FOR SINGLE PANEL PROJECT, OMIT REFERENCE TO ICU’s THROUGHOUT SYSTEM DESCRIPTION (MFACP TERMINOLOGY IS APPLICABLE TO A SINGLE PANEL OR MULTIPLE PANEL BUILDING).
INSERT APPROPRIATE SECTION NUMBER IN PARAGRAPH BELOW.
A. The Facility Monitoring and Control Multiplex System (FMCMS), Section , monitors and controls each Protected Premises Fire Alarm System, and equipment located throughout the facility.
B. Each building system operates as a multiplexed protected premises fire alarm/emergency communication monitoring and control system.
USE FIVE SUBPARAGRAPHS BELOW FOR MULTI-PANEL BUILDINGS.
1. In Buildings 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 (NFPA 72 1-5.6).
a. The network micro-processors continually monitor the communications and data processing cycles of the building 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 SUBPARAGRAPH BELOW FOR SINGLE PANEL BUILDINGS.
2. In Buildings 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 microprocessor. Upon MFACP failure, an audible and visible alarm activates at the MFACP.
3. Upon MFACP failure a building (common) trouble condition is also indicated at the FMCMS.
4. 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 72 3-184.108.40.206.1.
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.
5. Smoke sensors act as intelligent and addressable devices. The smoke sensor converts the condition of it’s 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 which 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:
1) Frequent routine individual sensor alarm simulation testing.
2) Trouble signal when sensor is outside its acceptable sensitivity range.
6. System individually identifies each addressable initiating device and other addressable monitor functions using multiplexing techniques.
7. System is capable of individually operating each alarm notification appliance, and other control functions, using multiplexing techniques.
8. 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 which do not require interaction by the attendant are the third level of priority.
9. 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.
10. 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.
11. System visible and audible trouble signals and supervisory signals and visible indication of their restoration is indicated at the MFACP.
OMIT SUBPARAGRAPH BELOW IF NOT APPLICABLE.
a. Each ICU’s visible and audible trouble signals and visible indication of their restoration is indicated at the ICU.
b. Monitoring of ground fault conditions indicate a ground fault trouble condition at the MFACP.
c. Ground fault trouble condition also indicates building (common) trouble condition at the FMCMS.
12. Trouble conditions are sent to the FMCMS via transponders located in the FMCMS Equipment Cabinet (FEC).
a. Each building MFACP transmits one (common) system trouble condition to the FMCMS. Facility personnel will check the building’s MFACP to determine the specific system trouble condition(s) within the building.
13. Access to the system functions are controlled thru at least 3 levels of access security to prevent program modifications or use by unauthorized personnel:
a. At the lowest level of access the system automatically receives, displays and prints alarms, and performs control-by-event life safety functions. The attendant has minimum access to the system functions:
1) Alarm acknowledge.
2) Silence alarms.
3) Perform other basic system functions that require interaction by the attendant (cannot change program parameters).
b. At mid-level of access, the attendant may change user programmable parameters and print all summaries.
c. At the highest level of access, programs may be modified by the system manager (life safety control-by-event programs may be field or factory modified).
d. System access functions (log on, log off, access level authority) are displayed with date, time, and persons name.
14. Summary reports are displayed at the MFACP upon appropriate function command. Active control points are identified by an assigned message. Spare control points are identified by a point number. The summary reports can be interrupted and terminated and the system returned to normal operation by a manual reset control or automatically if the system senses a change of status signal.

IN SUBPARAGRAPHS BELOW REMOVE THE WORD “HOISTWAY” UNLESS IT COMPLIES WITH EXCEPTION NO. 1 (WHERE THE TOP OF THE ELEVATOR HOISTWAY IS PROTECTED BY AUTOMATIC SPRINKLERS), OR EXCEPTION NO. 2 (WHERE A SMOKE DETECTOR IS INSTALLED TO ACTIVATE THE ELEVATOR HOISTWAY SMOKE RELIEF EQUIPMENT).
