Fire Detection and Alarm System
Fire detection is possible by monitoring the carbon monoxide levels or by a sudden increase in chamber temperature. Once fire is detected, an audio-visual alarm can be triggered for alerting the operator.
Fire Suppression/ Extinguishing
When a fire is detected inside the test space, it is extinguished by flooding the test space with carbon dioxide (CO2) or Nitrogen (N2).
After the completion of a test, the chamber may be intertised with nitrogen (N2) in order to flush out any hazardous or combustible gases and reduce the oxygen concentration before opening the door.
Oxygen measurement is used in conjunction with the chamber inertisation to monitor the concentrating levels and control the nitrogen flushing.
Pressure Relief Vent
A pressure relief vent is provided to equalize the pressure in the chamber during inertisation or flushing of CO2.
In the case of an explosion, there is a sudden release of gas and increase of pressure inside the chamber. A Burst disk is provided to release this pressure into an exhaust duct.
