BFD1 Door Controller Jumper Settings
Camera Terminator
There is a separate jumper for both video Camera inputs. This has three settings, 75R for
terminating coaxial cable, 100R for terminating twisted pair Cat5 cable and None for use
when passing the cable on to another device or controller.
Video Gain Control
The “Video Gain” jumper on door controllers should always be set to “0” unless directed by
‘Bell System Technical Support’. This jumper is only required on some systems with very
long cable runs, camera to apartment station well in excess of 150m. Inappropriate use of
this jumper with short runs will cause picture problems.
Reassurance tones
DDA reassurance tones for “ringing” and “door open” are available at the door panel. The
volume is adjustable from 0 using the volume control on the BFD1 controller PCB (see the
diagram on page 31).
The lock tone is always active and the ring tone is activated by placing a jumper between
pins 5 & 6 of the “Prog-6” pin header on the BFD1 controller PCB, the jumper is stored
between pins 1 & 2.
