The basic VSD solution. Control via twilight (timed with optional accessories) and manually, power supply by solar cell and NiMH rechargeable batteries. Electronic Doorkeeper VSD - solar version > a solar cell is built in + NiMH rechargeable batteries inserted instead of the standard alkaline batteries. Reliable, safe operation, regardless of weather and season – even if the sun takes a break. The device operates even more independently of the installation location. Installation in sunlight or good daylight illumination required. Alternatively: connection of external solar cell "Solar2b" possible. Open and close when it gets light or dark. Opens the chicken flap automatically when it gets light. Closes the chicken flap automatically when it gets dark. The light sensor is built into the device. No extra light sensor required if the device is mounted outside on the coop. If the Doorkeeper is mounted inside the coop, please order a sensor extension, the outdoor light sensor (ASb), in the appropriate length as well. Open and close the chicken flap manually as well. The magnet is briefly held against a control panel on the device, causing it to open or close. Is the device installed inside…? So you cannot reach the control panel for manual operation? Order the extension (ext.SA) at the same time. Place the control panel for the magnet in a location that is easy for you to reach. Power supply by solar Operation is via integrated rechargeable batteries, which are charged via an integrated solar cell. The device is intended for outdoor installation so that the solar cell is correspondingly illuminated. Alternatively, an external solar cell can be connected, which then takes over the function of the internal one (Solar2b). This enables a high degree of independence from power sockets and is ideal, for example, for mobile chicken coops. The device indicates via an LED when the rechargeable batteries are too deeply discharged. Further information Extensions are available for some convenient functions. External light sensor (various lengths) can be connected (optionally available) – for mounting the device inside the coop Extension of manual operation (various lengths) – this makes convenient manual operation possible even when the device is mounted in the coop! Adding a timer function by connecting an external timer switch (BS-D / BS2) possible (optional) optimised mechanics – resulting in a durable cord slider weight of up to 3kg possible If you need a Doorkeeper with which you want to open a pasture gate, then please take a look at the pasture gate openers BZ1, BZ3 (click on designation). These are the perfect combination for this application. The VSD is only suitable in combination with the external BS-D timer for horse applications. As a company, we have been manufacturing devices of this type for over 40 years. We place great value on durable products and strong customer service at a fair price. The Electronic Doorkeeper automatically opens and closes vertical sliders on chicken houses. This happens either via the light sensor and / or a timer switch. In addition, manual control is possible, independently of the twilight and timer control. The light sensor is basically built into every device. So nothing else is required if the device is mounted outside on the coop. If it is mounted inside the henhouse, a sensor extension is required. If the flap closes and there is an animal underneath, the device stops and only continues closing once the animal has moved away again. The device has overload protection. It reacts in a cord-protecting manner and repeatedly attempts to open. The slider could, for example, be frozen up. The housings of all devices in the VS series are extremely robust. The electronics are protected on the underside of the board in SMD technology with a special coating against aggressive gases, moisture and dirt. The VSD can be mounted outside if it is placed with slight protection, and it does not open during thunderstorms (lightning). Manual operation: With this device it is possible to close manually during the day. To do this, a magnet is held against a certain point on the housing. The slider is closed and remains closed for that day. It is opened again automatically the next morning. There is also the possibility to open the Doorkeeper again on the same day. To do this, the magnet is held against the control surface again. LED display: The device indicates to you at intervals of several seconds via multicolour LED when: a) the batteries are empty or replacement should be considered b) the device must be in closed mode according to the limit switch position c) further general faults (for example cord wound the wrong way) The LED indications are output for a limited time (for example flap closed for approximately up to 1h after the closing process) in order to keep the battery load as low as possible. Possible accessories for the device: Extension of the built-in light sensor ASb: With the help of a light sensor extension, you can also mount the device and the slider in the henhouse. The Doorkeeper then gets the correct light information from the sensor extension, which can be mounted very easily e.g. in the wooden wall of the henhouse, or attached in another place, slightly protected. Cable lengths up to 6m are available. External manual operation, ext.SA:Would you like to open or close manually