  This shemka to Vicomm could
respond to the call and picks up the receiver.

  Signal "ON_LINE" - control the line
("Tube" removed / put).
Connected on 5-th digit of the port # FE
(12 output m / s 35 on the circuit Scorpion)

 "Ring" - Ring Tone. In the presence of
Ringing earthed.
Connected on 5-th digit of the port # FE.
(Signal DSR, concluded on b24 control port)

Relay P1: RES-15 passport RS4.591.004

          RES-10 paspotr RS4.524.312

Relay P2: RES-32 passport RF4.500.341

          RES-22 passport RF4.500.129

  If the relay P2 is not triggered until the end
the first alarm call, should be replaced
capacitor C1 to the other with a capacity of
1.5 - 2 times greater, or use the relay with
lower current operation.


  Diode bridge: any silicon diodes
reverse voltage of not less than 200V and the line
current of 300 mA, for example KD105B, D226V, KD205G
or diode assembly.
