NORTON
Enhances 5700 Series LEO Power Operators
Monroe,
NC -- An enhanced version of the 5700 Series LEO low
energy automatic door operator is now available from
NORTON Door Controls.
The device features a low energy electric motor that,
when activated by a switch or motion sensor, provides a
power assist to slowly open the door. A mechanical
closer then takes over and returns the door to the
closed position. A new inverter, door position ring and
built-in level have been added to the 5700 Series to
improve functionality and simplify installation.

The
inverter includes simplified terminology on the
adjusting pots to enable easy access and adjustments. A
selectable push and close feature senses when the hold
open time is not needed and allows the operator to skip
this cycle and close like a standard door closer. An
overload safety shut-off prevents motor/inverter damage
by timing out and shutting the door when a door
activation signal exceeds two minutes. A motor start
delay waits from zero to five seconds to activate the
operator, giving the locking hardware time to release.
The inverter accepts dual voltage input: standard
120VAC, 60Hz (current draw .6A) or optional 220VAC, 60Hz
(current draw .3A).
A one-piece design door position ring requires no tools
for adjusting the door position; the magnet can be
positioned with the touch of a finger.
The built-in level is standard on the back plate and
eliminates the need for hardware to confirm the unit is
correctly leveled during installation.
Product list prices are not affected by these changes.
