Aligning the beam and walk testing the
detector
Aligning using VE710 alignment tool
See Figures 18 and 19.
1.
Insert the VE710 in the sub-frame with the on/off switch
facing the floor.
2.
Connect it to the COM port.
3.
Turn on the VE710.
WARNING:
Do not look into the laser beam.
The output power is less than 1 mW. Consequently the
VE710 laser is classified by IEC60825-1 as a Class
2 laser. The eye's blinking reflex is fast enough to prevent
any permanent damage to the eye.
4.
The laser spot indicates the product alignment (Figure 18).
If this spot on the wall veers from the centre of the desired
detection area 1 m (3.3 ft.) from the ground, then loosen
the base fixation screws (see Figure 4) and use the three
adjustment screws in the base to realign it to the centre,
as shown in Figure 19. When the spot is correctly
realigned, retighten the base fixation screws.
5.
Remove the alignment tool and replace the cover.
6.
Carry out walk test. Make sure that the red LED is On after
walk test.
Aligning without the alignment tool
See Figure 19.
1.
Insert the mirror blinders in order to ensure that the
detector is in single-curtain mode.
2.
Put J2 to On and wait until both LEDs are off.
3.
Walk in front of the detector across the field of view at
normal speed (without pausing) and at the maximum
possible range. When you enter the beam, both LEDs will
start to blink simultaneously.
After crossing the beam, if:
a.
The red LED is On (Figure 20, item 1), the alignment
is OK.
b.
The red and yellow LEDs are blinking simultaneously
then the field of view is obstructed and is insufficient
to verify an alarm.
There are two options:
•
If the blinking started near the end of the detection
area, you need to align the beam to the left (Figure
20, item 2).
•
If the blinking started near the start of the detection
area, you need to align the beam to the right (Figure
20, item 3).
Loosen the base fixation screws (see Figure 4) and use
the three adjustment screws in the base to realign the
beam to the centre, as shown in Figure 20. When the
beam is correctly realigned, retighten the base fixation
screws.
4.
If the LEDs do not blink, the curtain is outside of the
detection range (Figure 20, item 4). Walk across the beam
at a shorter distance to try to detect it.
5.
Redo walk test to confirm that the detector is correctly
aligned.
8 / 50
6.
Put J2 to Off.
Notes
•
If the CLM is on, the alarm output is activated.
•
It is recommended to place the cover on the detector
during the CLM walk test.

General information
Latching
When using multiple detectors in a single loop, wire for
day/night (D/N) and walk test (WT) inputs, as shown in
Figure 6.
Remotely enabling/disabling the walk test LED
See Figure 6.
Disconnect the CV to terminal 10 (D/N) and connect it to
terminal 11. The detector's LED will blink as the alarm relay
opens and closes. The walk test can now be carried out.
Note:
Only enabling the walk test will not clear the alarm
memory. After disarming the system following an alarm, switch
the walk test to On. When you switch walk test to Off, the
indication of memorised alarms will reappear. Only when CV is
re-applied to terminal 10 (i.e., the system is rearmed) will the
memory be cleared and the LEDs turned off.
To enable the walk test LED without a remote CV input, set
DIP switch 4 to the On position. After walk test, set DIP switch
4 to the Off position.
We recommend that the detector is regularly walk tested and
the communication with the control panel checked.
Setting the alarm memory
See Figure 6.
Note:
First set the appropriate active polarity of the control
voltage (CV) using the PIR DIP switch 1.
Connect the CV to terminal 10 when the system is armed.
When the system is disarmed, disconnect the CV. If an alarm
occurs during the armed period, a flashing red LED will
indicate which the detector(s) caused the alarm. Re-applying
the CV (re-arming the system) will reset the LED indication and
memory.
Selecting the coverage pattern
See Figures 21 and 22.
