Definitions
Addressable system
- a fire alarm and detection system that contains addressable alarm zone
facilities or addressable control devices.
Alarm Verification Facility (AVF)
- that part of the FACP, which provides an automatic resetting
function for spurious alarm signals so that they will not inadvertently initiate Master Alarm Facility
(MAF), or ACF functions. Using ConfigManager prior to downloading to the
FireFinder
™ sets this
option
Alarm zone
- the specific portion of a building or complex identified by a particular alarm zone
facility.
Alarm Zone Circuit (AZC)
- the link or path that carries signals from an actuating device(s) to an
alarm zone facility(s).
Alarm Zone Facility (AZF)
- that part of the control and indicating equipment that registers and
indicates signals (alarm and fault) received from its alarm zone circuit. It also transmits appropriate
signals to other control and indicating facilities.
Alert signal
- an audible signal, or combination of audible and visible signals, from the occupant
warning system to alert wardens and other nominated personnel as necessary to commence
prescribed actions.
Ancillary Control Facility (ACF)
- that portion of the control and indicating equipment that on
receipt of a signal initiates predetermined actions in external ancillary devices.
Ancillary equipment
- remote equipment connected to FACP.
Ancillary relay
- relay within FACP to operate ancillary equipment.
Ancillary output
- output for driving ancillary equipment.
Approved and approval
- approved by, or the approval of, the Regulatory Authority concerned.
Card-detect link
- a link on a module connector to indicate the disconnection of the module.
Conventional System
- is a fire detection system using a dedicated circuit for each alarm zone.
Distributed system
- a fire alarm and detection system where sections of the control and indicating
equipment are remotely located from the FACP or where sub-indicator panel(s) communicate with a
main FACP.
Field connections
- are connections made to FACP or ancillary equipment during installation.
Fire alarm system
- an arrangement of components and apparatus for giving an audible, visible, or
other perceptible alarm of fire, and which may also initiate other action.
Fire detection system
- an arrangement of detectors and control and indicating equipment
employed for automatically detecting fire and initiating other action as arranged.
Fire Alarm Control Panel (FACP)
- a panel on which is mounted an indicator or indicators together
with associated equipment for the fire alarm or sprinkler system.
Fire resisting
- an element of construction, component or structure which, by requirement of the
Regulatory Authority, has a specified fire resistance.
Indicating equipment
- the part of a fire detection and or alarm system, which provides indication of
any warning signals (alarm and fault), received by the control equipment.
Interface
- The interconnection between equipment that permits the transfer of data.
Main equipment
- equipment essential to the operation of the system including, control equipment,
amplification equipment and power supply modules.
Master Alarm Facility (MAF)
- that part of the equipment which receives alarm and fault signals
from any alarm zone facility and initiates the common signal (alarm and/or fault) for transmission to
the fire control station. Bells and other ancillary functions may be initiated from this facility.
Power Supply
- that portion of the FACP which supplies all voltages necessary for its operation.
Regulatory Authority
- an authority administering Acts of Parliament or Regulations under such
Acts.
