Chicken Houses | Chicken Coops | Automatic Door Opener

An automatic door opener for opening and closing chicken houses at each end of the day. Fitting inside the house but also supplied with an external light sensor.

This automatic control device can be used wherever a vertical sliding gate is to be opened and closed in response to light conditions at dawn and dusk, for instance, on a chicken house, etc.

The sensitivity of the system is adjustable. Using our timers, it is possible to open and to close the sliding gate according to the time setting or to open it according to the time setting and to close it in response to the light conditions at dusk

The VSB unit is suitable for outside installation, is weatherproof, can readily be exposed to sunlight and is insensitive to lightning stroke.

Mounting is very easy: Open the sliding gate, fasten it on the VSB unit and insert the batteries.

The lower stop will be automatically "chosen" by the sliding gate, i.e., when the latter reaches the lower position.
The maximum stroke length of 50 cm can be increased, upon request. The system makes it also possible to operate several sliding gates via idlers.

Power supply: 4 type AA (LR6) alkaline batteries.

These door openers are great devices but keep a regular check that their operation is not blocked by a jamed door, ensuring the door sliding channels are kept clean at all times.

    Compact geared motor with steel gears ensuring extremely long life.
    Battery life now 3 to 4 years with an HS sliding gate or 2 years with a 1.5-kg sliding
    gate featuring a 50-cm lift.
    Dorkeeper operates considerably more quietly now.
    Thanks to 40-kg breaking strength, the rope can hardly break any more.
    Electronic shutdown of motor within one second when the sliding gate is blocked.
    Once the blockage ist removed, the sliding gate will be opened within three minutes.
    The strain on the batteries is virtually negligible.
    Tensile force: 200 g to to 3 kg, with idler UR on the sliding gate (pulley) 6 kg.

Functionality test. Fully darken the Doorkeeper (which is hardly possible in sunlight) or close it by actuating the timer or bridge pins 3 and 4 of the Doorkeeper by means of a screwdriver so that the sliding gate is lowered until it reaches the bottom and switches off. After about 10 seconds the sliding gate is opened. Do not move or hold any part of the doorkeeper during this test.

Varying the Light sensitivity. The adjuster (above the pins 5 and 6 , "slot marked with arrow') has been set in such a way that the sliding gate is closed relatively early. If it is still too bright for closing at this time, turn the controller clockwise. Check the adjustment later and readjust the controller anti clockwise, if necessary. Shield your Doorkeeper from artificial lighting sources!

Please take time to set up the unit correctly.

Vertical sliding gate, approx. 22cm (W) x 33cm (H) (9"x13"), complete with sliding rail Is also an option
