A : No, a single emergency powered driver should be used with an Athena wireless node. Please refer to Application Note #106 (Lutron P/N 048106) Emergency Lighting Systems App at www.lutron.com for detailed diagrams covering both DALI and 0–10 V- emergency applications.
Q : Can the Athena wireless node respond to a Fire Alarm Control Panel signal?
A: Yes. Add a QSE-IO to every system and setup a meeting with the MEP and the local System Sales Engineer.
Q: What are some best practices for installing the Athena wireless node in a hard ceiling on a downlight or linear recessed fixture?
A
- Install in accordance with all applicable electrical codes. Athena wireless node must be accessible for service.
- If possible, have a way to service the Athena wireless node through the aperture, i.e., mount Athena wireless node on a removable plate that can be unscrewed and removed through the aperture.
- The front of the Athena wireless node should always extend outside of the fixture or enclosure following all “exclusion zone” requirements on the Athena wireless node specification sheet.
Q : What are some other mechanical best practices when using the Athena
wireless node?
A : Hole diameters and panel thicknesses defined in the specification
sheet are hard limits, beyond which there is no guarantee of mounting
robustness.
- Excessive paint on the fixture may make the panel too thick, or the hole too small.
- Burrs on the edge of the hole may interfere with the mounting snaps.
- Burrs inside the hole from pop-out discs may cause the inner diameter to be effectively too small.
- Non-round holes may reduce mounting performance.
- Non-flat panels may reduce mounting performance.
- Push the units all the way into their holes during installation.
- Do not hit units from the back to remove them. Depress the snaps and then gently wiggle the units out of their holes.
Q : Can the Athena wireless node be installed in the driver compartment
of a downlight fixture? What are the requirements to do this correctly and
what codes / standards are referenced? Does it need to be Class 1 rated to be
in the driver compartment?
A : For installation at the OEM: Requires approval based on the end
product standard to which the luminaire is evaluated. UL1598 6.18.1.1 states
“6.18.1.1 Factory-installed power limited wiring and branch circuit wiring
that come in random contact within the luminaire shall have insulation rated
for the maximum voltage that exists in any of the circuits.” This is an item
the OEM should confirm with the certifying agency specific to their device.
Q : Is there a list of compatible drivers?
A : No. The driver must be either: DALI-2 certified (for static white) or
DALI-2 Device Type 8 certified (for tunable white applications) or ANSI C137.1
for 0–10 V drivers.
- Separately, ensure the power requirements of the Athena wireless node are met by either: 1) the D4i or on-board auxiliary power supply or by 2) a secondary supply such as the Lutron DFC-OEM-DBI (used for both DALI-2 and ANSI C137.1 0–10 V drivers).
Q: Am I able to use the LED engine output of the driver to power the
Athena wireless node?
A: No.
Q : Am I able to use the LED engine output of the driver to power the
Athena wireless node or use a 2-channel driver and program one of the outputs
to CV to power the Athena wireless node?
A : No.
Q : Can an Athena wireless node be installed in a ceiling tile outside of
a fixture or in a junction box?
A : This is not a supported use case at this time.
Q : Is there a suggestion for handling continuous runs of linear
fixtures?
A : One Athena wireless node per zone of control per fixture section with
consideration of energy codes, requirements such as daylighting zone and
occupancy sensor coverage areas, as well as node-to-node RF range.
- Please reference the specification sheet for information on the minimum spacing between Athena wireless nodes.
Q : With 0–10 V- drivers, what is the control voltage for low-end light
level and what voltage is turn-on vs turnoff? Are these configurable in the
Athena wireless node through the Lutron Designer software for Athena or do
they need to be set in the driver?
A : Per ANSI C137.1:
- Turn-on voltage is set by the driver manufacturer.
- Any voltage below 0.8 V will be off (standby mode), the driver must have “dim-to-off” voltage at or above 0.8 V.
- The driver defines what the turn-off voltage will be. The Athena system is capable of trimming the low-end of the dimming output to eliminate “dead travel” inside the Lutron Designer software for Athena at system startup.
Q : Can I power more than one Athena wireless node with the DFC-OEM-DBI?
A : No. There can be only a single Athena wireless node connected to each
DFC-OEM-DBI.
Q : How do multiple LED drivers wire to a single Athena wireless node?
A : Please see the Athena wireless node specification sheet for details
concerning how many drivers can be connected to a Athena wireless node.
- DALI driver with D4i-compliant self-powered link power supply
- DALI driver without self-powered link power supply
- ANSI C137.1 0–10 V- driver with compliant built-in auxiliary power supply
- ANSI C137.1 0–10 V- driver without built-in auxiliary power supply
