• AR1202 / AR602 Interface Provided

• Dimmed 120VAC + 120VAC Switched

The FL Series is a two or four channel controller add on product for the AR1202 Unity Architectural dimmer. It provides control

of dimmable uorescent lighting ballasts. The FL Series provides two or four 2400 Watt channels of uorescent dimming which

is interfaced to the AR1202 control circuitry. The AR1202 uses two or four of its auxiliary channels to control the FL Series. Dual
SCR “zero crossing” switching is used to control the switched hot lines. The FL Series is supplied in two versions: The “A”:
Controls ballasts which use a switched 120 VAC “hot” and a dimmed 120 VAC as a control signal. The “D”: Controls ballasts
which use a switched 120 VAC “hot” and a 0-10 VDC dimming control signal.

Architect & Engineer’s Specications

The units shall be a 2 circuit add-on product for the AR1202 dimmer. The unit shall provide two 2400 Watt circuits of uorescent

dimming which shall be interfaced to the AR1202 control circuitry. The AR1202 shall use 2 of its auxiliary channels (13 - 14) to
control the FL2020A. When installed, the unit shall become a fully integrated extension of the AR1202 and shall be addressed
and programmed as 2 normal dimming channels.

Dimensions are 12”W x 10”H x 4”D, the weight is 17.7 pounds.

The dimming system shall be a Lightronics FL2020A.
