• Complete any wiring dressing to minimize movement to the

detector once the alignment procedure is completed.

• Insure that the appropriate number of reflectors are

used  for  the  installed  distance.  Distances  between  230
&  328  Feet  (70  -  100m)  require  additional  reflectors  (4
total).  The  BEAMLRK  accessory  should  be  used  in  these
cases.

• Insure that the line of sight between the detector and

reflector is clear and that reflective objects are not too
near. See mounting Instructions for more details.

• Insure that both the detector and reflector are mounted

within their operational parameters for off axis angles.
See Mounting Instructions for more details.

• Disable the zone or system to prevent unwanted alarms

before applying power.

• Insure power to the detector is “ON”.

You are now ready to begin the alignment procedure.

Step 1. Coarse Alignment

Refer to Figures 11 and 12 for this step.

1. Insure that both of the optics lock-down screws are loos-

ened so that the optics will move feely.

2. Looking through the alignment mirror at both the align-

ment  sight  and  reflector  simultaneously  locate  the  posi-
tion  of  the  reflector  in  the  optical  sight.  This  step  will
require  some  practice.  It  is  necessary  to  train  your  eyes
to  shift  focus  between  the  reflector  and  the  mirror  in
order  to  locate  the  reflector.  If  the  distance  between  the
reflector  and  the  detector  is  large  it  is  helpful  to  place  a
brightly  colored  object  on  the  wall  near  the  reflector  to
aide in seeing the reflector in the alignment mirror.

3. Once the reflector has been located, begin to adjust both

the  horizontal  and  vertical  alignment  knobs  so  that  the
reflector  becomes  centered  in  the  alignment  mirror. Take
care  in  this  step.  If  the  optics  are  incorrectly  aligned  in
this  step,  it  will  not  be  possible  to  proceed  with  the  fine
adjustment step.

Step 2. Fine Adjustment

Refer to figures 10 through 12 for this step.

In  this  step  you  will  be  fine-tuning  the  optics  to  the  reflec-
tor. To  provide  feedback  of  the  signal  level  coming  from  the
reflector  the  dual  digital  display  readout  will  be  used.  Due
to  the  large  distance  range  that  the  detector  can  operate
over it is necessary that the detector operate with many dif-
ferent  settings  of  “electronic  amplifier  gain”.  The  detector
is  capable  of  determining  the  appropriate  gain  setting  and
then  setting  it  itself  via  on-board  processing  algorithms.
There  are  no  external  gain  settings  on  the  detector  that
must  be  set  by  the  operator.  Periodically  throughout  the
fine  adjustment  step  the  detector  will  need  to  re-adjust  its

“electronic  amplifier  gain”  setting.  When  this  occurs  it  will
be  indicated  by  the  dual  digital  readout  as “-  -”.  When  this
occurs,  cease  any  further  adjustment  until  the  display  again
reads a number value.

1. Insure that neither you nor any other objects are in the

line of sight between the detector and the reflector.

2. Depress the Alignment switch once. Both the digital dis-

play  and  the  yellow  LED  should  turn  on  indicating  that
alignment  mode  has  been  entered.  The  display  should
begin  reading  “-  -”  signifying  an  electronic  gain  adjust-
ment.  After  a  few  moments  the  display  will  indicate  a
numeric  value  near  20.  If  the  display  reads  “Lo”  then
the detector is not receiving enough light from the reflec-
tor.  Go  back  and  repeat  the  coarse  alignment  step  and
verify that the proper number of reflectors is used for the
installed distance.

Note: The display will continue to read “Lo” until the

detector receives enough light from the reflector to
continue with the fine adjustment step.

Note: In alignment mode (indicated by the yellow LED

and the numeric display) the sensitivity select and
test switches are disabled.

3. With the display reading a numeric value, begin adjust-

ing  the  horizontal  and  vertical  alignment  knobs  one  at
a  time  in  the  direction  that  increases  the  numeric  signal
level  on  the  display.  Continue  adjusting  each  axis  one
at  a  time  going  back  and  forth  between  them  until  a
peak  value  is  indicated.  If  a  value  of  90  is  achieved,  the
detector  will  re-adjust  the  electronic  gain  once  again.
This  will  be  indicated  by  a  “-  -”  reading  on  the  display.
When  this  happens  halt  any  further  adjustment  until  the
display  again  reads  a  numeric  value.  This  process  may
occur more than once during the fine adjustment step.

Note: Each time the display reads a value of 90 or greater

the detector will reduce the electronic gain. Each
time the display reads a value of 10 or less the
detector will increase the electronic gain.

4. Once satisfied that it is not possible to achieve a higher

reading  on  the  display,  depress  the  alignment  switch  to
complete  the  fine  adjustment  step.  The  digital  display
readout  will  turn  “OFF”  and  the  yellow  LED  will  remain
“ON”.

Note: It may not be possible to achieve a value near 90 on

the  display  during  the  last  adjustment  iteration.  The
final  value  of  the  display  will  not  likely  be  near  90.
This  is  normal.  It  is  due  to  the  detector  reducing  its
