INSTRUCTION/INSTALLATION SHEET
HMS EZ-SCENE ALC LIGHTING INTERFACE
IS-0311 REV. A
4. Operation
Upon powering up the EZ-Scene Interface, the STATUS LED
indicator will blink at a rate of approximately 1 blink per second.
If the STATUS indicator remains On or Off, it is an indication
of a fault. In the event of a fault, check all connections and
power to the HMS Controller.
Subsequent to making any alterations to the system, such as an
address change to an ALC control, the EZ-Scene Interface
should be reset. Resetting can be accomplished either by
removing power or by momentarily pressing the RESET button.
Note: Remove power to the Interface prior to connecting new
devices. Verify all connections prior to restoring power
The ACTIVITY LED indicator serves as a diagnostic feature.
The ACTIVITY LED will blink whenever ALC control activity
is detected. The LED will also blink when activity is detected at
any of the four inputs. The ACTIVITY LED is particularly
useful in verifying proper connection of ALC controls. When
any properly communicating ALC switch button is pressed or
any properly connected input is activated, the ACTIVITY LED
indicator will blink in response to the event.
HMS Lighting Control
Complete instructions for controlling and programming ALC
controls from the HMS Controller and configuring the HMS
controller for EZ-Scene Interface operation, can be found in the
installation and owner’s manuals included with each HMS
controller.
Programming Local Lighting Scenes
A total of 64 lighting scenes can be programmed into each EZ-
Scene Interface. All memorized lighting levels are retained in the
EZ-Scene Interface’s memory (EEPROM). All scene programs
are preserved in the event of a power outage. Local lighting scene
programming and operation is not limited by the unit control
capacity of the HMS controller. For example, although the
HMS Model 800 controller is limited to control of 16 ALC
controls, up to 124 ALC controls can be included in locally
programmed lighting scenes.
Note: Up to two EZ-Scene Interfaces may be connected to an
HMS Model 1100 controller, however local lighting scene
programming of each EZ-Scene Interface will function as an
independent area.
The EZ-Scene Interface is placed into “Scene Learning Mode” in
order to define the ALC lighting levels for a local lighting scene
program. The user places the system into “Scene Learning
Mode” by pressing and holding any ALC Scene Switch button
or pulling Inputs 1 - 4 low (GND) for 15 seconds.
The LED indicator on the ALC Scene Switch blinks
continuously when the button has been held long enough.
Additionally, the EZ-Scene Interface module’s ACTIVITY LED
indicator will blink continuously to indicate that “Scene
Learning Mode” has been entered.
After 15 seconds, the user should release the button or input to
allow it to return to its normal state. The user then sets all
lighting levels to be controlled by the lighting scene. The user
must press each ALC Dimmer, Relay Switch or Non-Dimming
control if it is to be included in the new local lighting scene
program. The final output level of the selected ALC Dimmer,
Relay Switch or Non-Dimming control will be stored in the
local lighting scene program.
After setting all lighting levels of ALC controls that are intended
to be included in the new local lighting scene program, the user
should momentarily press and release the button to complete the
programming operation. The EZ-Scene Interface’s ACTIVITY
LED and the ALC Scene Switches’ LED indicator will stop
blinking when the system leaves the Scene Learning Mode.
Programming of the new lighting scene is now completed and
stored in EEPROM memory.
While the system is in Scene Learning Mode, no other system
functions may be performed during this time. If the user does
not complete programming of the local lighting scene within 10
minutes, the system automatically leaves the Scene Learning
Mode and no changes are made to any local lighting scenes.
Restoring Local Lighting Scenes
To restore a locally programmed lighting scene, the user
momentarily presses and releases the desired Scene Switch or RF
Remote Control button. All ALC lighting controls belonging to
that scene are then set to their programmed levels. ALC lighting
controls not belonging to the scene are not affected when the
scene is restored.
Re-Programming Local Lighting Scenes
To change the ALC lighting controls or levels that are included
in a scene, the user simply repeats the scene programming
process. The lighting levels for the new local lighting scene will
replace the old ones. To remove a local lighting scene from any
button or input, simply enter Scene Learning Mode then press
that button or input again without changing any lighting levels.
That button or input will then be assigned an “empty” scene.
Warranty
On-Q warrants to the end-user, each new HMS EZ-Scene ALC
Lighting Interface to be free of defects in materials or
workmanship for a period of one year from the date of original
purchase from On-Q or its authorized reseller or installer. Each
product is deemed warrantable under conditions of normal use
and when installed and operated within On-Q specifications and
in accordance with the applicable National Electrical Code.
When determined to be warrantable, On-Q shall at its option
and expense, replace any defective product with a new or
reconditioned product. On-Q will continue to warrant any
replaced product for a period of ninety (90) days from shipment,
or through the end of the original warranty period, which ever is
longer.
