Linking to Home Automation Systems:

There are several hard-wired methods used to connect blind motors to Home Automation Systems (HAS) or Building Management Systems (BMS). The most common method is through an electronic  controller or directly connecting to a HAS/BMS providing that the system has an Interlocking Feature and Individual Outputs for every motor. Interlocking means that when an up or down direction is activated the opposite direction cannot be physically switched or is disabled. The interlocking and Individual Outputs features are critical to this type of installation. If they cannot be achieved do not use this method of installation.

Available Options Include:

The CD4 Controller – which is a single motor controller (relay) that requires its own 240 V power supply, with an output voltage of 240V A/C (latched). The switching consists of multiple Dry contact impulse switching (impulse contact closure of one second minimum). Contact closure between Common and Up or Down will activate the motor in the appropriate direction and a contact closure between all three contacts Common, Up and Down will create a Stop Command.
The CD4 can also be used to control a group of motors through a  Group Motor Controller (3GMC or 4GMC). CD4’S may be connected together for multiple switching applications via Busline. This allows for an Individual control from a dedicated switch and for the control of all CD4’S from a master switch / controller.

 

Moduline ( Master ) Controllers – require their own 240 V power supply and must be used in every Moduline configuration. The Master Controller provides the power for the control circuitry to an individual controller (1 Master Controller is capable of Controlling 16 individual units). Both these units utilise Dry contact impulse switching (impulse contact closure of one second minimum) and can be controlled by the HAS/BMS in this way. Contact closure between Common and Up or Down will activate the motor in the appropriate direction and a contact closure between all three contacts Common, Up and Down will create a Stop Command.

 

 

 

The ILT Motor – requires its own 240 Volt power supply and has a built-in Flat 4 Point control cable (male phone plug RJ9) that can be easily connected to most HAS/BMS when used in conjunction with a Phone Plug Connector. The HAS/BMS must be capable of Dry contact impulse switching (impulse contact closure of one second minimum). Contact closure between Common and Up or Down will activate the motor in the appropriate direction and a contact closure between all three contacts Common, Up and Down will create a Stop Command.

Direct 240V Switching – should only ever be used in conjunction with Standard Switch motors. This method of connection is only used when the HAS/BMS is going to be the only source of control, has the ability to interlock between the up and down commands and provide Individual Outputs for every motor. These features are critical to this type of installation and if they cannot be achieved do not use this method of installation. Interlocking means that when an up or down direction is activated the opposite direction cannot be physically switched or is disabled. The HAS/BMS must switch 240V to the up or down directional wires to drive the motor and 0V to stop the motor. In a scenario with multiple motors each motor will require it’s own individual connection to the HAS/BMS.
IMPORTANT NOTE: If both up and down are activated at the same time this will cause unrepairable permanent damage to the motor.

RTS CONFIGURATIONS
There is only one method of interfacing RTS configurations with HAS/BMS and that by using a  Busline Transmitter. This Transmitter requires its own 240V power supply and has Dry contact impulse switching inputs that connect to the HAS/BMS (impulse contact closure of 5 to 10 seconds minimum). Once powered the Busline Transmitter can be programmed to internal or external  RTS Receivers that control the motor. For individual control use one Busline Transmitter per RTS Receiver and for group control use one Busline Transmitter per group.

IMPORTANT NOTE: If two or more Busline Transmitters are activated at the same time the sent command will not work (the radio signals cancel each other out)
