CPU Motherboard Configuration
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Negative Ground Fault | Ground fault arising from the RUI shield connection on the CPU motherboard. | Some devices that connect to RUI have inherently grounded shield terminals, in which case 24 C cannot be used. If 24 C is used, a Negative Ground Fault will occur. | 30 |
LED/Switch Controller Card
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| COMM LOSS LED (LED1) | LED on the 64/64 LED/switch controller card. Illuminates if communication loss between the controller and the CPU occurs. It is independent of jumper P1 (which configures different communication loss features). | 38 |
NIC Card LED Indications
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| LED1 (yellow) | Illuminates when: the host CPU requests it to illuminate; a transmission fails; it is off-line with the host CPU; it needs to be configured. | 49 |
SPS Specifications
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Mains fail fault | AC mains supply supervision fault. | Generated when the DC voltage drops below 20.3V (nominally at mains voltage 204VAC). | 63 |

Troubleshooting an SPS
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| IDNet Power Monitor Trouble | Fault message associated with the SPS that may appear on the 4100ES-S1 display. | There is no output voltage from the power supply. | Refer to Chapters 2 and 5 for information on power supplies. | 67 |
| Extra Device | Extra devices detected on the IDNet channel. Only one message appears, regardless of the number of extra devices found. | One or more extra devices, i.e., devices that have not been configured on the IDNet channel, are on the system. | 67 | |
| Class A Trouble | IDNet channel trouble message. | There is an open circuit on the IDNet channel. | A hardware reset of the system is required to reset the fault. | 67 |
| Earth Fault Search | Displayed during the Earth Fault Search diagnostic function; the front panel display indicates how far the search process has progressed (10%, 25%… 75%), and then shows the results of the search. The result either identifies the offending circuit or indicates that the earth fault could not be found. | Earth Fault Search initiated; SPS circuits (IDNet, NAC, and aux power) are searched. | System alarm and trouble processing is suspended during the search. | 67 |
| Short Circuit | IDNet channel status message. | A short circuit is detected on the IDNet channel. | This status clears automatically when the short circuit is removed. | 67 |
| Channel Fail | IDNet channel status message. Does not appear if there are no configured devices on the IDNet channel. | At least one device on the IDNet channel has been configured, but no devices are communicating on the channel. | 67 | |
| No Answer/ Bad Answer | Device communication message. | The 4100ES-S1 is put into a diagnostic mode and finds a device not responding, or responding unreliably. | 67 | |
| Output Abnormal | Device output status message. | 24 V is not present on TrueAlarm devices, or TrueAlarm sensor bases with relay driver outputs are not properly supervised, or isolator devices are in isolation mode. | 67 | |
| Noisy Buzz from the SPS | Audible buzz from the SPS. | The SPS frame is held together with #6 screws; these may have loosened over time. | Tighten these screws as required, taking care to avoid damage to any part of the panel. If cards need to be removed for access to the screws, power the panel down first (mains and battery). | 67 |
Brigade Interfaces
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| SPS CPU Fault | Hardware signal to which the Fault (Trouble) relay on the Alarm Relay Card is link connected. For this reason, an Aux relay programmed as normally energised (de-energising on Fault) cannot be used to replace the Fault relay on the Alarm Relay Card. | The SPS loses communications with the CPU; the relay signals “Fault”. | 70 |
Using T-GEN 50 with 4100ES-S1
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| SPS Over Current | Fault produced in the system when the T-GEN 50 is first turned on. | The T-GEN 50 is powered from a NAC output and draws a large in-rush current when it is first turned on. | Can only be cleared by pressing the 4100ES System Reset button. The T-GEN 50 should not be powered from a NAC output. | 80 |
Using Install Mode
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| INSTALL MODE ACTIVE | Single fault point entry shown while any device is in the Install Mode list. Devices in the Install Mode list do not produce fault indications, even if they are missing or faulty; all the individual device faults are hidden behind this single fault. | Internal modules or external devices have been added to the Install Mode list during installation/commissioning while they are known to be missing or off-normal. | Adding/removing requires being logged in at Level 3. Remove individual devices via <More Info> → “Remove from Install Mode?”, or in bulk via Menu → Diagnostic Functions? → View/Modify Install Mode List? → “Move ALL NORMAL devices from install mode” or “Move ALL DEVICES from install mode”. When the system is fully commissioned, the Install Mode list should be empty. If a removed device is still in fault, the system fault count will increase and the Fault indicator will flash for a new fault. | 95 |
