IMPORTANT SAFETY INFORMATION

Important Safety Instructions

WARNING: TO REDUCE THE RISK OF SEVERE INJURY OR DEATH:

•READ AND FOLLOW ALL INSTRUCTIONS.

•Never let children operate or play with the gate controls. Keep remote controls away from children.

•Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF A MOVING GATE.

•Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or when an object activates a non-contact sensor. If necessary, adjust the force or the limit of travel and then retest the gate operator. Failure to properly adjust and retest the gate operator can increase the risk of injury or death.

•Use the manual release mechanism only when the gate is not moving.

•KEEP GATE PROPERLY MAINTAINED. Have a qualified service person make repairs to gate hardware.

•The entrance is for vehicles only. Pedestrians must use a separate entrance.

•SAVE THESE INSTRUCTIONS.

Important Installation Instructions

1.Install the gate operator only when the following conditions have been met:

•The operator is appropriate for the type and usage class of the gate.

•All openings of a horizontal slide gate have been guarded or screened from the bottom of the gate to a minimum of 4 feet (1.25 m) above the ground to prevent a 2.25 inch (55 mm) diameter sphere from passing through openings anywhere in the gate or

through that portion of the adjacent fence that the gate covers when in the open position.

•All exposed pinch points are eliminated or guarded.

•Guarding is supplied for exposed rollers.

2.The operator is intended for installation on gates used by vehicles only. Pedestrians must be provided with a separate access opening.

3.To reduce the risk of entrapment when opening and closing, the gate must be installed in a location that allows adequate clearance between the gate and adjacent structures. Swinging gates shall not open outward into public access areas.

4.Before installing the gate operator, ensure that the gate has been properly installed and that it swings freely in both directions. Do not over-tighten the operator clutch or pressure relief valve to compensate for a damaged gate.

5.User controls must be installed at least 6 feet (1.83 m) away from any moving part of the gate and located where the user is prevented from reaching over, under, around or through the gate to operate the controls. Controls located outdoors or those that are easily accessible shall have security features to prevent unauthorized use.

6.The Stop and/or Reset buttons must be located within line-of-sight of the gate. Activation of the reset control shall not cause the operator to start.

7.All warning signs and placards must be installed and easily seen within visible proximity of the gate. A minimum of one warning sign shall be installed on each side of the gate.

8.For gate operators that utilize a non-contact sensor (photo beam or the like):

•See instructions on the placement of non-contact sensors for each type of application.

•Exercise care to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving.

•Locate one or more non-contact sensors where the risk of entrapment or obstruction exists, such as at the reachable perimeter of a moving gate or barrier.

•Use only FAAC “Photobeam” photoelectric eyes to comply with UL325.

FAAC MODEL 844 Slide Gate Operator	4

Important Installation Instructions (continued)

9.For gate operators that utilize a contact sensor (edge sensor or similar):

•Locate one or more contact sensors where the risk of entrapment or obstruction exists, such as at the leading edge, trailing edge, and post mounted both inside and outside of a vehicular horizontal slide gate

•Locate one or more contact sensors at the bottom edge of a vehicular vertical lift gate.

•Locate one or more contact sensors at the bottom edge of a vertical barrier (arm).

•Locate one or more contact sensors at the pinch point of a vehicular vertical pivot gate.

•Locate hard-wired contact sensors and wiring so that communication between sensor and gate operator is not subjected to mechanical damage.

•Locate wireless contact sensors, such as those that transmit radio frequency (RF) signals, where the transmission of signals are not obstructed or impeded by building structures, natural landscaping

or similar hindrances. Wireless contact sensors shall function under their intended end-use conditions.

•Use only FAAC MSE MO, CN60 or M60 edge sensors.

MODEL 844 OPERATOR

1.DESCRIPTION & SPECIFICATIONS

These instructions apply to the following models:

844 ER Z16 CR, 844 R, 844 R CAT, 844 R RF

The FAAC Model 844 automated system for sliding gates is an electro-mechanical operator transmitting motion to the sliding leaf via a rack or chain pinion appropriately coupled to the gate.

The non-reversing system ensures the gate is mechanically locked when the motor is not operating and, therefore, no lock needs to be installed.

The gearmotor is equipped with a mechanical clutch which, combined with an electronic device, offers the necessary adjustable anti-crushing safety and guarantees stopping or reversing the gate movement. A handy manual release makes it possible to move the gate in the event of a power cut or malfunction. The control board, if supplied with the gearmotor, it is placed inside the operator.

The 844 automated system was designed and manufactured to control access of vehicles. Avoid any other use whatever.

1.1.MAXIMUM USE CURVE

The curve makes it possible to establish maximum work time (T) according to use frequency (F). The 844 gearmotor can operate non-stop at 70% use frequency.

To ensure efficient operation, operate in the work range below the curve.

Important: The curve is obtained at a temperature of 75°F. Exposure to direct sunlight can reduce use frequency down to 20%.

Calculating Use Frequency

The percentage of effective work time (opening + closing) compared to total time of cycle (opening + closing + pause times).

		Calculation Formula
	%F =	Ta + Tc	X 100
		Ta + Tc + Tp + Ti

Where: Ta = opening time Tc = closing time Tp = pause time

Ti = time of interval (between 2 complete cycles)

4.INSTALLING THE SYSTEM

4.1.PRELIMINARY CHECKS

To ensure safety and an efficiently operating automated system, make sure the following conditions are observed:

•The gate structure must be suitable for automation. For example, wheel diameter must be in proportion to the weight of the gate to be automated, an upper guide must be provided, mechanical stop limits to prevent the gate derailing must be installed.

•The soil must permit sufficient stability for the concrete pad.

•There must be no pipes or electric cables in the pad excavation area.

•If the operator is exposed to passing vehicles, install, if possible, adequate means of protection against accidental impact.

•Check if an efficient grounding is available for connection to the gearmotor.

4.2.FOUNDATION PLATE INSTALLATION

1.Assemble the foundation plate as shown in Fig 4. The foundation plate must be located as shown in Fig 5 (right closing) or Fig 6 (left closing) to ensure that the rack and pinion mesh correctly.

2.Prepare a concrete pad as shown in Fig.7, following the suggested dimensions. It’s recommended to have the pad a minimum of 4” above level grade to avoid any flooding of the operator. The underground depth of the concrete pad is determined by the soil condition and the local building codes. Make sure the concrete pad is leveled.

3.Provide one or more conduit pathways for all power and accessory connections. Extend the conduit about of 1/2” above the level of the concrete pad.

4.After the concrete is poured in the forms and before it has a chance to set, insert the foundation plate into the cement and position it flush with the top of the concrete and aligned with the top of the lower gate frame. Use the dimensions shown in Figs 5 or 6 to align your foundation plate. Allow the concrete to set for a minimum of two days before installing the operator.

5.Route the wires in the conduits. To facilitate the connections allow for about 15” of extra length of cables out of the conduit. Separate the high and low voltage wires in different conduits.
