The following table shows zone status under certain conditions for SEOL:
Table 8: SEOL Loop Status
Loop Resistance
Loop Status
0Ω (shorted wire, loop shorted)
Violated
5600Ω (contact closed)
Secure
Infinite (broken wire, loop open)
Violated
Double End of Line (DEOL) Resistors
When double end-of-line (DEOL) resistors are installed at the end of a zone loop, the second
resistor enables the panel to determine if the zone is in open, closed, tampered or faulted.
Note:
Any zone programmed for Fire or 24-hr Supervisory must be wired with a SEOL resistor
regardless of the type of zone wiring supervision selected for the panel. If you change the
zone supervision options from DEOL to SEOL or from NC to DEOL, power the system down
completely, then power it back up for correct operation.To enable DEOL supervision, program
section [013], option [1] to OFF and option [2] to ON.
Figure 11: DEOL Wiring
Note:
If the DEOL supervision option is enabled, all hardwired zones must be wired for DEOL
resistors, except for Fire and 24 Hour Supervisory zones. Do not use DEOL resistors for Fire
zones or 24 Hour Supervisory zones.
Note:
Do not wire Fire zones to keypad zone terminals if the DEOL supervision option is
selected.
Note:
This option can only be selected if N/C detection devices or contacts are used. Only one
N/C contact can be connected to each zone.
The following table shows zone status under certain conditions for DEOL:
