for the panel (section [013], options [1] and [2]). See 5.1
"Zone Definitions".
If you change the zone supervision options from DEOL to
EOL or from NC to DEOL (section [013], options [1] or [2]),
you should power down the system completely, and then
power it back up. If you do not, the zones may not work
correctly.
Normally Closed (NC) Loops
To enable normally closed loops, programming section [013],
option [1] must be ON.
NOTE: This option should only be selected if Normally
Closed (NC) devices/contacts are being used.

Single End Of Line (EOL) Resistors
To enable panel detection of single end-of-line resistors, pro-
gramming 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, pro-
gramming section [013], option [1] must be OFF and option [2]
must be ON.

NOTE:If the Double EOL supervision option is enabled, all
hardwire zones must be wired for Double EOL resistors,
except for Fire and 24 Hour Supervisory zones.
Do not wire DEOL resistors on keypad zones.
Do not use DEOL resistors for Fire zones or 24 Hour Supervi-
sory zones. Do not wire Fire zones to keypad zone termi-
nals if the DEOL supervision option is selected.
This option can only be selected if Normally Closed (NC)
detection devices or contacts are being used. Only one NC
contact can be connected to each zone.
The following chart shows zone status under certain conditions:
Loop Resistance
0Ω (shorted wire, loop shorted)
5600Ω (contact closed)
Infinite (broken wire, loop open)
11200Ω (contact open)

Fire Zone Wiring - 4-wire Smoke Detectors
All zones defined as Fire (see section 5.1 "Zone Definitions" on
page 20) must be wired according to the following diagram:
For a complete description of how fire zones operate, see section
5.1 "Zone Definitions" on page 20.
Keyswitch Zone Wiring
Zones may be programmed to be used as keyswitch arming
zones and must be wired according to the following diagram:
For a complete description of how keyswitch zones operate, see
section 5.1 "Zone Definitions" on page 20.
LINKS1000/GSM1000 Supervisory (24 Hour Supervi-
sory)
When using the LINKS1000/GSM1000 cellular communicator,
any main board zone may be configured for LINKS1000/
GSM1000 Supervision. Program this zone as zone type (09), 24
Hour Supervisory in section [001].
With a 24 Hour Supervisory zone, if the LINKS1000/GSM1000
experiences a trouble, the zone will be violated, causing the
panel to report the event to the central station. This type of zone
always requires a single EOL resistor (5600Ω).
