59 Tempest®2400 2-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 synchronizaon 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. ZSync Technology applies only to the
2.4GHz model of Tempest. It is not present or applicable to 900 MHz
models. 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.
