1) INTRODUCTION
The SPS MULTISCAN++PK gas detection system for car parks is made up of the
MULTISCAN++PK control panel (in four versions 32, 64, 128 or 256 according to the number of
connectible gas detectors) and SMART-P detectors, specifically designed to meet EN50545-1
European standards. Other detectors can be connects (i.e.: Sensitron Smart3 NC) with 4-20 mA
output via 8-input ST.G/IN 8 PK modules.
Detectors can be addressable (Smart P) and thus directly connectible in buss, or 4-20 mA
analogue type, connectible via 8-input remote STG/IN8-PK modules.
The unit allows for three alarm thresholds to be set for each detector. The alarm threshold
activation mode changes according to the type of gas detection profile and connected detector:
There are two alarm threshold modes: Average thresholds and Real-time (Fixed) thresholds.
For the LEL Profile (for explosive gas detectors), only real-time thresholds can be set.
For the Toxic Park Profile, both real-time and average thresholds can be set.
For the Toxic Park EN50545-1 Profile, only average thresholds can be set.
System architecture also includes 8 on-board machine relays and the potential to expand
outputs up to 512 using remote STG/OUT16-S modules and 8-relay boards.
The unit is inserted in a plastic box complete with 27 Vdc 4 A power supply.

MT3394E Rev.2 15/10/2019 Pagina 8 di 55
2.2) Gas detectors installation
At the mounting and installation phase be sure all safety precautions have been
considered.
Always consider how important it is the correct positioning of gas detectors to get the
optimum response. Be careful never to install gas detectors close to air intakes or fans
causing strong air currents.
Be sure the detectors are attached to a firm base to prevent vibration that can damage
them, producing unreliable results.
Although the electronics comply with the electromagnetic compatibility rules, it is
advised to keep the detectors at a distance from any radio frequency senders (such as
radio links or similar).
Please be also sure that detectors are placed in a convenient location for future
maintenance and calibration requirements.
We recommend you mount the Smart P detector at nose level (about 150 cm off the ground)
since this is the position suited to detect CO and NO2. The Petrol Vapour detector should, on
the other hand, be installed about 30 cm off the ground. the CO+PETROL VAPOUR detector
comes with an extension kit to mount the Petrol Vapour sensor 30 cm off the ground.
Also remember that correct detector positioning is essential to ensure prompt and accurate
detection.
The gas detector is always to be mounted with the sensing element placed downward.
For no reasons at all the enclosure can be drilled.
Wall mount the detectors by employing the existing holes

2.4) Electric wiring
The connection of the detectors to RS485 bus lines should be performed by using a 4-wire
cable, 1 pair for the RS485 bus and 1 for the power supply.
Wiring between the detectors and the control panel should be made by using connection cable
EIA RS485: 2 core wires with section 0.22 / 0.35 mm2 and shield (twisted pair). Nominal
capacity between the wires <50pF/m, nominal impedance 120 ohm.
These features can be found in BELDEN cable 9842 or similar (data transmission cable in EIA
RS485).
Using this wiring, the total length of the line should not exceed m 1000.
Detectors and output modules are to be wired in daisy chain mode. We recommend avoiding
star or tree mode connection as interference immunity would be reduced.
Make sure that a 120 Ohm end line resistor is placed at the beginning and at the end (on the
last detector or output module) of the bus line.
For the detectors' power supply connection we recommend to use a 2-wire cable with suitable
section according to the distance and number of detectors.
Once the installation has been completed, verify that each detector reaches at least 12 Vdc.
Each Smart P detector connected on the unit line must have a univocal address. Use the
specific STS/CKD PK keypad to set the detector address. See the specific paragraph below in
the manual.

