Introduction
    Intelligent Addressable Systems

• An intelligent addressable fire alarm system...
   …provides a level of protection that far exceeds what was
    ever possible with any conventional system
   ...offers the flexibility to comply with a wide range of
      code requirements
   …satisfies a growing number of application needs

• This course is intended to familiarize you with
  the benefits of an intelligent addressable fire
  alarm system
             We Will Address

• When is it absolutely necessary to install
  an intelligent addressable system

• When is it highly desirable to install an
  intelligent addressable system
Generations of Fire Alarm Systems
  Generations of Fire Alarm Systems

• Conventional system
  • Not always the low cost solution

• Addressable system
  • A good intermediate step

• Intelligent addressable system
  • An ideal solution
          Conventional Systems

• One-way communication
  • Uses voltage change for the
    communication signal
  • “Short” = Alarm
  • “Open” = Trouble
• Zone only identification
  • General (non-specific) location
            Addressable Systems

• Two-way communication
• Device address is identified and
  communicated to panel
• Panel polls the device
   • Device in alarm or non-alarm condition
   • Can signal alarm, trouble, or maintenance
     requirement
• Pinpoints hazard via display at control panel
• Programmable input-to-output activation
             Analog Systems

• According to the National Fire Alarm Code
  Handbook, an analog system uses
  devices which transmit signals indicating
  varying degrees of condition, as opposed
  to just alarm and trouble

• This is only a portion of a true intelligent
  addressable system
    Intelligent Addressable Systems
• Two-way communication
• Device address and “vital signs” are identified
  and communicated to panel
   • Device status (alarm/trouble)
   • Smoke levels (normal/pre-alarm/alarm)
   • Compensation for dust accumulation (specific
     sensitivity levels)
   • Integrity of the device’s electronics
• Programmable input-to-output activation
• Control panel compiles the information and
  decides specific action
Intelligent Addressable Fire Alarm
        System Components
Intelligent Addressable Controls
   Intelligent Addressable Controls

• Utilize “Signaling Line Circuit” (SLC) Loop
  wiring, connecting all addressable input
  and output devices to the addressable
  control along the same pair of wires

• Conversely conventional systems use IDC
  and NAC wiring, which requires individual
  cable runs for each function
Typical SLC Arrangement
   Intelligent Addressable Controls

• Each protection point (e.g., detector, pull
  station, etc.) has a unique number
  assigned to it called the address for
  reporting alarms and troubles
  • Allows the control to distinguish one
    addressable device from another
  • Displays the address when an event occurs on
    that device
   Intelligent Addressable Controls

• These controls interrogate each
  intelligent device via the SLC or multiplex
  loop

• Each device answers the control and then
  a decision is made on what, if anything,
  needs to be done
   Intelligent Addressable Controls

• These controls can also monitor
  conventional initiating devices using
  addressable monitor modules
• For example, conventional notification
  appliances are activated by addressable
  control modules
• Serial annunciation and printer options
  are generally available for these units
   Intelligent Addressable Controls

• System is programmed to activate certain
  output devices based on alarm activity
  from certain input devices

• The process of linking outputs to inputs in
  programming is Software Zoning
        Control Panel User Interface

• End-user friendly
• LCD display and alpha-numeric keypad
  • LED indicators
    •   Fire alarm       •   Maintenance
    •   System trouble   •   Disabled point or zone
    •   AC power on      •   Battery
    •   Supervisory      •   Ground
    •   Alarm silenced
         Remote User Interface

• Liquid crystal display annunciator
• Duplicates the alpha-numeric information
  displayed at the panel in multiple remote
  locations
         System Communication

• EIA-232 for connection to PC for programming
  or connection to a serial printer
• Dedicated EIA-485 port for connection to LED-
  type annunciators and digital communicators
• Dedicated EIA-485 port (4 data wires & 2 wires
  for 24 VDC) for connection to alphanumeric
  annunciators
         Communication Devices

• Point I.D. digital
  communicators
  • Report status information
    from every intelligent device
    in a system (e.g., detectors,
    modules, annunciators, etc.)
        Communication Devices

• Annunciator relay modules
  • Provide fully supervised
    control of ancillary systems
    (e.g., elevator recall, HVAC
    shutdown, etc.)
Intelligent Addressable
  Software Features
         Intelligent Addressable
         Software Programming

• Software allows you to assign activation
  of specific output devices in response to
  the initiation of specific input devices
      Operating System Software

Voice Evacuation
       Voice Evacuation Systems

• For emergency notification
  • Use speakers located
    throughout a facility
  • Communicate specific
    instructions to building
    occupants
Why Use a Voice Evacuation System?

• Emergencies can be confusing and disorienting
  for building occupants
• It is further complicated when in unfamiliar
  surroundings (e.g., hotels, auditoriums, etc.)
• Horns, sounders and strobes do not clearly
  indicate specific evacuation instructions
• Research shows that the integration of a voice
  capability into a fire alarm system provides the
  best method for effective evacuation
Why Use a Voice Evacuation System?

• Life safety is the primary purpose of any voice
  evacuation system, normally working in
  conjunction with the fire detection system

• Voice evacuation systems are generally used to
  guide building occupants to safer location rather
  than causing a general evacuation, though they
  can be used for both
       When is a Voice Evacuation
          System Required?

• National Codes direct the installation
  of a voice evacuation system in
  places of assembly greater than 300
  people, in multiple-screen theaters
  and high rise buildings

• Local authorities often extend this
  requirement to facilities with 50 or
  more occupants
        How are Voice Evacuation
          Systems Employed?

• Voice evacuation systems can be integral to an
  intelligent addressable fire alarm system or as a
  free standing unit
• The voice evacuation system may be connected
  to a fire alarm command center from which pre-
  recorded or “live” messages can be issued to
  individual zones or the entire building
• Some systems have warden stations or jacks on
  each floor from which a fire warden or fire
  officer can issue evacuation instructions
