Notes:
= Peak to peak. 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.
(Controlled Environments)
? 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 rated life is two years. It is recommended that this battery be replaced annually during calibration.
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 Other calibration frequencies available for narrow band applications. Contact the factory.

Normal Operation Light flashes every 40 sec. Low
Low Battery Alarm chirps, light flashes Low
TestButtonDepressed Steady sound and light High
Alarm Steady sound and light High
Main Battery Failure No sound or light High
Sensor Failure Steady sound and light High
CONDITION J2 INPUT
Normal Operation Open Circuit
Alarm Disabled Short Circuit
People Present ! Open Circuit
No People Present ! Short Circuit
Notes:
The STATUS signal available at J1 is a voltage source that
provides >2.4 Vdc into a 500 k Ω load when “High.”
The voltage drops to <0.8 Vdc when ”Low.” The load
impedance can be reduced to 24 k Ω providing that
the Main Battery Failure signal is not required.
Jack type is 3.5mm miniature phone.
J2 Input: Normal condition is an open circuit.
A short circuit (<100 ohms) disables the SMARTS.
Jack type is 2.5 mm miniature phone.
! When used with the Model 8808 Personnel Sensor.
