Low Voltage Controllers: FAQ

What type of wall dimmer switch is used with your LVC-2000?

The only switch that can be used with our LVC is a normally open dry
contact that is wired in parallel with the pillow speaker or bed. The
microprocessor sends a 0-10V signal to the driver.  This signal tells
the driver how to dim.

How do you wire multiple switches to one light?

The switched must be wired in parallel to the respective inputs
on the low voltage side of the controller. All switches shall share a
common and are to be wired to the brown terminal on the Low Voltage
Switch Input side of the LVC.

How does a pillow switch with one light button dim up and down?

LVC-2000-004 Bi-Directional LVC:
The pillow speaker light button is a normally open dry contact. When the
button is initially pressed then released the LVC will activate the
respective load and set the dim output to 25%. The next sustained press
will begin to dim the light up (max 100%), a release and second
sustained press will begin to dim the light down (Min 13%).  Any release
and additional sustained presses will continue to change dimming
direction between 100 and 13%. A quick (or momentary) press and release
turns the light off

LVC-2000-001 Dimming LVC:
The pillow speaker light button is a normally open dry contact. When the
button is initially pressed then released the LVC will activate the
respective load at 100%. A sustained press will begin to dim the light
down to off in 13 half second steps. Any release will stop the dimming.
The next sustained press and hold will continue the dimming towards off.
Once off, the next press and release will turn the light back on at
100%.

Do you have a LVC that controls up to five lights?

We do not. In order to control five lights you will need to have two low voltage controllers.

Will your LVC work with all nurse call systems?

Yes, all modern nurse call systems.

Do you sell wall switches?

Yes, we have a complete line of membrane wall switch options. Click here for more information.

Can a healthcare bed dim a light?

Yes, as long as the light switch on the bed is a normally open dry contact and is wired in
parallel with the associated pillow speaker or wall switch
