Table 1. Menu 33 Initialisation Fault Reports for IDIS

Fault report Meaning

Loop xx overcurrent 1. A module tamper loop shorted to 0V (N/A

to LIMs).

2. A short between 0V and bus signal.

3. +12V and bus signal crossed at one or

more sensors.

All zones on a loop missing. 1. A module tamper shorted to +12V (N/A to

LIMs).

2. Broken wiring.

3. Excess capacitance on IDIS bus.

Duplicate module 1. One or more modules have the same ID.

2. A module alarm loop shorted to bus (N/A

to LIMs).

Note:

1. Use Menu 33 Initialisation to re-initialise the IDIS loops every time you

change the wiring. This is the only way to recover any modules that the system

reports as missing.

2. Make sure that the panel is in IDIS programming mode (Menu 22) when

connecting or disconnecting IDIS bus wires. This ensures that the bus signal is

static at 0V and avoids the (very remote) possibility of accidentally reprogram-

ming any of the modules attached to the IDIS bus.

If you have a fault that is intermittent, or cannot be traced

easily, then always prove the main equipment first by changing

it before starting extensive fault finding.

Simple Test Method

1. Try replacing the module or LIM with another, programmed to the same

address. If the fault remains then there may be a problem with the

wiring.

2. Disconnect the module or LIM from the IDIS bus and connect it either

directly to the panel or to the Handheld Programmer:

a) If connected to the panel then initialise the module using Menu 33,

see Table 1 for a list of possible fault reports. Ignore any mes-

sages about missing modules other than the one you are testing.

b) Run diagnostic checks on the module. Table 2 shows a list of

possible fault reports from Menu 04. Table 3 shows a list of possi-

ble fault reports from the Handheld Programmer.
