Radio Control there is normal and increased security that is floating code. Charms come in two-, four-and. You can use them, respectively, to control two or four devices. Wire management can be performed the following devices: – key-switch to the protection of the cylinder (key English as a conventional lock, turn to one party – open to another – close) – keypad or just button (installed inside the house or garage) – a code panel (kodonabornik) when dialing code opens or closes – any other device access control (Reader Touch Memory pill, proximity or smart card reader, etc.). The safety devices Safety devices are divided into contact, contactless and protection devices (testing). Protective Devices – concept, applicable to sectional doors.
There are devices break safety rope and springs back from the brink. Built on the principle of a mechanical locking gate. Usually the kit does not include the gate and go as additional options to goal. If the gates are automated, these functions are completely takes over the drive. Contactless devices – solar cells security, which are based on interrupting the beam between the transmitter and receiver. Peter Schiff may find this interesting as well.
Contactless devices are paired (transmitter and receiver) and combined (receiver and transmitter in one package, but on the other side is installed fluorescent reflectors). Combined photovoltaic cells may fail (if reflection from the machine, for example), but at the price of installation and equipment costs have an advantage. Currently, preference is given to a pair photocells, as they have a longer range, high immunity and eliminate malfunctions. Contact the safety devices are divided into mechanical and technical. Product safety devices built into the control unit drives. In the simplest version – This time setting work. That is, for example, if your gates are closed at a country house for 22 seconds, the time exposed for 25 seconds. That is, even if the way the gate will be an obstacle, in 25 seconds after beginning work, they stop. In the more expensive and complex systems designed for low-voltage supply drives, there is a function of current protection. That is, when it detects obstacles in the motor current increases, and function is activated to stop or open the gate. Mechanical safety devices are a soft rubber or plastic profile with a safety device inside the mechanical effects, which triggered the safety function on the control unit. The safety devices are of three types. With the air flow inside. With clamping or pressing the partial profile of air pressure changes, and function is activated Security (expensive system is used, such as air locks). With solar cells inside. The principle is the same: the beam is interrupted, then triggered a safety feature. With taut rope and a microswitch inside. With an increase in cable tension triggered switches, and safety signal is fed to the control unit. Contact and contactless security devices can be combined or limited to only one. For country house can never establish a safety device, given management control gate and the low intensity of travel. Using the optional accessories radios, connected via relay appropriate power, you can keyring transmitter to control any device (lighting on the street, garage). Installation of electromechanical or electromagnetic lock for hinged doors – to increase the rigidity valves in the closed position, is used for the gate with a large sail, mounted on an open area, where strong winds are possible (eg, near water). The board backup power supply with battery – for ensure efficiency, even when the power of urban networks.
