5.1 Control and receiving device.

The technical solution provides for the use of the Russian device of the automatic fire alarm and control system PPKOPU 01121241 "Minitronik 24." The equipment has been mass-produced since 2002. Developer and manufacturer of Unitest CJSC in Moscow.

The warranty for the device is 10 years. (SSPB.RU.UP001.B07093 and ROSS RU.BB02.H04164). Certificate validity period is up to 22.06.2011.

The device is designed for autonomous and centralized fire protection of small, medium and distributed objects. The device is based on the ideology of the most consumer-oriented - high information content due to additional indication of the state of the SH, the simplicity and ease of perception of messages does not require additional control panels.

The embedded algorithms of the device do not require programming, it is enough to turn on with the correct installation and the device itself will make all the settings, which makes it modern, reasonable, simple and accessible to a wide range of users.

Built-in control of all fire control circuits allows to control the warning system of type I, II and III according to SP 3.13130.2009 and control the smoke protection systems of buildings without additional control units, which significantly reduces the cost of building protection.

Automatic reexamination of fire detectors allows improving the reliability of fire detection and eliminating false triggers.

SCP provides:

- reception of information on 24 alarm loops on penetration, fire and malfunctions, as well as signals from sensors of engineering systems;

- alerting the duty personnel about the events with the help of light and voice messages, as well as to remote warning devices and PCP;

- issuing commands to smoke removal and warning devices.

Firefighters are double-threshold, which makes it possible to distinguish the operation of one or two fire detectors in the loop and to generate signals "Attention," "FIRE," as well as to recognize the operation of sensors of building engineering systems (normally closed contacts) included in the same loop (for monitoring the position of DD valves).

SCP provides power supply to active 24V fire detectors at total consumption current not more than 3 mA.

If necessary, the device can be protected from unauthorized access to control using electronic "Touch Memory" access keys.

When working with self-test smoke detectors ONE DOMA2 ® IP 21290, in addition to the main signals "Warning," "FIRE," the device generates a signal "Message" informing about the detector malfunction or dust.

5.2 Self-test smoke detector.

IP 21290 ONE DOMA2 ® - smoke fire detector with automatic serviceability check. Designed for early detection of fire in the protected room and output of "Warning," "FIRE" signals to the SCP. If the smoke chamber is dusty and/or any node fails, the detector outputs the signal "Fault" to the SCP. "Message" signal is generated on "Minitronik 24" SCP at dusty and faulty detector with identification of faulty detector by alarm loop and by signals of detector LED.

Constant measurement of the optical density of the medium, (digital signal processing) and self-diagnostics of all detector units allows increasing the reliability of the alarm system, improving the reliability of fire detection at an early stage, and eliminating false positives.

The detector is provided with dust compensation of the smoke chamber, which allows to extend the service life of the detector between services. Separate indication of dust and malfunction on the detector indicator is provided.

Replacement of the detector does not require reprogramming of the system.

Early detection of faulty self-test detectors allows you to constantly maintain the automatic fire detection system in working condition with the guarantee that the system is operational.

5.3 Fire detector thermal IP 1035/2A1 * * with LED and NR contacts

The announcer fire thermal SP 1035/2A1 ** is intended for detection of the fire which is followed by allocation of heat with a temperature of operation of 54 wasps and automatic switch-on of a signal "Attention" and "Fire" from one or two announcers in SS respectively.

5.4 SMS message board "PPS2."

To exchange information with the PCT on-line using mobile cellular communication. Using the smsmessage, you can write to the memory of the module phone numbers 8 and set them allowed operations and security areas. The following commands are possible: cancel the alarm, turn off the siren, put/remove the area from the guard (all at once or one at a time), query the condition of the loops (normal, not normal), control the built-in relay to turn on any equipment (for example: open the door, turn on the heating, pump for watering, etc.). SMSmessages are deployed to show where, and when happened with specific names of the premises, And, the teams consist of one or two letters .

5.5. Security alarm.

Detectors used to protect an object from unauthorized access use various methods of detecting violators.

To protect the doors of the premises, magnetic contact detectors of the "SMK" type are used.

To protect the premises from unauthorized access, infrared motion detectors of the "VOLUME" type are installed.

It is possible to use detectors in particularly critical rooms for the protection of individual objects (metal safes) that respond to a change in the electric capacity of these objects of the "TANK" type. It is recommended to install alarm detectors of "BUTTON" type in the rooms for the attack signal output.

SIRENA sounders are selected for the fire alarm system.

Main design solutions for equipment protection and placement.

All rooms except those with wet processes shall be protected by automatic fire alarm. To detect fire at an early stage of fire, self-test smoke detectors IP 21290 ONE DOMA2 ® are used. Heat fire detectors with NR contacts and LED IP 1035/2A1 * * are installed in the kitchen room.

One detector shall be installed in each protected room in accordance with Item 13.3.3 of SP 5.13130.2009. At the same time, the requirements of the Code of Rules for the area protected by one detector (not more than 85 sq.m.) must be met.

In case of visual detection of fire and output of "FIRE" signal on "Minitronik 24" SCP, manual fire detectors of IPR-I are provided. The installation is provided by evacuation routes, on walls with free access to the detector. The height of the installation from the level of the clean floor to the center of the detector is 1.5 m. The distance between the detectors does not exceed 50 m.

To more accurately address the fire location, it is envisaged to use a multi-slot automatic fire alarm system, each loop of which protects a separate room. This facilitates the search for a triggered detector and allows you to quickly take measures to extinguish fire in the initial stage of fire development.

Total number of fire alarm loops = 18. The reserve for the informative capacity of the device is 25%.

Connection of fire alarm loops with smoke and manual fire detectors is carried out by cable in PVC shell and PVC insulation - KSPV 2x0.5 to PKP device "Minitronik 24." Cables are laid in the electrical PVC box. The number of fire detectors in one loop does not exceed the permissible current consumption specified in the technical certificate on the PKP "Minitronik 24."

Installation and installation of fire detectors shall be carried out in accordance with the design, requirements of standards and instructions for equipment.

The device is placed on the wall of the security post in a place convenient for visual inspection and use, but taking into account paragraph 5 of SP 5.13130.2009. Controls are protected from unauthorized access to the device by using a reader and Touch Memory access keys.

A BIAL/S alert is installed above the device. RIP12 is installed for power supply of the device (refer to 01) with battery 7a*ch. Power supply of RIP12 (refer to 01) is carried out from the electric board, with separation into a separate group and a single-band automatic switch installed in the OPR4 box. The box is installed next to RIP12 (Fig. 01).

6. Principle of automatic fire alarm system operation, interconnection with warning systems and smoke protection automation.

Security and fire alarm loops are guarded around the clock and cannot be removed.

In standby mode the green LED "Standby mode" is ON on "Minitronik 24" SCP.

When one smoke fire detector is activated in any SBS, the SCP reboot (resets the detector by power and restores it), and when the detector is activated again in the same loop, the device enters the "Attention" mode. By this signal the LED "Warning" is illuminated in red, the LED indicating the number of the activated alarm loop starts flashing in red and the open collector of the "Warning/Fire" device is turned ON. "BIAL" light annunciator connected to OK flashes near the device.

When the second automatic fire detector or manual fire detector operates in the same SBS, the device enters the "FIRE" mode. Red indicator "FIRE" is ON, LED indicating activated alarm loop is ON in red. The "Fire" relay of the device and the relay of the PR-2 module are switched on according to a pre-established algorithm.
