There are three basic types operating by ionization, light scattering and light obscuring. Ionisation These generally contain two chambers. One is used as a reference to compensate for changes in ambient temperature, humidity or pressure. The second contains a radioactive source, usually alpha particle, which ionizes the air passing through the chamber where a current flows between two electrodes. When any of the products of combustion enters the chamber the current flow decreases. This drop is used to initiate an alarm. Light obscuring In the obscuring type the smoke interferes with a light beam between a light source and photo cell, the variation in photo cell output being used to initiate an alarm. This type of detection can be used to protect large areas with the source and photo cell positioned some distance apart. Light scattering The light scattering detector operates on the Tyndall effect, a photo cell and light source are separated from each other by a darkened chamber such that the light source does not fall on the photo cell. The passage of smoke into the chamber causes the light from the source to be scattered and fall on the photo cell, the cell output being used to initiate an alarm. The light scattering and light obscuring detectors both, detect visible smoke. The ionization detector and light scattering detector are normally each a single unit suitable for BESA conduit box mounting. In some models the smoke detector head is attached to the main body by a bayonet fixing for easy removal for maintenance or replacement. It should be noted that some detectors are suitable for two-wire circuits whereas others require three or four wire connections. Smoke detectors require a continuous power supply. Under quiescent conditions they draw a current of some 100 micro amps, and under alarm conditions, some 45 milliamps. This needs to be borne in mind when sizing the power supply. Smoke detectors generally operate on 24 d.c. Refer to British Standard Codes of Practice and manufacturers literature for information regarding the positioning of smoke detectors. Detectors are not suitable for positioning in kitchens, near fireplaces or areas with excessive exhaust fumes, or within 2m of air supply ducts or diffusers.

Fire Project has make several installation of SecuriRAS ASD 535 aspirating smoke detector, which is the new generation of highly sensitive, active smoke detection systems. It offers application-specific sensitivity adjustment alongside pre-signalling and pollution analyses. The SecuriRAS ASD 535 detects even minuscule glowing and smouldering fires and can be deployed practically anywhere. Typical applications include: • Room surveillance • High-rack warehouses and distribution centres • Archive rooms • Intermediate ceilings and raised floors • Large halls • Museums, galleries, theatres, cinemas • Cultural artefact collections, historical buildings • Airports • Informatics and computer centres • Telecommunication centres • Laboratory and research centres • Electronic measuring rooms • Transformer rooms • Clean rooms • Refrigerated warehouses • Property surveillance • Telecommunication facilities • High and low-voltage distribution cabinets • Display cases • IT installations • CNC control systems • Invisible applications • Protection of cultural assets • Prison cells Select Fire Projects for new implementation of Securiton ASD - 535 aspirating smoke detection is most effective way for very early smoke detection application for small to medium size datacenter, UPS room, medical facilities, and telecommunication facilities. We support our clients from Designing up to Commissioning up to AMC. We also provide AMC–Annual Maintenance Contracts for all types of Fire & security Systems.

A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible or visual alarm from the detector itself.
