1 Overview

For the house alarm, burglary, fire, gas leakage, etc. are all possible at any time, but the previous anti-theft nets and anti-theft door protection methods not only hinder the aesthetics, unfavorable requirements for fire prevention but also cannot effectively prevent the intrusion of damage. It is particularly important to establish a safety alarm system to protect the safety of the family. The burglar alarm system and monitoring system can not only effectively prevent the intrusion of sabotage and detect the leakage of gas, but also can clearly understand the situation of the family from a long distance and comprehensively protect the family security.

2 House Alarm Requirements

• In the event of a gas leak, fire, or someone trying to enter from any part of the house, the house alarm system will immediately call the police and call the owner
• The owner can clearly monitor everything outside in the house
• Real-time linkage of alarm monitoring and recording can be saved
• Security personnel can monitor the situation of the house in the alarm monitoring center through the Internet

3 House burglar alarm technology measures

Currently, the burglar alarm measures mostly rely on civil defense and object defense (such as anti-theft doors, iron guardrails, etc.). If conditions permit, adopting technical prevention measures will achieve more effect.

(1) Install an alarm control panel and PIR motion sensors. When the PIR motion sensors work normally, they can emit invisible infrared light. As soon as a person enters the detection range, the sensors will immediately send a signal to the alarm control panel, the alarm control panel will alarm. If a thief enters, residents can immediately detect the thief and take action to deal with it.

(2) Install electromagnetic password door lock. To install this type of lock, you need to first press the password when unlocking from outside, otherwise it cannot be unlocked. If the password lock is pried open, the alarm device on the password lock will emit an alarm sound. This will startle people or neighbors indoors, which can scare away thieves and also capture them.

(3) Participate in the community network alarm system. After installing this alarm device, if a user encounters a dangerous situation (such as burglary), the alarm will automatically sound an alarm through a pre-set defense zone. The alarm receiving device of the alarm  monitoring center will immediately display the user’s exact address, and the security personnel can quickly arrive at the scene of the crime to deal with it.

4 Basic applications of house burglar alarm system

The house burglar alarm system is an important facility for preventing accidents such as theft, robbery, and fire. Once an unexpected event occurs, the owner can be quickly notified via phone or internet, facilitating quick emergency measures to prevent accidents or disasters from spreading.

The house burglar alarm system utilizes an alarm control panel to connect various detectors wirelessly or wired to achieve burglar alarm functions. Connect the alarm control panel to a landline telephone line or upload it to the alarm monitoring center. If there is an alarm, dial the alarm number or send the alarm message according to the customer’s set phone number.

The house burglar alarm system usually consists of three parts: alarm detector, transmission channel, and alarm control panel. An alarm detector is a device composed of sensors and signal processing, used to detect intruder intrusion behavior or smoke, etc. It is a key component of the burglar alarm system, and the sensor is the core component of the alarm detector. By using sensor components with different principles, different types, purposes, and detection purposes of alarm detection devices can be formed.

Common detectors include PIR motion sensor, door contact, smoke detector, gas detector, flood detectors, etc.

Active infrared detectors have strong anti-interference performance and are installed outdoors, making them irrelevant to indoor personnel activities. As long as active infrared detectors are installed at the perimeter entrances and exits of your house, once someone enters the room, they will report to the alarm control panel in a timely manner, ensuring life safety and property integrity. This serves the purpose of early prevention and minimal consequences.

5 House Alarm System Design

This network house alarm system solution combines the burglar alarm system with the monitoring system (CCTV).

The burglar alarm system is divided into 3 protection areas, namely the perimeter protection area, the residential protection area, and the kitchen protection area. Each protection area is equipped with a sound and light alarm. In the state of fortification, as long as there is an intrusion or gas leakage, the burglar alarm system will automatically issue a flashing siren on the scene to warn. At the same time, the burglar alarm system will automatically notify the house owner and the alarm monitoring center.

The monitoring system records all the conditions as on-site evidence.

