Wiring for detector
Accessory cables (power cable and signal cable: with dedicated connectors, 5 m) are
processed with the crimp terminal at the terminal end, and indicated with marks shown in Fig.

When the cable length is insufficient, extend it by a relay box.
The relay box and the extension cable are to be prepared by the customer.
For the contact output for each detector condition, refer to “ Contact output ” (page 6).
