(1) CH1_IN+/− from the control panel or previous annunciator. CH1_OUT+/− to the next
annunciator or to the control panel if the last annunciator on a Class A circuit.
(2) CH2_IN+/− from the control panel or previous annunciator. CH2_OUT+/− to the next
annunciator. Used only on redundant Class B circuits. See Figure 6 on page 8.
