Q1: What are the main functions of intrusion detection and alarm controller?
A: 1. Supply power to front-end alarm detectors
2. Receive the alarm signal from the alarm detector
3. Analyze and judge the received electrical alarm signals for further processing
4. Start the alarm device such as alarm lamp, alarm siren, etc. to send the alarm.
5. It can indicate the location of the alarm.
6. Can report an alert to an emergency centre or other relevant department via telephone lines or other means of communication.
7. Drive peripherals, such as turning on camera, VCR, lighting, starting printer printing.
8. The system can conduct self-inspection to check whether the work of each part is normal, or send a fault alarm signal.
9. The system can be programmed through the keyboard, which can better meet the needs of different users.
Q2: What is the working status of the intrusion alarm system?
A: 1. Arm status, that is, the normal state of alert
2. Disarm status. At this status, the system detector is not working.In the state of disarming, the detector will not send an alarm signal to the alarm controller even if there are abnormal situations on the scene.
3. Bypass status, it means that the operator sets bypass instruction for a certain defense area, the detector in the defense area will be bypassed from the whole detector group and cannot enter the working state.
4. 24-hour monitoring status, in which some zone detectors are set to work all day and are not affected by the disarming.
