3.5 The range of radio channel operation from the most remote Rx to RC Rx in the open area is up to
1000m.
3.6 The radio channel operability is controlled automatically for each sector set to “Automatic
control” mode.
3.7 RC Rx provides the following types of display:
-
digital (semi-segment indicators);
-
positional (LEDs) – constant illumination or generation of periodic sequence;
-
audible - generation of periodic sequence.
3.8 There are two relay outputs in RC Rx to generate:
-
a generalized alarm;
-
a combined trouble signal (AC, BDC)
Alarm time is 2 sec. minimum.
Relay output characteristics:
-
contact resistance in the closed state is 20 ohms maximum;
-
switched current is 0,1 A maximum;
-
voltage is 50 V maximum.
3.9 Power supply of:
-
local equipment (Rx, Tx) – 6
±
0,9 V (storage battery);
-
RC Rx – 6
±
0,9 V (SB) or via a charger from 220V mains;
-
charger– alternating voltage 50Hz 220V

%.
3.10 The system controls and displays storage battery discharge of each unit of Rx and RC Rx on RC
Rx.
3.11 Charger specifications:
-
output charging voltage of the channel in the voltage stabilization mode – (6,83 + 0,07)V.
-
maximum charging current of the channel in the current stabilization mode is 1,15
А
maximum.
3.12 Time of the system operation from storage batteries without their recharge:
-
at the temperature 20
˚
С
– 7 days minimum;
-
at the temperature 0°
С
– 5 days minimum;
-
at the temperature -40
˚
С
– 2 days minimum.
3.13 The system is electromagnetic interference proof.
3.14 The time of the sector availability for operation after power supply is on (equal to the time of Rx
damping) is 4 min. maximum.
3.15 Time of availability for operation after an alarm is generated is 20 sec. maximum.
3.16 Time of the system deployment (20 sectors) is 50 min. maximum.
3.17 Time of the system displacement (20 sectors) is 50min. maximum.
3.18 Maximum time of SB charge is 12 hr maximum.
3.19 Rx, Tx and RC Rx units of different systems
are not interchangeable
.
