§ 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).
♦ 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.

Current Consumption

Light Modules	Steady or Flashing LED	20 mA	22 mA	21 mA
Piezo Style Sound Modules	Single and Dual Circuit	53 mA	22 mA	21 mA
Flashing Frequency (Light Only Modules)
Flashing LED Modules		Flashing frequency approximately 2 Hz
dB Rating (Sound Modules)
All dB(A) ratings determined at a distance of 1 meter from sound module
