2 3.3. Loudspeaker system with a combination of functions elektrosiren scoring and wire broadcasting Collective Farms-22m

Purpose of Collective Farms-22M.

Collective Farms-22M is designed to alert the population through a network of wires at Volyn speech.

The composition of Collective Farms-22M includes:

remote control equipment (PP);

intensive-switching unit (PCB) with a nominal capacity of 250 to 2000 watts;

ancillary equipment;

Horn speakers with remote switching.

Office of Collective Farms-22M can be done with PC control station via PUZS, CCD-2, or embedded control panel. The control circuit is shown in

PU is intended for remote control and monitoring of equipment Collective Farms-22M, has inputs for connecting microphones, tape recorders, and radio. PU and auxiliary equipment may be installed at a considerable distance from the PCB.

PKB is designed to gain information signals to the required pot in zhnosti, transfer it to the radio feeders with connected speakers and allows you to have up to 13 zones alarm and quickly choose PU any quantity. N Output voltage and PKB may 30,120,240 V. Frequency band 100-6000 Hz. The composition of PCB input is:

input block with 5 blocks amplifying power of 250 W;

localizer damage output lines;

power supplies with output voltage = 24 V, for power amplifiers;

UPS that is designed for power equipment voltage = 24 B-minus on the body, has rechargeable batteries and Charger of 220 V, 50 Hz, providing work for 0.5-2 hours PKB when disconnecting the power supply.

Input unit provides:

coordination with remote control, making commands and signaling ve d posts on PU status PKB and baselines;

acceptance and execution of external commands from the CCD-2 or P-164;

signal "Siren";

forming teams of inclusion and exclusion of street speakers;

adjust the input signals Broadcasting network and auxiliary input from AMC-2 or P-164;

light indication mode of the equipment.

By the composition of auxiliary equipment includes:

Hub Management (CG) that is designed for organizations managing multiple PKB (4,8,12) from one control panel, Fig. 2. 3. 4;

- Power switching and control (BCU), is designed to manage the existing radio broadcasting nodes with CCD-2, P-160, P-164, which in turn break the chain of speech signal wire broadcasting center;

- Block alarm messages (BTP) designed to work together with the Collective Farms-22M, incorporates electronic generator sirens (in the terminology of Emergencies and the international classification);

- Coupler with a computer (BUK), designed to control equipm Collective Farms Dr Nunn-22M with a PC via PUZS and CCD-2.

Disadvantages of Collective Farms-22M.

Disadvantages of Collective Farms-22M are:

- For equipment Collective Farms-22M should have heated the room, to the construction of feeder wire broadcasting to connect the outdoor speakers and their constant service during the operation;

- To lay phone lines (or physical lines) for each CCD-2 and their constant service during the operation.
