Step 5: Refit front cover
1. Make sure the internal gasket is fitted
correctly.
2. IMPORTANT: Force the top edge of the cover
behind the two tabs located along the top
edge of the mounting base, so that the hinge
on the cover engages into the slot in the
mounting base.
3. Close the cover, making sure the side tabs
engage correctly.
4. Refit the front screw.
Step 6: Perform a walk test
From the Installer menu, choose
Test, Walk Test to
check that the detector is aligned correctly.
Masking
You can mask off areas you do not want to
monitor using the sliding curtains or masking
sticker, as described next.
Sliding curtains
The detector module is fitted with two sliding
curtains, which you can use to reduce the
detection angle. An additional set of curtains is
provided should the detection angle need to be
reduced further.
The curtains are fitted as shown in Figure 6. Each
section of the detector lens gives a detection
pattern of approximately 10 degrees.
Figure 6. Fitting the curtains
Masking sticker
You can use the self-adhesive sticker in addition
to, or instead of, the curtains. To use the sticker:
1. Study carefully how the lens fits into the
frames - you will need to make sure it is
refitted in exactly the same way.
2. Remove the lens by hand from the front. Do
not use tools.
3. Cut portions from the sticker and apply them
to the rear (smooth) side of the lens.
4. Refit the lens, making sure it is fitted
correctly into the frames and the correct way
up (the top of the lens has a small notch).
CAUTION: Do not put pressure on the
wireless PCB, otherwise damage may result.

To view current settings
1. Press the button once to access the range
option, or twice for pulse count.
2. Count the number of rapid flashes of the
LED. One set of flashes indicates the first
setting in the above table is being used, two
sets indicates the second setting, and three
the third (if applicable).
3. Wait for a second or two (do not press the
button) until you see a double-flash. This
signals end of programming mode.
To change a setting
Repeat the above process many times until you
are confident that you know how to access each
option and determine its current setting. When
you are ready to change a setting, repeat the
