Columbia LIGHTNING MPS4-40ML-F-W-EDU-ELL14 DTS Dimming Bypass Module
OVERVIEW
The DTS is a dimming bypass module used with an inverter or generator in emergency systems. The DTS works by constantly sensing for the presence of utility power. When utility power is no longer sensed (during a power outage), the DTS will bypass any dimming or controls integral to or networked with the fixture. Fixtures that can be dimmed must return to an undimmed (or pre- determined) state with loss of utility power, to meet UL924 requirements.
LUMINAIRE USE
The DTS cannot be used in conjunction with GTD, ATSD or ELL14/40 (Emergency
Battery Pack) options. Each luminaire has different restrictions of use,
please check individual specification sheets for compatibility. The DTS is
available only as a factory-installed option.
EMERGENCY CIRCUITS
While the DTS is UL924 listed, it is not used to transfer power. The transfer
of power must happen through a UL1008 module, (such as an AETS – Automatic
Emergency Transfer Switch), to meet building code. The DTS is to be used in
conjunction with an emergency AC power supply, such as an inverter or
generator. These systems are designed/specified by qualified professionals.
CONNECTIONS FROM FIXTURE TO BUILDING SYSTEM
The following 10 cases are outlined in the included wiring diagram package if
further information is needed. The following outlines key connections to
perform when installing new fixtures, as well as wiring internal to the
fixture.
EXAMPLE OF BASIC SYSTEM LAYOUT
Below are 3 situations of a system layout using a DTS module
- Specific layouts may vary
SITUATION 1 (below)
- Normal Undimmed Operation
SITUATION 2 (pg. 3)
- Dimmed Operation
SITUATION 3 (pg. 4)
- Emergency Operation
SITUATION 1: NORMAL UNDIMMED OPERATION
- Each luminare has in-fixture control and is not dimmed
- Luminaires 3 & 4 are also emergency enabled with DTS modules
SITUATION 2: NORMAL UTILITY POWER OPERATION, INDIVIDUAL DIMMING CONTROL
- Luminaires 1 & 3 are in a dimmed state by user choice
SITUATION 3: LOSS OF UTILITY POWER
- Transfer switch will transfer power from utility to emergency power source
- Luminaires 1 & 2 lose power
- DTS opens dimming circuits in luminaires 3 & 4 which then resume their undimmed state to meet UL924 requirements
CASE 1: DTS WITH EXTERNAL DIMMING CONTROL
CASE 2: DTS WITH INTERNAL NXFM-O OR NXFM-I
CASE 3: DTS WITH INTERNAL NXFM-LV
CASE 4: DTS WITH INTERNAL CTC MODULE FOR SpectraSync™
CASE 5: DTS WITH INTERNAL CTC AND NXFM-O OR NXFM-I FOR SpectraSync™ USED WITH NX
CASE 6: DTS WITH LUTRON H SERIES DRIVER OR LUTRON 5 SERIES DRIVER
CASE 7: DTS WITH INDIVIDUAL FIXTURE LVR OR LVS SENSOR
CASE 8: DTS WITH INDIVIDUAL FIXTURE ODPG SENSOR
CASE 9: DTS WITH FLEX
CASE 10: DTS/NXFM-0/I WITH FLEX
