2. LIB CONNECTIONS
IMPORTANT NOTE
If the Ovation system is used in conjunction with an alarm system, the telephone line MUST
encounter the alarm system first, then the RJ71Cs, and then the Ovation Controller (see Figure
13). If the system is not connected in this order, it will cause erratic problems with both the
alarm and Ovation systems.
Figure 13. Connecting Alarm and Ovation Systems.
1. RJ71C Connectors
1.
Remove the shorting block from the first RJ71C connector.
NOTE:
Keep all shorting blocks with their RJ71C connectors. Should the LIBs become damaged
or disconnected, reinstalling the shorting blocks on their RJ71C connectors will restore
normal telephone operation.
2.
Connect a 50 conductor cable with a 50 pin connectors from the associated LIB to the RJ71C
connector block.
•
Fifteen foot connector-end cables are available from Sentex.
•
Longer connector-end cables may be special-ordered from Sentex.
3.
Repeat steps 1 and 2 for each RJ71C and associated LIB.
IMPORTANT NOTE
If any residents have 3-way calling, either their 3-way calling service or the optional Ovation
call-waiting feature must be discontinued. Otherwise, when call-waiting is activated, the
Ovation will trigger the 3-way calling feature and the tenant will be connected to a dial tone. To
discontinue call waiting for a single resident, see the enclosed manual entitled "Instructions For
The Programming And Use Of The Ovation System".
2. LIB Power
1.
Connect the power cable from the supplied 12VAC transformer (or 13.5 VDC power supply you
provide) to TB2 (IN) on the first LIB.
2.
Connect TB1 (OUT) of the first LIB to the TB2 (IN) of the next LIB in the chain.
3.
Continue until all LIBs in a cabinet are connected.
CAUTIONS
1.
Do not apply power until all connections have been made. When power is applied to the
LIBs, all LIB POWER indicators should light (see Figure 14).
2.
The Ovation, door strikes, and LIBs must each be powered by separate transformers.
3.
Do not overload LIB transformers by connecting more than one cabinet (10 LIBs).
