Compatible External Sensors - Nice 1551 Installation Instructions Manual

All Nice gate operators feature an Inherent
Entrapment System (IES) (UL325 Type A) that
monitors the force on the gate during travel.
This system protects in both the open and
close direction and reverses on contact with an
obstruction. This IES system serves as one of the
means of entrapment protection.
External sensors must be used to protect against
entrapment at each location where an entrapment
zone exists. The minimum number of external
sensors required to enable automatic operation
of the gate operator is as follows:
 Swing Gates: One sensor in the Close direction
(provided the gate in the open direction
presents no risk of entrapment.)
 Slide Gates: One sensor in the Open direction
and one sensor in the Close direction.
The gate operator tests for the presence of these
sensors, and if the required minimum number
is not found, the operator will only run using
continuous pressure on an Open/Close button,
either on the controller, or an external device.
