The new building requires the access control system to control elevators by granting access on certain floors for users based on their predefined access level. The public address system, in addition to background music, shall announce override messages in cases of emergency and fire alarm. The IP CCTV shall be accessible from the same interface that monitors the BMS and the access logs. The BMS system shall control and monitor typical HVAC equipment such as AHUs and FCU, but it shall also control operation rooms and isolation rooms which had their own third-party specially designed control system.
The operation and isolation rooms were equipped with a specially designed control system supplied by “Maquet” called “Tegris”. The BMS was integrated with this system, by sending and receiving signals from it, resulting in a complete control and monitor over the operation and isolation rooms. Typical HVAC equipments were also controlled including AHUs and FCUs. FCU were supplied by Airmec and was seamlessly integrated via the Modbus standard protocol. In addition to the HVAC, monitoring the MDBs and SMDBs was accounted for and alarms were raised in case faults occur.
Around 200 high specs cameras were installed in various locations and configured to provide real-time monitoring as well as sub-streams for recording on a large storage NVR. 5MP cameras were deployed to ICU rooms so that the doctors can monitor the patients from tablets showing the slightest sign of any discomfort the patients may suffer. The NVR hosted advanced VMS software to provide additional features and digital signal processing for camera feeds such as face recognition and record on motion to save space.
The access control system controls over 200 doors equipped with card readers, magnetic locks, exit buttons and door contact for feedback. Permissions and access levels are defined and configured using the same server that already controls BMS and CCTV along with card programming device to remove or add cards from the database and give each card its desired access level. The access control system also allowed for the integration of elevators in terms of allowing users to stop on certain floors based on their access levels. The integration required special programming on the main server to provide fast and reliable RS232 communication with the elevators system.
Finally, over around 400 speakers were distributed across the floors and in different places to ensure full coverage of audio for all areas. Special zoning design was applied for example, dedicating a zone for stairs, others for each floor depending on what department it is. This provides the ability to page each zone independently as desired. Most importantly, allowing critical fire alarm messages to be broadcasted overriding any current audio playing.
The main server holds the core engine to monitor and control the BMS, CCTV and Access Control System, hence integrating these systems together and giving easy and quick access for the client over the whole system from a single interface. The system can also be accessed remotely in cases it was needed. This is what can be called a truly Integrated Building Management System.
