Open-area Smoke Imaging Detection (OSID)

Open-area Smoke Imaging Detection (OSID)

OSID Smoke Detection Open-area Smoke Imaging Detection (OSID) by Xtralis is a new innovation in projected beam smoke detection technology. By using advanced dual wavelength projected beams and optical imaging technology for early warning smoke detection, OSID provides a low-cost, reliable and easy-to-install solution that overcomes typical beam detection issues such as false alarm incidents and alignment difficulties. Unique Detection Technology The OSID system measures the level of smoke entering beams of light projected over an area of protection. A single OSID Imager can detect up to seven Emitters to provide a wide coverage area. Two innovations in smoke detection technology have been developed for the revolutionary OSID smoke detector: Dual Wavelength Particle Detection The beam projected from each Emitter contains a unique sequence of ultraviolet (UV) and infrared (IR) pulses that are synchronised with the Imager and enable the rejection of any unwanted light sources. By using two wavelengths of light to detect particles, the system is able to distinguish between particle sizes. The shorter UV wavelength interacts strongly with both small and large particles while the longer IR wavelength is affected only by larger particles. Dual wavelength path loss measurements therefore enable the detector to provide repeatable smoke obscuration measurements, while rejecting the presence of transient dust particles or solid intruding objects. Optical Imaging with a CMOS Imaging Chip An optical imaging array in the OSID Imager provides the detector with a wide viewing angle to locate and track multiple Emitters. Consequently, the system can tolerate a much less precise installation and can compensate for the drift caused by natural shifts in building structures. Optical filtering, high-speed image acquisition and intelligent software algorithms also enable the OSID system to provide new levels of stability and sensitivity with greater immunity to high level lighting variability. Operation Status information (Fire Alarm, Trouble and Power) is communicated through the Imager via Status LEDs, dedicated Trouble and Alarm relays, and the Remote Indicator interface. Specific Trouble (Fault) conditions are identified through coded flashes of the Trouble LED.

Simple Installation and Maintenance The OSID system consists of up to seven Emitters, for the 45 and 90 Imager units, located along the perimeter of the protected area, and an Imager mounted opposite. Each component can be mounted directly to the surface or can be secured with the supplied mounting brackets. Battery powered Emitters with three or five years battery life are also available to reduce installation time and cost.

106mm (4.2 ) OSID Smoke Detection On the Imager, a termination card provides all field wiring terminals, and DIP switches enable the user to configure the detector for particular applications. Alignment of the Emitter is simply achieved using a laser alignment tool to rotate the optical spheres until the laser beam projected from the alignment tool is close to the Imager. The Imager is aligned in a similar way so that its Field of View (FOV) encompasses all Emitters. A Trouble or Fault will be indicated if an Emitter is missing or outside the Imager field of view. The OSID system is highly tolerant to transient dust and dirt and requires little maintenance in practice. Preventative maintenance is limited to occasionally cleaning the optical faces of the detector components. The Imagers are equipped with an onboard event memory for diagnostic purposes. Connecting the OSID Diagnostic tool allows users to download this memory log for further alarm and fault analysis and troubleshooting. Configuration Options OSID systems may be configured to suit a range of detection spaces by selecting the number of Emitters and type of Imager. Each type of Imager differs by the lens used in the unit, which determines the field of view and range of the system. Imager Field of View Detection Range Max.

Light Shield for OSID Imagers Prevents Imager saturation from bright light sources in one-on-one applications Protects Imagers against bright light outside of a 30 viewing angle in oneon-one applications Quick and easy installation Fits all OSID Imagers Application Beam detectors are susceptible to saturation from direct sunlight most often when installed in an East-West direction and when the sun is low on the horizon. Background subtraction techniques and IR and UV filters make OSID far less susceptible to saturation than standard IR beams. OSID will never false alarm due to bright sunlight. However, severe saturation may in some cases affect the Emitter IR and UV signal and cause a fault to be reported. OSI-LS light shield is available for Imagers to prevent saturation from direct or reflected light. The light shield can only be used in end-to-end / one-on-one configurations. The light shield cannot be used in Multi-Emitter applications. The shield is easy to apply and protects against light outside of a 30 viewing angle. The light shield cannot be used in combination with an environmental housing.

Light Shield for OSID Imagers Installation The light shield is fitted with self-adhesive tape. To install, remove the backing paper from the adhesive, align the shield as in the photo, and apply force to affix the shield to the eyeball.

OSID Environmental Housing for Imagers and Emitters OSID-EH IP66, NEMA 4-4X for use in harsh environments Imager with extra viewing opening for Alarm and Fault LEDS Dedicated entry for OSP-001 FTDI cable Fast and easy installation- entry and exit opening for wiring Protects against dust and water Application Custom designed IP 66, NEMA 4-4X protective and environmental housings protect OSID imagers and emitters from dust and water ingress in industrial environments. The housings are only to be used with 1 on 1 systems. The glazed housings are made of ABS. The glass window causes minimal attenuation of the UV and IR beams. Installation and servicing is extremely easy. The imager housing has two glands for easy wiring. The Emitter housing can be used with both battery powered and 24V wired emitter. To access to the Imagers FTDI socket the lid needs to be removed. A separate cable inlet directly below the FTDI socket is normally sealed but can be fitted with an additional gland supplied with the enclosure for servicing or upgrading the imager. Both the imager and emitter housing have 3 pre-drilled screw connections for fixed mounting of the unit. The imager has an additional glass window at the bottom of the housing to allow the Alarm and Fault LEDs to be seen from below. Where condensation is expected, both housings can be equipped inside with a heater of minimum 5W. Configuration Options OSID-EHI OSID-EHE Minimum Maximum OSI-10 25m (82ft.) 125m (410ft.)

Anti-Condensation Film for OSID Emitters and EH Housings Application OSID Emitters are equipped with an acrylic lens and are therefore not normally prone to condensation. However in some extremely moist environments, condensation may nevertheless occur on the lens. Slow forming condensation can produce an unacceptably large loss of signal. To prevent that from occurring, the Emitter lens can be fitted with an anti-condensation film. The film can be quickly and easily applied to the lens without the need for special tools or adhesives. Prevents condensation Fast and easy installation Simple maintenance Long lifetime Highly scratch resistant Does not crack, peel or discolour from exposure to sunlight Easy to clean using cleaning solvents The film prevents condensation from forming and keeps the lens clear. Note however that the film causes a 10% reduction in maximum detection distance. A damp cloth can be used to clean the film if it becomes contaminated. The combination of the film and the algorithms in the Imager offer a cost-effective solution for condensation susceptible areas. The OSID Imager has a built-in heater and the film should not be used on Imagers. In harsh environments where the OSID-EH environmental housings are used and condensation is expected, both Emitter and Imager housing can be fitted with an anticondensation film. When applied on Emitter and Imager housing there is a 20% reduction in maximum detection distance.
