1.1.2 Loop Card Faults
Description:
If the Loop card (MAPNET or IDNET) is in an ABNORMAL (FAULT) state, all devices on that loop will be
displayed as NORMAL.
This NORMAL indication is used to reduce the number of faults when a Loop is not working as all devices
would be displayed as NO ANSWER.
To confirm a Loop card is in NORMAL status:

Press the MENU button.

Scroll through the options until CARD STATUS is reached.

Press the ENTER button

Scroll through the cards in the panel. Confirm that each loop card is NORMAL.

If CARD MISSING FAILED ABNORMAL then press ENTER and Scroll through card faults.

Refer to the relevant section for fault descriptions.

IDNet Loop Voltage = approx24vDC normally & 30vDC when the panel is in alarm

MAPNet Loop Voltage = approx 36vDC at all times.
Note: IDNet & MAPNet Loop Voltages are fluctuating DC because the Loop Voltage is modulated
to transmit the data.
NOTE - It is vital that the Loop card is in
NORMAL status before addressable
device fault finding is started.
