i) For gate operators utiliing a non-contact sensor:
1 See instructions on the placement of non-contact sensors for each Type of application
2 Care shall e exercised to reduce the risk of nuisance tripping such as when a vehicle trips the sensor while the
gate is still moving
3 ne or more non-contact sensors shall e located where the risk of entrapment or ostruction exists such as the
perimeter reachale y a moving gate or arrier
) For a gate operator utiliing a contact sensor:
1 ne or more contact sensors shall e located where the risk of entrapment or ostruction exists such as at the
leading edge trailing edge and postmounted oth inside and outside of a vehicular horizontal slide gate.
2 ne or more contact sensors shall e located at the ottom edge of a vehicular vertical lift gate.
3 ne or more contact sensors shall e located at the pinch point of a vehicular vertical pivot gate.
4 A hardwired contact sensor shall e located and its wiring arranged so that the communication etween the
sensor and the gate operator is not suected to mechanical damage.
5 A wireless contact sensor such as one that transmits radio freuency F signals to the gate operator for
entrapment protection functions shall e located where the transmission of the signals are not ostructed or
impeded y uilding structures natural landscaping or similar ostruction. A wireless contact sensor shall
function under the intended end-use conditions.
6 ne or more contact sensors shall e located on the inside and outside leading edge of a swing gate. Additionally
if the ottom edge of a swing gate is greater than 6 inches 152 mm aove the ground at any point in its arc of
travel one or more contact sensors shall e located on the ottom edge.
7 ne or more contact sensors shall e located at the ottom edge of a vertical arrier arm.
nstruction regarding intended operation of the gate operator shall e provided as part of the user instructions or as a
separate document. The following instructions or the euivalent shall e provided
NOTICE
As for misunderstandings that may arise refer to your area distriutor or call our help desk. These instructions are part
of the device and must e kept in a well known place. The installer shall follow the provided instructions thoroughly.
SEA products must only e used to automate doors gates and wings. Any initiative taken without SEA USA nc. explicit
authorization will preserve the manufacturer from whatsoever responsiility. The installer shall provide warning notices
on not assessale further risks. SEA USA nc. in its relentless aim to improve the products is allowed to make
whatsoever adustment without giving notice. This doesnt olige SEA to up-grade the past production. SEA USA nc.
can not e deemed responsile for any damage or accident caused y product reaking eing damages or accidents
due to a failure to comply with the instructions herein. The guarantee will e void and the manufacturer responsiility
will e nullified if SEA USA nc. original spare parts are not eing used. The electrical installation shall e carried out y
a professional technician who will release documentation as reuested y the laws in force. Packaging materials such
as plastic ags foam polystyrene nails etc must e kept out of childrens reach as dangers may arise.
To respect the norms in force it is recommended to use the ENCODER SYSTEM together with the electronic
control units
Starting on an. 12 2016 new UL 325 changes take effect ringing a series of new mandates for the gate operator
industry. eres a uick guide to the key modifications.
1. Entrapment-Protection Deices. ate operators are reuired to have a minimum of two independent means of
entrapment protection where the risk of entrapment or ostruction exists. A manufacturer can use two inherent-type
systems two external-type systems or an inherent and an external system to meet the reuirement. owever the
same type of device cannot e used for oth means of protection.
2. Monitoring Reuired. An external non-contact sensor or contact sensor may e used as a means of entrapment
protection. owever the sensor must e monitored once every cycle for 1 the correct connection to the operator and
2 the correct operation of the sensor.
f the device is not present not functioning or is shorted then the gate operator can only e operated y constant
pressure on the control device. Portale wireless controls will not function in this case.
3. Entrapment Ris Identification. As in the past its up to the installer to examine the installation and determine
where a risk of entrapment or ostruction exists. Manufacturers are reuired to provide instructions for the placement
of external devices ut they give only examples of suggested entrapment protection in their installation manuals. f the
installer identifies a risk of entrapment or ostruction at least two independent means of entrapment protection are
reuired.
4.Terminolog Change. The terms primary and secondary have een removed in the description of entrapment
protection devices. This was done to emphasize that all entrapment protection devices are eually important.