2.5) Detector power ON
When the detector is powered on, the green LED DL1 on the motherboard starts
blinking at slow intermittence.
After nearly two minutes, the red LED flash rate is equivalent to the detector working
status (see table below).
Once the warm-up phase is over, the detector can work correctly, although the optimal
performances will be achieved after two hours.
2.6) Testing and Use
Detectors are factory calibrated for the specific gas required by the customers. Future
adjustment of the preset calibration can be carried out by employing the calibration keypad.
Testing should be carried out by using a gas mixture in the appropriate range, along with our
calibration kit.
The green DL1 LED on the electronic board flashes to indicate detector status as illustrated in
the table below.

2.7) Handheld calibration keypad ST.S/CKD PK
Smart P gas detectors offer a field adjustment for the Zero, Span (response to gas) and the
serial address (for the RS485 bus).
By operating with the handheld calibration keypad, pressing ENTER, ESC, Arrow UP and Arrow
DOWN, the Zero, Span and serial Address shall be accomplished.
The keypad can be connected when the detector is powered ON and operating. Before opening
the detector enclosure, be sure all safety precautions have been considered.
Insert the female connector of the keypad at the edge of the flat cable into the male connector
on the Smart P main board.
Once connected, the keypad will display the gas concentration being measured.

MT3394E Rev.2 15/10/2019 Pagina 12 di 55
Adjustments are required whenever either Fault or unjustified Alarms due to environmental
conditions occur (Zero adjustment) or detectors need modifying their response to gas (Span
adjustment).
Span adjustment requires a calibrated gas cylinder, either filled with the same gas the detector
has been calibrated for or a reference gas advised by the manufacturer
For the Zero adjustment, gas detectors are to be in fresh air (without any gas or interfering
compounds) and powered on since 8 hours at least.
Once the routine is over a test with gas is to be made to verify the right working condition.

ZERO
When the detector SMART P is turned On for the first time, or when a new kit sensor is
mounted into the instrument, the AUTO ZERO calibration is recommended. This action
has to be done under the following two conditions:
Gas detectors are to be in fresh air (without any gas or interfering compounds) and
powered on since 8 hours at least. Where there is no such certainty of being in clean air
(without gas), calibration Auto zero is necessary to use a special mixture of synthetic air
(79% nitrogen and 20.9% oxygen).
Once the routine is over a test with gas is to be made to verify the right working
condition.
Perform the task of Auto Zero Smart P detector simply by pressing ENT from Auto Zero
menu and follow the steps in the block diagram.
SPAN
The Span allows the instrument calibration and is to be executed if when tested in gas occurred
that the instrument is not properly calibrated. To run the Span is essential the use of a mixture
(cylinder) gas sample with the Target Gases (gas that the tool should detect) or with a reference
gas to which the sensor is sensitive.
To apply the mixture of gases sample at Smart P, Sensitron makes available a dedicated
calibration kit. The calibration KIT, supplied with a carrying case, comprises the necessary
instrumentation to verify in situ the response of Sensitron's gas detectors The calibration cap
can be fitted on all of Sensitron sensing heads by employing, when necessary, the endowed
adaptors.

MT3394E Rev.2 15/10/2019 Pagina 14 di 55
Both gaskets and screw threads inside the cap allow an optimum tightness between the sensing
head and the cap. The analysis chamber inside the calibration cap has been designed and
realized to obtain a test method identical to that adopted in our laboratory for the initial factory
calibration.
The valve complete with flow meter is to be mounted on the gas can to allow a gas outlet at a
controlled velocity to obtain accurate data to verify the sensing element status.

Disconnect the two wires that lead from the unit board (JP47 and JP51 connectors) to the
bottom of the box for power connections (see fig. 3.4.1). Close the front panel turning the lock to
LOCK.
Remove the 4 screws at the 4 corners of the box and remove the front part of the unit box.
Holes can now be drilled in the back of the box for wire passage.
We recommend you use an IP65 wire clamp at wire entrance to maintain the same protection
level as the unit.
Secure the back of the unit to the wall using the holes (D) or by the enclosed brakets.
