59 Tempest®24 00 4-Channel Wireless Intercom System
Connec ng Mul ple BaseSta ons
Tempest BaseSta ons may be used together to form large wireless
systems, and may include external wired intercom systems. Intercom
audio for any or all channels can be linked across mul ple BaseSta ons.
Audio from one BaseSta on can be passed via a 2-Wire connec on
to another BaseSta on, if they are to share a single channel of audio.
Through this method, many complex combina ons of intercom channels
can be achieved.
All RF devices have the poten al to cause interference. Therefore,
Tempest o ers two synchronizatoin op ons, Accu-Sync™ and ZSync™,
that are designed to minimize poten al interference when using
mul ple BaseSta ons.
Accu-Sync is included with every Tempest BaseSta on and uses the
Accu-Sync connec ons on the back of the BaseSta on to synchronize
mul ple BaseSta ons together.
See the Accu-Sync sec on on for more
informa on on using Accu-Sync.
Zero Sync (ZSync) technology has been developed to enable Tempest’s Seamless Roaming feature as well as greatly
enhance the performance of non-roaming mul -BaseSta on Tempest installa ons. The ZSync technology provides a more
sophis cated form of BaseSta on synchroniza on over the older Accu-Sync technology. To u lize ZSync technology either
a Zero Sync Generator or a Parallel Zero Sync Generator is necessary to act as the source of the ZSync signal. These devices
are sold separately. All Tempest BaseSta ons con nue to support and provide Accu-Sync synchroniza on signals. It is,
however, strongly recommended that ZSync technology be used whenever there is a mul ple BaseSta on con gura on.
Tempest includes a Master Mode which provides required audio power when only Tempest BaseSta ons are linked without
external intercom.
See the Master Mode sec on.
A mul -base system will generally u lize Tempest Remote Transceivers to distribute the wireless signal, some mes
extending the number of users by overlapping the wireless coverage area, and some mes extending the wireless range
with the iSelect Roaming feature. In this applica on, always try to separate antennas by at least 10 feet whenever possible.
A 4-Wire matrix intercom system may be con gured to connect to mul ple Tempest BaseSta ons so that all share the
same channels. Con gure each BaseSta on individually as described in 4-Wire (Matrix) Intercom Interface. The following
informa on relates to mul ple BaseSta on con gura ons without a matrix system.
If intercom channels are connected across mul ple BaseSta ons without connec on to an
ac ve 2-Wire intercom, one of the BaseSta ons must be placed into Master Mode.
If mul ple BaseSta ons are linked on a common audio channel, each BaseSta on must
be nulled separately. Null one BaseSta on at a me.
