What is a PA (public address) system?

A public address system distributes clear, audible sound to a defined space using an electronic amplifier, one or more microphones and loudspeakers. Systems range from a single amplifier and speaker pair for a small room to fully zoned networks covering an industrial site, shopping centre or stadium.

What's the difference between a small and a large PA system?

Small PA systems typically provide 50 to 200 watts of power and suit conferencing, churches or school auditoriums. Large PA systems are designed to cover much bigger spaces, such as industrial sites, outdoor complexes, stadiums and campuses, and are also used to alert people in large volumes during emergencies.

What is a telephone paging system?

A telephone paging system uses a PBX telephone system's paging facilities alongside a PA amplifier, so any handset on the network can act as a paging station. This is a practical alternative to bulky microphone-only PA systems, particularly for schools with multiple buildings and access points.

What is an IP PA system and how is it different from analogue?

An IP PA system runs over standard network cabling (Cat6/Cat6a) using PoE, instead of dedicated 70V or 100V analogue speaker lines. This can significantly reduce cabling costs on larger sites, while enabling remote monitoring, zone-by-zone control and easier future expansion.

What is a PAVA (public address and voice alarm) system?

A PAVA system links a public address system directly to fire detection, so a verified fire signal automatically triggers pre-recorded evacuation messages in the affected zone. People respond significantly faster to a clear spoken instruction than to a siren alone, making PAVA a key part of modern life-safety design.

Can a PA system integrate with fire detection for evacuation?

Yes. Our PA systems can be integrated with fire detection so that a verified alarm automatically triggers zoned, pre-recorded voice evacuation messages, sirens and access-controlled door releases, without depending on someone being present to operate a microphone.

What is phased or zone-by-zone evacuation?

Phased evacuation alerts the area nearest the emergency first, followed by adjoining zones, rather than sounding a building-wide alarm all at once. This staged approach is considered best practice for high-occupancy buildings, as it reduces bottlenecks and congestion on stairwells and exits.

Can a PA system be used for background music as well as announcements?

Yes. Most PA systems support a CD player, radio or streaming input alongside microphone paging, so the same system can play background music during normal operation and switch to priority announcements or emergency messaging when needed.

How much does a PA system cost in South Africa?

Cost depends on the size of the venue, the number of zones and speakers, whether the system is analogue or IP-based, and any integration with fire detection for voice evacuation. A free on-site assessment gives an accurate, tailored quote for your PA system installation.

Do you install PA systems nationwide?

Yes. CCTV Security Surveillance has branches in Gauteng, KwaZulu-Natal, Western Cape and Eastern Cape and supplies and installs PA systems of every size for businesses, schools, venues and industrial sites across all nine provinces of South Africa.

The Risk of No Clear Mass Communication

!Sirens and alarm tones alone don't tell people what's happening or where to go
!Ageing 70V/100V analogue paging is expensive to cable and hard to expand across a large site
!Announcements can't reach every zone evenly in large, noisy or multi-building environments
!No link between fire detection and evacuation announcements slows down a safe response
!Bulky microphone-only systems limit where staff can make an announcement from

What a Professional PA System Delivers

✓People react up to 50% faster to a clear spoken instruction than a siren alone
✓IP/PoE systems that run on your existing network, cutting cabling costs significantly
✓Automatic, zone-by-zone voice evacuation triggered directly by fire detection
✓One system for paging, background music and life-safety announcements

What Is a Public Address (PA) System?

A public address system distributes clear, audible sound to a defined space using an electronic amplifier, one or more microphones and loudspeakers. A PA system can be as simple as a single amplifier and speaker pair for a small conference room, or as complex as a fully zoned, networked system covering an industrial site, shopping centre or stadium.

CCTV Security Surveillance has established itself as a leading provider of public address systems throughout South Africa. With branches in Gauteng, KwaZulu-Natal, Western Cape and Eastern Cape, we supply and install PA systems of every size nationwide, with localised support and expertise.

Types of PA Systems We Install

We design and install the full range of public address configurations, matched to your venue, audience size and budget.

Small PA Systems

A microphone, amplifier and one or more loudspeakers delivering 50 to 200 watts of power — suited to small venues for conferencing, churches and school auditoriums, with CD or radio input for background music.

Large PA Systems

Systems designed to cover much larger spaces, such as industrial sites, outdoor complexes, stadiums, colleges and university campuses, including alerting people in large volumes during emergencies.

Telephone Paging Systems

PBX telephone systems with paging facilities, using a PA amplifier so any handset becomes a paging station — a practical alternative to bulky microphone systems, ideal for schools with multiple access points.

Small Venue Systems

Simple setups for bars and clubs using large front speakers and subwoofers aimed at the audience, with smaller monitor speakers aimed back at performers.

Large Venue Systems

Concert-grade systems built as two separate rigs — a main system for the crowd and a monitor system for performers — using mixing boards, amplifiers, speakers and sound processing equipment.

IP & Voice Evacuation Systems

Network-based PA and PAVA (public address & voice alarm) systems that combine everyday paging with automatic, zoned emergency evacuation messaging linked to fire detection.

IP PA Systems: The Modern Standard

IP/PoE network-based PA systems have become the standard for new installations, running over Cat6/Cat6a network cabling instead of dedicated 70V or 100V speaker lines. This can reduce cabling costs significantly on larger sites, while enabling remote monitoring, zone-by-zone control and easy expansion as a building grows. Because IP PA systems can share your existing network infrastructure, they deploy faster and integrate more easily with CCTV, access control and fire systems than legacy analogue paging.

Public Address & Voice Evacuation (PAVA)

In an emergency, a clear spoken instruction moves people to safety faster than a siren alone. A public address and voice alarm (PAVA) system links your PA system directly to fire detection, so a verified fire signal automatically triggers pre-recorded evacuation messages in the affected zone, without depending on someone being present to operate a microphone. Best-practice PAVA design uses phased, zone-by-zone evacuation — alerting the area nearest the emergency first to prevent bottlenecks — with clear, intelligible messaging throughout the building.

Voice evacuation is most effective as part of a connected system. See our fire detection systems, which are designed to trigger sirens, voice evacuation and access-controlled door releases automatically the moment a fire is verified.

Where PA Systems Are Used

Schools & Auditoriums

Classroom paging, assembly announcements and telephone paging systems for schools with multiple buildings and access points.
