One protective sector may be formed by two beams. Then both Tx radiators and both Rx
receivers of beaming are directed to each other. An alarm from this sector is displayed simultaneously
under two numbers.
5.2.6
Several separate independent spaced protective boundaries can be organized.
5.3
Charger Structure & Operation.
5.3.1
Charger has eight independent charging channels of SB. Each storage battery is charged
irrespective of the discharge degree the rest of the batteries.
5.3.2
To charge a storage battery Rx (Tx) is connected to one channel of the charger, RC Rx is
connected to two channels simultaneously. Three chargers of the system provide simultaneous charge of
the storage batteries of all units.
5.3.3
Each channel of a charger is equipped with a
РС
4 socket to connect to a PC4 plug which
can be found on each Rx, Tx and RC Rx.
5.3.4
First the charger provides charging of storage batteries in the restricting mode of the
maximum charging current, then in the mode of charging voltage stabilization. The mode is chosen
automatically.
5.3.5
Each channel of the charger contains a network transformer, a rectifier, a voltage stabilizer
with the maximum current terminator and indicators of operation mode.
5.3.6
Each charger channel two indicator lamps: “NORM” (green) and “CHARGE” (red).
5.3.7
Luminescence of the “NORM” indicator lamp means normal output charging voltage of
the channel.
5.3.8
The “CHARGE” indicator lamp is switched during charging a storage battery up to
85…90% rated capacity.
5.3.9
During the system operation a charger can be used as mains power supply source for RC
Rx.

SYSTEM CONSTRUCTION
6.1
Rx Construction (fig.6.1).
6.1.1
Rx is dust-splash proof. It consists of 2 cylinders 3 and 5 connected with each other by a
tube 8.
6.1.2
In the lower cylinder 3 (hereinafter referred to as a storage compartment) there is SB 2. It
is accessible when bottom 1 is removed. In the upper cylinder 5 there are two receivers of beaming 7.
The lower one is fixed on base 9; the upper one is fixed on handle 6. The axis of the directional pattern of
the lower receiver of beaming coincides with a mark on hood 10. Near the mark there is a number of the
lower receiver of beaming (odd numbers from “1” to “19”). The directional pattern of the upper receiver
of beaming corresponds to the direction of the pointer on handle 6. On the handle there is a number of
the upper receiver of beaming (even numbers from “2” to “20”). Using handle 6 the upper receiver of
