Building Zones

In January 2015 a new zoned alarm system was activated. The building has been divided into SIX independent fire zones with self closing fire doors and warning beacons. The fire alarm is a speaker system that can broadcast pre-recorded messages or act as a zone or whole building public address system.

The six alarm zones are:

  1. (EZ1) IS Infrastructure - Floor 1 and 2 of IS block accessed from east entrance (opposite Swann Building).
  2. (EZ2) South East Wing - Corridors 14 to 54 and also 15 and 25.
  3. (EZ3) Centre South Wing - Corridors 16 to 56.
  4. (EZ4) South West Wing - CSEC, Floors 1 to 3 of Erskine Williamson Building.
  5. (EZ5) Lecture Theatre Block - Lecture Theatres A/B/C, study spaces in 39 corridor and office/store rooms in 29 area.
  6. (EZ6) Main Building - all locations off main east/west corridors from Floors 1 to 8.

The boundaries between each zone are designated by a red beacon and sign that says "Fire Alarm Activated, Do Not Enter". Also the fire door on the boundaries have additional fire proof glass panels.

See Zone Plan for details.

For greater details see the talk on the new alarm system prepared by the Fire Safety Unit.

Alarm Activation

The alarm is activated by three types of detector, these being

  • Smoke detectors in all rooms and corridors throughout the building.
  • Heat detectors in various high risk areas such as plant room, workshops and kitchens.
  • Manual break glass alarm call points in corridors and stairwells.

The alarm activation sequence is:

  • Single smoke detector activation will trigger the alarm in the LOCAL ZONE ONLY; second smoke detector activation anywhere in the building will trigger the alarm in ALL ZONES.
  • Any heat detector activation will trigger the alarm in ALL ZONES.
  • Any manual break glass alarm call point activation will trigger the alarm in ALL ZONES.

When the alarm is triggered in a zone:

  • Pre-recorded announcement from all speakers in the zone that the alarm is activated to evacuate the zone.
  • All magnetically held open fire doors in that zone will close and any swipe card entry door will de-activate.
  • Warning speakers and beacons at the entry to the zone will activate.
  • Lift in that zone will ground.

If the alarm triggers in ALL ZONES, then each zone will activate as above.

Evacuation Procedure

All Zones Triggered

Evacuate the whole building using all available fire exits (following the green fire exit signs), appropriate speaker message will be broadcast in each of the zones. All lifts will ground. Do-not enter the building until given the all-clear by Fire Officers or University Security.

Note that during an ALL Zones alarm the red flashing beacons between zones will NOT be activated so if the closest fire exit is via another zone, this exit should be used.

Single Zone Triggered

Evacuate the single zone using all available fire exits, speaker message will only be broadcast in this single zone and warning beacons at the zone boundaries will be flashing. Lifts in triggered zone will ground. Other zones will NOT be affected in any wayDo not re-enter zone until alarm has been switched off and the all clear given.

It is intended that for single zone evacuation that people SHOULD exit the building, but for the smaller zones, they may move into the main building, for example the 5th floor Common Room or the Magnet Cafe. It is important however in the main building or lecture theatre zones that large numbers do not over-crowd the other zones. Here, the largest potential problem is the lecture theatre block exiting back into the main building 3rd floor foyer.

Staff located in a different zone are free to evacuate the building if they are at all concerned.
