Advisor Advanced ATSx000A(-IP) Installation and Programming Manual
Condition
Possible cause
The expander appears to be going
off-line and on-line (indicated by
“Expander fail” on a LCD keypad)
The termination may be incorrect. See
Some or all expander zones are
permanently in tamper (or
permanently in alarm if “8.5.1 Input
mode
” on page 152 is set to Single
NO or Single NC).
The zone numbers for the expander have been calculated
incorrectly, and zone type numbers have therefore been
assigned to the wrong zones in the zone database. See
“Configuration” on page 22.
The end-of-line resistors are wrong or the wrong resistor
value is programmed in “8.5.2 EOL” (see page 152).
There is a problem with wiring the zones. To check the
voltage or resistor values, see
The ATS1202 expansion modules (if fitted) have the DIP
switches incorrectly set.

Four-way relay modules (ATS1810)
being used with the expander do
not function, but some of the LEDs
on the module appear to be
permanently on
DIP switch B on the expander is set to On (DIP switch B
should only be On if 8-way relay (ATS1811) modules or 16
open collector modules (ATS1820) are being used).
8-way relay modules (ATS1811) or
16-way open collector modules
(ATS1820) connected to the
expander do not function
DIP switch B on the expander has not been set to On.
