Loop Messages

This table provides descriptions for loop device event/messages.

Message Description
**ALARM**Applies to a loop input device – detector, Manual Call-Point, or input module; when the device activates. The alarm may be one of the following:
Smoke either an intelligent smoke detector or a conventional smoke detector activation from a Loop Responder input.
Call-Point either an MCP-type device or a Manual Call-Point activation from a Loop Responder circuit.
Heat thermal detector.
FaultGenerally, Faults can be decoded to one of the causes listed below, however for some events this is not possible.
Pre-AlarmApplies to detectors only. The analogue value being returned is approaching the Alarm level.
Duplicate DeviceTwo loop devices on the same loop have been assigned the same address.
MissingA loop device that has been configured in the system memory is not present on the loop.
Extra DeviceThe loop driver board has detected one or more of:  
  • Device(s) that don't exist in the panel configuration
  • Device(s) with loop address 000 (or 00 for modules)
  All detectors set to address 000 will have their LEDs turned on as though in alarm.
Modules set to address 00 will not have their LEDs turned on.
Maintenance AlarmThe loop driver internal drift compensation has reached its threshold limit - the detector requires cleaning.
Type MismatchA loop device does not match with the configuration assigned to it in the system memory.
Self-Test FailA loop device has failed its regular auto test.
DISA loop device has been isolated through the DISABLE push-button on the front panel display or the User Menu.
Alarm ResetA loop device that was in 'Alarm' has been 'Reset' through the RESET push-button on the front panel display.
Low DefectGenerated by sensing chamber defects in System Sensor detectors
High DefectGenerated by sensing chamber defects in System Sensor detectors - this can mean that the chamber is too dirty for the detectors internal drift compensation algorithm to operate.
Short CircuitA monitored relay has a short-circuit.
Open CircuitGenerated by open-circuits on either monitored loop relays or modules.
Board ResetA Pertronic Loop Responder has restarted.
Supply DefectThere is either a 'Defect' in the detector supply on a Loop Responder, or the external power supply on a Pertronic Loop Relay board is out of range.
Isolator ActiveThe on-board isolator relay on a Pertronic Loop Responder or Relay has activated due to a short-circuit on the loop.

Manual OFF A SW3 device has been switched off.
Manual ON A SW3 device has been switched on.

Network Messages

This table provides descriptions for network messages.
These are messages reported to the F220 from a connected network and are logged by the F220.  Each message will be prefixed by a network node number apart from the  " SYSTEM OFFLINE" message.

Message Description
Network Service Mode
The network the F220 is connected to has been put into Service Mode.
Network Service Mode is used for updating configurations for all nodes and all panels across the network from a single location.
In network service mode, the network does not transfer normal operational information from panels so therefore no normal network functions are available. Each panel in the network will remain in service and operate independently, but the panels will not be able to send fire indications or fault indications over the network.
F220 panels and mimics treat Network Service Mode as a System Event. Normal keyboard and display functions remain available (by pressing the keyboard buttons such as ok or menu).
Node X Node Config Mismatch FaultThe connected network card configuration does not match that stored by the other network cards.
This fault will be reported identically on all panels within the scope of the connected network card. The fault location will identify the network card (node) with the configuration mismatch.
Node X Panel Config Mismatch FaultThe panel configuration does not match that stored by the connected network card.
This fault will be reported identically on all panels within the scope of the connected network card. The fault location will identify the panel with the configuration mismatch.
Node X Timeout FaultNetwork Card X is not responding
Node X Earth FaultNetwork Card X has detected an earth fault condition.
Node X Net In TImeout FaultNetwork Card X has reported the loss of network data at the IN connection
Node X Net Out TImeout FaultNetwork Card X has reported the loss of network data at the OUT connection
Node X Panel Comms ErrorsNetwork Card X has communications errors with its connected panel
Node X UBoot CRC FaultNetwork Card X has detected a critical file which has been corrupted
Node X Aux Fault I/P FaultNetwork Card X has an active Aux Fault input
Node X Timezone Mismatch FaultThere are differences between panels configured timezone settings
Node X Net Disabled FaultNetwork Card X is connected to a panel which has not had networking enabled in its configuration

Power Supply Fault Indication Table

Possible causes of F220 power supply faults are

FaultLCD Message
CommentsController Code (Local 7 segment display)Fault Relay
Standalone ModePanel Mode
Mains LostMains Supply FaultOccurs when input DC supply is less than 19.8 V. Clears when supply voltage is greater than 20.8 V and is stable for at least 1 second. '1'YN
Supply Low VoltageCharger LowOccurs when input DC supply falls below 25.2 V. Clears when supply voltage is 26.2 V or higher continuously for at least 1 second. '2'YN
Supply High VoltageCharger HighOccurs when input DC supply is greater than 29.5 V. Clears when supply voltage falls below 28.5 V. '3'YN
Battery MissingBattery Disconnected

Occurs when battery connected is less than 19 V or battery voltage falls below 19 V. Cleared when battery voltage is equal to 20V or higher.
The first battery presence check is performed 15 seconds after boot up (giving the user sufficient time to connect the batteries) and subsequent battery presence checks are undertaken once every minute.
Battery missing fault will be cleared within 10 seconds once the battery is connected or the battery voltage is greater than 20 Volts.

