addressable advantages • System components • Pursuing applications 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 • Non-volatile memory (retained after loss of all operating power) • Three levels of user interaction • Read Status • No password required • Programming – Maintenance Mode • User programmable password • Programming – Master Mode • Alarm company programmable password Operating System Capabilities • Silence inhibit timer (60 sec. duration) • Alarm verification per intelligent detector • Waterflow selection per monitor module • Pre-signal delay for manual pull stations • Onboard NAC synchronization • Saves time and money over wiring individual sync modules • Allows the entire system to notify in sync • Allows you to meet or exceed code requirements Operating System Maintenance and Troubleshooting • Automatic device type code verification • Continual automatic detector testing • Detector sensitivity printout • Drift compensation Intelligent Addressable System Devices Intelligent Detectors • Photoelectric • Photoelectric with heat • Ionization • Duct • Duct with relay • Heat • Heat rate-of-rise Intelligent Detectors • Automatically adjust sensitivity levels without the need for operator intervention or programming • Easy-to-use rotary switches for setting addresses (01-159) • Example: to set address 119… • …set the tens switch to “11” • …set the ones switch to “9” Intelligent Detectors • Multi-criteria designs • Sensitivity increases with heat • Combination photo and thermal technologies • Peak/off-peak setting • Pre-alarm levels • Alarm verification Addressable Modules • The interface between conventional devices and the intelligent SLC circuit • Retrofit applications • Connecting to other systems Addressable Input Modules • Monitor module • For monitoring a circuit of normally- open contact conventional alarm initiating devices • Monitor module • For monitoring 2-wire smoke detectors • Dual monitor module • For monitoring normally-open contact alarm initiating devices Addressable Input Modules • Mini-monitor module • For monitoring a single conventional, contact- type device in the same mounting box Addressable Input Modules • Addressable pull station • Single or dual action Addressable Output Modules • Notification appliances don’t have built-in transmit/receive circuitry • Addressing is accomplished by wiring the NAC circuit to an output module Addressable Output Modules • NAC control module • NFPA Style Y (Class B)/Style Z (Class A) notification appliance circuit • Programmable for the following: • Auto-silence (timed sounder cutoff) • Silence inhibit • Silenceable vs. non-silenceable - enable/disable Addressable Output Modules • Relay control module • Elevator recall • Damper control • Door holding • Auxiliary control functions 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 Intelligent Addressable System Advantages
