‡ Sound module types (C, P, Q) must be on the top-most level, they must be configured with Lens Color/Sound Code 1, and only one sound module is allowed per assembly.
§ Light module types (Y, L) can only be configured with Lens Color/Sound Codes 3, 4, 5, 6, 7, or 8.
§ If the dual circuit sound module (Q) is selected, the maximum number of light modules allowed is three (two circuits are required for the dual circuit sound module).
Ø The SC20 cable must be ordered for all bases, except the Q10 and Q25 bases.

‡ Light Output values are calculated from the LED datasheet and show typical values of luminous density. These values are not exact because the knurling in the lens affects the light distribution and because the viewing angle of the LED which directly relates to the Cd output value, is not identical for all LEDs.