The personnel of the alarm monitoring center can view the live video of the alarm location in the alarm monitoring center in real-time, and deal with it immediately.

6 Solution Composition

This network house alarm system solution consists of two parts, the burglar alarm system, and the monitoring system.

6.1 Burglar alarm system part

The burglar alarm system generally consists of 4 parts, namely the detector, signal transmission system, alarm control panel, and alarm monitoring center. Its working principle is that in the state of fortification, various detectors detect gas leakage, intrusion, etc. After that, the detector transmits the detected signal to the alarm control panel through the signal transmission system, and the alarm control panel links the sound and light alarm to make an on-site alarm and notify the house owner and the alarm monitoring center for immediate processing.

The detector is the nose of the burglar alarm system. It is at the bottom level and is responsible for detecting illegal intrusion. If there is an abnormal situation, it sends information to the burglar alarm control panel and sends an alarm through the sound and light alarm. The detector is the first and most important step in the burglar alarm system. Therefore, choosing a detector with good detection performance and stable operation is related to the success or failure of the burglar alarm system. According to the requirements of house alarm, the detectors used in this scheme include electric security fences, beam sensors, PIR sensors, glass break detectors, door contacts, gas detectors, smoke detectors, etc.

6.2 Functional characteristics of house alarm system

6.2.1 Burglary: The burglar alarm system is divided into 3 protection areas, namely the perimeter protection area, the residential protection area, and the kitchen protection area. They are combined with the fence, inside and outside, and physical defense and technical defense are combined to fully protect the safety of the family. There are no blind spots. As long as there is an act of sabotage, the detector will detect and alarm to deter the act of sabotage.

6.2.2 Fire prevention: A gas detector and a smoke detector are installed in the kitchen, and a gas detector is installed in the bathroom to protect the places most likely to cause a fire. As long as the gas leaks to a certain degree and the smoke reaches a certain concentration, the detector will detect and alarm and tell the owner to pay attention to safety.

6.2.3 Remote alarm: The alarm control panel can set 4 groups of alarm phone numbers. When a person is not at home, the detector detects and alarms, and the burglar alarm control panel remotely dials to tell the owner of the preset number that something happened at home. In order to prevent the invasion, the owner can take measures to hinder the destruction of the invasion.

6.2.4 Remote monitoring: The alarm control panel adopts advanced technology and has a networking function. The alarm monitoring center can know the alarm situation of the house through the alarm receiver or the AS-ALARM network alarm center management system.

6.2.5 Stable work: It uses independent wiring for power supply, and the system works stably. In the event of a power failure, the system automatically switches the standby power supply, which has no effect on the operation of the system.

6.3 Monitoring system part

At present, monitoring systems are increasingly being widely used in households. The use of a house alarm system in conjunction with a home monitoring system will make the home security system more comprehensive.

7 Product Selection

7.1 Burglar alarm system equipment

The house alarm system uses fully automatic burglar electronic equipment to judge illegal intrusion or various gas leaks through electronic infrared detection technology and various magnetic control switches in places where no one is on duty; through the speaker of the alarm control panel or flashing lights to realize on-site alarm. At the same time, the alarm information is transmitted to the alarm monitoring center or the owner himself through the public telephone network or other transmission methods. At the same time, when someone has an emergency at home, they can also send emergency distress information to the alarm monitoring center of the residential community through various wired, wireless emergency buttons or keypads. The house alarm system consists of the following parts：

(1) Alarm control panel

The most important equipment in the control part of the burglar alarm system is the alarm control panel, which is the brain of the entire system, and its function is to analyze, judge, and process the signal from the detector. After receiving the alarm signal, the alarm control panel will alarm according to the preset alarm method. When an intrusion alarm occurs, it will connect the sound and light alarm model to deter criminals, avoid further intrusion damage, display the intrusion position, and facilitate personnel to deal with the alarm. If the alarm control panel is connected to the residential community alarm monitoring center, the alarm signal can be transmitted to the residential community alarm monitoring center. The equipment used in the control part of the burglar alarm system includes the Athenalarm alarm control panel and remote control. 

