Interlogix VE700AM Serie Manual De Instalación página 9

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 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: 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.
