16 Gas Detection


High Performance Gas Detection Controller with Logic Control Launched


Critical Environment Technologies Canada Inc. (CETCI) is pleased to announce the release of their FCS Flexible Control System. The FCS replaces the PDC, offering dramatic technological and functional improvements over its predecessor.


The FCS Flexible Control System is a sophisticated, high performance Controller that offers up to 128 gas channel confi gurations for monitoring toxic, combustible and refrigerant gases with versatile control functionality for non-hazardous, non-explosion rated, commercial and light industrial applications. The FCS is designed to accept inputs from digital and analogue transmitters and/or Peripheral Devices (in various combinations), using Modbus®


RS-485 or 4-20 mA analogue input. In addition, the FCS is available with Modbus® communicating with a Building Automation System (BAS).


Standard features include, a full colour, LCD touch screen with LED indicators for Power, Status and Fault, a door mounted audible alarm, an extensive menu structure with password protection, a USB port for fi rmware upgrades and data downloads, four internal 5-amp, dry contact relays, two confi gurable switch inputs and two strobe/horn output drives. The built-in data logging capabilities have a large capacity memory for saving all channel readings, confi guration changes and transition data. The FCS has a maximum of 32 priorities which can be confi gured to defi ne the relationships between the channels and the relays, allowing up to. Up to three conditions can be assigned to each relay. Channels can be assigned to report their Low, Medium, High and/or Fault statuses which in turn can be confi gured to trigger one re more relays to act on one or more of those statuses and channels. The logic control and fl exibility of the priority levels is immense, allowing numerous monitoring and alarming confi gurations.


Optional, value added features include, internal analogue inputs (AI) and/or analogue outputs (AO), a top mounted strobe and a locking door. The FCS, like our new suite of products, uses our signature black enclosure that is IP54 rated when the optional water tight buzzer is installed at time of order.


Depending on the type and size of the application, the FCS may require additional devices to create the complete system. For networks that extend over a large area there is the potential for data noise and a reduction in the signal. The LNK-XT Network Extender is a signal booster that extends the range of the Modbus communications. An LNK-XT is recommended every 610m (2000ft) and up to 6 of these devices can be used on one FCS network. For very large system application and/or very long wire runs, the Remote Power Supply is available to boost the voltage and provide a renewed amount of power to compensate for voltage drops. The RPS-24VDC converts 90-240 VAC power to 24 VDC power. If more than the four internal relays are needed, two remote devices are available - the RLY-4 which offers four contacts and the RLY-8 that offers eight. All relays are rated at 5 amps. A maximum of 56 relays can be accommodated by the FCS. In the event that the optional internal analog inputs and/or analogue outputs are insuffi cient, there two peripheral devices, the LNK-AI and the LNK-AO available. The LNK-AI offers 4 analogue inputs and the LNK-AO offers 4 analogue outputs. Depending on the internal AI and AO confi gurations, up to a maximum of 14 LNK-AO and 14 LNK-AI devices can be connected to the FCS.


The FCS is ideal for use in large, enclosed parking facilities, indoor recreation facilities, food processing plants, refrigeration plants, chemical storage rooms, manufacturing plants and many more. For More Info, email:

The Dräger Regard 7000 is a state of the art modular control system for monitoring various gases and vapours. Its fl exible expandability ensures long term viability for gas detection systems of increasing complexity. In addition, it is backward compatible with previous Regard systems.


Dräger designed the Regard 7000 for a wide range of applications and confi gurations. It processes analog transmitter input signals supporting remote access via HART (Highway Addressable Remote Transducer) in the near future. HART simplifi es installation, confi guration, maintenance, and documentation of the gas detection system. A Modbus RTU output is available for retransmitting gas detection data to higher- level systems. The most demanding alarm logic sequences can easily be programmed, such as delays for process optimisation.

The system architecture of the Regard 7000 prevents the entire system from failing if one component fails (single point of failure). In addition, it is easy to add independent subsystems. False alarms are effectively reduced by optimised signal conditioning fi lters, manual alarm suppression, and the automatic comparison of analog and digital transmissions. Special analogue transmitter signals such as errors or warnings are indicated as text messages, making them easy for anyone to identify. A simple, easy to read menu layout with user-friendly icons simplifi es operation and increases your plant’s safety.
