INSTALLING AV102 INTERCOM UNITS IN PAIRS (e.g. In/Out gates)
.
Using the optional master/slave switching card Model 102PAIR1 Rev 1.1
IT IS IMPORTANT TO FOLLOW THE WIRING INSTRUCTIONS CAREFULLY!
OBSERVE POLARITY OF EACH CABLE CONNECTION (Where Applicable).
DO NOT CONNECT ANY POWER UNTIL INSTALLATION HAS BEEN COMPLETED AND CHECKED!
The audio cables to/from the AVPSU4 unit (which will be in the equipment room) should
be TELECOM TYPE CW1308 (4 unscreened twisted pairs).
The DC power cable from the V Out and Ground should be a
minimum
1mm
2
,
2 core
stranded
type.
The CALL SWITCH and ALARM cables may be any type (e.g. standard “alarm” cable).
Install the switching card in unit A and install cabling for unit A as specified earlier in this
manual.
We suggest that, in the case of an in/out application, you make unit A the unit on
the SECURE side of the gate
.
Using the same cable specifications as for unit A, install the cabling for unit B but note that
these cable only have to be wired back to unit A
.
COMMON CALL JUMPER
The switching card will output the call from each unit when the button is pressed. This is
done via on-board, clean contact (normally open) relays on the switching PCB.
In order to use the individual call outputs
, the common call jumper should be set to
"OFF" and the call outputs (A & B) should be wired individually (to “A CALL” and “B
CALL”). Refer to the drawing on page 10 labelled “Switching PCB”.
If required, both call outputs may be linked so that the unit will provide a single "common"
call output when either of the buttons is pressed.
In order to have a common call output
, the common call jumper should be set to "ON"
and a wire link installed between terminals 4 and 5 on the switcher PCB. The call output
then appears across terminals 3 and 6. Refer to the drawing on page 11.
INSTALLING THE MASTER/SLAVE SWITCHING CARD
Install the switching card in unit A (if not factory fitted), as described below.
