Honeywell Meshguard

Honeywell Meshguard is designed for short- to medium-term area monitoring where speed of deployment, flexibility and coverage take priority over permanent infrastructure. Each compact, lightweight detector operates fully wirelessly from internal or external battery power, avoiding trenching, cabling and complex engineering work. Detectors can be positioned quickly around process units, tank farms, confined space entries and maintenance work zones, then removed and redeployed as projects move or shutdowns progress.

The system is particularly suited to plant turnarounds, drilling and production activities, marine and shipyard operations, tank farm work and other mobile or remote applications where conventional fixed gas detection is impractical or uneconomic.

An IEEE 802.15.4 self-forming, self-healing mesh network underpins the MeshGuard platform. Operating in the 2.4 GHz ISM band with 64-bit encryption, detectors automatically join the network and route data via the most reliable wireless path. This auto-network forming capability removes complex RF configuration and helps maintain communication even when equipment or structures move or are added.

Long line-of-sight wireless range between devices supports multi-hop networking, extending coverage over wide areas for perimeter or distributed grid monitoring. Mesh routers, remote EchoView displays and stainless steel accessories further enhance reach and visibility in congested or multi-level facilities, helping maintain a clear overview of site conditions.

MeshGuard detectors use stainless steel housing and components for high durability and corrosion resistance in harsh industrial and offshore settings. IP65 ingress protection guards against dust and water jets, while an integrated splash guard and optional rain guard help shield sensors in wet or exposed outdoor locations. Intrinsically safe design with hazardous-area approvals supports use in classified zones where flammable gases, vapours or combustible dusts may be present.

Key sensors operate across a wide temperature and humidity range, supporting deployment from cold, dry climates to hot, humid sites. Dedicated stainless steel MeshGuard versions are available for particularly corrosive or offshore environments, providing a consistent platform across diverse site conditions.

Battery power gives MeshGuard its deployment agility and helps minimise maintenance overhead. Each detector can run on an internal disposable lithium D-cell, with optional external rechargeable PowerPaks to extend runtime for toxic, oxygen and combustible gas channels. Where round-the-clock operation is essential, an optional SolarPak kit supports 24/7 autonomous monitoring, reducing battery change intervals and technician call-outs.

This combination of internal, external and solar power options allows runtimes to be tailored to project duration and risk level, without adding temporary mains supplies or extra cabling that can complicate worksite logistics.

MeshGuard supports a broad portfolio of electrochemical and infrared sensors for toxic, oxygen and combustible gas monitoring, enabling configuration for common hazards such as hydrogen sulphide, carbon monoxide, carbon dioxide, oxygen deficiency and flammables, as well as other specialised gases. Sensors are designed to deliver fine resolution and fast response times, helping detect changing gas conditions promptly for earlier intervention.

Field-replaceable sensors and consumables minimise downtime and simplify maintenance in remote or temporary locations. A straightforward two-point field calibration process, accessed via a three-key keypad and local display, supports quick onsite adjustment by a single technician. Combined with long runtime options, this helps reduce service windows and overall lifecycle costs.

In the field, MeshGuard provides clear local indication of hazardous conditions. Bright dual red LED indicators and a loud audible alarm are designed to be highly visible and audible in busy industrial environments, while an optional vibrating alarm offers an additional notification channel in high-noise areas. Bright red flashing alarms help draw attention from a distance during emergency conditions.

The large, customised LCD with backlight continuously presents real-time gas readings, alarm status, wireless link quality and battery information. User-adjustable high and low alarm thresholds, plus STEL and TWA functions in portable mode, support compliance with site safety policies and exposure limits.

Beyond individual detectors, Honeywell Meshguard scales into a site-wide area monitoring solution. Controllers such as the FMC-2000 and Touchpoint Plus Wireless can each support multiple MeshGuard detectors, providing a central point for alarm management and interface to wider safety systems. Integration with ProRAE Guardian software enables real-time viewing, logging and management of large instrument fleets over PC or Ethernet networks, with the capability to oversee hundreds of devices across a facility.

Centralised dashboards give safety teams a coherent view of distributed gas data, supporting faster incident response and better-informed decisions. Support for remote relay units and alarm devices, including RAEPoint units with alarm bars, extends alerts to beacons, sirens and control logic to align with existing emergency systems.

MeshGuard is available in Compliance Kits and Extension Kits that bundle detectors, controllers, mounting hardware, filters, calibration caps and other essential components for typical applications such as hydrogen sulphide, carbon monoxide and flammable gas monitoring. Rugged transport cases with pre-cut foam help protect equipment in transit and simplify redeployment between sites, with space for multiple detectors and a controller.

A wide range of approved accessories, including PowerPaks, SolarPaks, antennas, mounting boards, stainless steel brackets, pole mounts and strong magnetic mounts, allows a single detector platform to be adapted to many locations without custom fabrication. Readily available consumables and spares, such as filters, O-rings, covers, batteries and antennas, support long-term ownership and consistent performance across the lifecycle of temporary and semi-permanent monitoring campaigns.
