GTO RB923 rev Secondary Means of Protection Against Entrapment, Entrapment Alarm UL 325 30A.1.1A

IMPORTANT SAFETY INSTRUCTIONS

Secondary Means of Protection Against Entrapment

As specified by Underwriters Laboratories Inc. UL 325 (30A.1.1), automatic gate operators shall have provisions for, or be supplied with, at least one independent primary and one independent secondary means to protect against entrapment. GTO gate operators utilize Type A, an inherent entrapment sensing system, as the primary type of entrapment protection. The GTO/PRO 2000 series gate operators have provisions for the connection of Type B1 and B2 protection to be used as a secondary type of entrapment protection, if desired.

1.For gate operators utilizing a non-contact sensor (Type B1) in accordance with UL 325 (51.8.4 [h]):

A.Refer to the sensor manufacturer’s instructions on the placement of non-contact sensors for each type of application.

B.Care shall be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving.

C.One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such as the perimeter reachable by a moving gate or barrier.

2.For gate operators utilizing a contact sensor (Type B2) in accordance with UL 325 (51.8.4 [i]):

A.One or more contact sensors shall be located at the leading edge, bottom edge, and post mounted both inside and outside of a vehicular swing gate system.

B.A hard wired contact sensor shall be located and its wiring arranged so that the communication between the sensor and the gate operator is not subjected to mechanical damage.

C.A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate operator for entrapment protection functions shall be located where the transmission of the signals are not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall function under the intended end-use conditions.

ENTRAPMENT ALARM (UL 325; 30A.1.1A)

The GTO/PRO 2000 series gate operators are designed to stop and reverse for 2 seconds when the gate comes in contact with an obstruction or when an object activates the non-contact sensors. Additionally, these operators are equipped with an audio entrapment alarm which will function if the unit obstructs twice while opening or closing. This alarm will sound for a period of 5 minutes or until the operator receives an intended signal (e.g., a transmitter signal) and the gate returns to a fully open or fully closed position.
