SMATV system

SMATV (Satellite Master Antenna Television System), is a community Distribution system for channels received from a variety of satellites along with Terrestrial signals & Radio. All these receptions will be combined with the help of “MULTISWITCH” and distributed with an individual and separate cable to each household in the community building. The size of the network varies from small to large. For huge buildings where coaxial cables are unsuitable, fiber optic solutions can utilize with SMATV systems. With modern equipment, any type of SMATV network can be constructed with convenience.

PA system

A public address system (PA system) is an electronic sound amplification and distribution system with a microphone, amplifier and loudspeakers, used to allow a person to address a large public, for example for announcements of movements at large shopping mall.

Intercom system

An intercom (intercommunication device), talkback or door phone is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones, and to other intercom systems. Some intercom systems incorporate control of devices such as signal lights and door latches.

ELV System Installation

ELV, which stands for extra-low voltage, refers to an electrical system with voltage lower than 50V (for alternating current) or 120V (for direct current). In most cases, it is designed in such a manner to keep the voltage within the designated threshold under standard circumstances as well as during single-fault situations. A typical ELV system installation can be further divided into several types including:(1)-Protection ELV (PELV) – connected to earth;(2)Separated ELV (SELV) – disconnected from earth;(3)Functional ELV (FELV) – anthing other than PELV and SELV. You can find ELV systems in numerous devices including CCTV cameras,

fire alarms, and access control panels. One of the main reasons ELV systems are utilized is to reduce the hazard of lethal electrocution. This explains why they are commonly found in places with potential hazards such as aquatic centers and outdoor facilities which are prone to extreme weather conditions. As far as an impeccable ELV system installation is concerned, DEC Contract is undoubtedly the best choice for you. Our high quality workmanship is some of the best in Kuala Lumpur and Selangor. Simply reach out to us via phone or email, or you can visit our office at Taman Shamelin Perkasa for further inquiries.

Why Choose ELV Systems

ELV systems operate at low voltage levels (under 50V AC or 120V DC), dramatically reducing electrical shock risks and creating safer environments for occupants. These systems consume significantly less power than traditional systems, resulting in 20-30% energy savings and lower operational costs. ELV systems integrate seamlessly with building automation platforms and smart technologies, enabling centralized control of lighting, security, HVAC, and access systems remotely. Installation is cost-effective since components, cabling, and infrastructure are simpler and less expensive than high-voltage alternatives. The reduced electrical stress means components deteriorate slowly, requiring minimal maintenance and reducing long-term repair expenses. For businesses of all sizes, ELV systems provide reliable, future-proof solutions that enhance safety while delivering substantial savings on energy and maintenance costs over their operational lifespan.

ELV System Applications

ELV systems are essential across diverse sectors. Commercial buildings utilize access control, CCTV, and PA systems for security and communication. Residential complexes implement keyless entry, intercom networks, and surveillance for resident safety. Healthcare facilities rely on nurse call systems, fire alarms, and access control for patient and staff protection. Educational institutions deploy security systems and emergency communication networks protecting students and faculty. Government facilities require highly secure ELV infrastructure for access control and critical operations. Hospitality businesses enhance guest experience through smart room management and emergency systems. Industrial facilities implement safety monitoring, access restrictions, and emergency communication across manufacturing floors. Regardless of industry, professional ELV system installation ensures operational efficiency, enhanced security, regulatory compliance, and significant cost savings through reliable automation and safety integration.

Frequently Asked Questions

What is ELV installation?

ELV installation refers to the installation of Extra-Low Voltage systems, which typically operate at voltages below 50 volts AC or 120 volts DC. These low-voltage systems are safe to install and maintain and are commonly used for communication, security, surveillance, fire alarm, and building automation systems.

What is an ELV system used for?

An ELV system is used to enhance safety, reduce energy consumption, and provide a reliable infrastructure for building automation, security, communication, access control, CCTV, and other low-voltage applications.

What are the three types of ELV systems?

The three main types of ELV systems are Protective Extra-Low Voltage (PELV), Separated Extra-Low Voltage (SELV), and Functional Extra-Low Voltage (FELV). Each type is designed for different applications and levels of electrical protection based on industry standards.

What is the purpose of ELV?

The purpose of an ELV system is to provide a safe and reliable power supply for low-voltage applications while reducing the risk of electric shock. ELV systems support essential building services such as security, communication, fire detection, access control, and automation, ensuring efficient and dependable operation.

What is an ELV wiring system?

An ELV wiring system uses an electricity supply voltage that is part of the low-voltage band and carries a low risk of dangerous electrical shock. It is designed to safely distribute power and signals for systems such as CCTV, access control, data networking, intercoms, and fire alarm installations, in accordance with relevant electrical standards.
