OPERATION
First Power Up
1. 2. 3. 4.
1.
On connecting power, your gas detector Power LED will illuminate.
2.
The gas detector then enters a stabilisation phase for approximately 60 seconds – during this time the
Fault LED will flash indicating that the device is not yet ready for operation.
3.
The gas detector will then establish a Modbus data signal with the main control panel – during this
time the Fault LED will remain on.
4.
When a data signal is established with the main control panel, the Fault LED will switch off and the
detector will be in operation. Check your Parksafe panel for gas detector status.
Do not remove the gas sensor module under power!
