The dimensions of the PROTECO Strike-8 mechanism are convenient and in most cases, the available space is sufficient.

Choosing a sliding garage door mechanism

• The weight of the sliding garage door. The PROTECO Strike-8 mechanism is suitable for doors weighing up to 800kg.

The 800kg door weight covers most cases of doors since an average gate weighs 50-60 kg/m. Particular attention should be paid to ensuring that the door operates smoothly in manual mode. This means testing the door's movement without the mechanism or with the mechanism in manual operation mode. If the door does not operate smoothly, it should be repaired. Otherwise, it will cause problems for the mechanism and there will be malfunctions.

Sliding garage door - Checks before mechanism installation

The most important check that needs to be done even before ordering the mechanism is to check if the door operates smoothly by hand. We open and close the door at a steady speed, approximately the same as it would have with the mechanism. If at any point the movement presents difficulty, there is a jolt, etc., the door must be repaired before the mechanism is installed.

The checks that need to be carried out in detail are:

• If the rail is straight without curves, bumps, or rust. It must also be properly secured to the ground.
• The door's wheels must be in good condition. They should not show signs of deformation or rust. Their movement must be trouble-free.
• Shortly before the door's closed position, check for door sway. If it moves violently back and forth, intervention is required to repair the door. Possible repair points include the door's material (excessively flexible), the position where the rollers are installed (they have a large gap with the door), or the roller mounting point is too flexible.
• The door must enter smoothly into the receptacle at the closed position. It must "lock in" so that it cannot be easily lifted with a crowbar.
• The open and closed positions of the door must be defined by mechanical stops. Under no circumstances should the door leaf be free to pass beyond the closed or open position.

Typical layout of a sliding garage door with a mechanism

In the sketch above, we observe a typical layout of a sliding garage door with a mechanism. Obviously, the main element of the construction is the door leaf, which can be made of aluminum, metal, or wood. A basic prerequisite is that it must be sturdy and rigid enough to move, while only touching the wheels and rollers without excessive swaying.

The door must have mechanical stops to define the closed and open positions. The mechanical stops define the door's travel.

The rollers are placed at such a point that they are in contact with the door leaf throughout its entire travel (from the fully open to the fully closed position). Essentially, the rollers keep the door perpendicular to the ground. A basic prerequisite is that they should not hinder the door's movement.

The door rests on the wheels which allow it to move. The movement takes place on the rail, which is shaped to work perfectly with the wheels. The wheels must be in good condition, without signs of deformation or rust. The rail must be properly supported on the ground, be straight, and show no bumps or deformations.

The motor is also placed at a point where it is always in contact with the door. The movement is transmitted to the door from the motor's gear. The rack, which is a toothed rail, is mounted on the door. The rack is the point of contact between the door and the motor, and through it, the movement is transmitted.

Photocells are the most important accessory for a sliding garage door with a mechanism. They prevent accidents and protect both users and their vehicles. They are installed at the door's opening and prevent the sliding door from closing if there is an obstacle in its path.

Another accessory for a sliding garage door (not shown in the sketch) is the warning lamp. It is placed in a prominent position to warn passing vehicles and pedestrians that the garage door is in operation. This is a particularly useful device when the garage door is near a busy road or when visibility is not optimal.

Wiring of the PROTECO Strike-8 sliding garage door mechanism

The wiring of sliding mechanisms is a process that usually requires specialized personnel.

• The mechanism requires a 3x1.5mm² or 3x2.5mm² cable if the distance of the automation installation point is far from the control panel. (It is advisable for the mechanism to be on a separate fuse in the control panel).
• Wired photocells require a 4×0.6mm² cable for the receiver and a 2×0.6mm² cable for the transmitter. We usually place the receiver close to the mechanism. If it is impossible to route a cable across for the photocells, we can install reflector photocells, which only require wiring from one side.
• The warning lamp requires 1×1.0 mm² or 2×1.0 mm² wiring. (can be added separately from the set)
• The key switch or simple push button requires 2×0.6mm² wiring. (can be added separately from the set)

All cables must be protected from the weather (inside conduits).

Safety Photocells - Operation

Safety photocells are an economical but essential accessory for every type of garage door. They prevent accidents and do not require maintenance or any special care from the user.

Safety photocells consist of a transmitter and a receiver. The transmitter emits an infrared light beam, in the invisible spectrum, which is directed towards the receiver. When there is no obstacle interrupting the beam, the door operates normally. When, during the closing of the door, the beam is interrupted by an obstacle (vehicle, pedestrian, pet, etc.), the control panel instructs the mechanism to stop closing the door and begin the reverse movement (opening). If the beam is interrupted while the door is opening, it continues its course normally, while if it is open, it is not allowed to start closing.

If it is not possible to run cables for wired photocells, we can choose the solution of reflector photocells. These photocells require wiring only from one side of the door (the motor side), so they are easier to install. They are preferred in cases where the door and surrounding area have been completed without provision for wiring. They have a small surcharge compared to wired photocells but are a very good solution when wiring cannot be run. In the set, you can add either wired photocells or reflector photocells.

Wired photocells NOLOGO IR5001P / Zoom-Z2E

The NOLOGO IR5001P / Zoom-Z2E photocells are a reliable choice of wired photocells consisting of a transmitter and a receiver with a range of 20m. As wired photocells, they require wiring on both sides of the opening.

Technical characteristics of NOLOGO IR5001P / Zoom-Z2E photocells:

• Operating voltage: 12 or 24 V DC, 12 or 24 V AC
• Maximum operating distance: 20m
• Maximum contact current: 0.5 A at 48 V AC/DC
• Transmitter operating current: 25 mA
• Receiver operating current: 35 mA
• Interference rejection circuit from other light sources
• Auto focus

They are usually installed at a height of 50cm from the ground. They are simple to install and can prevent major damage and accidents. Their operation is trouble-free as they do not require maintenance, are not affected by weather conditions, and do not require any action from the user during their use.

Safety photocells with reflector Witt Sensoric RP25

The biggest advantage of photocells with a reflector is that they only require wiring from one side where the transceiver is installed. The reflector is installed opposite. The reflector has dimensions of 10x10cm, while the dimensions of the transceiver are:

Characteristics of Witt Sensoric RP25 safety photocells with reflector:

• Convenient size and shape for both transceiver and reflector.
• Do not require batteries like other competing wireless photocells.
• Reliable operation even in harsh weather conditions (suitable for outdoor use).
• 15m range covering most sliding doors.
• Not interfered with by sunlight or other light sources as they operate with a polarized light filter. This means they can detect even reflective objects between the transceiver and the reflector, making them less likely to be fooled by a car's polished surface.
