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,...

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...

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

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....
