2–PRODUCT DESCRIPTION
AND INTENDED USE
LP1 and LP2 are metal mass detectors
which use a magnetic loop (loop detector)
and may be used for automatically open-
ing gates, doors, barrier gates, etc.
The model LP1 detector may be connect-
ed with a single loop and has one output,
while model LP2 may be connected with
two loops and has two outputs. The two
outputs may be independent (each loop
commands its own output) or they may be
combined to detect the vehicle’s direction
of movement (see point 3.3 for details).
Both models have an additional alarm out-
put, which is active during regular opera-
tion but is turned off in the event of a failure
or power failure.
3– INSTALLATION
Warnings
•Disconnect the power supply to the
system before performing any instal-
lation operations; if the system is
equipped with a buffer battery, it
must be disconnected.

3.1 –Preliminary checks
Carefully check that the parameters for use correspond to the figures appearing in the
“Technical Features” section. In the event of doubt, do not use the product, and ask the
Nice technical assistance service for clarification.
3.2 –Choice of coil geometry
The loop, constituting the detector’s sensitive element, is an inductor which, in combina-
tion with a condenser in the detection circuit, forms a type LC oscillator. The circuit’s res-
onance frequency depends on the loop inductance value. When a vehicle passes over
the loop, its metal parts (body, wheels, suspensions, etc.) change the inductance value
and therefore the frequency of the oscillator. The detector checks this frequency and
trips the relay when the variation exceeds the threshold specified for the established level
of sensitivity. To improve sensitivity and prevent false switching, it is essential to construct
the loop according to the following simple rules:
01. The rectangular loop is the simplest, most effective shape (fig. 1); it is suitable for
cars, trucks and buses. The 45° shape (fig. 2) is recommended for detecting motor-
cycles and bicycles, while the 8 shape (fig. 3) is for use in applications requiring
reduced sensitivity at the sides, such as when the loop is close to the gate.
02. Loop size must not exceed the size of the object to be detected; for instance, if the
car to be detected has an average width of 2 m, the loop must be 2 m wide.
03. If the loop is located near the gate or other moving metal parts, it is important to
comply with the minimum distance of 1 m between the loop and the moving parts.
04. Fixed metal parts close to the loop (such as concrete reinforcements, streetlight
poles, etc.) may reduce the detector’s sensitivity; make sure that this cannot hap-
pen by moving these parts, as a variation could result in false tripping.

EN
4- English
05. Install the LP1 or LP2 detector as close to the loop as possible; if possible, less than
10 m away. The cables connecting the loop must be kept separate from the power
cables and the output cables.
06. The loop may be made of ordinary insulated copper wire, preferably measuring 1.5
mm2.
07. The two wires at the start and end of the loop must be wound around themselves at
least 20 times per meter (fig. 4).
3.3 –Detecting direction of travel (LP2 only)
Detector LP2 may be connected with 2 separate loops, which may activate 2 completely
independent outputs, or, with appropriate programming, be used to determine direction
of travel.
Direction 1 ]2
If loop 1 is engaged first, when loop 2 is also engaged output 1 is triggered, remaining
active until loop 1 is no longer engaged. Loop 2 will never be triggered.

Direction 1 \2
If loop 2 is engaged first, when loop 1 is also engaged output 2 is triggered, remaining
active until loop 2 is no longer engaged. Loop 1 will never be triggered.
To obtain this function, both loops must be triggered, at least for a short time (fig. 5).
3.4 –Loop construction
01. After determining the position and geometry of the loop, a groove must be made in
the floor 5-8 mm wide and at least 30 mm deep; greater depths are required if the
installation surface is unstable and flexible under pressure; in asphalt for instance,
the cable requires greater protection because the deformation could damage it with
time. A 45° cut of the corners of the loop is recommended to improve mechanical
protection of the wire.
02. Clean the groove thoroughly then insert the wire, pressing it down as much as pos-
sible so that it settles towards the bottom.
03. The number of turns to make with the cable to produce the loop depends on its cir-
cumference; see Table 1.
The figures shown in the table are for cement or asphalt pavement; the presence of
metal reinforcement rods in the pavement will change the loop’s inductance. If you

have any doubts regarding the loop you have made, measure inductance before
proceeding, as described in section “6 – Simulations and checks”. The loop is cor-
rect if inductance is between 80 and 300 µH.
04. To protect the loop against mechanical stress, it may be useful to insert a cord of
string or plastic in the groove. Seal the groove with bitumen or resin for outdoor use.
Pay attention to sealant temperature: it must not exceed the maximum temperature
for the electrical wire in the loop, which is normally 70°C.
05. Fig. 6 shows the correct loop composition.
4–PROGRAMMING
The programs described in this section refer to the LP1 with one loop. On the LP2 pro-
gramming of the second loop is available in sequence after the first loop.
Programming takes place using key P1 (Mode) which allows you to scroll through the
various functions available (on the LP2, first those for loop 1 and then those for loop 2).
Once you have reached a function, you may use P2 (Level) to choose the “value” to be
assigned to the function. Both lists of functions and values are “circular lists”; when the
list reaches its end, it starts scrolling from the beginning again.

4 - Sensitivity: allows you to select the sensitivity of the reading, between 1 (not very sen-
sitive) and 9 (very sensitive). The regulation range may be reduced as a result of use of giv-
en frequencies or in the case of very low loop inductance (few turns).
5 - Automatic sensitivity: “automatic sensitivity” is normally turned on to permit correct
detection of truck trailers along their entire length, as the front part (driver’s cabin) is rela-
tively close to the ground and easy to detect while the trailer is higher and hard to detect
without greater sensitivity.
6 - Frequency: to prevent interference between nearby detectors, it is possible to change
the frequency band; frequency may be modified within the following limits of Table 7.
7 - Direction logic: when detection of the “direction of travel” is activated (on LP2 only), it
is possible that detection may take place in both directions or in just one direction.
8 - Configure Out 2: If loop 2 is turned off, you may turn off the corresponding output.
9 - Power failure: used to turn on protection against power failures. This function saves
the present conditions before the power cuts out. When the power supply returns, the
detector compares the saved information and activates the outputs according to whether
the loop is active or not.
If this function is not active, the detector will be “recalibrated” when it comes back on,
acquiring data at that specific moment in time.

This function can only be used if the “Basic function” is set to “Barriers” or to “Inverted”, or
the “Time function” is set to “Infinite”. Sensitivity levels can only be controlled between 1
and 5. Lastly, function “5-Automatic sensitivity” must be disabled.
5–DELETING PROGRAMMING AND RECALIBRATING
It is possible to delete all the programming and reset the detector to the factor settings.
Total delete: hold the P1 and P2 keys down for at least 8 seconds.
If changes are made to the environment around the loops, it may be useful to recalibrate it.
Recalibration: press P1 for at least 2 seconds.
6–SIMULATIONS AND VERIFICATIONS
The detectors have a simulation mode which permits activation of various outputs and
measurement of loop inductance. In “simulation” mode the loops must be properly con-
nected.
To turn on “simulation” mode, hold the P1 and P2 keys down for at least 2 seconds. As
during programming, you may then press P1 to scroll among different types of simulation;
select the value to be simulated while holding P2 down; refer to the Table 8.
Both lists of functions and values are “circular lists”; when the list reaches its end, it starts
scrolling from the beginning again. To exit simulation mode, hold P1 down for at least 2
seconds.
