Notes:
= Includes enclosure effects. The threshold can be factory set to provide optimum performance over a specific band of interest.
> The alarm threshold is proportionate to IEEE C95.1-1991 Standard and varies over the 2 to 30 MHz band. The threshold is 0.9% of
the H field Maximum Permissable Exposure (MPE) from 3 to 30 MHz and equal to 10% of the E field MPE from 2 to 30 MHz.
? The 3 dB intercept angle is >180 ° with the E field tangential to the mounting plane and >165 ° with the E field perpendicular to the
mounting plane.
@ The SMARTS circuitry will operate from -20 ° C to +65 ° C. Extensive thermal analysis indicates that, under worst-case conditions
(no wind, no shade), the temperature inside the weatherproof enclosure will be a maximum of 10 ° C higher than the ambient air
temperature. Therefore, the maximum ambient air temperature is 55 ° C.
A The fail-safe battery has a rated life of 5 to 10 years. It is recommended that it be checked annually during calibration and replaced
every three years.
B This is the equivalent of IEC Publication 529, Type IP66 or CSA Standard C22.2, No. 94.
C Other calibration frequencies available for narrow band applications. Contact the factory.
ALARM OPERATION
Condition J101 Output
Normal Operation Low
Test Circuit Opened High
Alarm High
Sensor Failure High
Enable Circuit Closed Low
External Power Failure High
Note:
The STATUS signal available at J101 provides >2.4 VDC
into a 24 k Ω load when “High.” The voltage drops to
<0.8 VDC when “Low.” Maximum sink current is 3 ma.
