in case of exceeding the systemic alarm thresholds;

in case of exceeding of a subrange limits.

1.2.11.1 Sound alarm parameters:

 sound signal frequency in the range of ...................................... 1000 to 3000 Hz;

 sound pressure level:

at 40 cm distance from the ear ........................................... no less than 80 dB;

at 30 cm distance from the ear ........................................... no more than 100 dB;

1.2.12 The dosimeter provides automated recording of

its memory at the fixed time periods. The maximal number of records should not be less than

1900. Time period of archive records is established as follows:

with 1 second step for periods of 1 to 60 seconds;

with 1 minute step for periods of 1 minute to 1 hour;

with 1 hour step for periods of 1 hour to 18 hours.

1.2.13 In case of the uncharged (absent) accumulator batteries, the information recorded

in the nonvolatile dosimeter memory would be preserved for 5 years at least.

1.2.14 Electric power supply is provided:

for the dosimeter – by three accumulator batteries of no less than 280 mA/h capacity

each with the total supply voltage of no more than 4.2 V;

for УС-05С, КЗУ-27 – by AC single phase mains of

frequency.

1.2.15 КЗУ-27 provides full dosimeter battery charge within.......no more than 12 hours.

1.2.16 Electric power consumed by the dosimeter together with УС-05С and КЗУ-27 is

no more than 50 VA.

1.2.17 The climatic design is TH3 for the dosimeter and TH4.1 for УС-05С and КЗУ-27

on ГОСТ 15150-69.

1.2.18 Margins for external climatic factors on ГОСТ 15150-69 for the dosimeter, УС-

05С and КЗУ-27 in operation are as follows:

working temperatures:

for the dosimeter ............................................. minus 20 to +50 °С

for УС-05С and КЗУ-27 .................................... 0 to +45 °С

maximal relative humidity....................................... up to 98 % at +35 °С

atmospheric pressure.............................................. 86,6 to 106,7 kPa

concentration of corrosion-active agents corresponds to atmosphere type III, the

outdoors concentration of corrosion-active agents is as follows:

Substances

Chlorides

Sulphates

Sulfurous gas

Nitric oxides

For УС-05С and КЗУ-27 the concentration of corrosion-active agents is allowed to be

equal to 60 % of the specified values.
