Goodwood Electronics
Those installations where your customer just wants an exhaust fan added to the toilet but doesn't want it to be switched on with the light, should be very straight forward. But, of course the construction is solid brick and the switch is on an internal wall. The room of course, has just been tiled so the customer doesn't want you to chase a new cable into the wall.
Goodwood Electronics' provides a simple device that allows for two independent devices to be switched over a single switchwire. Now, this isn't a wireless solution nor is it a complicated electronic product that needs to be configured with an app on a smartphone or a computer. It's a very simple product that sends two signals from two switches in the wall to two relays that are housed in a junction box in the roofspace. This technology is tried and tested and is being used for many applications such as...
Providing auto/manual/off switching for sensor lights over a single switchwire
Providing open/close/stop switching for motorised blinds over a single switchwire
Providing limited 2-way switching solutions where no strappers are available.
Providing a functional switch solution for remote control ceiling fans where the manufacturer of the fan demands a local switch be included in the room where the fan is installed.
Housed in a convenient large junction box, the switch multiplier provides large terminals along with cable strain-relief. The switch multiplier has been tested and is compliant to AS/NZS3100 as well as having a motor rating of M2 (tested and compliant to AS/NZS 3133:2013 A1-A2 clause 13.13)
Pre-release information
C-Bus^ interface hat suitable for Raspberry Pi 4. Includes 2x RJ45 connections to C-Bus network. Connects to 40 pin header connection of raspberry Pi 4. Includes an interrupt relay to reset (break) the connection to C-Bus should the interface get into an indetermined* state. Instructions will be provided on how to connect to a locally running version of CGate or to remote access via the Local Area Network (LAN). The interface hat will enable the Raspberry pi/hat combination to operate in much the same way as a C-Bus Network Interface (CNI) unit.
Note.. This product will only be available through the online store and partner sites for the foreseeable future (not through electrical wholesalers).
*The indetermined state is a known problem where the PC interface fails to reset and will not connect to C-Bus toolkit or CGate. The only way to reset is to power cycle (disconnect from the C-Bus network, then reconnect). The interrupt relay has a set of normally closed (N/C) contacts that can be pulsed open to briefly disconnect. Instructions will be provided on how best to do this.
^C-Bus is a registered trade mark of Schneider Electric
