Troubleshooting
Refer to the tables below for a list of error messages that may appear on the FACP display when using the IDNet 2 card:
Table 3: Trouble Messages
Trouble Message Possible Cause
Extra Device Appears if one or more extra devices (i.e., devices that have not been configured for the IDNet channel) are found on
the system, or if a device is at an incorrect address.
Note: An extra device on address 253 or 254 indicates that a Loop Module has been detected but not programmed.
Only one trouble message appears, regardless of the number of extra devices found. Viewing the trouble log reveals
the extra device address. Devices with LEDs will light their LED steady to indicate the trouble as long as no alarms are
present in the system.
Wrong Device Appears when the device detected at the address does not match what is programmed in the system.
Earth Fault Search Appears while the IDNet 2 card is searching for earth faults on the IDNet channel. When this message is displayed, the
IDNet1+ card cannot show any alarms or other statuses.
Channel Fail Appears when devices have been configured, but none of the devices are communicating on the channel. This
message does not appear if there are no configured devices on the IDNet channel.
No Answer Appears when a device is missing, damaged, improperly configured,
or duplicate devices are present.
Note: A No Answer trouble on address 253 or 254 indicates a loop module has been programmed but not detected.
Bad Answer Appears when there is a faulty device, a noisy communications channel, or duplicate devices are present.
Output Abnormal Occurs during any of these conditions:
• When 24 V is not present on IDNet devices (MBZAM and MAZAM devices for example).
• When TrueAlarm sensor bases with relay driver outputs are not properly supervised.
• When isolator devices are in isolation mode.
Note: Additional troubleshooting information about duplicate devices, weak answers and other problems may be obtained through panel diagnostics.
