IMPORTANT SAFETY INFORMATION
Monitored Entrapment Protection Requirements
IMPORTANT: MONITORED PROTECTION MUST BE INSTALLED
•
REQUIRED BY UL 325, an approved MONITORED entrapment protection sensor is
REQUIRED to be installed in all areas accessible to potential entrapment and pinch
points.
•
For Slide Gate Operators, a minimum of two monitored entrapment sensors are required to
be connected as follows: Either one to the UL terminal and one connected to the Re-Open
terminal, OR two monitored devices connected to the UL terminal, one for EACH DIRECTION
of travel.
! An external sensor connected to the “Re-Open” input terminal will protect against
entrapment ONLY in the closing direction.
•
The installed sensor MUST be “10K Resistor Based”.
•
You may connect up to FOUR monitored sensors, wired in parallel, to either the “UL”
and/or “Re-Open” terminals, for a total of 8 monitored sensors.
•
Failure to install the required monitored entrapment protection sensor(s) may render
the gate operator INOPERABLE. The gate can be moved manually. Refer to page 7.
•
Consult the installation manual of the sensor for detailed information about the usage,
installation and maintenance.
•
Use only UL Recognized Component Edge Sensors and Photoelectric Sensors. Refer to
pg 3.
SLIDE GATE ENTRAPMENT ZONE – Locations between a moving gate and a counter opposing
edge or surface where entrapment is possible up to 1.8 m (6 ft) above grade. Such
locations occur if during any point in travel the gap between a moving gate and fixed
counter opposing edges or surfaces is less than 406 mm (16 in).
! WARNING! Not Following these instructions may cause severe injury or death.
