 An Xonik SW-60 type acoustic annunciator is used as a multi-channel telephone line alert device.

 The system operates as follows. When the system is turned on using the microprocessor of the central control and control unit 1, the initialization program is executed, and at least one I / O block 3 is logically connected to the common bus 2. The initialization program by sequentially polling the signs of activity of the input-output blocks 2 determines the logically connected input-output block 2 and starts exchanging with it, displaying its initialization parameters on it. Next, the initialization program, using a software-implemented dialogue, asks for readiness to connect security sensors 4, fire sensors 5, water presence sensors 6, air temperature sensors 7, gas sensors 8, sensors for environmental pollution factors 9, water supply shutdown devices 10, devices 11 gas supply shutdowns, devices 12 for switching on / off lighting and power devices, devices 13 for controlling heating devices, devices 14 for controlling ventilation and air conditioning , A multi-channel device 15 alerts telephone line, an acoustic warning device 16 and the device 17. In the presence of a call sign of willingness to connect any of these devices, the program performs a logical procedure to connect the device. Thus, using the initialization program, the core of the system is configured for a specific number and functional purpose of the devices included in the system. The kernel of the system is configured by connecting devices to the system interfaces in series by loading the corresponding software drivers (for example, the central control and management device resident in the permanent memory block 22) and activating the devices. In this case, the activation of devices means the process of turning on and loading the corresponding microprocessors that are part of these devices. When the device is logically connected to the RAM 23 of the central control and management unit 1 in accordance with the initialization algorithm, an entry is made in the table of external devices. This entry fully describes the functional purpose of the device, its type and unique address in the system. After creating entries in the table, the system is completely ready to work with this device.

 When changing the number of security and fire sensors, water presence sensors, air temperature sensors, gas sensors, sensors of environmental pollution factors, water supply cut-off devices, gas cut-off devices, devices for switching on / off lighting and power supplies, control devices for heating devices, ventilation and air conditioning controls and other devices, the system can be reconfigured. When the reconfiguration algorithm is executed in the dialogue with the system, the required number of devices and their specification (the functional purpose of the device, its type and unique address in the system) are entered using the I / O block 3, after which the table of external devices and the corresponding software activation of these devices are updated .

 After configuring the system, a test is performed of the connected devices (security and fire sensors, water presence sensors, air temperature sensors, gas sensors, sensors of environmental pollution factors, water supply cut-off devices, gas cut-off devices, devices for switching on / off lighting and power supplies , control devices for heating devices, control devices for ventilation and air conditioning and others) by simulating possible emergency tuations and checking the correctness of system reactions. In addition, the operability of the devices themselves and the possibility of disconnecting them in manual mode from the I / O command unit are checked.

 System self-testing during operation is carried out using periodic software testing initiated by the central control unit 1 by timer. The testing device is addressed using the table of external devices. When a command to start testing is received through the interface of the device under test to the control inputs (for example, external interrupt inputs) of the device microprocessor, it is interrupted, followed by a test program located in the device’s permanent memory. After testing the test program, the processing results through the interface part of the device under test and the common bus 2 enter the RAM 23 of the central control and control unit 1, where they are compared with the standard and a working decision is made on the further operation of the device. Thus, the health of the system paths and, accordingly, their readiness are constantly monitored. In addition, in the system there is the possibility of an ad hoc test run, which is carried out using the input-output unit 3 in order to diagnose the device at any time. If any deviations from the norm are detected, appropriate warning messages are issued in all forms available in the configuration (text on the display 30 of the input-output unit 3, a tone, a voice message, including a telephone line).

 Input into the system of initial data is carried out using input / output blocks 3. When entering the initial data, the date and time are set, the reference points are set day-night, the host and user codes are entered (family members, employees, security, etc. based on the purpose of the room ) A number of parameters are introduced that are adaptable for the user — the waiting time for arrival and departure before the system enters the "Alarm" state and a number of others that have a service value. For example, if the configuration has the ability to control heating, lighting, audio support, the corresponding service setting is made. Next, the list of telephone numbers for messages on each channel is filled in - “Fire”, “Security”, “Water leak”, “Gas leak”, “Alarm”. Voice messages are recorded with verification for notification over telephone lines. If there is an audio accompaniment in the configuration of the device, messages are recorded for conducting the speech protocol — greeting, farewell, and a standard set of messages.

