Conventional beam detectors are fire alarm sensors that are used in large and high-ceilinged spaces. They work by emitting a powerful beam of infrared light that directly touches the other side of the wall, and if fire smoke reflects it or obscures it, the fire alarm will be triggered. This device is essential for installing a reliable fire detection system for commercial spaces like warehouses, manufacturing facilities, and more. They are highly accurate and are designed to be very durable and work in various types of industrial environments. The outer casing of the detectors protect its internal components from dust, dirt, and water damage. Choosing the best quality beam detectors can be a difficult task with so many options available online. This is why we have curated this blog to reveal the top 10 best conventional beam detectors to buy from top brands for higher safety purposes.
What is a Conventional Beam Detector?
Conventional beam detectors are specialized sensors that use infrared beams to detect fire hazards. These detectors emit a beam of infrared light all the way to the other end, where the receiver is installed; if it gets obscured by the smoke, the fire alarms are activated. These types of detectors are considered ideal for large spaces with high ceilings, where heat detectors are not so effective. They provide excellent protection by accurately detecting up to 100 meters.
There are two types of detectors: conventional and addressable. The conventional beam detectors can only transmit their zone location to the control panel if a fire outbreak occurs, whereas the addressable ones can communicate their exact location for precise tracking of the fire hazard.
Common Types of Conventional Beam Detectors to Choose From
Reflective Beam Detectors
These are also called single-end beam detectors that are very commonly used in residential as well as commercial spaces. These devices have a transmitter and receiver installed on the same wall and a reflector that is installed on the opposite wall. When it emits the infrared light, it gets reflected back to the receiver. But when the smoke obscures it, the device triggers the alarm systems.
End-to-End (Transmitter-Receiver) Detectors
These types of detectors are also called projected beam detectors that allow accurate detection of fire hazards in large spaces like warehouses and auditoriums. Their installation is very simple in which a transmitter is installed on one wall, and the receiver is installed exactly in a straight alignment to the other wall. When the beam is projected, the receiver shows no sign of fire hazards, but when smoke disrupts the beam, the alarm goes on.
Motorized Auto-Aligning Detectors
Motorized auto-aligning detectors are designed to adjust their position and keep the infrared beam emitting in a straight line through motorized mounts. Over time, buildings tend to shift, vibrate, and settle with minimal shifts, so that these detectors can sense and align themselves automatically according to it.
Double Beam (UV/IR) Detectors
These types of detectors are used where the false fire alarm is most likely to happen. They are designed for complex and high risk environments for better detection efficiency. These devices emit both ultraviolet (UV) and infrared rays for higher accuracy, because both UV and IR wavelengths react differently which eliminates the risk of false warnings.
How to Choose the Right Conventional Beam Detector for Your Fire Alarm Systems?
Here are the key points to consider to select the right conventional beam detectors:
Measure Distance
These types of detectors use a transmitter and receiver to emit IR rays and receive it to detect any fire outbreaks. To install them, you will have to measure the total distance up to which they are highly effective, which is up to 100 to 150 meters. They are commonly used for large spaces where one wall has a transmitter and another has a receiver.
Installation Environment
Beam detectors can accurately sense fire hazards even in rough environments, but cannot be used in extreme conditions with the presence of corrosive gases, high humidity levels, and intense temperatures.
Self-Aligning vs Regular Beam Detectors
Conventional beam detectors have special types of self-aligning variants that have built-in motorized mounts. This technology helps the detector to self-align the IR or UV rays in a straight line for efficient detection of fire outbreaks when the building vibrates and shifts over time, changing the angle of the rays.
Adjustable Sensitivity
Make sure that your new detector comes with adjustable sensitivity to customize it as per the environmental conditions. Because of this, minor dust or steam cannot affect the accuracy of the detection systems.
