Flashcards in Chapter #20 Fire Protection Systems Deck (137)
Provide notification of an emergency condition to building occupants and in some cases the local emergency response organization.
Fire alarm systems
System component that receives input from automatic and manual fire alarm devices and may provide power to detection devices or communication devices.
Fire alarm control panel (FACP)
Either manually operated or automatic Automatic sense the products of combustion or other hazardous conditions. Send a signal to the FACP.
List six examples of local notification devices.
Bells. Horns. Recorded voice message. Strobe Light. Speakers. Buzzers.
Name the four categories that notification devices fall under.
Audible. Visual. Textual. Tactile. (all can be used in combination)
What items may be located in the Fire Command Center (FCS)?
Fire alarm control panel. Smoke control station. Fire pump status indicators. Emergency elevator controls. Emergency communication systems. Spare sprinklers and fuses. Building plans and system diagrams.
Alarm system that alerts and notifies only occupants on the premises of the existence of a fire so that they can safely exit the building and call the fire dept. If a response by police or fire is needed, an occupant must notify the wanted agency.
Protected premises system (local alarm system).
Name the three types of local alarm systems.
Noncoded. Zoned/annunciated. Addressable
The simplest type of local alarm. If one alarm goes off they all go off. Only practical in small buildings.
A general location/ zone of what device was activated is given.
Displays the location of each initiating device. Can pinpoint the specific location of the initiating device.
Addressable alarm system
Continuously monitors a remote location for the purpose of reporting a supervisory, trouble, or alarm signal to the appropriate authorities. Predominant type of signal monitoring in the US.
Supervising Station Alarm Systems
List the four types of supervising station systems.
Auxiliary alarm system. Central station system. Proprietary system. Remote receiving systems.
System that is connected to a municipal fire alarm system. Alarms are transmitted to the public fire telecommunication center and appropriate agency is dispatched. Two types: Local energy System & Shunt System.
Auxiliary alarm system.
Auxiliary fire alarm system that has its own power source. Served by the municipal fire alarm box system.
Local Energy System
Auxiliary fire alarm system that is directly connected to the municipal alarm system. Alarms are automatically initiated over the municipal system.
Used to protect large buildings or multiple buildings. Alarms go to a common receiving building that is staffed with personnel who can take appropriate action when a alarm is sounded. Owned and operated by the property owners.
Monitored by a contract service. (Alarm company)
Central Station System
System in which alarm signals from the protected premises are transmitted over a leased telephone line or by radio signal to a remote receiving station with a 24-hour staff; usually the fire depts alarm communication center.
Remote Receiving System
Identify the presence of fire or products of combustion and send a signal to the alarm system. Can be manual or automatic.
Alarm initiating device
A manual pull station is required to have what incorporated in its design?
It must be red with white lettering that species what the device is and how to use it.
Alarm initiating device that is designed to be responsive to a predetermined rate of temp or to predetermined temp level.
Name the two types of heat detectors.
Fixed temp. Rate of rise
What detectors have the least false activation's and are also the slowest to activate?
Fixed temp heat detectors.
What is the common set temp for a fixed temp detector in living spaces? For attics or other areas subject to elevated temps?
165 F. 200 F.
Name three types of fixed temp heat detectors mechanisms.
Expansion of heated material. Melting of heated material. Changes in resistance of heated material.
A fragile bulb contains liquid and a air bubble. When the liquid is heat what happens?
The air bubble is absorbed and the glass breaks.
What type of initiating device mechanism may still be in use but is no longer made.
Can detect heat over a linear area parallel to the detector.
Continuous line detector.
