The Multiscan++Park are gas control panels designed to meet with the new European Standard prEN50545-1 for the toxic gas detection in the car parks.
As written in the first chapter of the standard, the scoop is "intended to control a ventilation system and [...] to warn of a toxic hazard".
Behind the scope of this standard, there is a double intend: from one side, the demand for an increased safety of gas detection system in car parks that prevents inadequate or unsafe systems from being used or installed. The other scope of this standard stresses the importance of creating a system respectful of the energy saving policies the EU committed to: the large waste of energy of ongoing ventilation system in car parks is a key point this new standard has undertaken to survey.
To reach this goal, the standard requires adopting time weighted averages (TWA) before triggering the ventilation system. Besides the above, the standard clearly details very demanding requirements to be satisfied, with detectors assuring a very high accuracy and very short polling and response time.
The control panels can manage and monitor up to 128 gas detectors. These can either be addressable detectors, daisy chained on the available loops, or analogue type with 4-20mA transmission, connected via remote 8 inputs cards STG.IN8-PK.
Three alarm thresholds can be set for each gas detectors being connected and the panels allow alarms to the time averaged in a period adjustable from 5 to 60 minutes for thresholds 1 and 2; for the third threshold, alarm is to be triggered between 1 to 5 minutes.
The panels come complete with 8 preset relays on-board the units. The system architecture also allows having outputs extended up to 128 via remote 16 output cards STG/OUT16-S with freely programmable Open Collectors. 8-relays boards have been designed to be connected to STG/OUT16-S modules, should relay outputs be required instead of O/C.
Modules and detectors connectable to this system are:
- 8 Inputs Module STG/IN8-PK with 8 analog 4-20mA inputs.
- 16 Outputs Module STG/OUT16-S with 16 Open Collector outputs.
- 8 Relay Module STG/8REL module to be connected to STG/OUT16-S modules.
- Gas detectors: SMART3-P1, SMART3-P2 and SMART3-NC
The STMTS/PK128-B control panel is delivered in a metal box complete with power supply.
