1.04 SYSTEM DESCRIPTION FOR SINGLE PANEL PROJECT, OMIT REFERENCE TO ICU’s THROUGHOUT SYSTEM DESCRIPTION (MFACP TERMINOLOGY IS APPLICABLE TO A SINGLE PANEL OR MULTIPLE PANEL BUILDING).
A. The system operates as a multiplexed protected premises fire alarm monitoring and control system.
USE FIVE SUBPARAGRAPHS BELOW FOR MULTI-PANEL BUILDING.
1. In Building With More Than One Fire Alarm Control Panel: Changes in the status of monitored points are indicated at the microprocessor based main fire alarm control panel (MFACP), utilizing distributed processing, peer-to-peer networked, interconnected control unit’s (ICU’s) located throughout the building.
SHOW EMERGENCY LIGHTING AT MFACP. SHOW A SMOKE DETECTING DEVICE IN EACH AREA WHERE FIRE ALARM PANELS ARE INSTALLED (NFPA72 1-5.6).
a. The network micro-processors continually monitor the communications and data processing cycles of the system.
1) A communications failure indication (print-out, display and audible alarm) occurs at the MFACP upon failure of the network communication and data processing cycle.
b. Upon MFACP failure, an audible and visible alarm activates.
1) Complete failure of the MFACP does not interfere with the ability of each ICU to perform its functions.
USE TWO SUBPARAGRAPHS BELOW FOR SINGLE PANEL BUILDING.
2. In Building With One Fire Alarm Control Panel: Changes in the status of monitored points are indicated at the microprocessor based main fire alarm control panel (MFACP).
a. The MFACP continually monitors the communications and data processing cycles of the micro-processor. Upon MFACP failure, an audible and visible alarm activates at the MFACP.
3. Smoke detectors and smoke sensors operate in conjunction with the systems’ alarm verification program.
IN AREAS WHERE ALARM VERIFICATION FEATURE IS DESIRED FOR ADDITIONAL PROTECTION AGAINST FALSE ALARMS OR UNWARRANTED DISCHARGE OF FIRE SUPPRESSION SYSTEMS, ALARM VERIFICATION ZONES FOR SMOKE DETECTORS, OR INDIVIDUAL SMOKE SENSORS OPERATING IN VERIFICATION MODE MUST BE INDICATED ON THE DRAWINGS. REFER TO NFPA 3-126.96.36.199.1.
a. The alarm verification operation is selectable by zone for smoke detectors and by individual devices for smoke sensors.
b. The activation of any smoke detector within its zone initiates the alarm verification program.
1) The panel resets the activated detector and waits for a second alarm activation. If within one minute a second alarm is reported from any detector within the zone, the system alarms. If no second alarm within one minute, the system resumes normal operation.
c. The system can display the number of times (tally) a smoke detector zone or smoke sensor has gone into a verification mode. A trouble condition occurs when the tally reaches a pre-programmed number.
4. Smoke sensors act as intelligent and addressable devices. The smoke sensor converts the condition of its smoke sensing chamber to an analog value. This analog value is digitized and transmitted to the FACP(s).
a. Actual smoke density and temperature measurements are referenced from average sample measurements and are compared to programmable values of threshold sensitivity.
b. Sensor “dirty” and “excessively dirty” trouble conditions are reported automatically through a maintenance advisory and alert program procedure.
c. The system continuously performs an automatic self-test routine on each sensor that checks sensor electronics to ensure the accuracy of the values being transmitted to the FACP(s). Sensors that fail are identified and indicate a trouble condition.
d. System automatically performs NFPA 72 sensor sensitivity testing by:
2) Trouble signal when sensor is outside its acceptable sensitivity range.
5. System individually identifies each addressable initiating device and other addressable monitor functions using multiplexing techniques.
6. System is capable of individually operating each alarm notification appliance, and other control functions, using multiplexing techniques.
7. Alarms are processed by the system at 3 levels of priority:
a. Fire alarms, supervisory, and trouble signals take precedence in that respective order of priority, over all other signals.
b. Other alarms that require interaction by the attendant have the second level of priority.
c. Monitored points that do not require interaction by the attendant are the third level of priority.
OMIT REFERENCE TO PRINTING IN THE NEXT SEVERAL SUBPARAGRAPHS IF PRINTER IS NOT DESIRED.
8. Alarms, supervisory signals, and trouble signals are distinctively and descriptively annunciated.
a. Fire alarm signals are distinctive in sound from other signals, and this sound is not used for any other purpose.
b. Supervisory signals are distinctive in sound from other signals.
1) System differentiates between supervisory device activation and trouble (wiring faults) on independent supervisory service initiating circuits.
c. Trouble signals are indicated by distinctive audible signals. Exception: The same sound may be used for both supervisory signal and trouble signal if distinction is made between signals by visible annunciation.
9. Switches for silencing audible trouble and supervisory signals transfers the audible signal to an identified lamp or other visible indicator adjacent to the switches. The visible indication persists until the condition has been corrected. The audible signal sounds when the switch is in its silence position and no trouble or supervisory condition exists.
a. Trouble silencing switch does not prevent sounding of supervisory signal. Subsequent supervisory signals from other zones causes the supervisory signal to resound. A switch left in the silence position where there is no supervisory off-normal signal operates a visible signal silence indicator and causes the trouble signal to sound until the switch is returned to normal.
b. A silenced audible trouble signal resounds at programmable time intervals (every 24 hours or less) as a reminder that the trouble condition has not been corrected. Re-sounded signal is retransmitted to all locations required of the original trouble signal.
10. System visible and audible trouble signals and supervisory signals and visible indication of their restoration is indicated at the MFACP.
OMIT SUBPARAGRAPH BELOW FOR SINGLE PANEL PROJECT.
a. Each ICU’s visible and audible trouble signals and supervisory signals and visible indication of their restoration is indicated at the ICU.
