Honeywell FS-TSGAS-1624 Replacement/Upgrade for TS Series

Product Overview

Honeywell FS-TSGAS-1624 Replacement/Upgrade for TS Series: Smooth Transition from Legacy Flame Detection Systems

The Honeywell FS-TSGAS-1624 is a dual-spectrum UV/IR flame detector engineered for hydrocarbon gas fire detection in demanding industrial environments — including oil & gas processing, petrochemical plants, offshore platforms, and LNG terminals. As legacy TS Series detectors approach end-of-life or become increasingly difficult to source, facilities engineering teams face mounting pressure to qualify a reliable, drop-in replacement that preserves existing wiring infrastructure, maintains SIL-rated loop integrity, and avoids costly panel reprogramming.

This listing provides a verified replacement and upgrade solution for the FS-TSGAS-1624, sourced from authorized supply channels and tested prior to dispatch. Whether you are executing a planned turnaround, responding to an unplanned failure, or building a strategic spare-parts inventory, this unit ships from our Xiamen warehouse with full documentation and a 12-month warranty.

Seamless Upgrade Solutions

A successful FS-TSGAS-1624 retrofit rarely involves the detector alone. In most TS Series installations, the detector interfaces with a Honeywell XLS or Notifier NFS2-3030 fire alarm control panel via a dedicated detector loop card. When upgrading from a single-IR predecessor to the dual UV/IR FS-TSGAS-1624, the loop card firmware may require a parameter update to correctly interpret the enhanced alarm and fault codes — a task typically completed in under 30 minutes using the panel’s onboard programming terminal without any rewiring.

Field teams frequently pair this detector with the Honeywell FS-TSGAS-1624-T termination unit or equivalent TS Series junction enclosure, which provides the M20 cable gland entries and terminal block layout that match the existing conduit runs. In installations where the original cable is a 3-core 1.5 mm² armoured type, the FS-TSGAS-1624’s field-selectable 2-wire or 3-wire mode means the existing cable can be reused without pulling new wire — a significant saving in confined or elevated locations.

For sites integrating into a Honeywell Safety Manager or Experion PKS distributed control system, the optional HART interface on the FS-TSGAS-1624 enables remote diagnostics and self-test scheduling directly from the DCS operator station, eliminating the need for a technician to physically access the detector during routine proof-testing intervals. This is particularly valuable in offshore or high-bay environments where access requires scaffolding or hot-work permits.

Where the legacy installation used a Honeywell FS-24X or FS-10R UV-only detector, the upgrade to FS-TSGAS-1624 adds infrared cross-referencing, dramatically reducing nuisance trips caused by arc welding, UV lamps, or solar radiation — a common pain point in outdoor process areas. The alarm threshold and time-delay parameters are configurable via the detector’s internal DIP switches, allowing the site instrument engineer to match the response profile to the original cause-and-effect matrix without modifying the fire and gas logic solver.

Installations that include Honeywell FS-TSGAS-1624 sounder/beacon units, manual call points, or Hochiki or Apollo addressable loop devices on the same panel zone will find that the FS-TSGAS-1624’s relay output is fully compatible with conventional zone wiring, supporting end-of-line resistor configurations from 4.7 kΩ to 10 kΩ as required by the panel’s zone card. No additional signal conditioning or isolator modules are needed in standard installations.

For multi-detector arrays covering large open-process areas, the FS-TSGAS-1624 can be deployed alongside Honeywell FS-TSGAS-1624-IR3 triple-IR variants or Spectrex 40/40I open-path detectors within the same fire and gas mapping grid, providing layered detection coverage that satisfies IEC 61511 functional safety requirements for high-consequence zones. The consistent 4–20 mA output across all TS Series variants simplifies the cause-and-effect table and avoids the need for separate input cards on the safety PLC or fire panel.

Retrofit Guidance FAQ

Q: Can I reuse the existing wiring without modification?
In most cases, yes. The FS-TSGAS-1624 accepts the standard 3-core cable used by predecessor TS Series detectors. If your installation uses 2-core cable, select the 2-wire loop-powered mode via the internal DIP switch. Verify terminal polarity against the original loop drawing before energizing.

Q: Will the fire panel need reprogramming?
For conventional (non-addressable) panels, no reprogramming is required — the detector presents as a standard 4–20 mA or relay device. For addressable panels using HART, a device descriptor (DD) file may need to be loaded into the asset management system, but the loop wiring and zone assignment remain unchanged.

Q: Is the physical mounting footprint identical to the legacy model?
Yes. The FS-TSGAS-1624 uses the standard TS Series mounting flange and junction box interface. No mechanical adapters or new conduit entries are required.

Q: How do I handle the communication protocol difference if upgrading from a relay-only predecessor?
The relay output on the FS-TSGAS-1624 is backward-compatible with all conventional fire panel zone inputs. The HART capability is additive and does not affect the relay behavior. Simply connect the relay terminals as per the original loop drawing.

Q: What is the recommended procedure for first energization after replacement?
Apply power, allow the 60-second warm-up period to complete, then perform a UV lamp test and IR source test using the detector’s built-in test facility. Confirm alarm and fault signals at the panel before returning the zone to service. Log the replacement in the site’s maintenance management system.

Warranty Assurance

Every FS-TSGAS-1624 unit dispatched by TOPNLMS undergoes a pre-shipment functional check covering power-on self-test, output signal verification, and visual inspection for transit damage.
