Request Bieler+Lang gas detection equipment against your gas list, measuring points, communication architecture and project requirements.
Compare the system architecture and measurement task before choosing a family. Include the existing equipment inventory for replacement and extension work.
A compact controller for a digital two-wire BUS installation, supporting up to 32 measuring points. A display and rotary control provide local operation; Wi-Fi connection is available.
Send the detector list and existing system drawing when requesting a replacement or planning a compact installation.
GMC 8034 accepts four 4–20 mA detector inputs. It provides three alarm levels and ten configurable relay contacts, with DIN-rail mounting. Supply the input schedule and output allocation so the proposed unit can be assessed against ventilation, visual alarm and acoustic alarm requirements.
GMC 750 is a touchscreen controller for a BUS installation with up to 128 measuring points and 350 devices. ExDetector X5 and GasMonitor 750 are named detector families. For an extension, send the existing device inventory and a separate list of proposed measuring points.
HC 100 uses catalytic detection for combustible gases and vapours over 0–100% LEL, with a 4–20 mA output. HC 100 K is the duct application variant with a remote sensing head. Identify the gas, head marking and transmitter separately when requesting parts or a complete detector.
ExDetector X5 combines a two-wire digital interface with two independent 4–20 mA outputs and supports two sensing heads. Head variants cover different gases and measuring ranges. Send the complete head code and label both installed heads when requesting a replacement component.
ExDetector SC 220 and GasDetector IR-220 are separate families in the manufacturer catalogue. For an existing installation, provide the full designation from the nameplate, the gas and range from its documentation, and the connection drawing.
State whether the request concerns a complete instrument or an identified component.
SafePark addresses gas monitoring in parking facilities. The catalogue includes separate GM 750 SafePark CO, NO and NO₂ detectors, alongside GMC 650C SafePark controllers. Organise the enquiry by gas and parking area, and identify whether the project is a new system or an extension.
The accessory range includes Calibrationbox-i, FBA 2018, the SH 220 signal horn and RK 8420 expansion for GMC 8420. Match each requested item to its host instrument. Include mounting details for mechanical accessories and the existing device marking for alarm equipment.
Provide the gas, range, measuring point count, interface, power supply, installation conditions and project requirements. Include a site layout and an input/output schedule.
Send the model, serial number, full sensing head code and quantity. Label photographs with the equipment schedule reference and state the requested scope of supply.
Describe the gas to be monitored and the intended application before selecting a controller. Identify whether the installation concerns a process area, a laboratory, a duct or a parking facility. Provide the measurement range and units from the project documents.
For replacement work, use the existing instrument nameplate as the starting point. For a new installation, send the engineering specification and a schedule of measuring points. This information separates detector selection from the choice of central display and alarm equipment.
If the operating gas differs from the name on an old purchase order, highlight that discrepancy in the enquiry and include the current project documentation for technical review.
Give each measuring point a unique reference that also appears on the layout drawing. Record the gas, range, detector designation and required quantity on separate lines.
If several devices share the same enclosure, attach readable nameplate photographs so their different sensing configurations remain visible. For ExDetector X5 with two heads, identify each head separately. Distinguish complete detectors from sensing heads and other components in the purchase list.
This avoids quoting a complete assembly when the maintenance request concerns only an identified part.
The initial distinction is between analogue measuring lines and a digital BUS network. GMC 8034 has 4–20 mA inputs; GMC 635-Plus and GMC 750 belong to the digital BUS controller range. Include the existing wiring drawing and connected detector inventory in a replacement enquiry.
For a network extension, separate installed devices from proposed additions. Ask the project engineer to define the required network structure and control functions. The quotation can then address equipment quantities and accessories against a clearly stated architecture.
List the actions required by the project: visual indication, audible warning, ventilation control or transmission of status to another system. Supply the input and output allocation rather than only the number of sensors.
When replacing a central controller, include the existing relay schedule and the connected equipment designations. Identify which alarm devices are included in the purchase and which will remain on site.
Alarm thresholds and protective actions should come from the approved project and the operating documentation for the selected installation.
For a parking project, organise the enquiry by level, zone and gas. SafePark includes different GM 750 detector variants for CO, NO and NO₂; keep those names separate in the schedule. Send the central controller model and the system drawing for extensions to an existing building.
For a new installation, state which controllers, detectors and alarm accessories are included in the engineering scope. Include the receiving location and the required document package so technical review and commercial preparation use the same equipment list.
Request an accessory against its host detector or controller, with a full model designation. Mounting equipment needs installation details and useful dimensions; alarm devices need the electrical information specified in the project.
For calibration accessories, identify the sensing head and the maintenance procedure for which the item is required. Keep calibration equipment separate from replacement sensors in the enquiry.
An equipment delivery and the subsequent commissioning or maintenance operation are separate scopes, each with its own documentation and responsible personnel.
Provide a clear photograph of the entire nameplate, a close-up of the component marking and the relevant manual page or drawing. If a component code is unavailable, mark the item on a diagram and explain whether the housing and transmitter will remain in service.
Describe any displayed error and the affected measuring point without assuming which component has failed. State whether you want an identified spare, a complete replacement instrument or an assessment of the repair request. Include quantities and the intended delivery location.
Compare the proposed model, sensing head code, range, interface and included accessories with the original request. Keep engineering requirements and purchasing quantities in the same revision of the schedule.
If an installation contains several generations of equipment, identify them individually before consolidating the order. Ask the responsible project specialist to review changes to the system configuration.
This gives the purchasing team a clear record of what is being ordered and gives the installation team the documentation needed to prepare the next stage.
Attach the specification and delivery location. Stock, price, lead time, compatibility and required approvals are confirmed for the quoted configuration; no authorised dealer status is claimed. ATEX and SIL requirements are assessed using the documentation for the particular instrument.