23. Phase I automatic elevator recall for fire fighter’s service operates upon actuation of an elevator lobby smoke detecting device (excluding the designated floor lobby smoke detecting device) or actuation of an associated hoistway or machine room smoke detecting device. All elevators that service that lobby return non-stop to the designated floor. (If the smoke detecting device at the designated floor is activated, the elevators that serve that level return non-stop to the alternate floor).
a. Each elevator lobby, hoistway and machine room smoke detecting device is capable of initiating elevator recall when all other devices on the same initiating device circuit have been manually or automatically placed in the alarm condition.
b. The elevator automatic (smoke detecting devices) and manual (two and three position key switches) Phase I Emergency Recall Operation and the Phase II Emergency In-Car Operation operate in accordance with the applicable ANSI/ASME A17.1 Rules 211.3 thru 211.8 and NFPA 72 3-9.3.
c. For each group of elevators, three separate elevator control circuits terminate at the designated elevator controller within the group’s elevator machine room.
d. The smoke detecting devices actuate the three elevator control circuits as follows:
1) The smoke detecting devices located in the designated elevator recall lobby actuates the first elevator control circuit. In addition, where the elevator is equipped with front and rear doors, the smoke detecting devices in both lobbies at the designated level actuate the first elevator control circuit.
a) The first control circuit prevents recalling the elevators and discharging passengers to the designated floor when the designated floor is the fire location, and to provide for an alternate recall location when the designated floor is reporting a fire condition;
2) The smoke detecting devices in the remaining elevator lobbies actuate the second elevator control circuit.
a) The second control circuit provides standard recall to the designated floor when any other elevator lobby, machine room or hoistway smoke detecting device is in alarm;
3) The smoke detecting devices in elevator hoistways and the elevator machine room(s) actuate the third elevator control circuit. In addition, where the elevator machine room is located at the designated level, that elevator machine room smoke detecting device also actuates the first elevator control circuit.
a) The third control circuit is for the safety of the fire fighters who may be using the elevators to bring equipment to staging areas. This circuit also overrides the fire fighter’s key operation and brings the elevators to a safe level of discharge prior to equipment shutdown due to fire in hoistway or machine room. The circuit also sounds a warning in the elevator cab notifying the fire fighters using the elevator to immediately move to a safe floor and exit the elevators;
TWO SUBPARAGRAPHS BELOW ARE REQUIRED BY NFPA 72 22.214.171.124. OMIT THE WORD “HOISTWAY” IN THE NEXT 2 SUBPARAGRAPHS UNLESS IT COMPLIES WITH NFPA 72 3-9.3.4.
24. Each elevator lobby, hoistway, and machine room smoke detecting device, when actuated, initiates a system alarm condition. The alarmed zone, or addressable device is visibly annunciated at the MFACP and the ICU’s associated with the elevators.
a. Additionally, the hoistway and machine room smoke detecting devices visibly annunciate at the MFACP and ICU’s separately and distinctly from other visible annunciation, to alert fire fighters and other emergency personnel that the elevators are no longer safe to use due to smoke and fire intrusion into the hoistways and machine rooms.

2. HEAT DETECTOR OPERATES SOLENOID VALVE TO ALLOW WATER TO FLOW INTO THE SYSTEM. THIS METHOD USUALLY OPERATES THROUGH A CONTROL PANEL FOR MONITORING, ALARM AND TRIPPING FUNCTIONS.
a. Dedicated elevator shutdown ICU’s located in each elevator machine room, in conjunction with heat detecting devices located within two feet of each sprinkler head monitors the hoistways and machine rooms for heat/fire conditions.
1) The heat detecting device has both a lower temperature rating and a higher sensitivity as compared to the sprinkler, to ensure heat detecting device response prior to sprinkler head operation.
2) The elevator shutdown ICU’s and heat detecting devices are independent of the sprinkler system.
b. Smoke detecting devices located in each hoistway and elevator machine room monitor the hoistways and machine rooms for smoke/fire conditions. The smoke detecting devices are connected to system ICU’s. The smoke detecting devices are not connected to the elevator shutdown ICU’s. Sequence of Events:
1) Smoke in a machine room or hoistway during the initial stages of a fire activate the system smoke detecting devices, causing the system to perform the elevator recall functions.
2) As the intensity of the fire builds, the elevator shutdown heat detecting devices actuate, causing the elevator shutdown ICU to shunt trip the circuit breaker serving the main power line to affected elevators prior to the application of water. The sprinkler system operates independently after the affected elevator has shutdown.
3) Activation of elevator machine room or hoistway heat detecting devices are indicated by an audible alarm and a visual indicator in the MFACP.
