also called a hen house flap gate or electronic door opener / closer ( Automatic Hen House Door Opener / Closer ) automatically opens and closes flap gates or other optionally available vertical sliding gates using a cable pull on the poultry or hen house, aviary, or small animal enclosure via a dimmer switch.
The drive unit in its own housing is connected to the control unit via a 7-core cable (not included in delivery). The motor with shaft and the light sensor are located in the housing of the drive unit.
Emergency stop or emergency opening function
Should an animal be under the slider during the closing process, the motor of the automatic chicken flap JT-HK is automatically stopped when it is put on. The emergency stop closing process is repeated 2 more times automatically. On the fourth closing attempt, the emergency stop function is deactivated. No animal has to free itself under the resting load of the flap, as is common with all other manufacturers.
Integrated lure light and lighting circuit Non-dimmable 230 V lighting as so-called lure light or as lighting can be connected and switched using an additional connection module. 12V LED lamps up to 12W can be connected directly to the device.
The lure light is automatically switched on the evening before the flap is closed. The light sensitivity for switching on the light can be adjusted in the menu on the display.
After the flap is closed, the lighting duration of the lure light can also be set in the menu to switch it off automatically.
The optional (additional) radio remote control FB-4T (with 4 keys) can be used to switch the lighting in the barn on and off manually.
Further options:
- Connection for external push-buttons available
- Connection for external remote indication available
- Connection for external light control available
If you assembly the HK2 indoors, your require an outdoor light sensor.
With our optionally available menu-driven electronic clock timer, the following functions can be set.
- HK2AE opens or closes only with the clock timer, the light sensor is idle
- HK2AE opens or closes only via light sensor, clock timer is idle
- HK2AE opens or closes with the clock timer and light sensor
- HK2AE opens or closes with the clock timer or light sensor
With the optionally available FB radio remote control, you can manually control the HK2AE.
Mounting:
Connection to plug-in power supply 230V / 12 V DC. The drive unit of the HK2AE should be mounted so that the internal cord is pulled straight out of the drive unit. Avoid diagonal pull! Control unit can be mounted anywhere. When open, the slider or the flap must be fastened by means of a connecting cord (not included in the scope of delivery) to the fastening point (aluminium nut), which is located on the underside of the housing of the drive unit when delivered. ( see installation )
The cord (cable pull) of the slider or the flap can be guided over cable or pulleys, therefore the mounting of the HK2AE is variable. (see mounting examples).
Scope of delivery without flap/slider, connecting cord and fixing material:
- automatic chicken flap HK2AE - control unit with menu-guided timer, incl. control for attraction light and lighting circuit Dimensions: width 120 mm, length 120 mm, height 55 mm + drive unit in its own housing with motor and wound-up pull cord with fastening nut,
- 230 V / 12 V DC plug-in power supply (approved for indoor use!), Ordernumber: 226
Not an assembly kit, no handicraft work, but a unit that is immediately ready for use!
Control up to 2 flaps with a single flap actuator.
The set of the multi-barn system includes the HK3 chicken flap with circuit for attracting light and 2 additional HKM drive. These open and close flaps either by setting from the HK3 or with remote buttons.
An NSM emergency power module in each of the HK3 and the HKM drive unit is only used to close the flaps in the event of a power failure.
The main system HK3 and the drive units HKM are connected via a special 4-wire cable or the cheaper variant, a network cable Cat 5 or higher (without plug), whereby 2 wires must always be used together. Cable not included, please order separately.
Real emergency stop or emergency opening function:
If there is an animal under the slide during the closing process, the motor is automatically stopped and the flap is opened again immediately. The closing process is automatically repeated several times. No animal has to free itself under the weight of the flap, as is usual with all other manufacturers!
This feature can be disabled in the settings.

Emergency power supply NSM (can also be ordered as an option):
You can select the variant with emergency power supply NSM above under the price.
The emergency power module is operated with a "12V 23AE" battery. Non-rechargeable !!
The battery serves as protection against failure in the event of a power loss. If the main supply fails, all devices close the flaps with the help of the batteries.
When the power supply is restored, HK3 and HKM restart and are ready for operation. All settings are retained.

Assembly instructions
An external outdoor light sensor is required for indoor installation or if the installation location is in the shade. For wall mounting, only use the 4 pre-drilled openings in the corners of the housing, each next to the cover attachment.
This way no moisture can get into the housing. Assembly instructions on anleitung-jt.de
Drive unit HKM:
The settings for opening and closing the flaps on the HKM drive units are made in the HK3.
With the external drive units HKM, an HK3 can control additional flaps. The HKM drive unit can only open and close flaps. Either by setting from the HK3 or with remote buttons.
In the event of a power failure, an emergency supply battery is only used to close the individual flaps.
The main system HK3 and the additional drive unit HKM are connected via a special 4-wire cable or the cheaper variant, a network cable Cat 5 or higher (without plug). This means that 2 wires must always be used together as one line.
Cables are not included, please order separately. The different conditions in your barn, such as the distances between the individual flaps, make it more cost-effective for you if the right lengths of cable are ordered right away.
Real emergency stop or Emergency opening function:
If there is an animal under the slide during the closing process, the motor is automatically stopped and the flap is opened again immediately.
