Dry Contacts
This feature provides switching for
the operation of a solenoid valve
and/or remote alarm. When the
lamp is not operating properly or
the UV sensor signals that the UV
output is low, the contacts will
open causing the solenoid to stop
the water flow and/or a remote
alarm to sound. The dry contact
remains open if the lamp has been
in operation for 12 months or
more.
Remote Options Cord
must be ordered to use Dry
Contacts.
UV Sensor
The UV sensor measures the
amount of UV light reaching it,
allowing the system to monitor
whether the intensity is above the
minimum required for proper dis-
infection. The sensor is factory
calibrated and is not field
adjustable. See your dealer for
proper system sizing.
