  • Page 5: Introduction

    The SPS MULTISCAN++PK gas detection system for car parks is made up of the MULTISCAN++16-PK control panel 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 module.

  • Page 6: Smart P Gas Detectors

    SMART P GAS DETECTORS SMART P gas detectors come in the following versions based on the type of gas to be detected: CO, range 0-300 ppm, 3 pin industrial cell NO2, range 0-30 ppm, 3 pin industrial cell Detectors with dual sensor were manufactured to optimise installation costs, coupled with the CO-NO2 and CO-PETROL VAPOUR sensor in a single case.

    2.2) Detector 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.

  • Page 10: Electric Wiring

    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).

  • Page 11: Detector Power On

    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.
  • Page 12 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.

    9841 or similar wire (EIA RS485 data transmission wire). Only connect detectors (and IN and OUT modules) in cascade. Avoid tree or delta connection since they reduce interference immunity. -) Detector power supply (and IN and OUT modules on the bus) must be connected with a 2- core wire with adequate section based on the number of connected devices, their distance from the power supply and each device’s consumption (please see the technical manual enclosed with gas detectors for this purpose).
  • Page 24 Detectors with 4-20mA output Detectors with 4-20mA analog output are connected to the unit via remote 8-input modules STG/IN8-PK. The modules are connected on the panel's bus to be field mounted far from the control panel. A 4-20mA transmitter requires a 3-core wire for connections: 2 wires for power supply (usually 12 to 28 Vdc but refer to the gas detector technical manual) and one wire for the 4-20mA signal.
  • Page 25 Detectors with RS485 output (only Smart P version) Detectors with RS485 digital outputs are directly connected to the RS485 bus. 4 wires are required in this type of connection: 2 for the RS485 serial bus and 2 for device power supply. For this reason we suggest you use two different wires or a single wire with suitable features as described below.
