International registered trademark n. 2.777.971
Starting on Jan. 12, 2016, new UL 325 changes take effect, bringing a series of new mandates for the gate operator
industry. Here’s a quick guide to the key modifications.
1. Entrapment-Protection Devices. Gate operators are required to have a minimum of two independent means of
entrapment protection where the risk of entrapment or obstruction exists. A manufacturer can use two inherent-type
systems, two external-type systems, or an inherent and an external system to meet the requirement. However, the
same type of device cannot be used for both means of protection.
2. Monitoring Required. An external non-contact sensor or contact sensor may be used as a means of entrapment
protection. However, the sensor must be monitored once every cycle for (1) the correct connection to the operator and
(2) the correct operation of the sensor.
If the device is not present, not functioning, or is shorted, then the gate operator can only be operated by constant
pressure on the control device. Portable wireless controls will not function in this case.
3. Entrapment Risk Identification. As in the past, it’s up to the installer to examine the installation and determine
where a risk of entrapment or obstruction exists. Manufacturers are required to provide instructions for the placement
of external devices, but they give only examples of suggested entrapment protection in their installation manuals. If the
installer identifies a risk of entrapment or obstruction, at least two independent means of entrapment protection are
required.
4.Terminology Change. The terms “primary” and “secondary” have been removed in the description of entrapment
protection devices. This was done to emphasize that all entrapment protection devices are equally important.
Changes to UL 325 ED. 6th for Gate Operators

5. The End of Type E. Type E (audible alarm) devices can no longer be used for entrapment protection. This change
was made because the Type E device is really a warning device, not an entrapment-protection device. Also, all gate
operator classes are now required to have an audio alarm that sounds when two successive obstructions are
encountered via a contact-type system.
6. Access Control Location for Emergency Use. An exception has been added in the manufacturer’s instructional
requirements for the location of controls that operate the gate.
The instructional requirements state that these controls must be at least 6' away from any moving part of the gate. In the
new exception, “Emergency access controls only accessible by authorized personnel (e.g., fire, police, EMS) may be
placed at any location in the line-of-sight of the gate.”
7. Barrier-Arm Operator Exception. An exception has changed for barrier-arm gate operators requiring entrapment
protection. The previous exception stated that a barrier-arm operator did not require entrapment protection if the arm
did not move toward a rigid object closer than 2'. The distance has been reduced to 16" so it more closely aligns with the
industry-defined entrapment protection provisions in ASTM F2200.
8. Gate Operator Class II and Class III Definitions. The definitions for installation classes for gate operators were
modified. Class II now includes commercial locations accessible to the general public. Class III was refined to specify
industrial locations not accessible to the general public. These changes, while seemingly minor, may affect which gate
operator is suitable for a particular installation location.
UL 325 ED. 6th ENTRAPMENT PROTECTION REQUIREMENTS
This vehicular gate operator must be installed with at least two independent entrapment protection
means as specified in the table below.
International registered trademark n. 2.777.971
VERITICAL BARRIER NOTE:
Barrier gate operators (arm) that is not intended to move toward a rigid objact closer than 16 inches (406mm)

GATE WARNINGS
The first thing to check is that the gate is in good running order as follows:
A. The gate is rigid and straight and runs smoothly throughout its travel.
B. The length of each leaf must comply with max. length indicated on technical specifications of the model
C. The weight of each leaf must comply with max. weight indicated on technical specifications of the model
D. The hinges are hardly anchored and are able to support the torque of the operator; they do not have
irregular movements and/or any friction during the whole movement of the leaf.
PRECAUTIONS
SEA motors have been created for the automation of gates used by vehicles only. Be aware to avoid the
crossing of the gate path because it is very dangerous for pedestrians (fig. 4).
Install the warning signs, on each side of the gate and in avisible zone which informs the pedestrians
about the danger they run when passing or resting in the environment of the gate (fig. 5).
Important:
For a higher security, SEA advices to install infrared photocells.

BACK FIXING BRACKET MOUNTING
If the back fixing bracket has to be screwed and the «A» holes are used, the fixing bracket must be cut at a
distance of 2,65 inches from its end; if instead you use the other holes it is not necessary to do the cutting.
The support must be positioned so that the operator is in a perfect horizontal position (see Fig. 26 or 31)
CAUTION: before assembling the back and front fixing brackets lubricate with water repellent grease

can be welded or screwed
FRONT FIXING BRACKET MOUNTING
WARNING:
once the back bracket has been fixed,
immediately fix the front bracket,
always keeping the operator in a
horizontal position. Do not leave the
front of the operator detached
because it would fall down causing
damage

Fig. 23
Once the operator has been mounted on the back fixing
bracket, close the leaf of the gate and proceed as follows:
1) Release the operator keeping it always in a horizontal
position
2) Weld the front fixation bracket on the gate operating on
the the points indicated by the arrows (Fig. 23)
3) Place the operator on the front fixing bracket (SURF 350
- 450 as per Fig. 26 - 27) or insert the bracket into the
housing pin on the operator (SURF K as per Fig. 30 - 31)
and tighten the «A» screw to max 8.5 Nm (Fig. 27 or 30)
CAUTION: Lubricate the pin with grease before
installing the front fixing bracket on the operator
CAUTION: For the correct operation it is very important to position both the operator and its front
and back fixing brackets, in a perfectly horizontal way, using a level, as shown in Fig. 26 or 31
Furthermore the front fixing bracket MUST NOT TILT when it reaches the limit stop
(Fig. 28), otherwise serious damages can be caused to the electronic limit-switches
