the gate to warn pedestrians of the dangers of motorized gate systems.

» INSTALLATION CLASSIFICATIONS
RESIDENTIAL
The chart above illustrates the entrapment protection requirements for
each of the three classes.
In order to complete a proper installation you must satisfy the entrapment
protection chart shown above. That means that the installation must have
one primary means of entrapment protection. A secondary means of
entrapment protection is
highly recommended
. Both
primary and secondary entrapment protection methods must be designed,
arranged or configured to protect against entrapments in both the open
and close directions of gate travel.
For Example:
For a slide gate system that is installed on a single-
family residence you must provide the following: As your primary type of
entrapment protection you must provide Type A inherent (built into the
operator) entrapment sensing and we highly recommend at least one of
the following as your secondary entrapment protection: Non-contact
sensors such as photoelectric eyes (type B), Contact sensors such as gate
edges (type C).

SAFETY ACCESSORY SELECTION
Merlin gate operators will accept external entrapment protection devices to protect
people from motorized gate systems. Below are the types of entrapment protection
systems for use on this operator.
ENTRAPMENT PROTECTION TYPES
Type A: Inherent obstruction sensing system, self-contained within the operator.
This system must sense and initiate the reverse of the gate within two
seconds of contact with a solid object
(included)
.
Type B: Connections provided for a non-contact device, such as a photoelectric
eye can be used as a secondary protection
(included)
.
Type C: Connections provided for a contact sensor. A contact device such as a
gate edge can be used for secondary protection (optional).
