What is an Open Space Image Detection System?

Open space image detector systems (OSID) or optical smoke detectors are an innovative alternative to standard fire prevention systems. This type of system is usually installed in large open spaces that require greater sensitivity to real signals of fire.

It works by using a camera like device with a wide view that is aligned with the opposite wall. This enables the protected area to be viewed in its entirety.

How does an OSID System Work?

How does an OSID System Work?

Large, open spaces such as warehouses, airports, train stations, stadiums and shopping centres pose unique challenges to reliable fire detection due to their environmental nature and openness. This can mean they are more prone to false alarms when traditional fire detections systems are installed.

OSID is designed specifically for these environments, enabling early detection of real fire signals, particularly of slow smouldering fires, to prompt an early response which will help to save lives and prevent service disruptions.

The system uses a sophisticated algorithm to map and compare the strength of infrared (IR) and ultraviolet (UV) light signals from detectors configured in the area.

The detector works by emitting infrared and ultraviolet signals to the imager. If there are any alterations in the light due to smoke particles being detected then the alarm will sound.

Because this system detects smoke via light particles the chance of false or unwanted alarms is significantly reduced. Open space image detectors are also resilient to building movement as well as any obstructions such as insects or dust. This is due to how it uses code ultraviolet and infrared which respond differently to smoke.

The installation of the system is simple and quick using a laser alignment tool. It can be also be fitted with an alkaline or a lithium battery that lasts 5 years.

The ideal environments in which open space image detector systems can be installed in include:

  • Airports
  • Train Stations
  • Museums
  • Stadiums and indoor theatres
  • Warehouses & Distribution Centres

Features Offered by OSID

OSID systems may be configured to protect a range of spaces, regardlessof shape. The protection zone or “fire web” is determined by the placement of OSID detectors. Multi-emitter solutions provide a true 3D arrangement.

British Standards BS 5839-1:2017

This is a code of practice for fire detection and fire alarm systems for buildings. The code provides recommendations for the planning, design, installation, commissioning and maintenance of fire detection and fire alarm systems in and around buildings other than dwellings. It does not recommend whether or not a fire alarm system should be installed in any given premises. To comply with this Standard and the Regulatory Reform (Fire Safety) Order 2005, a fire safety risk assessment must be carried out by a competent person.
