Fig. 54: End-of-line resistor and door contact switch
1.
Connect the "RJ12 plug" door contact switch (Fig. 53/2) to door contact input
"5" (Fig. 52/5) as per Fig. 53.
The overall length of the RJ12 connecting cable used (0.14 mm
2
(AWG 26))
must be a maximum of 30 m (98 ft).
2.
Connect the "Terminating resistor" RJ12 plug (Fig. 53/3 or Fig. 54/1).
If there are any older, gray door contact switches (type 7320.530, Fig. 54/4),
note that a different end-of-line resistor from the one for the transparent door
contact switches is required:
Door contact switch End-of-line resistor
Type 7030.128 , transparent (Fig. 54/2) 1 k Ω
Type 7320.530 , transparent (Fig. 54/3) 1 k
Ω
Type 7320.530 , gray (Fig. 54/4) 22 k Ω
3.
Remove the pre-fitted end-of-line resistor (Fig. 52/13) when using the "RJ12
plug" door contact switch.
