Central Station

An entity controlled and operated by a person, firm or corporation whose business is the monitoring, recording, and maintaining of supervised alarms automatically transmitted to it by the FDAS of a subscriber of this service, and who upon receipt of each signals shall take such actions as required by the AHJ and the subscriber.

Conventional Device

An FDAS component, such as a smoke detector, heat detector, or manual fire alarm station, that does not have an electromechanical or software address that gives it a discrete identity.

Conventional System

A system with a conventional fire alarm control panel and conventional devices that is wired in a way that divides the protected building or premises into parts or subdivisions which are called alarm Zones

Detector

A device or component that is used to sense the products of fire, such as smoke, heat, flame, or carbon monoxide.

Smoke Detector

A detector that detects particles of combustion, whether visible or invisible.

Heat Detector

A detector that detects abnormally high temperature, abnormally

Multi-criteria Detector

A detector that contains two or more sensors that tracks the corresponding products of fire, such as smoke, heat, flame, or carbon monoxide, and transmits signals to the fire alarm control panel, which shall mathematically evaluate them with pre-programmed algorithms to determine when an alarm signal is warranted. The evaluation may also be performed at the detector. The objective of using this type of detector is to reduce false alarms. fast rate of temperature rise, or both.

Duct Detector

A smoke detector, using sampling tubes, that senses smoke in the air circulating within air-conditioning or ventilating ducts.

Beam Detector

A smoke detector that senses smoke along a continuous path usually installed in high-ceiling areas.

Air Sampling-type Detector

A detector that consists of a piping layout of network that runs from the detector to the protected area or areas.

Carbon monoxide Detector

A detector that senses and detects abnormally high levels of carbon monoxide.

Emergency Communications System

A sub-system of an FDAS that broadcasts the existence of a fire or an emergency situation, or communicates information necessary to facilitate an appropriate action.

Emergency Voice Alarm Communication (EVAC)

It is a sub-system that broadeasts information during an emergency to the occupants of a building or facility and instructs appropriate actions to them, such as evacuating. It is conveyed by audible or visible means or both.

Two-Way Emergency Communications System

It is 4 sub-system intended for use by the building fire safety personnel or by fire fighters and first responders to both exchange information and to communicate information, such a5 condition of local environment, condition of persons, to give assurance that help is on the way, or other instructions.

Fire Alarm Control Panel (FACP)

An FDAS component, provided with primary and secondary power supplies that receives signals from initiating devices, such as detectors and manual fire alarm stations, and processes these signals to determine the required output functions, such as activation of notification appliances, annunciators, and the one-way emergency communications system.

Conventional Fire Alarm Control Panel

An FACP that comes with one or more alarm zones. It can only connect conventional devices.

Fire Command Center

The room or principal location wherein the FACP and other life safety system are located to display and monitor all fire alarms and system troubles, and from which all output functions are automatically and manually controlled.

Manual Fire Alarm Station

An FDAS component that is manually operated to initiate a fire alarm signal.

Notification Appliance

An FDAS component such as a bell, horn, speaker, strobe, or text display that provides audible or visible outputs, or both.

Audible Notification Appliance

A notification appliance that warns by the sense of hearing

Exit Marking Audible Notification Appliance

An audible notification appliance that marks building exits, floor exits, stairwells, or paths to exits for the purpose of evacuation.

Visible Notification Appliance

A notification appliance that warns by the sense of sight.

Tactile Notification Appliance

A notification appliance that warns by the sense OF touch or vibration.

Personnel

People, who install, maintain, service, test, and/or inspect fire detection and alarm system.

Maintenance and Service Personnel

Individuals who perform cleaning, adjustments, replacements of equipment & components, system programming, and other maintenance work according to the manufacturer’s recommendations for the system to perform as required.

Testing Personnel

Individuals who perform physical checks, tests, and procedures to determine whether a system performs as required for acceptance or reacceptance.

Power Supply

It is the source of electricity that provides the power needed to operate the FACP, and consequently all devices connected to it.

Primary Power Supply

It is the 220VAC power voltage from the electrical utility company. Within the FACP it is converted to the system voltage of 24VDC.

Secondary Power Supply

When there is a failure of the primary power supply, the batteries (serving as the secondary power supply) automatically switch over t0 Provide uninterrupted power to the system.

Semi-addressable System

A system consisting of an addressable fire alarm control panel and conventional devices connected to it through input addressable modules.

Shall

Indicates a mandatory requirement.

Should

Indicates a recommendation, but not required.

Bank Style Cameras

are rectangular. They can be used indoors or outside, if used with a camera housing. Features such as back light compensation (BLC) are included. This is probably the most versatile camera style because of it's ability to change lenses and adapt to most lighting conditions.

Color Day/Night

Mainly used for outdoor applications. Is color by day and automatically switches to B/W at night using infrared illuminators? Some do not use illuminators but switch to low Lux B/W mode at certain light levels. Produces clean clear picture

Bullet Cameras

Can be used indoors or outdoor. Has built-in weatherproof housing. General-purpose camera with few bells and whistles. Cannot change lenses

Miniature & Hidden Cameras.

Mainly for indoors use. Disguised in ordinary items such as alarm clock radios

CCTV monitors can provide up to ____ lines of resolution compared to about 300 lines on a TV.

“Quad Monitor”.

Many low-end camera systems use a _____. They combine a quad processor and a CCTV monitor. A quad processor let's you display 1 camera at a time, switch between cameras on a timed interval or display all 4 cameras at once. In theory this sounds like a good idea. In reality there are multiple problems associated with these systems
