2.3.3.5.7.1 Alarm Input Name
Option: 16 characters maximum.
Enter the name to be associated with this Alarm Input.
2.3.3.5.7.2 Alarm Type
Options: Normally Open (N/O), Normally Closed (N/C), N/O SEOL, N/C SEOL, N/O DEOL, N/C DEOL
Default: Normally Open
The ADPRO FastTrace can be programmed to trigger an alarm when the contacts associated with a channel change
state. This may be when:
• a normally closed contact changes its state to open, or
• a normally open contact changes to close
The alarm inputs may be also supervised to detect tamper (attempting to override the alarm contacts by a cut or short)
with either a SEOL (Single End of Line) or a DEOL (Dual End of Line) wiring hierarchy in conjunction with N/O or
N/C sensor contacts.
Depending on the alarm wiring strategy, SEOL termination is used to detect either a short circuit on a line or on an
open circuit, while DEOL is used to detect both short and open circuit conditions.
