1. Key Functions of Emergency Warning and Intercom System
- Real-time Alerts: Covers the entire building, ensuring all occupants receive timely emergency notifications.
- Voice Communication: Allows remote-controlled evacuation instructions to prevent confusion.
- Adaptability for Sensitive Environments: In aged care facilities and hospitals, alarm volume and content can be adjusted to minimize distress among residents and patients.
Additionally, emergency warning and intercom system differs from Occupant Warning Systems, which is designed for smaller buildings and primarily provides basic sound and light alarms, whereas emergency warning and intercom system offers advanced control and integration capabilities, making it ideal for complex structures.
2. Applicable Buildings and Compliance Requirements
According to NCC 2022 VOLUME ONE- part E4- performance requirements E4D9, the following buildings must be equipped with emergency warning and intercom system that meets AS 1670.4 standards:
- High-rise buildings (above 25 meters in height)
- Schools and educational institutions (more than three stories)
- Hospitals and aged care facilities (with a floor area over 1,000㎡ or more than two stories)
- Theaters, auditoriums, and public venues (with a floor area over 1,000㎡ or more than two stories)
Ensuring compliance not only enhances building safety but also reduces legal liabilities for property owners and managers.
