protection material gas and fire detectors can be connected to the hazardous areas. To do that hazardous
areas should be checked and the protection material need to be select according to condition of this area.
While mounting the system in a hazardous area, experienced and educated technical team should be
assigned. Panel should be placed to an easy reachable, clean and dry place without forming any vibration.
The LCD on the panel should be located in flat wall on eye level and pay attention to mount inside of any
cabinet or near to high heat emitting devices. Screws or bolts of a minimum of 4mm diameter must be used
