Chapter 20 Fire Protection systems fully solved graded A+ passed Fire Protection systems functions - correct answer 1. notifying building occupants to take necessary action to escape in the event of a fire 2. detecting the presence of fire or products of combustion 3. summoning organized assistance to initiate or assist in fire control activities 4. initiating automatic fire control and suppression systems and sounding an alarm 5. supervising fire control and suppression systems to ensure that operational status is maintained 6. operating ventilation systems to remove smoke and other products of combustion 7. initiating a wide variety of auxiliary functions involving environmental utility and process controls including control of elevators Fire protection systems include - correct answer 1. alarm systems 2. alarm initiating devices 3. automatic sprinkler systems 4. standpipe and hose systems 5. smoke management systems 6. building controls used in a coordinated fire protection systems fire protection system - correct answer System designed to protect structure and minimize loss due to fire. Components that make up a typical alarm system - correct answer 1. fire alarm control panel 2. power supplies 3. initiating devices 4. notification appliances 5. Fire command center (if applicable) Fire alarm control panel - correct answer system component that recieves input from automatic and manual fire alarm devices and may provide power to detection devices or communication devices 1. contains the electronics that control and monitor the fire alarm system 2. serves as the brain for the alarm ssytem 3. recieves signals from alarm initiating devices processes the signals and produces putput signals 4. power and fire alarm circuits are connected directly into this panel 5. power boosters and power supplies for the notification system are considered to be part of the FACP 6. controls for the alarm system are located in the FAC{ 7. the FACP can also perform other functions such as the control of a remote annunciator panel the operation of relays that capture and recall elevators or publi address and mass notifications annunciator panel - correct answer Electrical device used to indicate the source or location of an activated fire alarm initiating device or the status of the system. The panel may include individual lights located on a schematic map and an audible alarm signal. Power supplies - correct answer primary and secondary power supply primary- power supply is usually obtained from the buidlings main connection ot the local utility provider. if the primary power supply is interrupted due to a loss of pwoer an alarm signal must be activated secondary- batteries with charges and auxillary generators Initiating devices - correct answer manually operated pull stations or automatic (smoke detectors) these devices send a signal to the FACP and may either be hard wired or connected over a special radio frequency notification appliances - correct answer once an initiating device sends a signal to the FACP the control unit processes the signal and activates local and rmeote notification appliances. the system may include the ability send a signal to a centrla alarm monitoring center or directly to the fire deparmtent local include 1. bells 2. horns 3. recorded voice messages 4. strobe lights 5. speakers 6. buzzers -audible is the most common -may only sound in the area of hte activated detector or sound in the entire facility Notification categories - correct answer 1. audible 2. visual approved lighting decives 3. textual- visual text or symbols indicating a fire or emergency condition 4. tactile- indication of a fire or emergency conditions through sense of touch or vibration Fire command center - correct answer Designated room or area in a structure where the status of the fire detection, alarm, and protection systems is displayed and the systems can be be manually controlled; may staffed or unstaffed and can be accessed by the fire department. fire control room or station 1. many large buildings now incoproate this 2. consolidates all of the fire protection system controls for the structure in one location 3. allows the various fire protection systems in the structure to be conviently monitored and controlled as needed items contained in the FCS 1.
