LENS LIBRARY

SUPER-RED offers a selection of more than 45 lenses to provide the
best coverage pattern for any installation. The SUPER-RED LENS
LIBRARY is divided into the following nine sections:

Section 1: 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.

Section 2: 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.

Section 3: Pet-Alleys.
This section comprises 6 lenses with a single horizontal beam layer
which allows pets to move under the coverage pattern, undetected.

Section 4: 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.

Section 5: 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 Wide­Angle rooms simultaneously, using a single PIR.

Section 6: 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.

Section 7: 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.

Section 8: 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.

Section 9: Solid Curtain PlRs.
This section comprises 5 lenses specially designed for models SRN-2000H
and SRN-2000CH, providing various types of solid curtain coverage.

3.3. SRN-2000H Solid Curtain PIR

Description
The SRN-2000H is a horizontally mounted PIR which provides a

variety of Solid-Curtain coverages. The unit may be used to provide
wall and large show window coverage or as an internal invisible
barrier to detect movement between two areas. Lens No. 52 is the
standard lens supplied with SRN-2000H.
Fitted with lens No. 52 this unit produces a solid curtain coverage
extending out from the mounting wall to the opposite wall - up to a
maximum of 18 m (60 ft) and down to the floor (Fig. 3).

Figure 3. Curtain Coverage -

Lens No. 52

Figure 4. Pet-Alley Curtain -

Lens No. 52

A Pet-Alley curtain is created by installing the SRN-2000H near the
floor and angling it 45° towards the ceiling. The height of the curtain
can be adjusted precisely by rotating the lens.

In addition to lens No. 52, several interchangeable lenses are offered,
providing coverage combinations of solid curtains and beams. For
more details refer to SUPER RED LENS LIBRARY.

Mounting

The SRN-2000H should be mounted horizontally on its angular shaped
back, pointing to the floor at a declination of 45°.

The preferred location is at the wall­to-ceiling juncture. Wall or ceiling
mounting is also possible as long as
the 45° angle is maintained (Fig. 5).

The unit can be mounted at any
height up to 18 m (60 ft), providing
the largest curtain coverage on the
market - 18 x 18 m (60 x 60 ft). All
lenses, except for No. 52, require
mounting the unit with the lens to the
left (when facing the unit).

Adjustment

The curtain coverage can be adjusted 10° left or right by sliding the
printed circuit board against the graduated scale. Vertical adjustment of
±15° is provided by rotating the lens (applicable for lens No. 52 and 56
only). In other regards, the SRN-2000H is virtually identical to the SRN-

2020.

3.4 SRN-2000R Ceiling Mounted PIR

The SRN-2000R is a ceiling
mounted PIR.

Fitted with lens No. 55, the unit
produces four finger curtains
projected from the ceiling, down to
the floor.

When mounted at the height of
3 m (10 ft), the unit provides a

pattern of 3 x 9 m (10 x 30 ft)

SRN-2000R Coverage Pattern

maximum (measured at floor level). The maximum recommended
mounting height is 6 m (20 ft) providing a floor coverage area of 6 x
18 m (20 x 60 ft) maximum.

In all other regards, the SRN-2000R is virtually identical with the
SRN-2000H.

3.5 Changing Lenses

To change or adjust a lens, release and remove lens retainers located
on both sides of the lens by pushing them from the inner side of cover
(Fig. 7). Insert a new lens with the grooved surface facing out and the
lens number in the upper right corner.

From inside the cover, carefully center the lens by sliding it right or left,
until it edges protrude equally at both sides.

Holding the lens firmly in place, insert the lens retainers from the front
(ridges pointed outward) and firmly push them into place until a click
is heard (Fig. 8).

4. INSTALLATION

4.1. Selecting the Mounting Location

A SUPER RED passive infrared detector can be mounted directly onto
the wall (surface mounted), or in a corner. It may also be flush mounted,
using optional flush mounting bracket SRF-201 (Fig. 9). Always mount
the unit on a firm and stable surface.

A. Select the mounting location so that the expected motion of an

intruder will cross the beams of the coverage pattern provided by
the lens in actual use.

It is recommended to aim the PIR detector toward the coolest place

in the protected area, in order to obtain the maximum sensitivity
where high ambient temperatures are expected.

B. Select the most convenient

mounting height.

You may mount the unit anywhere

from ground level up to 5 m (17 ft).
An accurate adjustment table deter­mines the recommended angle for
any combination of range and
mounting height (see Table 1).
Take into account that installations
at increased height result in larger
blind areas close to the detector.
