• Inputs for additional analog audio signals.
• General-purpose inputs and outputs to connect third- party systems.
Leading systems can connect more than 4,000 microphones into the main unit and provide centralised control of around 1,000 public address and emergency zones. These systems also allow for multiple main units to be networked on site for additional reach.
Simple testing and maintenance To help facility teams easily monitor equipment health and performance, some PAVA providers offer remote system monitoring apps where authorised users can access a mobile dashboard to check system status. The PAVA system will also send detailed notifications to a user’s mobile device in the event of an emergency or system fault.
Remote access software and cloud solutions also allow authorised installers and maintenance companies to connect to the system for commissioning, log checks and fault verification, which can minimise or even eliminate on-site visits. Software faults can be resolved remotely by a technician from the office while hardware faults, tools and replacement parts can be prepared for an on-site visit.
Improved evacuation PAVA systems can simultaneously send live audio and recorded messages to separate zones in a building or space. In an emergency, this capability helps prevent bottlenecks by allowing for automatic, phased, zone-by- zone evacuation, starting with the location nearest to the emergency event.
Integration with building systems In today's intelligent building environments, new systems

must seamlessly integrate with existing infrastructure. Analog PAVA systems work with fire alarms but lack the connectivity to network with other building technologies. In comparison, IP-based architecture allows easier integration with other systems like fire alarm, closed- circuit television (CCTV), access control and building automation systems (BAS).
Leading PAVA systems based on the AES67
Communication protocol allow audio signal transmission over IP. The open standard allows for seamless integration and interoperability in smart environments and enables multicast streaming. Enterprise-lev el organisations can remotely broadcast audio information, announcements or background music from a central location via multiple PAVA systems set up in all sites at the same time.
To maintain system integrity and safeguard against cyberthreats, PAVA systems should adhere to robust cybersecurity standards such as IEC 62443-4-1 and 4-2.
A smart investment in safety Choosing the right PAVA system is more than meeting minimum requirements. It is an investment in safer evacuations, simpler maintenance and better long-term building safety. By prioritising reliability, scalability and integration, facility teams can leverage PAVA systems to build a communication strategy that supports both emergency readiness and everyday operations.
