4 LED arming station - Models ATS1150 and ATS1155
Condition Possible cause
• All the LED’s on the arming station are flashing. • The dipswitches may be incorrectly set (the
address set on the arming station may be
incorrect and therefore polling to the arming
station is not being acknowledged).
• The system databus line may be connected
incorrectly.
• The arming station is not being polled (it may not
have been included in arming stations to be
polled when programming arming stations).
• LED’s do not appear to be indicating the correct
condition.
• The arming station type may have been defined
incorrectly as LCD arming station. This option
must be set to NO.
• The arming station appears to be going off-line
and on-line (indicated by the "RAS Fail"
message on a LCD arming station).
• The termination may be incorrect. See
Installation guide - Cabling.
• The arming station appears to lockup when the
relay, which it controls via the OUT terminal,
activates.
• The relay probably does not have a reverse
diode across it to protect against back emf.
• An error is indicated when a code is entered on
the keypad (seven beeps).
• An invalid PIN code may have been used.
• The arming station may not have been
programmed with an alarm group.
• The alarm group of the PIN may not permit
access at this arming station.
