15. Remove the speaker grille — Carefully remove the grille from the front of the CS 3T.

NOTE: Grille hooks are provided for grille removal, if needed.

16. Attach the speaker wires to the captive screw connector —

ATTENTION:

• Do not tin the wires. Tinned wires are not as secure in the connector and

could be pulled out.

• Ne pas étamer les câbles. Les câbles étamés ne sont pas aussi bien fixés

dans le connecteur et pourraient être retirés.

Number of Wires per Connection Point Maximum Wire Gauge

Figure 14. Wiring Multiple Speakers in Parallel

In the parallel configuration, all of the speakers downstream of the one being tested

continue to function even when it is disconnected. This is especially useful in

installations where the system can never be completely down, such as in a hospital

setting.
