Normally Closed (NC) Loops
To enable normally closed loops, Section [013], Option [1] must
be ON.
Note:
This option should only be selected if Normally Closed
(NC) detection devices or contacts are being used.
Single End Of Line (EOL) Resistors (5600
)
To enable panel detection of single end of line resistors, Section
[013], Options [1] and [2] must be OFF.
Note:
This option should be selected if either Normally Closed (NC)
or Normally Open (NO) detection devices or contacts are being
used.
Double End of Line (DEOL) Resistors
Double End of Line resistors allow the panel to determine if the
zone is in alarm, tampered or faulted.
To enable panel detection of double end of line resistors, Section
[013], Option [1] must be OFF and Option [2] must be ON.
Note:
If the Double EOL supervision option is enabled, all hard-
wire zones on the main panel must be wired for Double EOL
resistors, except for Fire, CO and 24-hr Supervisory zones.
Note:
Do not use DEOL resistors for Fire zones, CO zones or
24-hr Supervisory zones. Do not wire Fire zones to keypad zone
terminals if the DEOL supervision option is selected.
Note:
This option can only be selected if Normally Closed (NC)
detection devices or contacts are being used.

2.10 Zone Doubling
Zone Doubling is a feature that will allow you to double the
zones on the main board from 4 to 8. To enable zone doubling,
Section 13 Option [7] must be ON. All zones must be wired
according to the following diagram. Only Normally Closed
devices can be used with zone doubling.
Note:
All resistors are 5% tolerance.
The loop using the 1500
and
5600
resistors is the first zone
(Zone 1, 2, 3, or 4). The loop using the 1500
and
2400
resistors is the second zone (Zone 5, 6, 7, or 8). For example,
loop 1 is Zone 1 and loop 2 is Zone 5. The following table shows
zone status under certain conditions:
Note:
The following will be seen by the installer if the end-of-
line resistors have not been installed correctly, when both zones
are physically closed:
Note:
If zone doubling is enabled, fire zones should not be pro-
grammed. 2-wire smoke loops can still be used.
Note:
If zone doubling is enabled, keypad zones should not be
programmed.
Note:
If fire zone types are programmed in Section [001], or if a
keypad zone has been assigned, it will not be possible to enable
the zone doubling option in Section [013].
