4 Operation and installation Operation and installation Location Options Mounting the SMARTS II Basic battery operation External power supply Alarm threshold adjustment Zeroing procedure Test button Remote alarm indication 4.10 The ENABLE feature 4.11 Remote test 4.12 Low battery indication 4.1 Location The location where you mount the SMARTS II depends on many factors.
4 Operation and installation Alarm Indications – either the internal audible and visual alarm indication and/or a remote indication can be used. External alarms require a cable connection. Remote Test – available with a cable connection. Enable – alarm operation can be inhibited when people are not present during high power operation.
4 Operation and installation 5. Put the battery in place into the compartment. 6. Replace the battery-compartment cover and finger-tighten the four captive screws. It is important that the screws are tightened sufficiently so that the cover slightly compresses the EMI gasket. 7.
4 Operation and installation 8. Mount the monitor in the desired location using the holes in the mounting brackets and screws suitable for the surface that the monitor is being mounted on.

4 Operation and installation Alarm Threshold 10 % 25 % 35 % 50 % 3. Replace the battery compartment cover and finger-tighten the four captive screws. It is important that the screws are tightened sufficiently so that the cover slightly compresses the EMI gasket. 4.7 Zeroing procedure It is possible to check the Zero setting and adjust it if necessary.
4 Operation and installation 4.8 Test button See 3.1 Test button 4.9 Remote alarm indication When the SMARTS II detects radiation at its preset alarm threshold or higher, an electronic signal is provided at the STATUS line (pin 4) to activated various user-supplied remote circuitry Alarm status can be detected remotely by using the STATUS signal, the RECORDER output level, and/or the STATUS relay (SPDT)
4 Operation and installation 4.10 The ENABLE feature To avoid the alarm indication being on constantly, the ENABLE input can be used in situations where the standard operating procedure produces RF fields above the alarm threshold and exposure to people is possible.
5 Determining location Determining location This chapter include points to consider when choosing the SMARTS II monitoring location. Overview Factors determining area coverage Preferred location Alternate locations 5.1 Overview The factors that determine when a SMARTS II monitor will activate its alarms include: ...
5 Determining location 5.2 Factors determining area coverage Energy sources, either purposeful emitters such as antennas, or unintentional emitters such as waveguide leaks, can be omnidirectional or focused in one direction. Field strength (power density expressed in mW/cm2 or W/m2) drops off rapidly with distance from the source. In the far field, field strength follows the inverse square law, i.e., at twice the distance there is one quarter the field strength.

5 Determining location Mounting a SMARTS II further from the energy source than people will be. Although it is possible to use a SMARTS II in this application, it is risky. In order to use this approach successfully, it is important to calculate the relative energy levels that the monitor and people will be exposed to based on the distance from the energy source to the monitor and the distance from the source.
