Honeywell Touchpoint Plus Controller

The Honeywell Touchpoint Plus Controller is designed as the core of a fixed gas detection installation, consolidating multiple detectors, sounders, beacons and other field devices into a single control point. The base unit provides up to eight channels as standard and can be expanded to sixteen channels using an optional expansion unit, allowing facilities to match coverage to current needs and scale as operations grow. Capacity and power provisioning support use with powered gas detectors and audio-visual devices, enabling a complete loop from sensing through to alarm signalling.

A modular architecture underpins this scalability. Input, relay and communication modules can be selected to meet project requirements, while a wide range of factory-configured models provides different combinations of mA, mV and dual (mA + mV) input modules for two, four or eight channels per base. The expansion unit mirrors the base unit’s I/O capability, including support for an optional backup battery, but omits the controller and user interface, providing a cost-efficient path for channel expansion.

Touchpoint Plus accepts both 2- and 3‑wire mA and mV inputs, giving compatibility with a broad range of fixed gas detectors and related instrumentation. Optional repeated mA outputs enable retransmission of channel signals to third-party systems or additional indicators, helping engineering teams standardise monitoring across a site without duplicating infrastructure.

For higher-level integration, the controller supports selectable communication options such as Modbus RTU, Modbus TCP and web monitoring. This allows straightforward connection into SCADA systems, wider plant safety management platforms or building management systems, delivering centralised visibility of gas hazards and alarm status. Available programmable relays and dedicated audio-visual drive outputs provide direct control of beacons, sounders and actuators, reducing the need for separate interface hardware.

A 7″ colour LCD touchscreen with a graphical user interface sits at the heart of Touchpoint Plus. Real-time gas readings, alarm thresholds and system status are presented in a structured, easy-to-navigate menu, supporting rapid situational awareness during normal operation and incidents. Full-colour traffic-light style status indication (green for normal, red for alarm, yellow for fault or inhibit) provides clear at-a-glance information, while individual channel LEDs and master indicators help maintenance teams locate affected points quickly.

The multilingual touchscreen interface is designed to minimise training effort and reduce the risk of operating errors. Guided setup and logical menu sequences support fast commissioning, and clear fault and alarm labelling simplify interpretation during time-critical events. This ease of use helps reduce operator workload and supports consistent response to gas hazards across shifts.

Touchpoint Plus extends beyond live display by providing configuration, event and data logging capabilities. Historical gas readings, configuration changes and alarm or fault events can be stored and subsequently downloaded to support incident investigation, trend analysis and continuous improvement activities. This audit trail assists duty-holders in demonstrating that gas detection systems are being actively managed and maintained in line with internal procedures and external regulatory requirements.

By capturing and organising this information within the controller, engineering and HSE teams gain a single reference point for gas safety performance, simplifying preparation for audits and supporting safety case documentation.

The controller is housed in a high-impact polycarbonate ABS enclosure that provides strong mechanical protection and long-term durability. Its IP65 dust-proof and water-proof rating makes it suitable for harsh indoor and outdoor locations, including washdown and high-humidity areas. The unit is certified for use in hazardous locations, including Class I, Division 2, and is designed and approved to relevant international standards, supporting deployment in globally operated facilities.

Operating and storage temperature ranges, combined with tolerance of high humidity up to 95% RH non-condensing, help ensure reliable performance across a wide variety of climates. Compliance with multiple global safety and performance standards, including functional safety to SIL2 and applicable EN and UL/CSA standards, provides assurance for specifiers working in regulated sectors.

Touchpoint Plus is engineered to reduce installation time and complexity. The wall-mountable enclosure and optional mounting plate support quick, one-person installation using standard practices. A hinged front cover and uniquely tiered terminal arrangement provide generous wiring space and straightforward access for termination and inspection. Pre-drilled, sealed cable entries supplied with glands and blanking plugs further streamline cable management and reduce on-site fabrication work.

Each pre-assembled base unit includes the required I/O modules, an industrial-grade AC power supply for AC variants, backplate, earth terminals and cable entries, enabling rapid deployment. Predefined part numbers for common configurations simplify specification and ordering for engineering and procurement teams, and a comprehensive accessory range – including mounting brackets, cable glands, SD cards, grounding kits and adaptors – supports consistent hardware selection across multiple projects.

To support long service life and minimise downtime, key electronic modules such as the backup battery pack, I/O boards, user interface PCB, main PCB, power supply and LCD/touch module are available as spare parts. The controller is designed to help reduce nuisance alarms and simplify routine maintenance, assisting operators in maintaining productivity and avoiding unnecessary shutdowns.

On AC-powered versions, an industrial-grade 150 W power supply delivers stable power to the controller and connected field devices. An optional 22.2 V lithium-ion backup battery pack provides more than 30 minutes of typical runtime during mains interruptions, helping maintain alarm coverage and allowing orderly responses or controlled shutdowns during power loss events.

As part of the Honeywell Analytics fixed gas detection portfolio, Touchpoint Plus integrates seamlessly with Honeywell detectors, sounders and beacons to form a complete, end-to-end safety system. It is suited to applications ranging from compact plant rooms and utility areas through to larger industrial and energy facilities where a highly configurable controller is required without the overhead of a full distributed control system.

Datasheets, manuals, certificates, safety documentation and quick start guides are readily available to support design, installation and operator training. A strong manufacturer and distributor network provides installation, commissioning, calibration and servicing support, helping engineering teams maintain gas detection performance and system availability over the long term.
