IMPORTANT SAFETY INSTRUCTIONS

SECONDARY MEANS OF PROTECTION AGAINST ENTRAPMENT

As specified by Underwriters Laboratories Inc. UL 325 (31.1.1), 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 SL-1000/2000 and GTO/PRO SL-1000B/2000B gate operators have provisions for the connection of Type B1 and B2 protection to be used as the secondary type of entrapment protection.

1.For gate operators utilizing a non-contact sensor (Type B1) in accordance with UL 325 (31.1.6):

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 (31.1.10):

A.One or more contact sensors shall be located at the leading edge, trailing edge, and post mounted edge, both inside and outside of a vehicular slide 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; 31.2.1)

The GTO/PRO SL-2000 and GTO/PRO SL-2000B 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., transmitter signal) and the gate returns to a fully open or fully closed position.

SL-1000, SL-2000 specifications

The GTO SL-2000 and SL-1000 are advanced gate operators designed for efficient and reliable automation of heavy-duty swing gates. These models are renowned for their robust construction and innovative technologies that enhance both performance and security.

The SL-2000 is particularly suited for large, dual-swing gates weighing up to 2,000 pounds, making it a perfect choice for commercial and industrial settings. In comparison, the SL-1000 is designed for lighter gates that weigh up to 1,000 pounds, suitable for residential and light commercial applications. Both models are engineered to provide smooth, quiet operation, which is vital for residential areas where noise reduction is essential.

One of the standout features of both the SL-2000 and SL-1000 is their advanced DC motor technology. This allows for variable speed operation, providing a slower, more controlled movement during the opening and closing cycles. Such functionality not only enhances safety but also minimizes wear and tear on the gate mechanism, ensuring longevity.

Both models are equipped with obstacle detection technology that halts the gate's movement if an obstruction is encountered. This safety feature helps prevent accidents and damage, a critical aspect in environments where individuals and vehicles are present.

In terms of installation, the GTO SL series is designed for ease of use, featuring a straightforward setup process with clear instructions and minimal tools required. Additionally, the SL-2000 and SL-1000 include a built-in rechargeable battery backup, ensuring that the gate operates even during power outages.

Security is a top priority with both gate operators. They incorporate rolling code technology in their remote controls, which changes the access code with each activation, significantly reducing the risk of unauthorized access. Furthermore, the SL series supports multiple remote controls, allowing for convenient access for users while maintaining security.

Durability is another hallmark of the GTO SL-2000 and SL-1000. Both operators are built with weather-resistant materials, ensuring they can withstand various environmental conditions. This resilience makes them a solid investment for long-term use.

In conclusion, the GTO SL-2000 and SL-1000 are state-of-the-art gate operators that combine cutting-edge technology with superior safety features, making them a reliable choice for enhancing the automation of swing gates in diverse applications.
