Gas detection for car parks, swimming pools, schools, concert halls, theatres, etc.

Analogue or CAN Bus control unit

DALEMANS offers two types of control units. The analogue system offers star-shaped detector wiring. The CAN Bus system has inline cabling. In addition, it can also be equipped with a DMS remote display system. 

In the event of a pre-alarm, the ventilation is activated at low speed. In the event of an alarm, the ventilation is switched over to high speed. If the concentration level increases again, the light panels and sirens are activated. For schools, concert halls or theatres, flashes are activated.

Types of gas detected: CO - NO₂ - CNG - LPG - Cl₂ - O₃ - CO₂ - H₂

DALEMANS systems are designed to detect carbon monoxide, nitrogen dioxide, CNG, LPG, chlorine, ozone, carbon dioxide and hydrogen.

Position of the detectors

The position of the detectors is adapted according to the density of the gas. To detect carbon monoxide and nitrogen dioxide, the detectors are placed 150 cm from the ground. For LPG, chlorine, ozone and carbon dioxide, they are placed 15 cm above the floor. For CNG and hydrogen, the detectors are placed on the ceiling.

Start-up and maintenance

Directly, or through your fitter, DALEMANS carries out the start-up and maintenance of your gas detection system in Belgium and Luxembourg.
