Safety New Portable Detector for Flammable Gases
The µGazex developed by Gazomat™ (France) provides users with personal protection in potentially explosive atmospheres. ATEX group 1 and group 2 approved, this multifunction explosivity meter device complies with all the European safety standards.
The µGazex is available in four versions for use across a wide range of applications; Explosivity meter – 1 measurement scale : 0-100% LEL, Explosivity meter - catharometer – 2 measurement scales: 0-100% LEL et 0-100% Vol. Gas, Explosivity meter – 3 measurement scales – 0-10.000 ppm – 0-100% LEL et 0-100% Vol. Gas and Methane level meter – 1 measurement scale – 0-4.4% CH4
- for use in mines.
Very easy to use, with its single control key, the operator needs only to turn the unit on and off. He can also display the maximum values by simply pressing the control key. With the explosivity meter-catharometer version, the switching between the scales is automatic. The detector has a powerful triple alert system, offering audible, visual and vibration alarms. The fast-responding sensor is remarkable for its high stability whilst under extended exposure to gas. Ultra-light and compact in design, the detector will conveniently accompany operators in their everyday work and ensure a maximum level of safety. The Li-Ion battery provides up to 16 hours of continuous operation and greatly contributes to the light weight of the device. The double-protection elastometer housing with IP 67 protection, resistant to dust and brief immersion in water, provides greater durability to the detector for use in extremely harsh environments.
The µGazex comes in with a multi-support fastening clip, a power supply unit and a charger -conveniently; the latter can also be used to test the detector via a USB cable connected to a PC. A whole set of optional accessories are available such as a test kit, a sampling system and a multi-point charger assembly - designed for up to 10 units. The latter option will be of special interest to companies operating a large number of detectors; and, last but not least, the detector is easy to maintain.

New Multi Head Beam Detector For Wide-Area Fire Protection
Fire Fighting Enterprises (UK) has developed the technology to allow multiple Fireray 5000 optical beam smoke detector heads to operate from one single control unit. The Fireray 5000 Multi Head has up to 4 beam transceivers connected to, and managed by, one low-level system controller. This offers savings in the costs on time,
power, installation, wiring, and maintenance. Multiple detector heads mean that one system can detect smoke over an even larger area, and the heads can be positioned for total coverage of unorthodox indoor spaces.
The Fireray 5000 is already at the forefront of optical beam detection technology, with a motorised auto-aligning beam and automatic gain compensation features. During installation, the beam head will automatically adjust its aim to point directly at the reflective prism plate, with a visible laser aiding initial setup. Over time, the features will ensure that the beam stays on target and that it retains the correct signal sensitivity – counteracting against the effects of building shift, and the buildup of dust and dirt.
Each detector head can be independently configured from the single system controller to operate at a distance from 8m to 100m, with the capability for separate alarm threshold conditions (sensitivity and time) for each one. The controller then has one common set of fire and fault relays that apply to all attached heads for simplicity when communicating with a fire panel. The Multi Head Fireray 5000 has already gained worldwide approvals including LPCB, CPD, UL*.

E2S (UK) has upgraded the IP ratings of its AlertAlarm general signalling sounder range. All sizes in the family, the A105N (112dB), A112N (119dB) and A121 (126dB) sounders are now supplied sealed to IP66 as standard, enabling them to be installed with confidence even in the most demanding dusty or wet environments.
All units have 45 selectable tones and have at least two switchable alarm stages as standard; there is also the option of a fully programmable four-stage switching version, in which any available tone can be allocated to any of the four stages. Single, double, triple or quad stage alarm sequences can be selected from the tones provided. In addition to having a very realistic bell sound, the units can also mimic the traditional siren, enabling current-hungry and inherently unreliable devices to be replaced with an electronic equivalent. All models are synchronised when operated from the same control supply and are available in a choice of red and grey colours.
The latest extension to the market-leading AlertAlarm family is the SpectraAlarm range, combined sounder-beacon units that adds the new Spectra beacons to the AlertAlarm sounders in a single housing to give visual reinforcement of the audible warning. A choice of flashing xenon, rotating mirror and LED technologies are available.

The Gas Point from Recom (Italy) is an economical, microprocessor-based gas detector for continuous monitoring of toxic gases, oxygen or inflammable gases. Non intrusive calibration and maintenance is performed using a magnetic wand to access the software through the enclosure window – no need to open the enclosure (and obtain special area permits) to perform routine calibrations.
The backlight LCD graphic display shows the gas reading, with wide and visible numbers, together with the measure unit and the gas name.
In the programming mode it is possible to change the gain, the off-set, two alarm thresholds, the average, the full scale value, the sensor fail event. So, it is possible to use the same control unit with all catalytic, galvanic or electrochemical sensors. High sensitivity, long term stability and no false alarms are the hallmark of the new and improved sensors. Fastest response to the target gas combined with minimal interference buy other gases or environmental influences as well as the sensor life-time determine the reliability and the operating cost of a system. Moreover, Gas Point has an analog 4-20 mA output, for remote control or to transmit the alarm signal. Integrated control on the power supply assures the correct work also in the case of unstable voltages.

General Monitors (USA) is proud to announce the debut of its new IR4000 Multi-Point Combustible Gas Detection System Calibration Demo, which is now available online. This new 3-D web demo takes you inside a gas compressor facility, shows the appropriate placement of the system’s multiple IR400 Gas Detectors and explains how to gas check, zero and calibrate the systems multiple detectors utilizing the IR4000M Monitor.
Just under 5 minutes in length, the demo provides step-by-step instructions. The demo shows how our simple magnet interface tool can be pulled across the IR4000M Monitor to activate an LED status screen and check the status of our IR400 Detectors.
A single IR4000M Monitor connects as many as eight remote IR400 Detectors into a system configuration. The IR4000M is designed with a unique data concentrator that allows it to read the status of eight detectors with a single command. The IR4000M also can gas check and zero multiple IR400 detectors with a single command.
The IR400 detector provides an early warning when a specified concentration of combustible gas is exceeded. The IR400 is equipped with 4-20 mA analog output, HART, and Modbus, and features faster calibrations and more calibrations per gas cylinder. IR400 users can monitor gas concentration, check status and perform device diagnostics in real time.
The IR400 detector’s advanced design features heated optics to eliminate condensation and a dirty optics indicator for fail safe operation. The detector also consumes less power than its predecessor. The IR400 and IR4000 are certified to CSA, FM, ATEX, and IECEx standards and have the CE Marking.
