* Factory default
DIP Switch 1: When to signal AM (anti-masking) or TF
(technical fault) output
On: Signals AM or TF only when the system is in day mode.
EN 50131-2-2 compliant.
Off: Always signal AM or TF.
Note: To prevent AM alarms during night mode, the following
DIP switch settings are recommended:
1: On, 2: Off, 3: Off, 4: Off
AM alarms are now only signaled to the control panel during
day mode by the AM relay. The LEDs are controlled by
day/night and walk test inputs. Resetting the AM alarm can
only be done in walk test mode.
Never show the detector state to the intruder via the LEDs.
DIP Switch 2: AM sensitivity
On: Selects a higher level of AM sensitivity. AM relay reacts
within 6 seconds.
Off: Selects the standard AM sensitivity. AM relay reacts within
12 seconds.
DIP Switch 3: Resetting the AM/TF output
The VE700AM will only reset an AM alarm if it has ensured
that the cause of the AM alarm has been removed. If the AM
circuitry cannot return to its original reference levels, then
either the detector is still masked or has possibly been
damaged. The owner should then visually check that the
detector is still fully functional.
On: After a 40-second inhibit period, resets the AM or TF
status when a PIR alarm is generated.
Off: Resets the AM or TF status after a PIR alarm, when the
system is set into day and walk test status. The yellow LED will
blink quickly. When the system is in night mode, the yellow
LED will turn off and the system is reset.
DIP Switch 4: How to signal AM or TF output
On: Signals AM on both the AM and alarm relays. Signals TF
on the AM relay only.
Off: Signals AM and TF on the AM relay.

Testing the anti-masking functionality
AM start-up sequence: When the VE700AM is powered, the
AM circuitry will wait until the cover of the detector is properly
mounted.
As soon as the cover is mounted, the AM circuitry will monitor
the housing and the surrounding area and store the received
signal levels as reference levels. This procedure takes
75 seconds. During this period, the surrounding area should
remain clear from movement and objects temporarily placed
within 50 cm of the detector.
To test the anti-masking ensure that the PIR DIP switch 4 is
Alarm
set to ON (LED on) and then hold your hand approximately
10 cm (4 in.) in front of the detector for 12 seconds (when
using standard sensitivity) or for 6 seconds (when using high
sensitivity). The yellow LED will light accordingly.
Aligning the beam and walk testing the
detector
Aligning using VE710 alignment tool
Note: VE710 laser alignment tool has not been evaluated by
UL.
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:
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.
Do not look into the laser beam.
