Step 4. Lockout number 2 (if required): the green wire functions in the same way as the white
wire; see above. The green wire lockout signal could be triggered by a different set of alarms
than the other lockout wires. See lockout code table on the next page.
Step 5. Lockout number 3 (if required): the orange wire functions in the same way as the white
& green wires; see above.
Step 6. Optional Lockout number 4: if purchased with the fourth lockout option, the blue wire
will function in the same way as the white & green wires, see above.
Step 7. Connect the yellow cable to the GS550. The connector is waterproof and well rated for
external environments. Simply connect the cable to the display and gently tighten the nut. Do
not put a kink in the yellow cable where it enters the connector; any bend in the cable at the
base of the connector must not be so severe as to break the internal connections where the
cable meets the connector.
