Learn more about Addressable smoke sensors
Addressable Smoke Sensors are advanced detection devices used within an addressable fire alarm system, where each sensor has its own unique digital address. This allows the control panel to pinpoint the exact detector that has activated, enabling faster, more targeted responses during a fire event.
Equipped with high-sensitivity optical detection technology, these sensors continuously monitor for early signs of smoke particles.
Their intelligent communication with the main control panel helps reduce false alarms by analysing environmental conditions and adjusting sensitivity where necessary.
These sensors are built for commercial, industrial, and residential environments. They support easy installation, automatic device mapping, and remote diagnostics, making system maintenance more efficient for engineers and facilities teams. With robust, modern design and compatibility with Inbuild UK's systems, they deliver reliable life-safety performance for a wide range of applications.
Frequently Asked Questions
What is an addressable smoke sensor?
What is an addressable smoke sensor?
An addressable smoke sensor is a fire detector that has a unique digital address, allowing the fire alarm control panel to identify its exact location when it detects smoke.
Where should a fire control panel be located?
Where should a fire control panel be located?
For optimal effectiveness and compliance with UK fire safety regulations, the placement of a fire control panel is paramount. Proper placement is crucial for ensuring quick access and operation in a fire, thereby safeguarding both lives and property. Key guidelines for its location include:
- Accessibility: The panel should be easily accessible to firefighters and building managers, typically situated near the main entrance or within a secure area.
- Protection: It must be in an area shielded from fire and smoke to guarantee continued operation during an emergency.
- Clear Identification: The panel requires clear signage indicating its purpose and location, enabling rapid identification by emergency responders.
- Regulatory Compliance: Its placement must adhere to BS 5839-1:2017 (Fire Detection and Alarm Systems for Buildings) and the Regulatory Reform (Fire Safety) Order 2005.
Do addressable smoke sensors reduce false alarms?
Do addressable smoke sensors reduce false alarms?
Yes. Many models use intelligent algorithms and environmental compensation to reduce the likelihood of false alarms.
How is it different from a conventional smoke detector?
How is it different from a conventional smoke detector?
Conventional detectors only trigger a general zone alarm, while addressable detectors provide specific device-level information, making fault-finding and response quicker.
Do addressable smoke sensors reduce false alarms?
Do addressable smoke sensors reduce false alarms?
Yes. Many models use intelligent algorithms and environmental compensation to reduce the likelihood of false alarms.
Are they easy to maintain?
Are they easy to maintain?
Yes. Because each device reports its status, engineers can quickly identify faults or contamination, reducing inspection time and improving maintenance efficiency.
Are these sensors compatible with all systems?
Are these sensors compatible with all systems?
They must be used with a compatible addressable fire alarm control panel. Always check system integration requirements before installation.
