Honeywell X-618 Installation Manual page 12

This cable is used to connect the DCS to the DA as well as the DCS to the loudspeakers in the
broadcasting zones. Shielded cables with a cross-section of 1.3mm
are recommended to connect the external sound source devices, such as CD/DVD players
and tuners.

DA standby power supply cable
The DA standby power supply cable specification is required to be the same as that of the
main power supply line.

Power amplifier audio input cable
Audio input cables are provided in the package containing the DA, but the lengths of these
cables are limited. If these cables cannot meet the requirements of the system wiring situation,
users need to obtain or create appropriate cables themselves. Please create such audio input
cables with the specifications as listed in Table 2.


Dry contact input/output cables and related external equipment (optional)
The necessity of dry contact connections depends on the system situation. If the DCS and
external equipment, such as three-wire volume controllers and four-wire single-channel
controllers, must be connected through dry contacts, this equipment and the appropriate
cables must be prepared beforehand.

Noise detector (optional)
When needing to collect environmental noise and automatically control the volume of
broadcasts, a noise detector and appropriate cables must be prepared. The maximum cable
distance between the DCS and noise detector is required to be no more than 250m, and
shielded twisted pair cables must be used.
