Fire and Gas Detection


Simtronics offer a full complement of gas and flame detection, industrial fire detection with integrated alarm and control systems.

Simtronics designs, builds, tests and commissions a range of conventional panels through to fault-tolerant, addressable networks.

Our systems capability includes MultiSafe MX, our SIL 2 or 3 approved modular multifunctional 19in rack system. MultiSafeMX is capable of conventional or addressable fire detection, gas detection, security features and fire suppression. This is complimented by the Syntel™, our industrial addressable flame and gas monitoring system. Syntel is often a key component in our detection solutions for petrochemical and chemical plants as well as nuclear and conventional power plants. Syntel has no common failure mode and a self-healing loop.

The GD1 sets a new standard for toxic gas detection. Using a tuneable laser diode the GD1 delivers enhanced coverage and fail safe detection. The performance improvement marks a genuine step change for safety systems and life cycle cost savings. At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain and fog. The laser scans single absorption lines where there is no interference from other gases. Unlike traditional methods for detecting H2S (MOS or EC cell) the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk.

iTrans 2 Fixed Gas Detector

iTrans 2 Fixed Gas Detector

Detects Explosive Gas, Toxic Gas, or Oxygen

  • Non-Intrusive Calibration
  • Smart Infrared Gas Sensors
  • HART Communication Protocol
  • MODBUS Communication
  • Programmable Relays
  • Dual Gas Sensing

Remote Diagnostics, Set-up or Calibration 

The iTrans 2 fixed gas detector employs an intelligent electronics platform to provide one or two points of detection from a single head for maximum flexibility, superior performance and lower installation costs. With the optional HART Communication Protocol, the iTrans 2 offers remote diagnostics, set-up or calibration by superimposing a high-frequency current across the industry standard 4-20mA analog line.

Smart Infrared Gas Sensor Technology and Safety Features

Able to detect any combination of gases for a specific environment, iTrans 2 utilizes our industry-proven “smart” infrared gas sensor technology and safety features including automatic sensor recognition, access code security, and zero and cal fault protection – all enclosed within an explosion-proof aluminum or stainless steel housing. The microprocessor-controlled transmitters are capable of independent operation or multi-point system configuration. The infrared sensor provides explosive gas detection (methane, butane, propane, ethylene, hexane, etc.) in more severe environmental conditions, where the presence of poisons could harm the use of a catalytic cell. In addition to the LEL sensor range, the iTrans 2 detector can also be configured with a 0-100% volume methane infrared sensor for bio-gas applications and CO2 infrared sensors ranging from 0.5% volume to 100% volume.

Stand-Alone Operation

With optional on-board relays, this fixed gas detector has the added ability of stand-alone operation, activating alarms, horns, or fans and can also shut down a system without the need to wire back to a central control panel.
