Beam Detection

Fire Detection System

Beam detectors provide more efficient smoke detection than standard optical detection in large open areas. Utilising reflective detection technology, the beam detector is made up of two parts: the transmitter-receiver that emits a constant beam of infra-red light and the reflector with a prism that angles the beam back at the transmitter-receiver.

Beam Smoke Detectors

Fire detection is required to protect life and property. When protecting life, you must ensure that everyone can escape safely within the appropriate time if a fire occurs. When protecting property, you must make sure that the system alerts the fire brigade as soon as possible to ensure minimal damage to the building. 

All fire alarm systems need to comply with BS5839-1 to ensure the safest practice.

Beam Detection Installation

Reflective beam detectors work by blending the transmitter and receiver into one unit and sending the beam via a reflector at the opposite end of the protected space. This enables single point cabling, and therefore installation time (and cost) is considerably reduced.

We can supply, install, maintain, and commission fire detection  systems to the highest standards with our BAFE accreditation and FIA membership. See our industry-leading accreditations.

Clearview can also provide 24hr monitoring on all fire detection systems through our command centre.

How Does a Beam Fire Detection System Work?

Fire and fault signals process to the control panel through standard loop wiring (conventional, addressable, or wireless) operated by an interface linked to the beam detector. The transmitter-receiver triggers the input signals on the interface when smoke is detected across the large space it is protecting. Beam detectors work better in larger, open space buildings than traditional smoke detection systems as they can be installed where smoke gathers. Due to stratification, smoke fields form in an inverted cone, rarely reaching the ceiling. Beam detectors are designed for premises with temperature extremes, excessive dirt, high humidity, and corrosive gasses. However, they are not best suited to be installed in outdoor areas, glass atriums, and areas where ice or condensation occurs, as this creates a challenge for the system.

Why Install Beam Fire Detection?

Beam detectors can detect the spread of smoke throughout a wide area by utilising the obscuration method. The detector can identify a fire when the smoke particles obscure the infra-red lighting within the sensing path. A fire condition is applied if the infra-red beam is blocked with sufficient smoke particles. Therefore the main advantage of this fire detection system is that it can identify a fire before it spreads, saving lives and limiting the damage caused within the event of a fire. For this reason, beam smoke detection is more commonly used, particularly in larger establishments such as warehouses, shopping centres, museums, hotels, leisure centres, and cathedrals. With these establishments having such open spaces, a fire could rapidly spread throughout the building, so early detection is essential.
