In the event of a fire in a building or other structure, such as an oil rig, Health and Safety regulations require that immediate action be taken to prevent the ingress of smoke and fume into air-conditioning and ventilation ducts. The Model 125 explosion-proof smoke monitor is specifically designed to be mounted in ventilation ducts and to comply with strict regulations that require rapid activation of smoke-damping equipment to minimise risk to human life. The equipment is constructed and tested to EExd IIB T5 standards enabling it to operate in hazardous areas..
