Using the Motion Sensor 360 range with Crestron
In this blog we are going to look at how to connect the Faradite Motion Sensor 360 range to Crestron systems. Crestron is one of the largest and most established control solutions on the market with endless possibilities.
We are going to look at connecting the Faradite Motion Sensor 360 - Volt Free to 3 Crestron devices: the DIN-AP3, the C2N-UNI8IO Universal keypad interface and the GLS-SIM Sensor integration module.
The range of applications the PIRs can be used to trigger within Crestron are virtually endless but typical examples of motion based events would be automatic lighting, automated heating override or security alerts.
The wiring diagrams in this blog show the Faradite Motion Sensor 360 - 0-10V and the Motion Sensor 360 - Volt Free (the same terminals on the Faradite Motion Sensor 360 - IP67 means these diagrams also apply)
Wiring the Sensors
We advise using CAT cable to wire the sensors back to the Crestron unit. (Either CAT5, CAT6, or CAT7) the solid core on these cables should allow you to simply push in the cores to each terminal once each core has been stripped back. If using a stranded cable type we advise inserting the SIM card remover tool in to the terminal block to release the spring loaded connector before inserting the stranded cable. This will ensure the cable doesn’t ruck up when inserting.
Faradite motion sensors provide a normally open contact which is connected to the inputs on the Crestron system.
We are going to look at connecting the Faradite Motion Sensor 360 range to 3 Crestron devices - the DIN-AP3, the C2N-UNI8IO and the GLS-SIM Sensor Integration Module.
The DIN-AP3 can be used with both the Motion Sensor 360 - Volt Free and the Motion Sensor 360 - 0-10V. Let's start with the volt free variety and how to connect it:
The Motion Sensor 360 - Volt Free requires power from 5 - 35V DC for power, ideal as the Crestron system runs on 24V DC. Take the 24V DC to provide power to the Motion Sensor 360 - Volt Free. The output relay of the sensor should then be connected across the ‘G’ terminal and the appropriate input, in this instance ‘1’.
It is essential that when using the Crestron DIN-AP3 with the volt free sensor the pull up resistor is enabled on the input channel with the volt free sensor connected.
The Motion Sensor 360 - Volt Free can now be commissioned in the Crestron system for motion based automation.
The DIN-AP3 can also be configured to accept the 0-10V output and the digital output of the Motion Sensor 360 - 0-10V:
Power the sensor with the 24V DC and ensure the ground is common between the sensor, power supply and the Crestron DIN-AP3, this is to ensure the ground reference voltage is the same across all devices and the 0-10V reading is always accurate.
The ‘L’ terminal is the lux output (0-10V analogue output) of the Motion Sensor 360 - 0-10V and this can be wired to any of the inputs on the DIN-AP3. In the diagram below we are using input ‘2’. The input connected to the 0-10V output of the sensor should have the pull up resistor disabled. This allows the input to properly read the 0-10V analogue value, which once connected, can be commissioned to report the sensors brightness to the Crestron system.
The ‘M’ output of the Motion Sensor 360 - 0-10V is the motion output. This is a digital output relay which closes for the duration of motion +1 second. This can be wired to any of the inputs on the DIN-AP3 and in the example below we are using input ‘1’. On this input the pull up resistor should also be disabled. Once terminated the motion sensor can be commissioned in the Crestron system to provide automation as required.
The C2N-UNI8IO allows the connection of keypads to the Cresnet control network. The C2N-UNI8IO sits on the Cresnet network and allows the connection of up to 8 Faradite Motion Sensor 360s.
The DIP switches on the C2N-UNi8io are not relevant for this example as they control the outputs not the inputs.
The Sensor can use the 24V and ‘G’ terminals on the C2N-UNI8IO for power - connect these to the coinciding terminals on the Faradite Motion Sensor 360 to power the sensors.
Next connect one side of the motion sensor output to the second ‘G’ terminal on the C2N-UNI8IO and the other side of the motion sensor output to the numbered terminals, in this example terminal 1.
The sensor now has power from the device and the output is connected to the ‘1’ terminal on the C2N-UNI8IO.
This sensor is now ready for programming in Crestron.
Another great Crestron device for motion sensor connection is the Crestron GLS-SIM Sensor integration module. This tiny module allows the connection of up to 2 sensors to the Cresnet bus.
The module needs to be configured for 2 digital inputs in a normally open mode. To achieve this configuration, we need to set all the DIP switches to OFF.
To power the sensor take 24V from the GLS-SIM sensor terminal and connect the ‘-‘ terminal of the sensor to the ‘G’ terminal on the GLS-SIM
For the motion sensor output connect one side of the motion sensor output to the ‘1’ terminal on the GLS-SIM and the other side of the motion sensor output to the ‘G’ terminal (this terminal is also providing GND for the 24V power).
Once the connections have been made you can now use the sensor in Crestron to create the required automation.
Please note: Both modules outlined in this blog are bigger than the 35mm hole required for our sensors. We recommend wiring the sensor back to a location where the module can be inserted into the ceiling e.g. a speaker or downlight, or we recommend putting the unit in the ceiling prior to the plasterboard being added.