 Upon completion of the initialization and configuration programs, testing and input of initial data, the system is ready for operation.

The system operates in the following modes and sub-modes:
- host presence:
day (PC-D),
night (PH-N),
- lack of host:
day (O-D)
night (OH)
- the presence of a family member:
day (ChP-D),
night (state of emergency-N).

 The reactions of the system in each of the modes are as follows.

 In the mode "absence of the master - day" when attempting to penetrate: the security sensors 4 are activated, the signals from which are fed through the connection ports and the common bus 2 to the central control device 1, which activates the acoustic warning device 16, writes to the protocol, activates the device 17 - turns on the flashing light, activates the device 18 - makes an automatic redial on the "Protection" channel. When smoke is activated, fire sensors 5 are activated, the signals from which through the connection ports and the common bus 2 are fed to the central control device 1, which activates the acoustic warning device 16, activates the device 12 - disconnects the electricity (if appropriate) and activates the device 11 - turns off the gas, makes a record in the protocol, activates the device 18 - performs automatic dialing through the channel "Fire".

 When a gas leak occurs, the gas sensors 10 are activated, the signals from which are sent through the sensor connection port and the common bus 2 to the central control device 1, which activates the device 11 — switches off the gas, activates the acoustic warning device 16, writes to the protocol and activates the device 18 - auto redial on the basis of "gas leak".

 When a water leak occurs, water presence sensors 9 are activated, the signals from which through the connection port and the common bus 2 are fed to the central control device 1, which activates the device 10 — switches off the water, activates the acoustic warning device 16, writes to the protocol and activates the device 18 - Autodial on the basis of "Water leak".

 The issuance of commands to devices 10-18 is carried out by the central monitoring and control device 1 through a common bus 2. The command received through the connection port of each of the devices 10-18 is sent to the microprocessor 51. As a result, control signals (via the corresponding amplifiers) are sent to the executive device mechanisms 10-18. The protocol of the system is located in the RAM of the central control and management device 1. The protocol is maintained by the corresponding recording of the microprocessor of device 1 in the block of its random access memory during recorded events.

 In the mode "absence of the host" in the sub-modes "day" and "night", the main reactions of the system are similar to the previous mode. In addition, after the onset of the night mode (by timer), the presence of lighting (and / or audio) is simulated.

 In the "host presence - day" mode, when the "Alarm" button is pressed, the auto-dialing is performed on the "Alarm" channel of the multi-channel telephone line notification device, recording into the protocol, and activation of the acoustic notification device. When attempting to penetrate, a voice message is made, flashing lights, recording in the protocol. In the absence of a host reaction, after 2 minutes an automatic redial is made via the "Protection" channel, a voice message, a gas shutdown, activation of an acoustic warning device and recording in a protocol. In the absence of a host reaction, auto-dialing through the Fire channel is performed for 2 minutes. In the event of a gas leak, a voice message is made, the gas is turned off, the protocol is recorded and the Silent Alarm is turned on — the BEEPERa tone (buzzer signal source located in the control panel). In the absence of a host reaction, after 2 minutes an auto redial is performed via the "Gas leak" channel. When water leaks, a voice message is made, recording in the protocol and activation of the acoustic warning device. If there is no reaction of the owner, after 2 minutes an auto redial is made through the “Water leakage” channel and the water is turned off.

 In the “day” and “night” submodes of the “host presence” mode, the main reactions of the system are similar.

The transition from one mode to another is as follows:
- day / night - by the hour;
- absence / presence - according to the signal from the remote control when arming / disarming;
- owner / family member - according to the entered code of the owner / family member.

 Lighting control provides the inclusion of lighting along the path of a person and off with a delay of 30 s after he leaves the room. The task of this mode is carried out at the stage of system configuration.

 Room temperature control and regulator control on heating devices (convectors, underfloor heating, etc.) are carried out only in rooms with installed heating devices. In this case, the mode of maintaining the set temperature (including different for different rooms) and the mode of lowering and raising the temperature in the absence of people at night (or day) time are possible.

