The security system is not only as simple as installing a few cameras. To clearly express the design of the security system, you must be proficient in security terminology, understand it yourself, and express it clearly. The customer can understand it clearly. This is complete. A ring. Today, I will talk about 17 professional terms used in security systems.
1, risk level
The extent to which the protective object itself and its surroundings pose a security threat.
2, the level of protection
The level of precautions taken to protect the safety of the object.
3. Safety protection level
A program whose risk level is covered by the protection level.
4, detection
A means of detecting a dominant risk event or/and a hidden risk event and issuing an alert.
5, delay
Measures to extend or/and delay the progress of a risk event.
6, the reaction
Quick action to stop the occurrence of a risk event.
7, false alarm
An alarm issued by accidentally touching a manual device, an automatic device responding to an undesigned alarm state, a malfunction or damage of a component, an operator error, or the like.
8, leak alarm
A risk event has occurred and the system has failed to respond or indicate an alarm.
9, manpower prevention (human defense)
An organized preventive action (including people, organization, management, etc.) of a suitably qualified person and/or group of people performing security precautions.
10, physical defense (physical defense)
Various physical protection means (including buildings, structures, barriers, appliances, equipment, systems, etc.) that can be used for security purposes and can delay the occurrence of risk events.
11, technical prevention (technical defense)
Utilize various electronic information devices to form systems and/or networks to improve the security of detection, delay, responsiveness and protection functions.
12. Protection objects (units, parts, targets)
The object that needs to be protected because of the risk, usually includes a certain unit, a certain building (structure) or building (structure) group, or a certain local area inside and outside and a specific actual target .
13, the perimeter
The boundary of an area where physical protection or/and electronic protection is required.
14. Monitoring area
The area between the perimeter perimeter of the physical perimeter protection system or/and the electronic perimeter protection system and the boundaries of the protection zone.
15. Protective area
The area or part of the protection target that is allowed to enter and exit.
16, restricted area
Do not allow protected areas or parts of unauthorized access (or peek).
17. Blind area
An area within the scope of warning that security measures are not covered.
These security professional terminology security personnel must be familiar with and master.
Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.
