A BAS component, mini exchange in which you can input 2/3/4/more telephone-lines; can take out so many outputs

A security solution; audio video door entry systems integrated with electronic entry systems, video entry and access control systems

Packed with simple plug & play function.

Used in car parking sites, condominiums, toll collection, and industrial entrance

It detects, reports, and acts on hazardous fires in buildings.

Has the ability to permit or deny the use of a particular resource by a particular entry.

A family of a computer networking technologies for local area metwroks (LANs)

It is similar to a television, used to monitor the output of a video-generating device

An integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system.

An electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, or other memory medium within a device

It uses removable videotape cassettes containing magnetic tape to record audio and video from a television broadcast so it can be played back later

Transmits a signal from one place to another. The signal can be electrical, optical, or radio signal.

This is important in fields such as digital audio where streams of sampled data are manipulated

This is used to select between several different video sources.

A system for electronically capturing, recording, processing, storing, transmitting, or reconstructing a sequence of still images representing scenes in motion.

Makes speech unintelligible during transmission and restores it at reception

Receives or transmits radio or TV signal

Broadcasts or receives electromagnetic waves representing images and sound

Increase strength of signals passing through it

Detects the presence of radio signals or radioactivity

Reduces frequency distortion

Mixes two or more input signals to give a single output signal

Comprising the part of a tape recorder that reproduces the recorded material

Sets of electronic devices that are used together to transmit or record sound and convert electrical signals into images

A combination of transducing devices and associated equipment for picking up sound at one location and time and reproducing it ath the same or some other location and at the same or some later time.

A stand-alone electronic communications system intended for kimited or private exchange.

An electronic amplification system with a mixer, amplifier, and loudspeakers, used to reinforce sound and distributing the sound throughout a venue or building

Used to increase the level of of the electrical signals that represents from the sound source so that it can be heard at sufficient volume from the loudspeaker.

Device which converts the electrical impulses from thr amplifier into vibrations in the air which our ears interpret as sounds.

A system of providing television to consumers via radio frequency signals transmitted to televisions through fixed optical fibers or coaxial cables.

A system of providing television to consumers via radio frequency signals transmitted to televisions through fixed optical fibers or coaxial cables.

These make connections among the internal telephones of a private organization and connect them to the public switched telephone network (PSTN) via trunk lines

A document sent over the telephone line; its machine transmits pieces of paper to someone else instantly.

A telecommunication device that transmits and receives sound; operates principally by converting sound waves to electrical signals, and electrical signals to sound waves.

It contains a duplex coil to block the sound of your voice from reaching your ear, a bell so it can ring, and a touch-tone keypad and frequenct generator

Prevents shoplifting through special tags that are fixed to merchandise; a detection system sounds an alarm when it senses active tags

High level of interaction between the active fire system building wide communications, HVAC, and interactive smoke control systems

Monitoring and managing the mobile assets are the core functionalities of any company dealing with the services, delivery, or transport vehicles

Includes energy management systems and building controls (heating, ventilation, air conditioning, lighting, alarm systems, and electrical appliances)

The simultaneous control of the temperature, humidity, motion, and purity of the air in a confined space.

For summer cooling, what is the ideal temperature?

For summer cooling, what is the ideal relative humidity?

What is the ideal average air velocity for comfort (measured 36" above the floor)?

Also called hygrostat, it is a controller sensitive to the amount of humidity in the air

A controller which responds to changes in temperature

Instruments sensitive to changes in pressure.

These control the flow of air and are in the form of louvers

These are valves with variable orifices which are moved by motors to present smaller or larger openings as dorected by a thermostat

These are devices that use electrical energy to amplify or convert the power of a thermostat

Contains steam and are used to heating the air i.e., preheaters and reheaters

Used for heating the water which will be used in the spray chamber to add heat and humidity to the air

Consist of wire frames enclosing felt, cotton, or sponge through which the air is screened

Consist of metal deflecting plates or screens coated with viscous oil

Consist of corrugated galvanized iron sheets placed 1-1/8" apart which deflect the air flow about 30 degrees catching the wet dust on the surfaces

These fans are intended for moving air at comparatively high pressures and are commonly used in duct system

These fans are commonly used for wall exhausts

The following are methods of cooling and de-humidifying, except:

This evaporator is similar in operation to the shell and tube condenser

This may either be installed in the spray chamber so that the water sprayed into the air comes into contact with the cooling coils
