allow unprecedented access to information such as lamp lifetime, message 
history and UV intensity display. 
The Hallett 15xs can show remote status: Be alerted to any change in system 
status immediately in any room with the optional Remote Monitor. The monitor is 
a handheld wireless device that can be placed in a convenient location to provide 
operational information about the Hallett.

minerals on internal components. The purge valve also eliminates nuisance 
alarms from changing water transmittance conditions.

stopped via external device; available are 4-20mA and RS 485 outputs for UV
