Fire detection and alarm system

World Trade Center Amsterdam has an inter-connected fire detection and fire alarm system. It is designed to detect and contain fires and is monitored 24 hours a day at the WTC Security Control Room. This system is equipped with smoke detectors and sprinklers in key areas, as well as manual fire alarms and magnetic-lock doors. 

Standard operating procedure WTC Security and Fire Department
When a fire detection device is activated, the WTC Security Control Room and the fire department are notified immediately and simultaneously. A WTC Security Officer will be sent to the location of the activated fire alarm device to confirm the fire. At the same time the fire department will call the WTC Security Control Room to confirm that a fire alarm has been received. The standard procedure is as follows:

  • If a fire is confirmed by WTC Security, the fire department will be instructed to send a fire fighting unit immediately. If WTC Security does not respond to the fire department within two minutes, a fire fighting unit will be sent automatically
  • When a fire is confirmed, WTC Security will evacuate one or more towers manually. See section 5.2 for detailed information regarding the evacuation alarms system
  • WTC Security will assemble the WTC Emergency Team to assist with the evacuation process on the ground floor. This is only possible during office hours.
  • WTC Security and/or WTC Emergency Team will – if possible - assist the fire department with crowd control etc. 
  • After it is safe to return to the offices, or when a false alarm has been confirmed, WTC Security and/or WTC Emergency Team will inform tenants by using the public address system and other methods. During office hours, WTC Management will also post a notification on the home page of www.mywtcamsterdam.com

Fire alarm system general procedures 
Evacuation alarms can be activated automatically or manually depending on the regulations applicable in the different towers. See below for the general principles per tower.
 
Towers ABC 
If a smoke detector, manual fire alarm or sprinkler goes off in these towers there will be no automatic evacuation alarm, with the exception of Qbic Hotel. If necessary, the evacuation alarm will be manually activated by WTC Security on a tower-by-tower basis. 
 
Towers FG
If a manual fire alarm goes off in these towers an automatic evacuation alarm will be activated on all floors of the concerned tower. If a fire alarm or sprinkler goes in these towers there will be no automatic evacuation alarm. If necessary the evacuation alarm will be manually activated by WTC Security.
 
Platform offices including conference center
This concerns all spaces between towers ABC from level 1 to 4. If a smoke detector, manual fire alarm or sprinkler goes off in these spaces there will be no automatic evacuation alarm. If necessary, the evacuation alarm will be manually activated by WTC Security. 
 
Tower H - floors 1 to 27
If a smoke detector, manual fire alarm or sprinkler goes off in tower H, an automatic evacuation alarm will be activated on the affected floor including the floor above (+1) and the floor below (-1). This applies to the offices, lift area and toilets.
 
Attention! Because of the high sound level and the presence of emergency stairs and elevator shafts, the fire alarm - to some degree – will also be audible in the lift lobbies of nearby floors. If the alarm is not produced by the speakers on your floor, but is audible ‘from a distance’ there is no need to evacuate.
 
Tower H - emergency stairs
If a smoke detector goes off on any level in the stairwell, an automatic evacuation alarm will be activated throughout the entire stairwell (level 1 to 27).
 
Tower I - floors 1 to 7
If a smoke detector, manual fire alarm or sprinkler goes off in tower I, an automatic evacuation alarm will be activated on the affected floor, the floor above (+1) and below (-1). In line with regulations, only the stairwell in Tower I on the Tower H side is fitted with evacuation loudspeakers. There is no evacuation alarm in the other stairwells. 
 
Attention! Because of the high sound level and the presence of emergency stairs and elevator shafts, the fire alarm - to some degree – will also be audible in the lift lobbies of nearby floors. If the alarm is not produced by the speakers on your floor, but is audible ‘from a distance’ there is no need to evacuate.
 
Exception level H3/I3
The office on floor H3 extends into I3 and so the alarm zones have been linked together. This means that if a smoke detector, manual fire alarm or sprinkler goes off on H3, an automatic evacuation alarm will be triggered on H3 and I3 (offices and lift area) and vice-versa.
 
Lobby H/I
If a smoke detector, manual fire alarm or sprinkler goes off on level H1 or I1, an automatic evacuation alarm will be triggered in Lobby H/I.
 
Car park - under towers ABCDFG
If a smoke detector or sprinkler goes off in this section of the car park, there will be no automatic evacuation alarm. If necessary, the evacuation alarm in this section will be activated by WTC security staff.  
 
Car park - under towers H/I, Zuidplein in in the bike park
If a smoke detector, manual fire alarm or sprinkler system is activated in the car park under H/I towers, under Zuidplein or in the bike park, the evacuation alarm will be triggered automatically throughout this entire zone. The evacuation alarm is also triggered automatically when a high level of CO2 or LPG is detected. In this case fire doors will close automatically and the entrance barrier of the parking will stay closed. All persons will have to leave the parking by using the fire escape routes. 
 
Test fire alarm
For safety reasons, the public address system is tested every last Monday of the month at 16.00. Please contact WTC Servicepoint at info@wtcservicepoint.com if the slow whoop or spoken instruction is not audible. To reduce nuisance, WTC Security will check the fire detection and fire alarm system periodically during the night.
 
General Safety Principles
When a fire alarm is activated: 

  • Locks on the doors of offices with an escape route inside the leased space will open automatically to allow other tenants on the same floor to exit
  • Elevators in the affected tower will be recalled to the lobby automatically
  • The smoke control system in the affected tower will activate automatically to pressurise the stairwells and keep smoke out
