At the core of the control panel is a powerful 8 bit microprocessor operating at a frequency of 12 MHz. MULTISCAN LIGHT version has been designed to manage up to 104 detectors (analogue type, 4-20mA output) while the version PARKING can manage up to 200 detectors. The connection to the detectors is carried out by employing remote modules each offering a 8 input connection linked on the RS485 buses MULTISCAN central units are equipped with 4 output relays programmable and linked to thresholds alarm or fault status, with stable, latched or pulsed output. In addition to these outputs, it is possible to connect 4 output modules on each RS 485 bus so as to offer 64 additional Open Collector output to the version LIGHT and 128 to the PARKING. The flexibility of the control unit permits to use together detector for explosive and toxic gas, by setting different thresholds for every detector. It’s possible to assign measure unit in % LEL for explosive gases and in ppm (part per million) for toxic gases. Both versions MTSL and MTSP are provided with events log: the number of events that the control unit can store is up to 800. A Centronic’s parallel printer port is also available. The system configuration is carried out directly through the keypad on the front panel and the graphic LC-display (back-lit 256x64 pixel) shows the system status and the gas concentration being detected. A serial port RS232 is also provided for the connection to a personal computer thus allowing a saving time The same port allows connection to remote programming and control systems (Personal Computer) that during the normal operation, provides the facility of copying, storing and viewing the programming data and event log from an on-line MTS control unit. The information transmitted to the computer are in SIA format that provides highly detailed information on each alarm or events, but the MTS control units can be customized with other kind of formats. The control units are housed in Metal cabinet or in a 19” 3 units rack with separate power supply which has to be ordered separately.
