8.3.2.
The type and rating of the terminator of the security system loop (resistor,
condenser and diode) are determined by the type of the receiving-control device,
with which the sensor is connected. Usually it is a resistor. The rated resistance of
this resistor should take into account the resistance of the actuating relay contacts
(≈10 Ohm), the lightning guard circuit (this resistor - 100 Ohm) and the resistance
of the security system loop (depends on the chosen cable type and its length).
8.3.3
. The contacts of the Rx blocking button («TAMPER») can be connected to the
receiving-control device with a separate loop. In this case the separate signal
indicates the
opening of the Rx cover. The second variant is to connect the
blocking contacts in series with the actuating relay contacts. In this case an alarm
will be registered by one channel of the receiving-control device at the relay
actuation
or at the opening of the Rx cover.
8.3.4 . The scheme of the sensor connection using the junction box «JB-15» is shown in
Figure 8.2. The contacts of the blocking button are connected in series with the
actuating relay contacts. The sensor receives a signal from the remote control (RC)
