4. The standard cabinet is factory assembled and pre-wired. Wiring for power must be provided to the
cabinet, along with any associated loudspeaker and handset stations cables. Bring all field wiring into
the terminal blocks in the rear section through the cable knockouts.
5. Connect the individual handset stations (L1, L2, P, A) and the paging speakers (C, 8 ohm, 70 V) to
the terminal blocks in the wall-mounted rear section of the Model 10468-002 Central Cabinet. The
three rows of ten terminal blocks can support a total of 30 stations. Refer to Figure 4 for an example
of the typical terminal block wiring connections.
6. Make the necessary connections to the three terminal blocks located in the rear wall-mounted section
of the central cabinet labeled P OWER , A LARM , and I NTERFACE . Refer to Figure 4 and Figure 5 for
the wire color-coding. Their functions are as follows:
• TB11 (P
OWER ) provides connection of the 21 to 28 V dc negative ground power supply (35
amps maximum).
• TB12 (A
LARM ) is for remotely mounted alarm switches (normally open/momentary contact).
• TB13 (I
NTERFACE ) is for remotely mounted switches (normally open/momentary contact) for
telephone access, disconnect, and mode select.
N OTE : If the central cabinet is in a location where the equipment front panels can not be accessed,
remote auxiliary switches can be connected to perform the access, disconnect, and mode select functions.
Since the currents and voltages are very low, almost any kind of momentary, normally-open switch can be
used.
