B. Using the C-1000A with Three Doorboxes and No C.O. Line
The C-1000A can be used to control up to 3 doorboxes. If door/gate control is needed, the C-1000A must be used in
combination with the RC-3 Remote Controller (Fax Back Document 165). In this configuration, the optional RC-3 is
connected in parallel with doorbox 3 to provide up to three additional relay contacts. Note: Doorbox 3 will not have
Touch Tone dialing restriction (security). Be sure to program the RC-3and the C-1000A with different security codes.
