 Signal "ON_LINE" - control the line
("Tube" removed / put). Connects
5-th digit port # FE (1912 output m / s from 35
scheme Scorpion) (15 m output / 35 to
scheme KAY v1. xx)

 "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)
(5 output m / s 37 (KAY) to dig out of GND)

 Relay R1:
 RES-15 passport RS4. 591. 004
 RES-10 paspotr RS4. 524. 312

 Relay R2:
 RES-32 RF4 passport. 500. 341
 RES-22 RF4 passport. 500. 129

 If the relay P2 is not triggered until after the first alarm 
call, replace the capacitor C1 to the other with a capacity of 
1.5-2 times higher, or use the relay to the lower current 
operation. 

 Diode bridge: any silicon diodes
reverse voltage of not less than 200V and 300 mA forward 
current, for example KD105B, D226V, KD205G or diode assembly 
(KTS407A, KTS402/405, etc.).