(2) Remote control

Used for arming and disarming alarm control panels, using the same method as common car burglar remote controls.

(3) PIR motion sensor

It adopts microcomputer digital signal technology, is a high stability detection device with innovative design. It has temperature compensation, strong white light resistance, electromagnetic interference resistance, and eliminates various false positives. When the intruder passes through the PIR motion sensor, it sends a signal to the alarm control panel which then alarms.

(4) Door contact

After the alarm control panel is armed, the intruder opens the doors and windows equipped with a door contact. The door contact sends a signal to the alarm control panel, and the alarm control panel immediately starts the alarm.

(5) Smoke detector

It uses an advanced radioactive source and contrast space, and open space to radiote heavy ions. Whether it is open fire, no fire, smoke, no smoke burning, it is more sensitive. When the smoke detector detects harmful gas, the red indicator light is bright and the alarm signal is sent to the alarm control panel.

(6) Gas detector

• Detection range: detection of combustible gases, such as methane, ethane, liquefied petroleum gas, etc.
• Detection concentration: methane, propane, ethane greater than 10000PPM; alcohol, acetate greater than 1000PPM; ethylene, ammonia greater than 500PPM
• Working environment temperature: -10 ℃~5 ℃
• Humidity: less than 95%

(7) Panic button

When the user encounters an emergency situation and triggers the panic button, the panic button sends a signal to the alarm control panel, and the alarm control panel immediately starts the alarm.

7.2 Monitoring system

7.3 Alarm monitoring center

The alarm monitoring center uses the burglar alarm system in conjunction with the monitoring system to facilitate the handling of the alarm.

The alarm monitoring center uses AS-ALARM network alarm center management software to combine the burglar alarm system of each house with the monitoring system. When an alarm occurs in the house alarm system, the alarm information, electronic map, real-time video, etc. can be displayed in the alarm monitoring center, and the personnel of the alarm monitoring center can immediately deal with the situation according to the scene. (Recommend)

The alarm monitoring center can also use the alarm receiver to connect the house alarm control panel. When the house alarm control panel alarms, it will send the alarm to the alarm receiver of the alarm monitoring center. The alarm monitoring center staff should understand the situation and deal with it. (Not recommended)

8 The main functions of various devices in the house alarm system

(1) Alarm control panel part

The alarm control panel part is composed of an alarm control panel, keypad, remote control, and UPS uninterruptible power supply. Mainly completing alarm settings, receiving detector signals to trigger alarms, remote control defense, arming and disarming. The alarm control panel is installed in a concealed and secure location to prevent malicious damage.

(2) Kitchen gas leakage and smoke detection part

Install gas detectors and smoke detectors in the kitchen. When there is a gas leak in the kitchen or the kitchen accidentally emits smoke and catches fire, the detector immediately sends an alarm signal to the alarm control panel.

(3) Door and window detection part

Install a door contact on each door and window. When the alarm control panel is armed, the doors and windows are opened, and the door contact sends an alarm signal to the alarm control panel.

(4) PIR motion sensor

The PIR motion sensor is installed in the inner corner of the window, forming a fan-shaped detection area in front of the entire window. When an intruder passes through the PIR motion sensor, the PIR motion sensor sends an alarm signal to the alarm control panel.

(5) Panic button

When the owner encounters an emergency situation or needs emergency assistance, press the panic button, which sends a signal to the alarm control panel, and the alarm control panel will alarm in a predetermined manner.

9 House burglar alarm system layout

9.1 Determine the scope of precautions needed based on the room situation

In a family, balconies and doors are located in the most vulnerable locations to intrusion. Next is the windows of the kitchen and study (as the study and kitchen are usually unoccupied, especially at night, they are often empty and can easily become entrances for thieves). Once again, there is the master bedroom, children’s room, and bathroom.