Fault codes 'b' and '6' look similar. 
See images below to help distinguish the correct character.

          b                      six

'b' YN
Battery LowBattery LowIn normal operation, a battery low fault occurs when the mains supply is missing and battery voltage is between 20V and 22V. The fault is cleared when the battery voltage is 23 V or higher.
During autotest (in both panel and standalone modes), a battery low fault will be indicated when the voltage drops below a threshold range of 19V and 0.9 x float voltage. When the battery voltage goes below 0.9 x float voltage, the auto test will be aborted and the battery low fault will be latched.
'L' YN
Charger FaultCharger FaultIn normal conditions, this fault occurs when charger voltage is below (0.9 x float voltage) or greater than 29.5V with mains supply present, where float voltage is based on current battery temperature.
Charger fault clears when charger voltage is greater than (0.9 x float voltage) + 1V (AS7240.4 - 5.4d).
In boost charge mode, this fault is indicated only when the charger voltage is greater than 29.5volts.
External Temperature Sensor MissingTemp Sensor

Occurs when there is a read error from external/internal temperature sensor. It is not limited to only the external temp sensor. It can also occur when the external temperature is missing or not connected.

Fault codes 'b' and '6' look similar. 
See images below to help distinguish the correct character.

          b                      six

DC Out IndicationOccurs when output DC voltage is below 24.4 V or higher than 29.0 V. This state will only be indicated on the PSU's 7-segment display. It is not a fault condition and will not activate the fault relay.
Clears when output DC voltage is in the range 24.7 V – 28.7 V
Will not occur during automatic 'Battery Capacity' test.
Will not occur if the mains is missing.
Battery Charger Current HighCurrent HighOn PSU H/W version 1.x
Occurs when charger draws more than 4 Amps for 30 seconds.
Clears when current drawn is below 4 Amps for 700 mSec.
When the charger current increases more than 2 Amps for 5 seconds, the software reports a current high fault.
On PSU H/W verions 2.x
Except the threshold values across different product variants the logic to set/clear the fault remains the same. For 5A/11A variant: Charger high threshold is set to 3.5A
For 22A variant, charger threshold is set to 6.5 A
Charger Comms LostComms LostOccurs when the communications between the panel and the charger board is lost for 10 seconds. '9'N/AN
Charger Program CRC failureProgram CRCOccurs when computed CRC value is not the same as the value stored in flash memory.'C'YN
Load ShutdownOutput DC voltage is cut off when mains supply is missing and battery voltage falls below 13.5 V.
Clears when mains supply is turned on or battery voltage is .22V or greater.
Auto TestNot a fault. Just an indication on 7 segment display of charger controller. Occurs when charger controller goes for auto-test. This test is run for 40mins.
The test will automatically abort if
  • Mains is disconnected (i.e. no mains)
  • Battery is disconnected (i.e. no battery)
  • Battery discharges to 0.9*float voltage (i.e it has reached battery low threshold).
Watchdog Reset Occurs when the most recent reset of Charger Controller was due to watchdog failure'd'YN
Trickle ChargeOn PSU H/W version 2.x
Only indicated on 7-segment display and not present on 485 data output. PSU enters trickle charge mode when system current exceeds the thresholds list in Table 14‑4 ).The PSU switches back into normal charging mode when system current falls below the thresholds listed in Table 14‑4.
  1. The decimal point of the 7-segment display will toggle every half second (500ms On, 500ms Off) in Normal Charge mode and be on, steadily, when the charger is in ‘Boost Charge’ mode.
  2. In Panel Controlled mode, the fault relay will operate (de-energise) only in the case of complete PSU failure.
  3. In Standalone Mode, the fault relay will de-energise for all PSU fault except ‘DC Out’.

Detector Sensitivity Table

Provides a guide to the detector sensitivity configured and the actual level required to generate an alarm.

Detector Sensitivity Table


  1. The actual sensitivity of the Acclimate detector at levels 0 and -2 is determined by the internal algorithms of the detector itself. In “noisy” environments the actual sensitivity decreases towards the lower sensitivity in the range (higher %/m value), and in “quiet” environments the higher sensitivity (lower %/m) is used.

  2. For the intelligent detectors (Acclimate, Pinnacle & FAAST), the detector outputs a set of fixed, discrete levels for each sensitivity setting. Pre-alarm condition is determined by looking for an active level at the next-highest setting There is no Pre-Alarm warning available on the highest sensitivity level, therefore it is recommended that detectors are not ‘Brigade Calling’ at the highest sensitivity level.

  3. At the lowest sensitivity (-4), the Acclimate, COPTIR and PTIR are Heat only detectors.

  4. See FAAST sensitivity table below

COPTIR/PTIR Sensitivity Table

The table below summarises the principal properties of the COPTIR and PTIR at the 6 available sensitivity settings.

COPTIR/PTIR Sensitivity Table

FAAST Sensitivities Table

The FAAST has 5 named alarm threshold values that are locally assigned to the device via the PipeIQ configuration software as follows:
