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.
 Loop Voltage = approx 30V DC
NOTE - It is vital that the Loop card is in
NORMAL status before addressable
device fault finding is started
