3.2 Principle of construction of the MTA

In accordance with the “Technical requirements for the design of fire protection of the medical rehabilitation center,” the project provides for the protection of all the premises with an analogue analog fire alarm system (ASPS) regardless of the area, except for the premises:

· With wet processes (showers, bathrooms, sinks, etc.);

· Ventilation chambers (inflow, as well as exhaust, not serving industrial premises of category A or B), pump water supply, boiler rooms, etc. for engineering equipment of the building, in which there are no combustible materials;

· Categories B4 and D on fire danger;

· Stairwells.

In accordance with paragraph 13.2.2 of SP 5.13130.2009, the maximum number and area of premises protected by a single ring or radial loop with addressable fire detectors is determined by the technical capabilities of the receiving and control equipment, the technical characteristics of the detectors included in the loop and does not depend on the location of the premises in building.

In accordance with clause II 11.2 of the NPB 110-03, the space behind the suspended ceiling in the corridors is protected by automatic smoke fire detectors in the presence of cables and NG-type wires with a total volume of combustible mass from 1.5 to 7 liters per 1 meter of cable line.

The analogue optical-electronic smoke detectors TC 806 E 1012 M 01, which react to particles of solid or liquid products of combustion and pyrolysis in the atmosphere, installed on the main ceiling, on a suspended ceiling and behind a suspended ceiling, are used as means of detecting fire in protected areas .

In the premises of the cooking shops on the 1st floor, installation of thermal analogue detectors TC 808 E 1051 V01 with a maximum response temperature of 780 is provided .

On escape routes and staircases, installation of MCP 5 A manual address detectors at a height of 1.5 m from the floor level is provided for on the wall .

The interrelation of ASPS with other systems, technological and electrical equipment of the building is provided by the formation of the following commands:

· To start smoke removal in case of smoke in the smoke removal area;

· To launch a warning system and evacuation management in case of fire;

· To disable general ventilation;

· Stopping and lowering elevators to the main landing floor.

· To unlock the doors to the access control system.

2.1. Characteristics of the equipment

2.1.1. The address receiving control fire appliance (ATCM) XLS 80 e includes a case with a display and a keyboard, a power source and a central processor board, two built-in fire alarm loops. Additionally completed:

· Stub extenders for two stubs - up to 3 pieces per device.

· RS- 232 interface module with galvanic isolation - 1 pc.

· Network module NGM - 1 pc.

The algorithm works XLS80e fully programmed. The case contains two 12V / 12 Ah rechargeable batteries. Control commands are entered from the built-in keyboard, the LCD display shows the system status, including descriptions of the monitored zones, outputs and modules. Data can also be entered from the keyboard of a personal computer (PC). Network module NGM  allows you to organize work on the Arc Net network with other panels.

· The processor of the “master” panel synchronizes clocks and calendars of the “slave” panels.

· Event memory becomes common memory for events of all panels with sorting in chronological order.

· Fire detection zones and exits (starters, sounders) receive a unique sequence number in the system as a whole and are displayed as elements of one large system. Also, each panel has its own unique sequence number in the system.

· Information from each panel on the Arc Net network is displayed on any other panel instantly without delay.

· Any panel can display system-wide events or just selected panels. Any panel can send its own alarms to any other selected panels.

· The interface to connect panels to the network Arc Net is intelligent and high-speed. It uses a modified RS485 protocol with a sync generator on both sides of each node. This means that any malfunction or loss of communication on any part of the Arc Net network does not affect other parts. In addition, the Arc Net network has a ring topology and in case of loss of communication anywhere, the system will automatically find an alternative route for delivering information from the other side of the ring.

· In the event of a fault in the Arc Net bus, the panels continue to perform their functions by switching to offline mode.

· Control passwords in the system are synchronized across the “master” panel.

· The command to turn off the buzzer, given by the user of one panel, is executed by all panels of the system. The command to turn off the sirens also works.

· The use of “sectors” allows for high reliability of fire detection and minimizing the likelihood of false alarms during various activities at the facility.
