Essential Info

Visonic's SRN-2000 is the world's most flexible and reliable dual-element, low-noise, pyro-electric PIR detector. Visonic is a leader in the field of passive infrared detection devices, and continues to develop lens technology to satisfy the expanding needs and demands of the security industry. As the only PIR manufacturer in the world to produce its own Fresnel lens assemblies Visonic offers an outstanding variety of 45 easy-to-change lenses - more than the entire combined industry competition. Visonic's noted Super-Red Lens Library, and the state-of-the-art detection technologies are backed by 30 years of Visonic expertise. This unit includes is a perfect add-on for any hardwired security/alarm system. Monitor upward-looking zones for ceilings, stairs, and odd shaped rooms, as well as long corridors or 2-3 rooms, all from this one PIR detector. Maximum coverage, using the wide angle lens, is 60ft x 60ft (18m x 18m). This universal PIR, with select lens combinations, creates the highest performance in all respects: sensitivity, reliability and false alarm immunity.

A unique "test point" can be used for pinpoint adjustments of the detection pattern as well as for locating background interferences. Special lens masking material is provided to enable masking detection zones exposed to interfering sources, such as cold and hot air ducts or outlets, moving objects, etc.


More Info

The SRN-2000 series of passive infrared detectors presents a technological break-through that is revolutionizing the PIR industry. The SRN-2000 employs an innovative approach by combining several different design techniques to solve the industry's biggest problem - false alarms. By incorporating the following programmable features, the SRN-2000 truly masters the false alarm problem. Programmable to suit different applications, the pulse counter is used to virtually eliminate environmental disturbances. Adjustable coverage range allows you to adjust the coverage to fit different room sizes. The unprecedented RF immunity provided rejects RF interference up to 2000 MHz. The Light rejection filter will reject visible light variations, which sometimes cause interference. Masked lens patterns are used to block thermal disturbances. Test points identify and eliminate background disturbances. Dual-element, low-noise, pyro-electric detectors reject thermal variations with maximum signal to noise ratio. An outstanding variety of 45 easy-to-change lenses are available to save time and money, also to provide the best coverage pattern for any installation.

RED LENS LIBRARY is divided into the following nine sections. The lens's you use will be determined by location of the PIR and the type of motion you intend to monitor.

  • Corner Mounting Wide-Angle 90° - 100° : This section comprises 6 lenses which provide the maximum room coverage, when the PIR is installed in the corner
  • Ultra-Wide-Angle 120° - 140° :This section comprises 3 lenses which provide the largest and widest room coverage in applications where the PIR is wall mounted or flush mounted.
  • Pet-Alleys : This section comprises 6 lenses with a single horizontal beam layer which allows pets to move under the coverage pattern, undetected.
  • Long-Range Corridors up to 36 m (120 ft) : This section comprises 3 lenses specially designed for long range and narrow areas such as corridors, aisles and long walls.
  • Multiple Room and Corridor Coverage : This section comprises 10 lenses, each providing a combination coverage of one or two Long-Range corridors and one or two Wide-Angle rooms simultaneously, using a single PIR.
  • Combined Ceiling, Stair and Room Coverage :This section comprises 8 lenses providing multiple coverage of ceiling
    and stairs in addition to the normal room area coverage.
  • Finger Curtains : This section comprises 3 lenses providing coverage of multiple vertical finger curtains which may be used to prevent access from two walls simultaneously and detect movement through curtains located in the area between the walls.
  • Lenses for Energy Management PIRs : This section comprises 4 high density lenses specially designed for use with models SRN-2000E, ET and EF in Energy Management applications
  • Solid Curtain PlRs : This section comprises 5 lenses specially designed for models SRN-2000H and SRN-2000CH, providing various types of solid curtain coverage.
