Page 12: Sensor Transmitter Installation
LC-Series Controller: 1-4 Channel ENMET 4.2 Sensor Transmitter Installation Mounting location for the gas detectors need to be considered individually, initial points for consideration are: Ensure all gas detectors are mounted to allow routine calibration and maintenance to be carried out as required. -
Page 13: Operation
LC-Series Controller: 1-4 Channel ENMET 5.0 Operation When a preset alarm point is reached, visual and/or audio alarms are activated. The backlit graphics display automatically displays the channel in alarm and an alarm level Led(s) are activated on the control panel. The LC-8 is factory set to maintain these alarms until they are acknowledged. - Page 14 LC-Series Controller: 1-4 Channel ENMET Connection Procedure Disconnect power from the system. Remove the terminal cover to gain access to the wiring. Remove the terminal cover and display module to gain access to the configuration link settings.
