2.6 Supervision

By default, all modules are supervised upon installation.

Supervision is enabled at all times so that the panel can

indicate a trouble if a module is removed from the system.

A connected module which does not show as being present

will appear as a trouble condition and the Trouble light on the

keypad will turn ON. This condition may be due to one or more

of the following reasons:

• the module is not connected to the KEYBUS

• there is a KEYBUS wiring problem

• the module is more than 1,000'/300m from the panel

• the module does not have enough power

For more information regarding module supervision troubles,

please refer to

Section 3.4 (“[Section 3.4 (“[

Section 3.4 (“[

✱✱

✱

] [2] Trouble Conditions”).] [2] Trouble Conditions”).

] [2] Trouble Conditions”).

Modules will not be automatically supervised if

connected while in installers mode.

2.7 Removing Modules

The panel must be instructed to no longer supervise a

module being removed from the system. To remove the

module, disconnect it from the KEYBUS and reset the

supervision field by entering [92] in the installer’s

programming

The panel will be reset to recognize and

supervise all existing modules on the system.

2.8 Zone Wiring

For a complete description of the operation of all zone types,

please refer to

Section 5.2 (“Zone Definitions”).Section 5.2 (“Zone Definitions”).

Section 5.2 (“Zone Definitions”).

There are several different ways in which zones may be

wired, depending on which programming options have

been selected. Please refer to the following diagrams to

study each type of individually supervised zone wiring.

Any zone defined as Fire or 24 Hour Links Supervisory

will automatically require a single End of Line (EOL)

resistor regardless of which type of zone wiring

supervision is selected

(See Section 5.2 “Zone

Definitions”)

Reconfiguring the zone supervision from

a non-default setting—from DEOL to EOL or from NC

to DEOL—may disable zones 1-6 while open or in

trouble. To prevent this situation, the system should be

powered down completely and powered up again.

2.8.1 Normally Closed (NC) Loops

This option should only be selected if Normally Closed

(NC) detection devices or contacts are being used

2.8.2 Single End Of Line (EOL) Resistors (5600Ω)

This option should be selected if either Normally

Closed (NC) or Normally Open (NO) detection

devices or contacts are being used

2.8.3 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.

This option can only be selected if Normally Closed

(NC) detection devices or contacts are being used

(ie: Do not use DEOL resistors for Fire zones or

LINKS Supervisory zones).

Only one NC contact can be connected to each

zone. Multiple detection devices or contacts on a

single loop is not allowed

The following chart shows zone status under certain

conditions:

• Loop Resistance ............................... Loop Status

• 0Ω (shorted wire, loop shorted) ....... Fault

• 5600Ω (contact closed).................... Secure

• Infinite (broken wire, loop open) ...... Tamper

• 11200Ω (contact open) .................... Violated
