Xtralis VESDA OSE-HPW OSID Open Area Line Smoke Detector Emitter 24 VDC

Open-area Smoke Imaging Detection (OSID) provides 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.

Key Features
  • Maximum detection range of 150 m (492 ft) for the OSI-10
  • Maximum detection range for CPR approved products is 200 m (656 ft)
  • Dual wavelength LED-based smoke detection
  • Optical imaging with CMOS imaging chip
  • On-board event log for fault and alarm diagnostics
  • High tolerance to false alarm due to building movement
  • High tolerance to transient dust, steam and intrusion of solid objects
  • Easy alignment with large adjustment and viewing angles
  • No need for precise alignment
  • Tolerant of alignment drift
  • Automatic commissioning in under ten minutes
  • Simple DIP switch configuration
  • Simple and easy maintenance requirements
  • Three selectable alarm thresholds
  • Status LEDs for Fire, Trouble and Power
  • Conventional alarm interface for straightforward fire system integration
3-D Volumetric Coverage

A significant benefit of OSID is its ability to provide volumetric coverage. As many as seven emitters can be placed within the field of view of a single imager, each placed at different heights. The OSID imager's large viewing angles, both horizontal and vertical, enable three-dimensional area coverage for design flexibility and additional deployment savings. Unlike other volumetric technologies, OSID delivers absolute calibration for consistent detection performance regardless of lighting conditions, smoke colour, airflows or other environmental conditions.

Applications
  • Airports
  • Train stations
  • Shopping Malls
  • Stadiums
  • Hotels & Convention Centres
  • Office buildings
  • Entertainment Venues
  • Warehouses and Production Floors
Open-area Smoke Imaging Detection (OSID) is a new innovation in projected line 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 solves typical line detection problems such as false alarms and targeting difficulties.

Unique Detection Technology
  • The OSID system measures the level of smoke entering light beams projected over a protected area. A single OSID receiver can detect up to seven transmitters 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 synchronized with the image and allow for the rejection of unwanted light sources.
  • By using two wavelengths to detect particles, the system can distinguish between particle sizes. The shorter UV wavelength interacts strongly with both small and large particles while the longer IR wavelength is only affected by larger particles. Dual wavelength loss measurements allow the detector to achieve repeatable measurements of smoke obscuration, while rejecting dust particles or solid intrusions.
Optical Imaging with a CMOS Chip
  • An optical imaging array in the OSID receiver provides the detector with a wide viewing angle to locate and track multiple transmitters. Consequently, the system can withstand a much less precise installation and can compensate for 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 light levels.
Operation
  • Status information (fire alarm, trouble, and power) is communicated through the camera via status LEDs, dedicated fault and alarm relays, and the remote indicator interface. Specific problem (fault) conditions are identified by coded flashes on the LED.
  • An internal heating option is also provided on the receiver to prevent condensation on the optical surface, and a reset input allows for an external signal to reset the unit.
Installation and Maintenance
  • The OSID system consists of up to seven transmitters, for the 90° imaging unit, positioned along the perimeter of the protected area, and a monitor mounted opposite. Each component can be mounted directly to the surface or can be attached using the supplied mounting brackets.
  • On the receiver, a termination board provides all connections and DIP switches allow the user to configure the detector for specific applications.
  • Alignment of the emitter is achieved simply by using a laser alignment tool to rotate the optical spheres until the laser beam projected from the alignment tool is close to the image.
  • The receiver is aligned in a similar way so that its field of view (FOV) encompasses all emitters. A problem or error will be indicated if a transmitter is missing or outside the field of view.
  • The OSID system is very tolerant of dust and dirt and requires little maintenance in practice. Preventive maintenance is limited to occasionally cleaning the optical surfaces of the detector.