conveniently? An automatic chicken flap is often not conveniently accessible in order to trigger the function there. With the extension of the manual operation you have a solution to the problem. Place the control panel for the magnet in a place that you can easily reach in order to hold the magnet there. A great relief. Cable lengths are available up to 6m. Extension of the internal LED, ext.LED: The device outputs status information from time to time. For example, it informs you when the batteries need to be replaced, when the flap is in closed mode or if there should generally be an error. You do not see this information if the Doorkeeper is installed inside. With the LED extension you get around the problem by mounting the ext.LED in a more visible place. In addition, the external LED is also brighter than the internal one. External timer switch (accessory): If you would also like to control the flap by time, or exclusively by time, you need a separately available external timer switch for the VSD. We have these timers as battery-operated and mains-powered versions. If you intend to operate the Doorkeeper by means of a 12V power supply unit at the socket, you should use the mains-powered timer switch. We have digital and analogue timers in our range. The digital ones are available as a battery-operated version (BS-D) and a mains-powered version (ZS-D). Our analogue timer is available as a battery version. How it works: The timers define a period during which it is definitely closed. This is generally, for example, from 10 pm until 8 am in the morning. Outside this time, the light sensor determines whether it is opened or closed. This results in this combination being closed in the evening by twilight, but by 10 pm at the latest. In the morning it opens from 8 am, provided it is light. If not, it opens as soon as it is light enough to do so. Furthermore, it is possible to control the Doorkeeper exclusively by time, i.e. without influence of the light sensor. It is not possible to operate a VSD and an older VSB together on one timer switch. However, it is possible to operate several VSDs on one timer switch and several VSBs on another timer switch. Notes on installation to avoid misunderstandings or problems:You receive the device in the open position, i.e. with the cord wound up. A loop protrudes from the device. First you mount the rails, then insert the slider and pull it into the open position. Above that you mount the device so that you can connect the loop of the device to the slider. This defines the upper stop… very simple. If the device does not fit directly above the open slider, mount the device next to it, or elsewhere. You can now connect the loop of the device and the open slider with an extension cord, which you then guide over pulleys if necessary.

Function: The quartz-accurate and dustproof BS-D timer is an optional accessory for the battery-powered Electronic Doorkeeper (VSBb and VSD), Electronic Doorkeeper and flap actuator. It is used when the electronic Doorkeeper – and thus the slide gate – is to be controlled on a timed basis (for example, opening and closing at set times, or opening at a set time and closing at dusk). The BS-D timer with batteries can control up to three VSBs simultaneously (use of a terminal block and separate cables (to be provided by the customer) – please enquire in advance). The BS-D contains 2 AA batteries (Mignon), which will last for approximately six years. A necessary battery change is indicated in good time. All settings are retained for approximately two minutes whilst the batteries are being changed. If dusk falls at around 10:30 p.m. in June, for example, you can use the BS-D timer to have the shutter close automatically at 10:00 p.m. (factory setting). Automatic closing is therefore also possible before dusk. If, a few weeks later, it gets dark before this time, automatic closing will resume at dusk. The timer sets a time period during which the gate is always closed. Outside this period, the gate will close or open depending on the light conditions. If you do not want this to happen, the twilight sensor in the Doorkeeper must be deactivated. This is done using a jumper cable supplied with the timer. This ensures that the gate remains open at all times, unless the timer closes it.

Description: Medium-sized, widened sliding gate for securing animal pens such as duck coops (accessory for VSB, VSC, VSD and Doorkeeper VSE).The slide plate is wider than on the standard mHS. This gives the animals a little more space when leaving the poultry house. The number of slides is limited. Assembly note 1: The rails have an H-shaped profile. The lower drill holes are on the inside. The upper drill holes are on the outside. This prevents the sliding panel from jamming when opened. Installing the sliding panel may create a small gap. The best way to close this is to fit a piece of wooden slat on the floor in front of the sliding panel. This also provides good protection against martens or foxes. Installation note 2: The sliding panel runs approximately 1 cm within each rail. Therefore, if the rails are to be fitted flush with the opening, the opening must not exceed 40 cm in width. However, we recommend waiting until you can hold the sliding panel and rails in place so that you can cut the opening to size accordingly. A marten-proof rail is currently unavailable.