 The audio support provided by the system consists in playing out greetings and farewells (when leaving and arriving, respectively), maintaining a speech protocol about the events that have occurred (power failure, the onset of certain situations, the number of door rings during an absence, etc.), using a voice pager (according to the code of a family member, the messages recorded for him are played), as well as simulating a dog barking when a doorbell rings in the “absence” and “family member presence” modes.

 Commands entered from input-output blocks are divided into three types: setup commands, host commands, and work commands.

 The setup commands are executed when the system is turned on and is being set up. These include commands to configure the system for a specific set of devices, reconfigure the system after the system has been supplemented with new elements at the request of the user, test the system, check (simulate) the alarm button, set the date and time. These commands are executed when you enter the access code of the installer before turning on the system and are not available to anyone else.

 Host commands are executed by the host after entering the host code and include the following set of commands: setting / changing the host code, setting / changing the family member code, turning off / on devices, recording phones by channels in the dialer memory, recording audio messages, writing the address to memory auto dialer. These commands are executed by the master during the installation of the system and are updated as necessary.

 Working commands are executed by both the owner and family members after the owner code or family member code has been entered and includes the following set of commands: entering the host code, entering the family member code, reading the message protocol, arming the premises, disarming premises with security, alarm status reset, response to activation of the acoustic warning device (technical alarm reset). Work teams are executed daily.

 A report on the operation of the system is a protocol that contains messages about all situations that arise during the operation. Messages are recorded in the protocol about changing the operating mode, emergency situations, disconnecting devices, actions taken, phone calls of the dialer, etc. The protocol is designed for 128 messages. The user can read the protocol, as well as erase messages at any convenient time.

 In the process, the system performs a self-test, if a malfunction occurs in any device, it displays a message on the display screen and captures the event in the protocol.

The system, implemented mainly on the domestic element base, can have the following main characteristics:
maximum line length - up to 1000 m,
the maximum number of connected devices is 2000,
main power supply - 220 V,
emergency power supply - 12.6 V,

 The system is adaptable and expandable both in quantity and in types of external (controlled and / or controlled) devices.

 The block construction of the system allows the use of common and commercially available fire control sensors, which have a certificate of both domestic and foreign production (smoke, infrared, etc.), security (infrared, relay-reed switches, glass break sensors, touch sensors, for example, firms ADEMKO). One of the sensors may be an input call button. When sensors are connected to the corresponding interface, information is recorded in it that completely identifies the type and physical features of the sensor. The system recognizes it by the type of sensor and provides information processing corresponding to its physical characteristics.

 To control engineering systems, moisture sensors (one or more) are used, appropriately installed in places of the most probable leaks (near cold and hot water pipes on the floor and ceiling), gas sensors that record the excess of the permissible gas concentration in the air, temperature sensors (and / or humidity) of air. As a power sensor, a power relay is used in the power network.

 Devices 10-18 are valves with electromagnetic control for controlling the supply of water and natural gas, control devices for heating devices (electric thermoheads on heating devices for central heating, thermostats for controlling heating devices), devices for connecting any type of electrical devices (power sockets) equipped with remote shutdown.

 In addition, the system has a software-built-in timer clock located in the main console; an alarm clock with playing back a recorded message, which is located in the dialer and works under the control of the program, provides anti-scanning with an alarm and the transmission of an emergency message when an attempt is made to enter; The program located in the main unit conducts a self-test with the subsequent localization of defects and the transmission of voice messages to the owner.

 The central monitoring and control device can be made on the basis of a microprocessor type MCS51 with a synchronization frequency of 4-12 MHz. Three memory chips of type 24LC16A each with a capacity of 2K bytes are used to organize the program and data area, as well as to store an event protocol up to 128 messages. The MAX691 watchdog timer restarts the system in the event of a power failure.

 The input-output unit (remote) provides the input of programs into the system, an indication of current events, and the installation of operating modes of the system. The LCD display of the input-output unit is based on the DV1602 chip. The I / O block is controlled using an MCS51 type chip and one or three 24LC16A memory chips. On the board there is a path of a microphone pre-amplifier (microcircuit MC34119) and an output device of the conversational path. Two LEDs show the modes and status of the system, 16 keyboard buttons allow you to fully configure and monitor the system.
