Multibeam alignment and masking
The multifunction lens fitted to the DI601AM detector produces
seven long-range beams and seven medium- to short-range
curtain PIR beams. The PIR circuitry detects changes in heat
and movement in the beam pattern. Items such as trees,
shrubs, ponds, boiler flues, and animals should be considered
when positioning the detector.
The detector module is fitted with two sliding shutters to reduce
the detection angle.
The curtains are fitted to the pan and tilt module as shown in
Figure 6. Each section of the detector lens gives a coverage
pattern of approximately 10 degrees.
An additional set of curtain sliders is provided should the beam
pattern be narrowed even further, e.g. if the minimum detection
angle of 10 degrees is required.
When coverage exceeds the desired detection area, adjust the
module as required and mask off any beams, either vertically or
horizontally, to avoid unwanted detection.
Use portions of the self-adhesive silver mask applied to the rear,
smooth side of the lens as shown in Figures 9 to 12. Gently lift
the top and bottom edges of the pan and tilt module to release
the lens. To replace the lens, please begin by sliding one side of
the lens into the clips on the pan and tilt module. After one side
is secure, do the same for the opposite side. Once both sides
are secure, gently lift the top and bottom edges of the pan and
tilt module and press on the lens to click it into place.
Always replace the lens the correct way up to ensure exact
beam pattern coverage. The top of the lens is marked TOP as
shown in Figure 7. There is a locating notch on the top of the
pan and tilt module that locates into the cut-out on the top of
the lens.
Table 2 below summarizes typical masking configurations for
use when the range option is set to 30 meters.

Figure 13 shows the pattern for the maximum range in the
optimum position (see Figure 9). Masking the top section of the
lens reduces the range to 20 m.
Figure 14 shows the pattern for the minimum range (10 m) In
this case masking the top section of the lens reduces the range
to 6 meters.

Pulse count
Pulse count is the number of times the detector must detect a
presence before signalling an alarm.
When the pulse count is set to 1, the detector is most sensitive.