Programming Requirements
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Fault indication after 8 hours of isolate | Function that must be programmed under custom control to comply with AS 4428.1 (contained in the configuration templates): a fault indication is given after 8 hours of isolate. | An isolate has been in place for 8 hours. | 108 |
Earth Fault Detection
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| P438 | Trouble pseudo-point activated during an Earth Fault Search, while all related troubles are suppressed. | Earth Fault Search in progress; the 4100ES-S1 suspends normal operation for the duration of the search and alarm processing will be stopped. | The fire panel cannot provide fire protection during an Earth Fault Search. At the completion of the search, all slaves are restarted and normal panel operation resumes. Earth Fault Search detects only one fault at a time; multiple faults require fixing the first fault and then repeating the search. | 113 |
| CARD 17, ANALOG AUDIO CONTROLLER AUDIO RISER 1 EARTH FAULT | Example of a non-point fault result: a ground that cannot be traced to an addressable point (for example, a shield or an audio riser). Non-point faults can be displayed for: Channel Output (IDNet Card; MAPNET Interface Card); RUI Channel (Master Controller Card) — not used in 4100ES-S1; Channel 1 to 3 (TrueAlert Power Supply) — not used in 4100ES-S1. | An earth fault: an electrical circuit shorted to ground. | Once directed to the earth fault and it has been corrected, it is recommended that you restart the system (warm- or cold-start). | 117 |
| CARD 003, FLEX 50 AMPLIFIER 3-10-0 EARTH FAULT | Example of a point fault result: an earth fault at a specific addressable point (3 = card address, 10 = point number, 0 = sub-point number, not used). Point faults can be found at any point in the system that connects to field wiring. | An earth fault at the addressed point. | Once directed to the earth fault and it has been corrected, it is recommended that you restart the system (warm- or cold-start). | 117 |
| CARD 2, IDNET CARD (250 POINTS) M1, EARTH FAULT SEARCH FAULT CLEAR FAIL | “Fault not cleared”: an IDNet channel that has been isolated for fault detection still has the earth fault. | Earth fault still present on the isolated IDNet channel. | Correct the fault; once corrected, it is recommended that you restart the system (warm- or cold-start). | 117 |
| CARD 2, IDNET CARD (250 POINTS) M1, CHANNEL OUTPUT EARTH FAULT | Fault between the IDNet channel output and the first isolator on the line. | Earth fault on the channel wiring between the channel output and the first isolator. | Correct the fault; once corrected, it is recommended that you restart the system (warm- or cold-start). | 117 |
| CARD 2, IDNET CARD (250 POINTS) M1-3, IDNET ISOLATOR EARTH FAULT | Fault detected after the IDNet isolator was turned on. | Detected during an IDNet Channel Search, after the isolator was turned on. | Correct the fault; once corrected, it is recommended that you restart the system (warm- or cold-start). | 118 |
| FAULT NOT FOUND / FAULT CLEAR FAIL | Message in the lower right corner of the LCD: the search could not locate the fault, but it acknowledges that a fault exists. FAULT NOT FOUND for a Location Earth Fault Search; FAULT CLEAR FAIL for an IDNet Channel Earth Fault Search. | Possible causes: one or more internal wiring earth(s) in the system; system defects (hardware or software, such as a failed isolation circuit); an intermittent earth exists in the system (occurs inconsistently and is therefore difficult to track via diagnostics); the cable to the service port may be grounded due to the remote PC’s 3-pin plug; the fault is on an auxiliary output that was excluded from the search. | If the service-port cable earth is the cause, run the laptop on batteries only, or use an isolating transformer to the PC. The problem may have to be found manually and then corrected. Once corrected, it is recommended that you restart the system (warm- or cold-start). | 118 |
| NO FAULT | The IDNet channel search could not locate any earth faults on that channel. | 118 | ||
| RESULT NOT AVAILABLE | There is no result to view. This message comes up only when you have selected “Last Search Result” on the menu. It is also displayed if there has been no search since the last system startup, or if the last search was aborted. | 118 |