9.2 Determine defense zones and the prevention methods and equipment for each zone

After identifying the locations and areas that are susceptible to intrusion, the number of defense zones should be determined based on factors such as your surrounding environment, community security measures, house environment, and your economic situation (of course, it is best to set up defenses for all vulnerable areas). Here, we will temporarily take the example of setting up defenses for all the above areas and configure various burglar alarm devices. You can add or remove relevant devices according to your specific situation:

(1) Economical configuration:

2 PIR motion sensors, 2 door contacts, and 1 alarm control panel.

Economical configuration can achieve the following functions:

In the event that the doors and windows of the main entrance, study, or kitchen are opened or pried open, causing the door or window to shift more than 1 centimeter, or when a person enters the bedroom and living room from the balcony in a guarded state, the corresponding detector will drive an alarm. After receiving the alarm signal, the alarm control panel turns on the high pitched siren and dials the pre-set phone number of the owner’s phone, neighbor’s phone, etc. to give an alarm.

(2) Basic configuration:

On the basis of the above economical configuration, we have installed one PIR motion sensor in each of the children’s room, living room, and study, and one door contact in the window of the bathroom. In this way, we have completed a basic house burglar alarm system, and installed dual detection equipment in key defense areas (door, study). The equipment is as follows:

4 PIR motion sensors, 3 door contacts, and 1 alarm control panel.

The basic configuration can achieve the following functions:

When the doors and windows of the main entrance, study, kitchen, and bathroom are opened or pried open, causing the door or window to shift more than 1 cm, or when a human body enters from the balcony, children’s room, or study in a guarded state. At the same time, due to the double defense measures taken at the entrance and study, the preventive effect can be effectively guaranteed.

(3) Functional configuration:

To solve the problem of basic configuration not being able to provide better protection for balconies and windows, we have installed beam sensors on balconies and windows, and removed some indoor PIR motion sensors. The equipment is as follows:

3 beam sensors, 1 PIR motion sensor, and 1 door contact, and 1 alarm control panel.

Functional configuration can achieve the following functions:

In the configuration, we use beam sensors outside the balcony and windows for defense, which can promptly alarm when someone approaches the balcony and windows. It can prevent intruders from entering the room and causing direct conflict with the owner, better ensuring personal and property safety.

9.3 Optional devices and optional other devices to enhance prevention functions

On the basis of the above configuration, we can also choose:

• Replace the ordinary PIR motion sensor with an intelligent detector or microwave detector
• Install gas detectors in the kitchen
• Install linked light device in the living room (when someone approaches the window, the alarm will sound and the living room lights will automatically turn on)
• Install digital anti-theft locks at the entrance
• Install glass detectors on glass

It should be noted that burglar alarm products should not only focus on new technologies, but also pay more attention to stable and mature conventional reliable products. In situations where the public security environment is relatively good or economic conditions are constrained, we only set up defenses for the entrance, balcony, kitchen, and study. Among them, wireless door contacts are used for the entrance, kitchen, and study, while PIR motion sensors are used for security in the living room and bedroom.

10 Installation

• Install Athenalarm alarm control panel and monitoring equipment in the house
• Install perimeter protective equipment such as electric security fences, beam sensors around the house
• Install PIR sensors, glass break detectors, door contacts, and other detection equipment at important entrances and exits of houses, windows, garages, etc.
• Install smoke detectors, gas detectors, and other detection equipment in the living room, room, kitchen, etc. of the house
• Install cameras on each outdoor surface to monitor and record the surrounding area for 24 hours
• The alarm monitoring center installs the alarm receiver, AS-ALARM network alarm center management software

It is recommended to use an alarm control panel for each house. The owner of the house can personalize the alarm system of the house. When there is a sabotage intrusion, the sound and light alarm will send out sound and light alarms to hinder the personnel who sabotage the intrusion. The alarm monitoring center has an intuitive understanding of where is the alarm situation, easy to deal with.
