Removing Modules

If a module is no longer required on the system the panel must be told to no longer supervise the module. To
do this remove the module from the Keybus and perform the Enable supervision function again ( See Section
2.7 "Enable Supervision"). The panel will see the module has been removed and will no longer supervise it.
2.9

Zone Wiring

For a complete description of the operation of all zone types, please refer to Section 5.1 ("Zone Definitions").
There are several different ways in which zones may be wired, depending on which programming options
have been selected. The panel can be programmed to supervise normally closed, End of Line, or Double End
of Line loops. Please refer to the following diagrams to study each type of individually supervised zone wiring.
Any zone programmed for Fire or 24 Hour Supervisory must be wired with a single End of Line (EOL)
resistor regardless of the type of zone wiring supervision selected for the panel (section [013],
options [1] and [2]). See Section 5.2 "Zone Programming."
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.

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, programming section [013], option [1] must be
OFF and option [2] must be ON.

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 Supervisory zones. Do not wire
Fire zones to keypad zone terminals 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. Wiring multiple detection
devices or contacts on a single loop is not allowed .
