PICnet represents a complete solution for room call and automation systems in hospital structures.
Room call system
The PICnet system allows the creation and management of supervision calls for patients and / or medical and paramedical staff to reception rooms, to other rooms or departments, and to areas outside the hospital in order to guarantee high services and organizational standards that satisfy every type of request. In this context, the PICnet system, in addition to significantly improving the organizational conditions in hospitals, private clinics and nursing homes, increases the level of service and safety for patients and optimizes the efficiency and effectiveness of the health personnel who work there. All the information (for example, type of call, room number, bed number, event memory) and anomalies are detected, checked and displayed by the system, simplifying not only the work of those who use it, but also of the technical staff who installs it and will have to carry out any maintenance (for example in the event of an expansion of the system). The system will consist of a Master module management unit, located at the nursing staff's point of control, which will have the task of managing the calls and alarms that will come from the various rooms through the BUS cable and the modules distributed in the field.
Similarly to what is provided for patient rooms, alarm management in independent assisted bathrooms is carried out with a module for managing the following users:
The handy bathroom call signals and the alarm reset button are input, the relay output activates the light signal outside the door and the reassurance light.
At the request for assistance, the out-of-door signaling is activated and a special message is sent to the floor displays and at the control point.
The personnel in charge signals the acknowledgment of the alarm with the push of a button by turning on the reassurance light located in the bathroom.
For all the mixed PN 2I2O and PN 4I4O modules used in the rooms, a local operating mode is provided which, even in the event of a failure of the central unit of the bus system, allows the warning light to come on outside the door in the event of an alarm, always ensuring minimal system functionality
In the event of a patient alarm call, the corresponding light signal will be activated outside the door and an alarm message will be displayed in the monitoring station and on the floor display. The staff in charge will notify the patient of the receipt of the alarm by turning on the reassurance light and will go to the room concerned for the intervention. Once arrived, the alarm can be reset using the appropriate input contact and in the event of prolonged stay in the room, it can activate the call transfer which, in the event of an alarm coming from another room, will activate the acoustic signal. The call transfer will be activated by pressing a specific button or by prolonged pressing of the reset button and it will cause the door light to flash (to signal the presence of staff in the room) and the reassurance light as a reminder for the nurse. A further prolonged pressure on the call transfer command will end this function (with possible reset also from the control point). The operating logics are freely definable to implement further commands such as the assistance call from the bedroom and bathroom made by the nursing staff who requires assistance or the emergency call with the highest priority.
On each floor there is the presence of a display module which only displays the alarms relating to the floor, while the Master module located in the control point displays all the active alarms. In the event of an alarm, the buzzer on board these modules is activated and the relay output on board is activated to activate any further optical / acoustic signals. For each alarm, the date and time of activation and deactivation are stored in static memory so that the event can be checked in a delayed time.
In the event of several pending alarms, they can be displayed cyclically at a predetermined rate or on command. In addition, a push-button module or a mixed input / output module will be installed at the supervision point for the integration of control buttons and light indicators.

Transmission of room alarms
With the use of suitably prepared telephone centers, it is possible to propagate the alarm calls received by the system also on the pagers with which the structure's operators are equipped or on cellular telephones. By means of a converter module with RS232 serial port, the PICnet system can in fact send alarm messages to the telephone switchboard which then sends them as required.
Through PICnet systems it is possible to have remote signaling of any type of alarm or failure. All reports can be made locally, by means of alarm messages on the local supervision PC or on the display of the Master module, and remotely, by means of alarm messages on the centralized supervision PC or via messages and notifications remotely on any device.
It is also possible to interface PICnet building automation systems with security systems for sharing peripheral sensors, such as sharing window opening or presence sensors, and implementing operating synergies, such as “if a smoke sensor detects a fire principle, sends an alarm notification to the system, the room and hallway lights are turned on and the room door is unlocked”.
Thanks to the PICnet system, it is possible to automatically adjust the portion of artificial light as a function of natural light in order to guarantee the optimal lighting value in the environment and on the work surface in all circumstances. Depending on the distance from the windows, each sensor reads a different brightness value.
At this point, the system will calculate the difference needed to reach the set brightness and therefore increase or decrease the intensity of the artificial light component. In the same way, it will be possible to open and close the curtains automatically, so as to receive sunlight only when it does not disturb the sight of the workplaces in compliance with the current legislation. The system also allows the possibility of creating scenarios, with automatic and synchronized start-ups according to user-definable logics.
Thanks to the PICnet system, it is possible to manage access to the various departments in complete safety using transponder badge readers, which ensure a very high level of reliability in terms of security, with the recording of every transit both for the service personnel and the employees. Each code corresponds to a different user, who has free access to the departments of his competence only on the established days and times.
The technology used places this product at the forefront of its sector since the identification card for access is made up of a normal credit card format card without magnetic stripe or electrical contacts. In this way, the typical malfunctions of traditional technologies due to damage to the magnetic strip or oxidation of the contacts are totally eliminated. Each badge reader can store up to 1300 different card codes in a range of 65000 different codes. The different card codes can be divided into 8 distinct groups, enabling the activation or deactivation of all the cards belonging to the same group according to certain parameters, such as an hourly consent.
The PICnet system allows to identify the most suitable solution for optimal management whatever the temperature control system adopted. The system manages any source of heating and air conditioning (heat pump, electric, radiant floor, monosplit, multisplit systems etc.) in an extremely simple way. In the case of radiators, floor systems or fan-coils, the PICnet modules have relay outputs to control the zone valve or the convector speeds and are available for the main civil series. In the case of radiant cooling systems, the use of the temperature and humidity probe prevents the formation of condensation on the floor. Thanks to the programming power and the flexibility of the system, it is possible to implement various functions aimed at saving energy, such as the limitation of the temperature regulation range by the occupants that can be set from the PC or the automatic setting of a maintenance temperature in particular time windows.
It is possible to automatically set a minimum 'antifreeze' temperature in periods of non-use, deactivate the temperature control when opening the windows and switch centrally summer / winter settings. In the case of direct expansion (split) air conditioning systems that do not have controls or signals suitable for centralized management in the terminal block, the system will be managed by modules that have an infrared transmitter with high emission power. Thanks to a patented technology, the PICnet modules are able to fully reproduce the commands from the remote control, not just replicating predefined set points, thus guaranteeing full remote control of the unit, through centralized supervision. Throughout its history Sinthesi has developed PICnet integrations with the most popular brands and models of air conditioning systems, such as Daikin, Fujitsu, LG, Mitsubishi, GREE, Panasonic, Sharp, Toshiba and many others.
Thanks to PICnet it is possible to optimize energy consumption and improve the energy class of the entire building. In many cases PICnet systems are a fundamental component for obtaining the LEED (Leadership in Energy and Environmental Design) international certifications, established by the U.S. Green Building Council.
In fact, it is extremely simple to adjust the temperature and lighting of the rooms according to optimal automatic profiles and reduce inefficiencies due to system malfunctions thanks to constant monitoring of technological systems and timely reports in the event of failures.
Through the use of appropriate PICnet modules, it is possible to centrally manage all the technological users of the system (thermal power station, pumping stations, air conditioning units, etc.). Similarly, all the related technological alarms, such as tripping of switches, thermal relay tripping, technological alarms, alarm call for disabled bathrooms and opening of security doors can be signaled at the point of supervision.
All signals can be sent via alarm messages on the supervision PC or on the Master module display. In the event of technological alarms, SMS messages and notifications can be sent automatically to the electrical or hydraulic maintenance technician of the system.
