9.3 When deploying the system the following procedures are fulfilled at the same time:
−
poles are installed according to procedure 8.2;
−
Tx (Rx) power supply is set and switched on according to procedure 8.3;
−
Rx (Tx) is positioned according to procedure 8.4;
−
sectors are set to standby mode and their operability is checked according to procedure 8.8;
−
sectors are set to “Automatic control” mode according to procedure 8.9.
9.4 Sectors are deployed in pairs; both sectors of this pair are supported by one Rx.
9.5 Sectors are deployed by three people. One person takes RC Rx with him; hereinafter this person
is referred to as an operator.
9.6 The procedure of deployment is given dered in fig. 5.1 for sector 1 and sector 2.
9.7 Arrange three poles of sectors 1 and 2 according to the draft of a protective sector. Mount two
Txs and Rx1-2 (they are mounted by an operator), position them and switch on Tx power supply. Switch
on RC Rx power supply (a spike antenna must be mounted on RC Rx).
Switch on Rx 1-2 power supply, reset check alarms (see item 5.1.13), and after 30 sec. is over
(damping time) check the sector setting to standby mode. The operator must be at the distance 2 m
minimum from Rx1-2and he as well as the rest technicians must not be in the detection zones of
deployed sectors. Configuration and size of a detection zone of each sector of the system are given in fig.
9.2.
Note.
If first Rx power supply is ON, then Tx power supply is ON, the damping time lasts up to 4
minutes (see item 8.8.1), after that reset all alarms including two check ones.

If the sector length is reduced the detection zone becomes narrower.

9.8 Set sectors 1 and 2 in “Automatic control” mode according to procedure 8.9.
9.9 Check the operability of sectors 1 and 2 by check passes in position “to one’s full height” or
“having bent”; the operator checks the indication of alarms on RC Rx. If the results are positive, the
technicians start deploying two next sectors of a protective boundary.
