The supply will also need to be able to support the required number of connected gas sensors. For a fully loaded system of 20 sensors, this would need to be around 35W. © 2011 Gastech Australia Pty Ltd Page 10... -

5A maximum. If the relays are being used to switch inductive loads such as contactors, motors or lamps directly, the contacts are rated 20WDC/100WAC maximum. If in doubt, please contact GasTech Australia. © 2011 Gastech Australia Pty Ltd Page 12... -
Page 15: System Operation
This is due to the initial warm-up characteristics of the carbon monoxide sensors. The GasTech 'C-Guard' has a 60 second warm-up timer that holds the output signal at 4mA to allow the sensor to stabilise. If sensors have been stored for a long time or stored in extremes of temperature, the settling time of the sensors may be longer than the 60 seconds, resulting in a period where the signals into the controller are seen as measured gas concentrations. -
Page 16: Fan Control / Alarm Relays
The control voltage is set based on the highest input signal fed from any of the enabled channels. For a gas sensor this represents the unit that is sensing the highest concentration level. © 2011 Gastech Australia Pty Ltd Page 14... -
