Home Management Systems How do I link to my blind controls ?
Requirements for linking window blind controls
It is not possible to link our Centralis system into a home management system without an interface box.
The signal lines from the home automation system are connected to the bus line of our interface box, a volt free contact is required. The stop is achieved by a simultaneous impulse signal across both open and closed* contacts. The stop facility is essential. Reversing the signal lines is not an option a separate common is necessary i.e. you cannot use the closed as the common on the open signal.
Because switching is instant a millisecond time delay should be allowed to avoid the motor receiving simultaneous up and down signals that could override the limits.
As the receiver can be programmed to receive instructions from more than one transmitter the blinds can be operated from the home automation console or there is the option to use a separate hand held or wall mounted transmitter.
The blind motor is located in the motor tube or blind headrail and a connector plug or junction box is required adjacent to the blind so that it can easily be disconnected from the power.
The receiver box (Centralis) is normally located near to the motor to reduce the cable runs from the motor.
As the system is radio remote the transmitter does not have to be in line of sight (as with infra red) and will pass through walls although the distance should not be more than 200 metres in open space reducing to 20 metres through 2 concrete walls.
An interface box is required for every motor, or if the blinds are only to be operated as a group, for every group of blinds. Where they are grouped a relay will be needed between the blind motors and our control box. Where group and individual control is required an interface box will be needed for each motor and also one for each group.
• open and closed for non-retractable blinds or louvers would be up and down for Venetian or roller blinds.
