Field reference for fire alarm and life safety technicians. 11 entries, taken from the LoopWatt app.
Reference notes from LoopWatt, the offline field toolkit for fire alarm and life safety technicians. It works with no cell signal, because the sites do not have any.
Get LoopWatt on the App StoreDevice troubles report by loop and address with a point label
Invalid reply usually means a device answered incorrectly: check for duplicate addresses or a swapped device type
Charger and ground fault troubles are panel level events on the system trouble list
Read status to view points without changing anything
History buffer holds events; walk test enabled per loop or zone
Program changes need the panel password and often VeriFire Tools on a laptop
NFS and NFW series addressable panels; ONYX line. FlashScan and CLIP polling protocols.
TrueAlarm sensors report almost dirty and dirty service conditions before nuisance level
Card level troubles (loop card, NAC card) list separately from point troubles
Ground faults isolate per power supply or loop card on larger systems, which helps localization
Front panel access levels gate functions; level 3 and up changes state
System reports menu prints sensitivity reports that satisfy the sensitivity test requirement
Walk test by group with or without notification
4007ES, 4010ES, 4100ES addressable platforms; IDNet and MAPNET device protocols; TrueAlarm analog sensing.
Signature devices self diagnose; dirty and internal fault states report per device
Map faults occur when the wired layout no longer matches the learned circuit map: look for added, removed, or rewired devices
Riser and audio troubles separate from point troubles on voice systems
Program and status via the SDU or panel front; mapping is a distinctive EST concept
Test fire groups support walk test
History and status accessible without password; changes gated
EST3, EST4, iO series; Signature series intelligent devices.
Loop troubles report by SLC and point; JumpStart auto programming can mask address mistakes, verify point labels
Ground fault indicated at the main board; isolate by unplugging field circuits
Front panel programming possible on many models without a laptop
Walk test and fire drill from the test menu
History under the event menu
6000 and IFP series addressable; SK and SD device protocols; part of Honeywell.
Addressable troubles list address and type mismatch separately: type mismatch means the wrong device model answered at that address
NAC troubles per circuit; check the EOL value first (4.7k typical)
Front panel programming on most models
Read status shows detector chamber values on addressable heads
Walk test silent or audible from the test menu
MS series conventional, ES and MS addressable (LiteSpeed protocol); Honeywell family, shares concepts with Notifier.
Identify the actual sub brand and model first; concepts follow the sub brand's line
Shared device protocols exist across sub brands but devices are usually brand locked
See the specific sub brand entry
Parent of Notifier, Silent Knight, Fire Lite, Gamewell FCI; also Vista and commercial combo panels.
Device events carry a detailed fault reason (no answer, wrong type, contamination level)
ASA detectors report application specific sensitivity states; contamination reporting is built in
Person machine interface with access levels; commissioning via Zeus or Cerberus tools
Walk test per zone; event memory extensive
Cerberus PRO and Desigo Fire (FC and FV series), legacy MXL and XLS; FDnet and HNET device buses.
EOL 5.1k on many circuits, different from the 4.7k many techs assume
SLC troubles report per point; check polarity on retrofits, some devices are polarity sensitive
Front panel menus with USB programming on newer models
Walk test and one person test modes
PFC and IPA addressable series; AFC conventional; also known for sprinkler supervision products.
E3 networks distribute intelligence; a network trouble can mimic many point troubles, check network nodes first
Velociti devices share behavior with Notifier FlashScan generation
Network configuration via CAMWorks; local read status at each node
History per node and network wide
E3 Series, 7100 legacy; S3 Series; Honeywell family, Velociti and CLIP protocols.
Dual language displays common; troubles list per loop and address
EOL 3.9k typical; verify per model
Front panel walk test; configurator software for programming
Verify Canadian vs US listing differences on retrofit jobs
FX series addressable, FA conventional; common in Canada, uses AP and CLIP compatible protocols on some lines.
LSN bus faults report per segment; loop topology matters (T taps limited)
EOL values differ across product generations; check the manual before condemning a circuit
Programming via RPS or FSP software; limited front panel changes
History and diagnostics from the keypad menus
FPD and Avenar panels; D7024 and FPD 7024 legacy; LSN device bus on newer lines.
