Managing Alarm Conditions
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| ***ALARM*** Press <FIRE ALARM ACK> to review. ALARMS = 1 ISOLATED = 0 FAULT = 0 | Fire alarm condition present. Red Fire Alarm and common Zone Alarm LEDs flash, the affected zone's red Zone Alarm LED flashes, the sounder (buzzer) pulses, the Emergency Warning System (EWS) and External Bell activate, and any programmed outputs including the Brigade connection operate. The display alternates between the point details and this summary. | An actuating device (such as a manual call point, smoke detector, heat detector, etc.) has activated in a non-isolated zone. | Press <FIRE ALARM ACK>: the buzzer silences and the Fire Alarm indicator changes from flashing to steady ON (the Zone Alarm indicator continues to flash until the zone is isolated or reset). When the condition is cleared, press <SYSTEM RESET>. If the alarm won't reset, the point may still be activated: press <FIRE ALARM ACK>, then <DISABLE>, <ENTER>, press <FAULT ACK>, then <SYSTEM RESET> again; the disabled detector must be re-enabled when the condition is cleared. | 21 |
| ACF ISOLATE PRESS <ACK> key to acknowledsge | The Ancillary Control Facility (ACF) relay outputs, used to control equipment that is not part of the fire alarm system (shutting down air conditioning, returning lifts to a certain floor, door holders, security trips, etc.), are isolated. The ACF ISOLATE indicator is lit and the Isolate indicator above the Isolate Ack key flashes until acknowledged. | The ACF ISOLATE key was pressed, e.g. during maintenance or testing to prevent unwanted annoyance to building occupants. | Press the Isolate Ack key to acknowledge. Isolation takes effect immediately from pressing the ACF ISOLATE key, not from when the Isolate Ack key is pressed. Press the ACF ISOLATE key again to restore the outputs; note that if any alarm conditions are still active, the ACF outputs will operate as programmed. | 23 |
| Alarms Present – System Reset Aborted | The system attempted to reset a point for 25 seconds (displaying "System Reset in Progress") and aborted because the point failed to clear — alarm conditions are still present. | The condition that caused the point to go into alarm has not been cleared (e.g. smoke not cleared from smoke detectors, glass not replaced in manual call point). | Clear (fix) the condition that is causing the alarm, or disable the point from the panel (select the point with <ALARM ACK>, press <DISABLE>, <ENTER>), then press <SYSTEM RESET> again. The disabled detector must be re-enabled when the condition is cleared. | 26 |
Managing Fault and Isolate Conditions
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| **FAULT** Press FAULT ACK to review. ALARMS = 0 FAULTS = 1 ISOLATES = 0 | One or more fault conditions are present. The yellow FAULT indicator flashes and the sounder (buzzer) sounds steady until acknowledged. Pressing <FAULT ACK> or <NEXT>/<PREVIOUS> shows each fault's custom label, the type of device, and the type of condition. | Something wrong, e.g. the presence of a field wiring problem (circuit break, short or ground) somewhere between the 4100ES and one of its points; a problem with the option cards, power supplies, network card, etc.; disabling a point also introduces a fault condition into the system. | Press <FAULT ACK>. With Global Acknowledge, all currently active faults are acknowledged, the message "Global Acknowledge" is displayed for approximately two seconds, the sounder turns off and the FAULT indicator changes to ON steady. With Individual Acknowledge, only the displayed fault is acknowledged; if additional faults remain the sounder does not turn off and the FAULT indicator continues to flash — use <NEXT>/<PREVIOUS> and <FAULT ACK> for each. Most faults automatically clear when the problem causing the fault (wiring, device, etc.) has been fixed. | 29 |
| ISOLATE (yellow ISOLATE indicator flashing) | One or more zones have been isolated — an abnormal, non-fire condition. The yellow ISOLATE indicator flashes and the sounder (buzzer) sounds steady until acknowledged; the LCD gives confirmation that the correct zone has been isolated. | Zones manually isolated by an operator with the Zone Isolate pushbutton, e.g. to prevent a false alarm when maintenance work (building repairs, welding, etc.) is being done in an area. | Press the <ISOLATE ACK> key (global or individual acknowledge per configuration). De-isolate by pressing the Zone Isolate key so the Zone Isolate LED turns off, then acknowledge the de-isolate operation if individual acknowledge is programmed. Note: zone isolate status is not stored in non-volatile memory — if the panel is powered down and back up, or the CPU is reset, all zones will be de-isolated. | 28 |
| Open circuit fault on IDNet communications line (latching) | A latching fault: it remains in the system until it is reset manually, even after the wiring/device problem has been fixed. | Open circuit on the IDNet communications line. | Fix the fault condition (wiring, device, etc.), then reset manually or clear by pressing the <SYSTEM RESET> key. | 29 |
Testing and Controlling Points
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| System Fault — point disabled | A fault condition and message indicating that the point is disabled (taken "offline"). A disabled point cannot enter an alarm condition for the duration of time it is disabled. | The point was disabled with <DISABLE> + <ENTER> — e.g. a malfunctioning detector causing false alarms, or an activated detector that prevents the system from being reset; also performed when an IDNet point will not reset. | Acknowledge with <FAULT ACK>. When the point is repaired, re-enable it: select the disabled point (e.g. by repeatedly pressing <FAULT ACK>), press <ENABLE> then <ENTER>. The system displays a message indicating that the point will be enabled in 60 seconds; if an alarm condition will occur when the point is enabled, the system warns you and you can abort with the <DISABLE> key. The disabled detector must be re-enabled when the condition is cleared. | 8 |
| Manual Override Fault | Reminder that an output point (notification device, relay) has been manually turned ON or OFF and is no longer under automatic panel control. | An output point was forced ON (<ON> + <ENTER>) or OFF (<OFF> + <ENTER>). | Acknowledge the fault by pressing the <FAULT ACK> key. Return the point to automatic operation with <AUTO> + <ENTER> — a fault exists if any control point is taken out of the AUTO state. Exception: control points that are normally off (e.g. Sonalert (buzzer) Inhibit, point P198) must later be restored to "off", not "auto". | 35 |
Displaying and Modifying Detailed Point Attributes
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Class A Fault (Status of Class "A" Cards) | Display-only attribute (via <MORE INFO>) showing whether the Class A card is experiencing a fault somewhere in the wiring between the card and its devices. | Fault in the wiring between the Class A card and its devices. | 42 |
Setting Access Levels and Logging In
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| ERROR. . . INVALID PASSCODE | The passcode entered for the "Change Access Level?" option is not a valid system code. | Invalid passcode input. A valid passcode contains a minimum of 3 and not more than 10 digits (0 through 9); default passcodes are 222 for level 2 and 333 for level 3. | You are allowed up to three chances to enter a valid code. While entering, digits are masked with an X; the <DEL> key deletes the last digit; <ENTER> submits the passcode. | 48 |
| ACCESS DENIED | Three unsuccessful passcode attempts; the access level will not be altered. | Three invalid passcode entries. | The message is displayed for a short time; you will no longer be in the "Change Access Level" menu option and the access level is unchanged. | 48 |
| Non-clearable fault — access level 4 login | A non-clearable fault exists while logged in at access level 4. It ensures that the system is returned to its normal operating mode following service. | Logging in at access level 4 (the highest level, used by Simplex-trained personnel). | Requires the system to be restarted (the CPU card is reset) to clear. If the fault persists after exiting Walk Test at access level 4, call a Simplex-trained technician to restore the system. | 50 |
System Test Procedures
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| No walk test points configured for: WALK TEST GROUP X | The selected Walk Test group (X equals 0 through 7) has no configured points. | A Walk Test group was selected/enabled whose Monitor Zone List is empty — an empty list signifies that a Walk Test group is not used. | 73 | |
| System Fault — Walk Test enabled | Reported to remind you that the Walk Test is enabled: the SYSTEM FAULT LED illuminates, the tone-alert sounds, and the enabled group's associated fault pseudo point is turned ON and must be acknowledged. | A Walk Test group was enabled with the <1> key in the Enable Walk Test menu. | Once all required Walk Test groups are selected, press the fault acknowledge key. When exiting Walk Test mode, the system activates a one-minute timer to ensure monitor points have had ample time to clear prior to enabling the system; after the one-minute delay the system Walk Test fault automatically clears. If Access Level 4 was entered, a fault will continue to exist — call a Simplex-trained technician. | 73 |
| ** FAULT ** Press <FIRE ALARM ACK> to review FIRE = 0 PRI2 = 0 SUPV = 0 FLT = 1 | System fault summary (FLT = 1) shown after a control point is forced OFF; the same display appears after forcing a point ON. | A control point was taken out of the AUTO state with the <OFF> key (or <ON> key) followed by <ENTER>. | Press <FIRE ALARM ACK> to review and acknowledge the fault. Return the point to automatic control with <AUTO> + <ENTER>; the display then returns to SYSTEM IS NORMAL. | 74 |
| MONITOR CARD 1 ZONE NUMBER 12 FIRE MONITOR ZONE DISABLE FAULT | The monitor zone point is disabled. The disabled point causes a system fault condition which is continually shown on the alphanumeric display and can be viewed by pressing the <FAULT ACK> key. | The point was previously disabled (e.g. a device that was disabled and has now been restored, ready to be re-enabled). | Press <ENABLE> (display: "Press <ENTER> to ENABLE / MONITOR ZONE: ZN12"), then <ENTER>: "Please stand by . . . ZONE 12 will ENABLE in 60 seconds". If the zone is still in alarm a warning is displayed — abort with <DISABLE>. If the enable process is successful, "ENABLE COMPLETED" is shown. | 76 |
| ** WARNING ** Press <DISABLE> to abort ZN12 will ALARM in 60 seconds | Warning that the zone being enabled is still in alarm and that the system will sound an alarm if the 60-second enable timer times out. | <ENABLE> + <ENTER> was pressed on a disabled point while its zone is still in an alarm condition. | TO ABORT THE ENABLE, PRESS THE <DISABLE> KEY (or the <FIRE ALARM ACK> key). FAILURE TO ABORT THE ENABLE WILL CAUSE AN ALARM CONDITION. | 77 |
Printing Reports
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Current State: Normal, Fault, Dirty, Excessively Dirty, Almost Dirty | Possible per-point sensor states reported on the TrueAlarm Service Report. The TrueAlarm Status Report also has an Almost Dirty Status field in which points which are almost dirty are denoted with an asterisk. | Sensor contamination (almost dirty, dirty, excessively dirty) or a point fault. | 81 |
Maintenance Procedures
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Power supply supervision fault | Power supply supervision fault condition of the control and indicating equipment (AS 1851 Item 2.3). Where the CIE is monitored, the fault is processed by the monitoring service provider; where the CIE is a sub-CIE, the fault condition is indicated at the fire CIE. | CIE operating voltage reduced below the minimum operating voltage. This test requires equipment external to the 4100ES. | Trigger and verify using a suitably rated bench power supply connected to the battery terminals with mains power turned off, reducing the output voltage below the minimum operating voltage; confirm that the fault is processed by the monitoring service provider or indicated at the fire CIE. | 85 |
