RS485 User Interface (UI)
If no communication has been established, check the wiring to be sure
that the polarity is not reversed on the two wires. The network can
be daisy chained, but it does require two 120Ω terminating resistors
in order to minimize reections. One resistor should be placed at the
controller or buss arbiter. The other resistor should be placed at the
farthest location from the controller or buss arbiter. RS485 allows up to
4000 feet of 24 AWG twisted-pair wire driving into 120Ω loads.
Service and repair
Contact Firey AB or your Firey AB distributor for details on our
customer support and repair services. Prior to returning defective
material, please contact the Firey AB service and repair department
for additional procedural information.
Model 660 and 860 ame detectors are not eld-serviceable and the
ameproof joints are not intended to be repaired. An unauthorized
attempt to repair or re-calibrate a detector will void the warranty.
Detectors should be carefully packed to avoid damage from shock,
moisture and dust. Use the original shipping carton, if available. Wrap
the detector in plastic before packing. Provide ample packing material
to cushion the detector.

The warranty period is thirty-six (36) months for the Model 660 and
860 Series Flame Detectors and ve (5) years for both the UV and IR
Sensors.
