Type E and F
require 1 channel for each protected left turns (1, 3, 5, 7) and 4 channels for the 4 FYAs. The
MMU2 uses 16 channels to monitor the 8 phases and 4 Peds. This leaves 0 MMU2 channels available. Type
E and F uses the opposing Ped Yellow for the Protected Left Turn Green. Type E the MMU2 monitors and
displays the opposing Ped Yellows on channels 9G, 10G, 11G and 12G. Type F the MMU2 monitors and
displays the opposing Ped Yellows on channels 13G, 14G, 15G and 16G.
Type G and H
require 1 channel for each protected left turn (1, 3, 5, 7) and the Ped Yellow for the FYA.
The Controller
Unit must be able to use the Ped Yellow as a FYA. FYA Type G has the Peds on channels 9,10,11,12. FYA
Type H has the Peds on channels 13,14,15,16. The MMU2 uses 12 channels to monitor the 8 phases and 4
Peds in the FYA Configuration Type G and H. This leaves 4 MMU2 channels available. There is also less
cabinet rewiring, because the protected phase remains in 1, 3, 5, 7.
