rooms and back of house areas use 6000PLUS detector heads for fire detection and alert indication. The sensor included may check for smoke, heat or carbon monoxide; the sensitivity pattern can be matched and adjusted at the panel to virtually eliminate false alarms.

 

SUMMARY

In total, 61 Protec Algo-Tec digital addressable panels were used to provide the new fire detection and alarm system at the airport, with 53 acting as loop nodes and eight being used for display. The panels manage and control over 10,000 6000PLUS multi-sensor detector/alert head units, 2,300 interfaces, and 500 manual call points.

Other interfaces link the fire detection and alarm system to the travelators, doors, escalators and lifts, air handling plant, sprinkler system, and smoke extractors, to close or shut them down in case of a fire.

The order for Dublin airport was won against fierce competition from other companies. John Elam, Major Projects Director, commented, “One of the decisive factors to appoint Protec as fire safety provider was the impressive demonstration of the cloud chamber technology used in the Cirrus air sampling detectors that reduced the false alarm potential plaguing T1’s existing baggage handling area, as this is a very difficult environment to protect. This allowed the airport authority to prioritise increased efficiency for the new terminal, and with increased efficiency, look toward less time wasted and more satisfied passengers as the goal.”
