FIRE DEPARTMENT OPERATION

FIRE DEPARTMENT ACCESS:-

Briefly, the road networks serving the Complex allows the Civil Defence to undertake fire-fighting and search and rescue operations.

As such, it is essential to provide emergency vehicular access in accordance with Qatar Civil Defence (QCDD) regulations and NFPA requirements.

The QCDD regulations take precedence and reference is made to the NFPA5000

and NFPA 101 where there is insufficient detail in the QCDD regulations. The requirement of the International Fire Code, 2009 edition, has been considered to this complex. The NFPA Codes leave certain elements to the discretion of the QCDD due to their operational responsibilities.

EXTERIOR ACCESS :

The QCDD regulations require fire service access from a t least t w o s i d e s o f the C o m p l e x in addition to the main entrance of theComplex.Additionally,NFPA5000 requires that any portion of the facility, or any portion of an exterior wall of the building ground floor perimeter, is locatedwithin137 meters from fire service access roads for sprinklered buildings. This has been complied with.The fire service access to the Complex is illustrated as highlighted in the Planof Master Ground Plan Layout.

FIRE FIGHTERS' EMERGENCY LIFT

In the event of a fire alarm being raised for one building block, all lift swill automatically descends to the designated evacuation level (i.e. Street level) and remain parked until they are allowed to return to normal service. The lifts are equipped with fire fighters emergency operation facilities in accordance AS.ME A17 .1 safety Code for Elevators and Escalators. On the activation of the lift recall system, the lifts will return to ground floor (designated floor).The fire lifts shall remain at ground floor for use by QCDD. The lift shafts have been fire separated from the remainder of the building with 2-hours fire resistance level.

SEQUENCE OF OPERATIONS ACTIVATED BYTHE FIRE ALARM PANELOPERATION of VOICE EVACUATION SYSTEM

All evacuation will be controlled through Voice Alarm System Rooms located next to the Fire Alarm Panels. In case of fire, Remote Call-stations will initiate the pre-defined fire announcement through wall mounted and ceiling mounted Loudspeakers.

OPERATION OF FIRE FIGHTING SYSTEMSSprinkler System

Bursting of any sprinkler bulb by heat according to temperature limitations explained in Sprinkler System description causes the water to be discharged through that sprinkler.This water flow causes two (2) actions:

It is sensed by the flow switch on the sprinkler piping and a signal is sent to the fire alarm panel.

The water pressure in the wet fire standby piping drops and this activates the fire pumps.

Fire Alarm Panel Reaction to Sprinkler Bursting

This signal by the flow switch is displayed on the fire alarm panel with audible alarm indicating the zone of the signal.The panel immediately activates the below described pre determined sequence of operations for each zone depending on the location of signal without waiting for acknowledgement or fire investigation period.If the sprinkler loop branch cut-off valve is closed for any reason, this is monitored and alarmed from the fire alarm panel through a tamper switch on the valve

Fire Hose System

The Fire Hose will be used by the responsible personnel in case of fire. The hose reel turns on automatically when 1.5 to 1.8 meters of hose is withdrawn from the real/drum.

FM200 Automatic Fire Suppression System

Activation of any one of the detector in any circuit within the affected area illuminates the "Alarm" indicator on the control panel and energize alarm bell inside Hazard Area (1st Stage Alarm). Subsequent operation of a "cross-zoned" detector within the affected area illuminates the "Pre-Discharge" indicator on the control panel and activates the strobe/horn inside the hazard area (2nd Stage Alarm). Fire dampers are closed and HVAC equipment is shut down (if connected) wherever applicable. Circuit is actuated to energize 0-30 seconds adjustable "Evacuation Timer"... System abort sequence is enabled and magnetic door releases are deactivated After completion of the pre-set time .delay sequence; circuit is actuated to release HFC- 227 EA agent into affected area, "RELEASE" indicator on the control panel is illuminated, visual indicator outside the hazard in which the discharge occurred along with alarm/horn is energized and circuits are actuated to deactivate electrical supply to all computer equipment in affected area via shunt trip breaker.

System is also provided with a manual actuator to release the gas manually without involving control panel.

Manual Fire Extinguishing System &Fire Blankets

In the kitchen areas of the apartment buildings, there will be manual Fire Extinguishers (C02) and Fire Blankets to protect the residents against heat, smoke and fire in case of a fire condition.

Fire Fighting Pumps (One electrical, One Diesel and One Jockey)

In case of bursting of any sprinkler within the Fire Fighting system, the water

pressure in the wet fire standby piping drops. Following this drop in the system, Duty Fire Pump (Fire Electrical Pump) is activated and immediately starts running. Fire Electrical Pumps continue to run in all cases until the Fire situation is cleared and fire alarm is reset, Standby Fire Pump (Fire Diesel Pump) has a pressure switch which is set to start the engine when the system pressure drops 10 to 15 PSI below the electric driven main pump. The Engine has a dedicated fuel tank with sufficient capacity to run the engine for at least 3 hours of operation.

Under normal conditions (no sprinkler bursting), in case water. leakage within the fire fighting piping system occurs, Jockey Pump starts running in order to balance the water pressure within the system.
