3.3.
The distance recommended from the axis of the detection zone up to guarding, building
walls and other nonmoving objects should be as follows:
80…200m - 1, 1 m minimum
25…80m - 0, 8 m minimum
10…25m - 0, 4 m minimum
3.4.
The detector generates an alarm when:
- An intruder crosses a detection zone (perpendicularly to the axis) at a speed of 0, 3…10
m/sec at his full height or bent (crawling through) with the minimum detection probability of 98 %;
- RC signal is given on Tx;
- Electromagnetic field influences on Rx for its masking. An alarm can be absent but in this
case the detector saves its availability.
An alarm is generated by breaking the contacts of an individual point opt electronic relay for
the time 3 sec minimum. This signal is sent from Rx by yellow and pink colored wires marked “NC”
(normally closed); “NC” (normally closed).
Note.
At the distance of 3-5 m from the supports on which Tx and Rx are installed, the
probability of the intruder’s detection who is bent (crawls through) is 98 % because a person can
move bent and pass below the detection zone.
3.5
. The detector generates a fault signal in the case:
- The absence of the signal from Tx
- In the absence of power supply or when the voltage drops below 9 V.
- Failure of Rx or Tx.
A fault signal is generated constantly (latching) till the same is rectified and indicated by
break in the contacts of an individual point optoelectronic relay indicated by yellow and pink colored
wires marked “NC”; “NC”.
3.6.
The dimensions of an individual point optoelectronic relay are: the maximum switching
current is 0,1A; the maximum voltage is 50 V; the maximum resistance is 100 Ohm in the closed
status (with the elements of storm protection).
3.7.
Removal/ opening of the back inspection cover of the Rx unit generate a tamper alarm. The
contacts of the tamper circuit are broken and this is reflected at the Rx unit through the green and grey
colored wires marked “TAMPER”, “TAMPER”. Contacts rating of this tamper circuit are: current up
to 0,2A at voltage up to 80 VDC.
3.8.
The detector power supply is: 9…30 VDC with a maximum pulsation of 0,02 V
maximum. The maximum current consumption is 35 ma at 24 VDC.
3.9.
The detector operation can be tested by applying 5…30 VDC signal at the RC on the Tx
unit. The RC is marked as “RC” (remote control) input of the transmitter. The duration of this test
signal is 1…3 sec.
3.10.
The detector doesn’t generate an alarm when:
- precipitations such as rain, snow, thick fog
-
solar radiation
-
the influence of wind at a speed of 30 m/sec. maximum
-
moving of the objects in the DZ (detection zone) of 5 m from Rx or Tx of the objects
with the linear dimensions of 0,2 m maximum (birds or small animals)
-
irregularities on the sector up to ± 0, 3m
-
snow without additional adjustment up to 0, 5 m
-
grass up to 0, 3 m
