ATS 2000/3000/4000/4500 Programming manual 167
Data gathering panels - Models ATS1201, ATS1210, ATS1211, ATS1220
Condition Possible cause
• The "Tx" LED on the data gathering panel is not
flashing.
• The dipswitches may be incorrectly set (the
address recorded on the DGP may be incorrect
and therefore polling to the DGP is not being
acknowledged).
• The system databus cable may be connected
incorrectly.
• The data gathering panel is not programmed to
be polled.
• "Tx" and "Rx" LED’s are not operating. • No power or low power.
• The system databus cable may be connected
incorrectly or the power supply is faulty (mains or
battery).
• The data gathering panel appears to be going
off-line and on-line (indicated by "DGP Fail" on a
LCD arming station).
• The termination may be incorrect. See
Installation guide - Cabling.
• Some or all DGP zones are permanently in
tamper (or permanently in alarm if "Dual zone
enabled" in System options is set to NO).
• The zone numbers for the DGP have been
calculated incorrectly, and zone type numbers
have therefore been assigned to the wrong
zones in the zone database. See the installation
guide on “zones and outputs allocated to each
DGP”.
• The End-Of-Line resistors are wrong or the
wrong resistor value is programmed in System
options (page 67).
• There is a problem with wiring the zones. To
check the voltage or resistor values, see the
control panels installation guide.
• The ATS1202 expansion module(s) (if fitted)
have the dipswitches incorrectly set.

Dipswitch 4 not used
• Two or three ATS1202 expansion modules are
fitted to increase the DGP to 24 or 32 zones, but
the 17
th
to 32
nd
zones on the DGP do not seem
to function.
• Dipswitch A on the DGP has not been set to ON.
• Four-way relay module(s) (ATS1810) being used
with the DGP do not function, but some of the
LED’s on the module appear to be permanently
on.
• Dipswitch B on the DGP is set to ON (dipswitch
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
DGP do not function.
• Dipswitch B on the DGP has not been set to ON.
