Types of Controls for Nexus 21 Lift Systems
All Nexus 21 Systems come standard with a wireless remote control and receiver. We offer a choice of two different types of remotes:
IR and RF (both of which are explained in detail below). Our standard control type is RF, so unless you specifically requested the IR
version when you made your purchase, you probably received the RF controls with this Lift System. The method of installation for
each type of remote control is slightly different, so you should now identify which type of remote you have by reading below, and
then follow the instructions for that type of remote.
NOTE: If you will be using a system with a home control system (like the ones made by companies such as Crestron or Control 4) the
most common form of control is to WIRE IT DIRECTLY to the relays of your home control system. This direct-wire method is called
Integration by Contact Closure, and is accomplished by using the Contact Closure Hardware that is supplied with the IR Control Kit to
connect the Lift to your home control system.
Identifying the System Control Type
IR (Infrared) –This control option allows you to utilize a 3rd party universal style remote control to raise and lower the TV Lift.
Your universal remote will “learn” the IR codes from the provided IR Handset, which will enable you to control the lift. The universal
remote will then communicate with the “eye” located on the IR Receiver via your 3rd party emitter (or flasher). Instructions for
setting the travel limit for the system are on Page 21.
NOTE: If you are NOT planning on using a 3rd party Universal Remote, switch to the RF setup. (There is no charge for swapping)
These are the parts included with IR controls:
Contact Closure Hardware IR Receiver IR Handset Height Limit Insert
RF (Radio Frequency) - This system utilizes a wireless remote-control handset that sends a radio signal to the RF Receiver. The
radio signal can go through ceiling material and does not require line-of-sight. Instructions for setting the travel limit for the system
are on Page 21.
TIP: Planning to integrate the TV Lift with your UNIVERSAL REMOTE CONTROL? The RF version of the Nexus 21 controls won’t do it. Switch to IR.
These are the parts included with RF controls:
Backup Switch RF Receiver RF Handset Height Limit Insert
Integration by Contact Closure –To direct-wire the TV Lift controls to a home control system (Crestron, Control 4, AMX, etc.)
you will use the Contact Closure Hardware. You won’t use any Nexus 21 receiver or handset for this type of control because you will
use the handset or control pad that comes with your home control system. Instructions for setting up the System using Contact
Closure are on “Page 25”.
