NOTES:
1. The same type of device shall not be used for both entrapment protection means. Use of a single device to cover both
the opening and closing directions is in accordance with the requirement; however, a single device is not required to
cover both directions. Tice installer is required to install entrapment protection devices in each entrapment zone
2. FOR VERITICAL BARRIERS ONLY: Barrier gate operators (arm) that is not intended to move toward a rigid objact
closer than 16 inches (406 mm) are not required to be provided with a means of entrapment protection
* B1 and B2 means of entrapment protection MUST be MONITORED
Changes to UL 325 ED. 6th for Gate Operators
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:
a. the correct connection to the operator
b. 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.
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.

The first thing to check is that the gate is in good running order:
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.
- SEA operators have been designed for the automation of gates for vehicles use only
Be aware to avoid the crossing of the gate path because it is very dangerous for pedestrians
- Install the warning signs on each side of the gate and in avisible zone to inform the pedestrians
about the danger they run when passing or resting in the environment of the gate
- For more safety SEA advises to install infrared photocells
