REPLACEMENT OF BASE UNIT AND EXTENSION CABLE

5.3.2 Precautions for replacement of extension cable

(1) Overall cable distance of extension cable
An extension cable can be used up to 13.2m for the Q series while it can be used up to 6.0m for the
AnS/QnAS series.
Select a cable optimum for the system.
(2) Extension cable
The AnS series main base unit and extension base units, the A1S5B-S1 and the A1S6B-S1, have
two extension connectors (right and left) and the A1SJHCPU has one extension connector (right).
However, the Q series main base unit has one extension connector (left). When the main base unit and
extension base unit are located as below, the existing cable length may be not enough. Consider the
position in the control panel and select the cable which has the proper length.
• Configuration example when the base units are located to right and left
