Battery Charging Unit (BCU) Installation
Battery Charging Unit (BCU) Installation
The BCU provides power for the system during a power failure. The BCU connects to the Triad-S via the
connector on the bottom of the BKSU. The external gel cell batteries must provide 24V DC. This is generally
accomplished by connecting two 12 volt batteries in series. The BCU provides charging current to the
batteries during normal AC power operation at a maximum of about 0.5 amp. During battery operation, the
BCU discontinues battery operation if AC power is restored or the battery voltage is too low to maintain
proper system operation.
The time the system operates on batteries is dependent on several elements, including: battery charge state,
condition of the batteries, capacity of the batteries, and the system size (number of station ports). The
following chart gives the approximate backup time in ampere hours for two system sizes and different
battery capacities.
KSU Grounding
To ensure proper system operation and for safety purposes, a good earth ground is required. A metallic
COLD water pipe usually provides a reliable ground. Carefully check that the pipe does not contain
insulated joints that could isolate the ground. In the absence of a COLD water pipe, a ground rod or other
source may be used.
A 
#12 insulated AWG or larger copper wire should be used between the ground source and the KSU (BKSU
and EKSU, respectively). The wire should be kept as short as possible (recommended 25 feet or less).
1Remove about 1 112 inches of insulation from both ends. Attach one end of the wire to
the Ground Lug on the lower side of the Basic and on the lower side of the Expansion
KSU by inserting the wire under the lug screw, then tighten the screw securely.
2Attach the other end of the wire, as appropriate, to the ground source.
3Take a DC resistance reading and an AC volt reading between the chassis ground point
(cold water pipe) and AC ground (third wire AC ground). The limit is 5V AC and 5 Ohms
DC resistance. If a higher reading is obtained, choose a different chassis ground point
and repeat this step until a suitable ground point is found.

							Power Line Surge Protection
The AC outlet should be equipped with a power surge protection device or UPS. Systems using such devices
are more resistant to damage from power line surges than unprotected systems. Power line surges often
occur during normal operations and during violent thunderstorms,
Installation of a surge protector meeting the specifications described in the following paragraph may prevent
or minimize the damage resulting from power line surges.
The isolation transformer/surge protector should be: 
15 amp self-contained unit that plugs into a standard
grounded 
117V AC wall outlet. The wall outlet must be designed to accept a 3-prong plug (two parallel blades
and a ground pin). The protector should be fast and capable of protecting transients greater than 
200 volts.
Lightning Protection
The system provides secondary protection per UL 1459 specifications. Primary protection circuitry is the
installer’s responsibility and should be installed per the National Electric Code (
NEC).
KSU AC Power Plug
Before plugging the KSU power cord into the AC source (grounded, 3-prong AC outlet required), verify that
the power switch of the BKSU is off.
+Plug the KSU power cord into the AC outlet and turn the power switch on, The red LED on the MBU
illuminates.
PCB Installation
PCB Handling and General Installation
DO NOT install or remove any boards with power applied.
Power must be turned off prior to installation or removal of the PCBs. The system cards contain digital
circuitry which are extremely reliable, but can be damaged by exposure to excessive static electricity, When
handling 
PCBs, a grounded wrist strap should be used to protect the boards from static discharges. Also, use
common sense when handling 
PCBs. For example, do not place a PCB in locations where heavy objects
might fall on the PCB and damage components.

BKSU and Main Board Assembly
BKSU and Main Board Assembly
The MBU is installed in the BKSU at the factory before the shipment. The MBU contains a lithium dry cell to
maintain memory and real-time clock functions. The battery is soldered to the MBU and connected to the
circuitry by an ON-OFF dip switch 
(SW2). Make sure the dip switch SW2 is ON before database
programming.
Before programming the system, switch 
1 (SWl) should be placed in the ON position and powered off and
on to initialize the system database to default. Once the database is initialized, switch 1 
(SWl) should be
placed in the OFF position to protect the database. Shown below is the dip switch position functions:

Figure 2-5: BKSU Dip Switches
The MBU may be equipped with 3 daughter boards: MODU for modem access to the system, DTMF-4A for
DTMF receiver expansion up to five, and a MISU for two serial ports and a second music source.
Software for the system is contained on two chips labeled 
Ul and U2 in the Program Module Unit (PMU)
module.
The MBU provides miscellaneous features:
oOne external page port that is connected to transformers, providing a 600 ohm impedance.
+One music input that is connected to transformers, providing a 600 ohm impedance.
9‘Rvo independent dry relay contacts rated at 1 amp, 24V DC.
oA DTMF receiver.
These features are provided through the amphenol connector on the front edge of the CKIB installed in the
first slot of the BKSU. These features are controlled by system software.
Modem Unit (MODU)
The Modem Unit provides an asynchronous modem for access to the system database and remote
maintenance. The module is optionally installed on the BKSU 
(MBU) and includes a 9600 baud modem.

							The modem may be accessed from any station or CO. The MODU port is independent of the MISU RS232C
ports, enabling system database access, etc., without interrupting the SMDR output.
To install the MODU:
1Using a grounding strap, unpack the MODU from its anti-static bag in the packing box.
2Locate the CN6 connector (outlined) on the MBU.
3Locate the CNI connector on the MODU.
4Position the MODU so the CNI matches with CN6 on the MBU.
5Push the MODU onto its connector, making sure it is properly seated.
6Match the screw hole on the MODU PCB bracket with the screw hole on the base frame.
7Insert a screw and tighten the screws securely.
