1) Which parts of the alarm system consist of?
Answer: A simple alarm system consists of a front-end detector, an intermediate transmission part and an alarm host. Larger systems can also regard the detector and the alarm host as the front-end part, the transmission part from the alarm host to the alarm machine, and the central alarm-receiving part as the back-end part.
2) According to different information transmission methods, which types of alarm systems can be divided into?
Answer: According to the different ways of information transmission, the distance from the detector to the host can be divided into three types: partition, bus and wireless. From the host to the central alarm machine can be divided into two types: wired and wireless.
3) What is an alarm host?
Answer: Alarm host: The "brain" part of the alarm system, which processes the signal from the detector and controls the alarm system by providing arming and disarming operations through keyboards and other devices. It can provide sound/light prompts when alarming, and at the same time, the alarm information can be transmitted to the alarm center through the telephone line.
4) What are the common types of defense zones in the alarm system?
Answer: Common types include entry and exit zones, real-time zones, internal zones, and 24-hour zones.
5) What is the entry and exit zone?
Answer: Entry and exit zones are also called delayed zones. After arming, the system will provide a certain time delay time for entering and exiting the defense zone. After the exit delay time expires, the delay defense zone system alarm will be triggered. When the delay zone is triggered when entering, the controller will beep during the entry delay time as a reminder signal to disarm the system. The system must be disarmed within the set delay time, otherwise it will alarm. This type of defense zone is suitable for the user's entry/exit operation keyboard must pass.
6) What is a real-time defense zone?
Answer: When the real-time defense zone is triggered after the system is armed, it will alarm immediately and there is no delay time.
7) What is an internal zone?
Answer: Internal defense zone: After the system is armed, if the entry and exit zone is triggered first and then the internal defense zone is triggered, the internal defense zone will also enter the delay state and will not immediately alarm. The delay time of the defense zone is the same as the entry and exit zone. If the internal defense zone is triggered before the entry and exit zone is not triggered, the system will immediately alarm. This type of defense zone is suitable for the user to operate the keyboard after the completion of the place, such as the detector installed in the hallway, lounge or hall. It is suitable for preventing intrusions that hide in the hall before the system is deployed or try to reach the hall without passing through the entry and exit zone.
8) What is the surrounding defense zone?
Answer: Peripheral defense zones are used for exterior doors and windows. When the defense zone is triggered, an alarm will be issued immediately.
9) What is a 24-hour defense zone?
Answer: The 24-hour defense zone is not affected by arming and disarming, and the zone is triggered and alarms immediately.
10) What is a 24-hour audible emergency zone?
Answer: 24-hour audible emergency defense zone: It is a kind of 24-hour defense zone. When this type of defense zone is triggered, the external warning lights and siren will give out sound and light prompts, and display an alarm on the keyboard. This type is suitable for emergency buttons.
11) What is a 24-hour silent emergency zone?
Answer: 24-hour audible emergency defense zone: It is a kind of 24-hour defense zone. When this type of defense zone is triggered, the external warning lights and siren will not emit sound and light prompts, nor display alarms on the keyboard. This type is suitable for emergency buttons in important places such as banks and jewelry counters.
12) What is a fire zone?
Answer: Fire zone: It is a kind of 24-hour zone. A fire alarm signal will be issued when the defense zone is triggered, and the keyboard will display the defense zone number and trigger an external siren to sound a special alarm. For use in a 24-hour fortified area equipped with smoke detectors, heat detectors or emergency buttons.
13) What is out-of-office arming?
Answer: Out-of-office arming: refers to a mode of arming the system when all users leave the protected area of the alarm system. In this mode, all defense zones in the system are in working state.
14) What is left-behind arming?
Answer: Stay-behind arming: refers to a mode of arming the system when the user is in the internal protection area of the alarm system. In this arming mode, all surrounding defense areas in the system (such as outdoor perimeter probes, window magnets, and balcony curtains) Type probe, etc.) is in the armed state, and the internal defense zone in the system (usually an infrared probe installed indoors) will be automatically bypassed by the system, and internal personnel can automatically move in this area without generating an alarm.
15) What is disarming?
Answer: Disarming: refers to the alarm panel exiting the alert state by password or key method.
16) What is to eliminate the alarm?
Answer: The system has alarmed during the arming period, and there is still a prompt on the keyboard after the defense is disarmed. To eliminate the alarm is to stop the alarm sound and return to the disarmed state by operating again after disarming.
17) What is the entry delay?
Answer: Entry delay: It means that after a person enters and exits the defense zone outside, the entry and exit defense zone is triggered, but at this time the system will not immediately alarm, but is in the entry delay state (usually tens of seconds). During this process, you must immediately disarm the alarm system correctly, otherwise the system will generate an alarm after the entry delay expires.
18) What is the outgoing delay?
Answer: Outgoing delay: refers to the delay time (usually several tens of seconds) left for the operator to leave the zone after the system is armed. You must leave the entry and exit zone within this period of time, otherwise you will trigger the entry and exit zone after the delay expires.
19) What is bypass?
Answer: Bypass: When arming, one or some of the zones will not be added to arming.
20) What is the administrator password?
Answer: The password used by the management personnel, through which you can enter the programming of the system and set various items of the system.
