The ZoneMaster PRO SM Series of products is
designed for the optimum control of surges.
Using combinations of SAD and Large Block
MOV modules, the unit provides exceptional
protection
performance
for
sensitive
equipment. The ZoneMaster PRO SM provides
multiple levels of redundancy with the SAD
primary stage, backed by high current capacity
of the MOV stage.
The ZoneMaster PRO SM Series has the
option of line to neutral protection only. This
option is required by radio manufacturers who
specify that there will be no neutral to ground
connections or components after the shelter
(or building) neutral-ground bond point.
In addtion, multiple SAD modules are available
for critical sites. The ZoneMaster PRO 200
SSM model comes with two (SS) SAD modules
for extremely critical sites providing the lowest
let-through voltage possible.
Each module has a patented dual fusing design
that provides both thermal and overcurrent
protection at the module level. Dual circuits in
each module ensures redundancy and
continued protection in the event of a surge
that exceeds the module’s capacity.
The integrated fused disconnect is a standard
item in all ZoneMaster PRO products. This
provides an extra safety feature for the
servicing of the unit and complies with NEC
requirements, thereby elevating the kAIC
rating of the unit.
remote installation and includes a test switch
function and a switch to silence the audible
alarm.
An standard power filter is available which
eliminates a broad range of load or line
generated high frequency noise. This UL 1283
Listed filter module has a noise attenuation of
75dB at 100KHz-100MHz and will attenuate
6kV transients down to a mere 200V without
the support of other surge components.
ZoneMaster PRO units are tested as per
ANSI/IEEE C62.41 and C62.45.
The multi-mode surge counter actually counts
the number of times a surge current is
discharged when a transient is suppressed;
many competitive products count only voltage
impulses. These counters show the number of
transient
voltages
exceeding
the
manufacturer’s set limits and can even be used
to identify which phase has received the most
surges - an industry first.
Remote monitoring is facilitated by the optional
audio/visual alarm annunciator panel which
offers clear indication of the status of
the ZoneMaster PRO unit and a
flexibility not offered by built-in
products. This panel can
be mounted either
adjacent to the
ZoneMaster
PRO or in a
AC Power
