Large Space Smoke Detection Solution for Warehouses, Malls, Halls, Workshops, and Industrial Buildings
Detecting smoke in large open spaces is one of the biggest challenges in modern fire protection design. Buildings such as warehouses, shopping malls, exhibition halls, hangars, workshops, museums, archives, and power plants often have high ceilings, wide structures, and complex layouts that make traditional point-type smoke detection difficult.
In these environments, smoke may travel across a large area before reaching a conventional smoke detector. Installing a large number of point detectors can increase installation costs, maintenance difficulty, and system complexity.
A linear beam smoke detector provides an effective solution by monitoring smoke across a long optical path instead of detecting smoke at only one point.
The HazenFire AT-B01 Linear Beam Smoke Detector is designed for large open spaces requiring reliable and wide-area smoke detection. Using reflective infrared beam technology, AT-B01 provides long-distance monitoring, stable performance, and easy integration with modern fire alarm systems.
Why Smoke Detection Is Challenging in Large Open Spaces
Large buildings create unique fire detection challenges because of:
- High ceilings
- Large floor areas
- Long structural spans
- Complex ventilation systems
- Air movement and airflow changes
- Difficult maintenance access
In warehouses, smoke may rise above storage racks before reaching detector locations. In shopping malls and public halls, open atriums and decorative structures can affect detector placement. In industrial workshops and hangars, large equipment and high installation points make traditional detector maintenance more difficult.
For museums, archives, and historic buildings, fire detection solutions must also minimize visual impact while maintaining reliable protection.
A linear beam smoke detector solves these challenges by monitoring a long distance between the detector and reflector, allowing one detection system to cover a large open area when properly designed.
How Does a Reflective Beam Smoke Detector Work?
A reflective beam smoke detector consists of:
- Detector unit
- Reflector unit
The detector sends an infrared beam toward the reflector and receives the reflected signal.
Under normal conditions:
- The infrared beam travels between detector and reflector
- The received signal remains stable
- The system operates normally
When smoke enters the beam path:
- Smoke particles reduce infrared signal strength
- The detector analyzes the signal change
- Internal processing determines alarm conditions
- Fire alarm output is activated when the threshold is reached
This operating principle allows beam smoke detectors to identify smoke over long distances, making them ideal for large buildings where point detection is difficult.

Installation Design Considerations
Correct installation is essential for reliable beam smoke detection performance.
For HazenFire AT-B01 installation:
- Detector and reflector should be installed at the same horizontal level
- Beam path must remain clear of obstacles
- Fixed structures, moving objects, and temporary materials should not block the optical path
- Detector alignment should be carefully adjusted
Recommended installation guidelines:
| Item | Requirement |
|---|---|
| Beam position | 0.3 m–1.0 m below ceiling |
| Maximum installation height | Up to 20 m |
| Detection distance | 5 m–100 m |
| Optical path | Must remain free from obstruction |
| Beam interference area | Keep clear around optical axis |
Proper installation ensures stable communication between the detector and reflector and improves long-term detection reliability.
Reflector Selection and Beam Alignment
Reflector selection depends on the detection distance.
Recommended configuration:
| Detection Distance | Reflector Requirement |
| Up to 50 m | Two reflector blocks |
| 50 m–100 m | Four reflector blocks |
Reflectors should be installed on the same plane and positioned carefully to maintain accurate beam reflection.
The detector should have a clear line of sight to the reflector without interference from equipment, structures, or environmental obstacles.
Commissioning with Built-In Laser Aiming
Commissioning is an important step in beam smoke detector installation.
The HazenFire AT-B01 includes a built-in laser module that helps installers quickly complete optical alignment.
During commissioning:
- Power is supplied to the detector
- The commissioning function is activated
- The laser points toward the reflector
- Installation angle is adjusted until alignment is achieved
- LED indicators and buzzer signals confirm beam strength
This feature reduces installation time and simplifies alignment, especially in buildings with high ceilings where accurate positioning is difficult.
Connection with Fire Alarm Control Systems
The HazenFire AT-B01 can be integrated with different fire alarm systems through:
- Fire alarm relay output
- Fault relay output
- Input modules
- RS485 communication
The detector supports flexible wiring through:
- DC24V power input
- Alarm output terminals
- Fault output terminals
- RS485 communication terminals
This allows easy connection with addressable and conventional fire alarm control systems depending on project requirements.
