2. MULTIPLE ENTRANCES
A. Ovation Controller Cabling
The following cabling must be run for a multiple entrance installation:
a. A 4 twisted pair cable
from the Ovation Controller to the MUI located in the first LIB housing,
as shown in Figure7. This cable can be up to 2500 feet in length. Each additional Ovation
controller must be wired to the corresponding unit number on the MUI.
NOTE: Belden 8757 for unshielded installation and Belden 9504 for shielded installations (or
equivalent) is recommended.
b. 2 conductor shielded cables
from each Ovation Controller to the 120 VAC outlets for the 12
VAC, 50 VA transformers supplied by Sentex (or a 13.5 VDC power supplies that you provide).
See Table 3 for the required wire size.
c. 2 conductor cables
from the Ovation Controller to the door strikes, magnetic locks or gate
operators for the 2 control relays on each controller.
d. 2 conductor cables
from the strike power supplies, if required.
e. Wiring for additional features
as required. See Part 9 for details of the cabling required.
