The FL Series is a two or four channel controller add on product for the AR1202 Unity Architectural dimmer. It provides control
of dimmable fluorescent lighting ballasts. The FL Series provides two or four 2400 Watt channels of fluorescent 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.
