Clear Fault Alarms:
Press the – button on the ICore facepack to clear the Fault
message and/or Alarm light.
Special Notes:
ICore Decoders are not compatible with mechanical relays.
When combining DUAL48M with conventional ICore station
output modules, not all stations will be available for decoder
addressing. The station numbers for slots with ICM-600 modules
will not be available for decoder station programming.
Voltage measurement between an active decoder and the
solenoid is not a reliable indicator of the output from a decoder.
• Decoder electrical power is not the same as 50/60 Hz power
and normal voltmeters may show very low readings to active
stations (may range from 5 to 14 Volts).
• It is more reliable to keep a known-good decoder, and a
known-good solenoid, for troubleshooting purposes.
Controller may temporarily fault Open if only one decoder is
connected to the two-wire path, since standby current may
fluctuate below the minimum. Correct by either waiting 5 minutes
for line to stabilize, or connecting a second decoder.
Stations turned on in the field with ICD-HP may shut down
prematurely, because the controller is unaware of the decoder
activation. To prevent this, start another station via the controller
or remote control anywhere in the system.
