1) What parts does the alarm system consist of?
A: A simple alarm system consists of a front-end detector, an intermediate transmission part and an alarm host. A larger system can also regard the detector and alarm host as the front-end part, the transmission part from the alarm host to the alarm receiver, and the central alarm receiver as the back-end part.
2) According to different information transmission modes, what kinds of alarm systems can be divided into?
A: According to the different information transmission modes, there are wired and wireless from the detector to the host. From the host computer to the central alarm receiver, it can also be divided into wired and wireless, and the wired system can also be divided into two types: transmission based on telephone line and transmission based on bus.
3) What is the alarm host?
Answer: Alarm host: the "brain" part of the alarm system, which processes the signals of detectors, provides arming and disarming operations through keyboards and other devices, and controls the alarm system. When giving an alarm, it can provide an audio/optical prompt, and at the same time, it can transmit the alarm information to the alarm center through the telephone line.
4) What are the common area types in alarm system?
A: There are several common types, such as entry-exit defense zone, immediate defense zone, internal defense zone and 24-hour defense zone.
5) What is the entry and exit area?
A: Entering the defensive zone is also called the delayed defensive zone. After the protection is deployed, the system will provide a certain delay time for entering and leaving the defense zone, and when the delay time is over, it will trigger the alarm of the delayed defense zone system. When entering, the delay zone will be triggered, and the controller will give a buzzer within the delay time as a prompt signal to cancel the system. The system must be disarmed within the set delay time, otherwise an alarm will be issued. This type of forbidden area is suitable for the user's input/output operation keyboard.
6) What is the instant zone?
A: When the real-time defense zone is triggered after the system is deployed, the alarm will be given immediately without delay.
7) What is the internal defense zone?
A: After the system is deployed, if the access area is triggered first, and then the internal area is triggered, the internal area will also enter a delayed state, and no alarm will be given immediately. The delay time of this area is the same as that of the access area. If the internal defense zone is triggered before the access zone is triggered, the system will call the police immediately.
8) What is the perimeter defense zone?
A: The perimeter defense zone is used for external doors and/or windows. When the defense zone is triggered, an alarm will be issued immediately.
9) What is a 24-hour restricted area?
A: The 24-hour defense zone is not affected by the deployment and withdrawal of defense, and the defense zone is triggered to call the police immediately.
10) What is a 24-hour emergency zone with sound?
Answer: 24-hour emergency zone with sound: it is a kind of 24-hour zone. When this type of area is triggered, the external alarm lights and alarm signals will give sound and visual prompts, and the alarm will be displayed on the keyboard. This type is suitable for panic button.
What is a 24-hour silent emergency zone?
Answer: 24-hour emergency zone with sound: it is a kind of 24-hour zone. This type of area is triggered, and the external alarm lights and alarm signals will not give audible and visual prompts, and the alarm will not be displayed on the keyboard. This type is suitable for banks, jewelry counters and other important places in panic button.
12) What is a fire zone?
Answer: Fire zone: It is a 24-hour protected zone. When the area is triggered, a fire alarm signal will be sent out, the area number will be displayed on the keyboard, and an external alarm signal will be triggered to give a special alarm sound. Used in areas with smoke detectors, thermal detectors or 24-hour safety panic button.
13) What is out-of-town security?
Answer: Going out protection refers to a mode to protect the alarm system when all users leave the protected area. In this mode, all sectors in the system are working.
14) What is left-behind protection?
Answer: Left-behind protection refers to a way to protect the alarm system when the user is in the internal protection area. In this protection mode, all peripheral protection areas in the system (such as outdoor perimeter probes, window magnets, curtain probes on balconies, etc.). ) are in the protection state, and the internal protection area in the system (usually the infrared probe installed indoors) will be automatically bypassed by the system, and the internal personnel can automatically move in this area without giving an alarm.
15) What is disarmament?
Answer: disarming: it means that the alarm host is out of the alert state by means of password or key.
16) What is alarm cancellation?
Answer: The system gives an alarm during the protection, and there are still prompts on the keyboard after the protection. Disarming the alarm means stopping the alarm sound by operation again after disarming, and returning to the disarming state.
17) What is the entry delay?
Answer: Entry delay: it means that the entry and exit of the safe area will be triggered immediately after the personnel enter the safe area outside, but at this time, the system will not give an alarm immediately, but will be in a state of entry delay (generally tens of seconds). In this process, you must immediately and correctly disarm the alarm system, otherwise the system will generate an alarm after the delay is over.
18) What is an out-of-office delay?
Answer: Going out delay: refers to a delay time (generally tens of seconds) left for the operators to leave the defense zone after the system is armed. You must leave the access area within this time, or you will trigger the access area after the delay is over.
