Base camps and other forward deployed operating bases are highly vulnerable to both conventional and asymmetric/terrorist attacks. The frequency of attacks against Allied Forces during Operations Enduring Freedom and Iraqi Freedom indicate that current and future force deployments face an increased probability of such attacks.
The high casualty rates and disruption to operations emphasize the need for enhanced protection of deployed Allied Forces and other peace keeping operations. Conventional security measures provide little or no protection from improvised lethal attacks. Previous attacks have exposed various weak points and shortcomings in current systems of Camp Protection.
Sensor Platform X (WSB2-X) is a module based software platform for sensor integration, data analysis, alert detection and alert response handling. It provides an automated surveillance system that monitors different kinds of sensors, performs sensor analysis and notifies and aids users in response to critical situations. WSB2-X is a unified management platform providing the customer with a customizable and easy scalable solution to collect physical security sub-systems into one easy-to-manage system.
Its ability to integrate and manage third-party systems suits the needs of Military Camp Operations by consolidating information from various sources and presenting it in a way that is clear and draws an operator’s attention to the most critical information.
Our main focus areas are listed below, but through our partners we can expand the delivery to fit the customer’s requirements Our strategic partners (Australia, Germany) deliver products, systems and services such as:

What are the mounting heights for CO gas detectors?
Carbon Monoxide (CO) gas has a slightly lower density than air. Recommended mounting height for Carbon Monoxide (CO) gas detector is 1.5 m above the floor.
According in garages are concentrations expected less 1%VOL and because of thermal an convection of gas the spreading is at whole area.
CO Gas Sensor
How many CO gas detectors are needed in a stationary installation?
There may exist some consultants, some local regulations or some country regulations, however, there are no absolute rules in determining the number of gas detectors and gas detectors location. (EN50545 CO 400m²).
The number of gas detectors are to be decided from case to case depending on the situation of the location you want to detect and monitor.
There are recommendations-guidelines (rule of thumbs).
One gas detector per 400 m2 (Coverage Area: 465 m2 to 930 m2 “Ideal Conditions” assumed using New Gas-DO-300-D) (i.e. one CO gas detector per 400 m2), plus additional gas detectors at the locations where gas leakage is likely to occur, preferably no farther than 1.5 meter (Mount at a height of 1.5 – 1.8 m above floor) where gas leakage is likely to occur.
What are the measuring ppm ranges for pre-alarm and warning alarm for CO gas detectors?
CO detectors alarm levels:
Pre-alarm: 25 ppm.
Warning alarm: 35 ppm.
Fire alarm: 200 ppm
Measuring Range:0-300 ppm, Model no:GAS-CO-300-D
What is the gas sensor (cell) life time for CO gas detectors?
CO gas sensor (cell) life expectancy is 6-10 years, normal operation environment.
Fully sealed sensor cell, Gel type electrolyte not liquid type electrolyte with hydrophobic filter
If gas sensor (cell) is intensively exposed for fumes (gas) the life time is shorter.
If gas sensor (cell) is less exposed for fumes (gas) the life time can be longer.
Gas Sensor With Display Version
Are the gas detectors needed to be re-calibrated?
The CO gas detectors are pre-calibrated before delivery.
The CO gas detectors are recommended to be re-calibrated on site or in-house once a year.
What to do when life time of gas sensor (cell) exceeded the expected life time ?
There are some different alternative choices, for examples:
New gas sensor (cell) can be ordered with re-calibration of the new gas sensor (cell) on existing PCB on site. For this alternative, the re-calibration instructions are needed to be followed very carefully. Recommended to be done of trained technicians.
Existing PCB can be returned to ALVI Group OR MSR and new sensor (cell) can be ordered.
The existing PCB can be factory pre-calibrated with the new sensor (cell).
New factory pre-calibrated gas sensor (cell) and PCB can be ordered.
Then the installer easily replace the existing gas sensor (cell) and PCB with the new factory pre-calibrated gas sensor (cell) and pcb. This is the easiest way of all above examples.
The exchangeable sensor transmitter cartridge is our new concept to re-look on the Gas sensor and we are pleased to introduce Our most popular, most miniaturized exchangeable Carbon Monoxide (CO) sensor cartridge with cutting edge German Technology.
