Opera House Project
Introductions

This project installs a comprehensive fire safety early warning system for an opera house in Sydney. There are 498 seats in the auditorium, a spacious lobby, and main access corridors. As a public cultural facility in Sydney, we welcome audiences of all ages to the opera house. The public spaces and screening rooms are designed for comfort without compromising user experience. There is a typical high-risk commercial service establishment for its diverse functional spaces and high volume of people.

Referring to the building’s functional layout and operational requirements and product types and technical characteristics, the project is comprehensively designed and planned the fire detection and alarm system with AS 3786 / AS 1670.1 fire safety regulation for this opera house. The system uses 41pcs alarms (smoke alarms, heat alarms, CO alarms) and controllers. It enables early fire warnings, lower false alarms, timely evacuation, easy maintenance and emergency response in the initial fire or carbon monoxide leak stage and simultaneously gives the information to opera house management and audiences.

😔 Challenges

Dense crowds and zero false alarms: There are air conditioning recirculation, smoke sprayers (for special effects), and low-light conditions in the opera houses, which can potentially trigger smoke alarms.
Differences in Functional Spaces: Various people go to different functional spaces, such as the ticket area, rest area, popcorn kitchen in the same air ventilation system, and may make false alarms or missed alarms.
Equipment Concealment: Alarms must not detract from the overall opera house aesthetic, and the alarm lights and buzzers must meet the standards while minimizing disruption to watching movies.
Large space and a high ceiling: Following normal installing method, the smoke sensitivity will be lower in large space and a high ceiling.

☺️ Solutions

Differentiated detection technology Combination together: Different types of detectors are used in different areas: Photoelectric smoke detectors are used in reading and book storage areas.
False Alarm Resistance Design Logic: The engineers optimize MCU multi-parameter alarm signal and algorithm to filter environmental noise and photo sensor sensitivity to reduce false alarm.
Double Verification of Installation and Commissioning: Each Alarm installing location on ceilings or high walls and avoiding near ventilation openings, air conditioning vents, should have the cross-verification for installation height, airflow impact, and measured response time.
Aesthetics and Functionality together: The alarms use concealing wiring and wireless connectivity and is installed in a not easily noticeable location, but the function is not affected. Adjusting LED brightness and sound without disrupting the viewing experience meets the standard.
Increase the number of alarms: Reducing standard installation spacing and increasing the number of alarms can avoid missing alarms.

How Many Alarms

Explore how different areas are equipped with the appropriate types and number of alarms, ensuring effective fire safety across various environments.

Smoke Alarms

Following smoke alarms spacing requirements of NCC and AS 1670.1 standard (applicable to Austria) and the risk.
Entrance + Selling tickets area + Public corridors + Snack bars + Lounge + Auxiliary areas + 498-seat Auditorium

4pcs smoke detectors for entrance and selling tickets area
4pcs smoke detectors for public corridors
5pcs smoke detectors for snack bars, lounge, and auxiliary areas
21pcs smoke detectors for 498-seat Auditorium

This project used total 30 pcs smoke detectors, the details are as follows:

Choose The Right Alarms For Opera House

Based on the opera house’s spatial type and risk characteristics, the project will achieve fire (smoke/temperature rise) detection in all critical areas within the opera house and CO detection and early warning in areas where carbon monoxide leaks may occur (such as boiler rooms and machine rooms), so the project used three type alarms:
