Common Applications
Product Precautions
T3419 interfaces sixteen fire detector circuits to the Regent safety system and automatically tests their monitored wiring. Its regulated loop supply, end-of-line values and reset behavior must match the installed detector design.
- Supervises sixteen fire detector input loops
- Performs automatic loop testing and line monitoring
- Provides regulated power for the connected detector circuits
- Supports redundant detector arrangements for critical inputs
Each detector loop returns through the chassis terminal blocks to the field supply return, with external barriers where intrinsic safety is required. Commissioning includes loop-current checks, alarm simulation, wiring-fault tests, reset timing and verification of application annunciation.
Important Notice: Confirm T3419 identity, Regent chassis slot, detector types, terminal map, 15 to 40 Vdc field supply, 3.0 kohm end-of-line components, barriers, grounding, reset timing, application alarm mapping and complete loop proof test before commissioning.

Plant fire-zone detection
Interfaces monitored detector circuits to the Regent safety application.
Combustible-area alarm loops
Supervises detector alarm and wiring conditions in engineered fire-protection zones.
Redundant detector voting
Supports paired sensor and module arrangements used to maintain detection during a controlled fault.
Intrinsic-safety detector circuits
Works with an approved external barrier when the installation requires intrinsically safe field wiring.
Read the applicable ICS Triplex installation instructions before work. Verify T3419, the installed host system and all configured field interfaces before isolation, wiring or commissioning.
1
Confirm T3419 and the assigned sixteen detector-loop identities.
2
Disable affected fire functions only under the approved impairment procedure.
3
Isolate field power and record every terminal and end-of-line component.
4
Verify detector compatibility with the regulated loop and current behavior.
5
Use the approved external barrier where intrinsic safety is required.
6
Check open and short protection before reconnecting field circuits.
7
Simulate alarm, wiring fault and programmable reset on every affected loop.
8
Restore fire-system annunciation and document the completed functional test.
Technical notes
Install T3419 in the documented Regent I/O chassis slot and connect detector loops through the associated terminal blocks with the correct end-of-line components. After replacement, test alarm, open-circuit, short-circuit and programmable reset behavior for all affected loops.
FAQ View All FAQ
-
What is the exact system role of T3419?It is the 16-loop Regent input module for monitored, automatically tested fire detector circuits.
-
Which host, rack or carrier is required for T3419?Use the engineered Regent I/O chassis slot and the terminal blocks assigned to that detector group.
-
What wiring or connector checks apply to T3419?Confirm detector polarity, field return, end-of-line component, shield and any external intrinsic-safety barrier.
-
How is T3419 configured for service?Map each detector alarm, line fault and reset control to the approved Regent application and preserve the programmed reset time.
-
Which diagnostics should be reviewed for T3419?Review alarm state, open and short circuit conditions, automatic test results, reset operation and module health.
-
What must be preserved when replacing T3419?Preserve fire-zone mapping, detector type, end-of-line value, barrier data, terminal wiring and impairment records.
-
How should T3419 be commissioned after installation?Restore field power, simulate alarm and wiring faults, exercise reset and verify all control-room annunciation.
-
What model-specific limitation must be checked for T3419?Do not treat T3419 as a generic 24 V digital input; its detector-loop regulation and supervision are model-specific.
