| Term | Definition |
|---|
| NFPA 72, | The comprehensive installation standard |
| NFPA 70 | National electrical code |
| Annunciator Panel | Displays information about the location and type of alarm |
| All annunciators include | Floor: the level where the signal originated, Zone: the area where the signal originated, Device: the type of alarm or supervisory initiating device. |
| Alarm Devices | They indicate a situation requiring emergency action and normally activate evacuation signals. |
| Annunciator Graphic Diagram | They enable firefighters to determine where to investigate alarms originating in locations with designations |
| Voice Alarm Systems | Automatically send a voice evacuation message to speakers in selected areas of high-rises or expansive buildings, hospitals, and other buildings where total evacuation is impractical |
| Fire Department Communications Systems | 2-way telephone systems typically required in highrise buildings. |
| Fire Command Centers | Buildings that have a dedicated room or other location containing fire alarm and related fire protection control equipment |
| Flow switches or pressure switches | Indicate water flow |
| Alarm devices indicate? | A situation requiring emergency action and normally activate evacuation signals |
| Supervisory devices signal? | A need for non-emergency action, such as repair, and they should not cause an evacuation alarm or notify the fire department |
| Status Indicators | Give information about whether the main fire alarm power is on, or they report on the condition of devices external to the alarm system |
| Graphic Displays | Diagrams enable firefighters to determine where to investigate alarms originating in locations with designations |
| Controls in Fire Alarm Systems are? | switches that control features external to the fire alarm system |
| Emergency Power System | A fixed, emergency power system built into the building, separate from regular power systems |
| Cascade Systems in large buildings should be placed at | Outside enclosed, fire-rated stairs |
| Firefighter breathing air system consists of | a piping distribution system that runs from a supply point to interior "fill stations" or "fill panels |
| Fill stations | Large enclosures in which cylinders are replenished within a blast fragmentation container using rigid fill connections |
| Radio Signal Retransmission Systems | Technology that allows communication inside of buildings where Radios and Cellphones do not |
| Smoke Control Systems | Mechanical systems that control the movement of smoke during a fire |
| Manual Smoke Control Systems Controls | Override automatic controls that activate these systems |
| Most Common Smoke Control Systems | Atrium smoke exhaust systems and stair-pressurization systems |
| Radio Signal Retransmission Systems Ordinances require? | Signal strength, area coverage, reliability, secondary power supply, interference filters, acceptance testing upon completion, and ongoing periodic testing. |
| Passive Antenna System | Includes both an internal and an external antenna, connected with a short coaxial cable |
| Active Signal Transmission Method | Powered devices amplify signals between an external antenna and one or more internal antennae |
| BDA | Bi-Directional Amplifier |
| Emergency System Receptacles are located | Inside in closed stairwells |
| Many Emergency System Receptacles are labeled? | For Fire Department Use Only. |
| Firefighter Breathing Air Systems must specify system performance as? | Minimum number of cylinders to be simultaneously filled, maximum cylinder pressure, maximum fill time. |
