OPTIONAL BATTERY BACKUP and
LOW BATTERY INDICATOR LOCATION
(Figure 3)
All Models
Install the single-gang electrical box in an area that is convenient
for visibility of the Low Battery Indicator Light. This can be located
either close to the fixture or in a remote area such as the mainte-
nance area or engineering room.
• The battery backup will supply power to a maximum of eight
flush valves for an approximate three-day period during a
power failure.
• The Low Battery indicator will come on when the batteries
have reached a “caution level.” The Flusho meters will function
when the light is illuminated until the batteries are completely
discharged.
• The Low Battery light will illuminate even if the main power has
not failed but the batteries have dropped to the “caution level.”
INSTALLATION
STEP 1 – Install Receptacle
(Figure 4)
Install Receptacle for the Zurn Power Converter in a con venient
location. An optional mini junction box (P6000-MJ) is recommended
to distribute power to each sensor loca tion. It is also recommended
that brown wire be used for the positive (+) of the supply and blue
wire be used for the negative (-) of the supply. This matches the
sensor and actuator wire colors.
NOTE:
One Zurn Power Converter can operate as many as eight
Automatic Sensor equipped Flushometers. The Power Converter
is supplied with a six-foot cord. If addi tional wire is needed from
the Power Converter to the Flushometer(s), use #18 AWG for this
(by others).
Do not supply power
to the Power Converter until
installation of actuator, sensor and Flushometer is completed and
checked.
Proper polarity must be observed or damage to one
or all components will result.
