Two, detailed design of the alarm system
In order to meet the high-tech hospital technical experts and the requirements of the bidding documents, a better understanding of the solutions provided by the company, to understand the system equipment selection, equipment connection and inter-system communication. Connection and communication between the system, is described below:
1. System product selection
According to the requirements of the tender documents of the High-tech Hospital, the selection of equipment in the selection of the user's needs are fully taken into account, the company will mainly use Honeywell's alarm equipment.
2. Alarm system working principle
Specific block diagram is as follows:
Anti-Zone Alarm Host
Antenna Detector
Audio-visual alarm
Related Departments
Telephone Lines Phone Lines
From the diagram, we can clearly see the composition of the equipment of the automatic alarm system and the alarm signal flow and alarm process.
Each front-end host can be connected to different types of detectors, and the settings of each type of detector will be different according to the user's preventive functions. For the prevention of the perimeter area of the system, the use of infrared convection detectors.
When the front-end host is in working condition, the host can detect the changes in the front-end circuit in a very short time, such as circuit breakage, short-circuit or load value change, the host will send out sound and light alarms or produce silent alarms according to the function setting, and at the same time, the host will automatically dial the number and transmit the relevant alarm information to the alarm center through the telephone line.
The center alarm host receives the alarm signal can be issued by the audible alarm prompts the duty officer, and shows specifically which preventive parts of the alarm, and can be dialed through the dialer to dial the phone number of the relevant personnel.
3. System specific design
1) Alarm system design
Mainly for the hospital's perimeter wall around the precautionary, 14 pairs of 150 meters and 30 meters of infrared convection detectors, each pair of detectors as an independent defense zone, in the arming time of any intruder through the wall or thrown by the wall outside the equipment blocking the detector's infrared will trigger an alarm ( mainly at night). Mainly at night). The central control room will receive alarm information at the same time, the main part of the camera can be installed, when the alarm can be viewed through the nearby cameras to confirm the alarm, set the relevant phone number through the voice dialer, can automatically dial the relevant phone.
2) Alarm center design
Monitoring and alarm center to set up an alarm host, keypad, battery backup 1 set, to ensure that the system can work properly in the event of a power failure, to further ensure the reliability of the system.
Prevailing alarm zone arming and disarming unified in the control center.
