Issue Description

From the NetEcol, we found there is an Alarm of Skylight. Hence , we try to check on the IDS2000 room and found that one of the skylight is opening there.

Alarm Information

Skylight Ceiling Controller Output Status   24   Open

Handling Process

1.) Use Multi Meter to measure the Port on the Sky Light Controller which is connected to Sky Light. It should be 12V. There should be 4 Connection to the Sky Light ( 4 Unit ). If you found 1 of the Connection did not give output of 12 Volt, you can change it to others port. Positive or negative connection doesn’t matter for this connection. Any Group or any Port also doesn’t not matter for the connection.

2.) Measurement of the Cable on the Sky Light before it connected to the Magnetic Controller.It should give 12V output also. If it doesn’t, we will check the cabling if there is any broken / break in between.

3.) If the Voltage is Normal from the Skylight Controller which give 12Volt output, We will take a measurement on the Magnetic Controller.The measurement should be around 160 ohm.

4.) The Switch should be NC by default.

5.) After the Skylight window is working, we can press the Red Button on the skylight controller for testing as it will be Open. Once we release the button, the Skylight Window will be closed.
