Removing RF Zones

Removing RF zones is a two step process. First, the
zone must be removed from the receiver using the
procedure below. After the zone has been removed
from the receiver you must then remove the zone
from its zone programming address (0026-0145) by
setting the appropriate zone programming address
to 00.

From the Main Menu, select “Removing RF Zones” (selection 3).

• If no RF zones addresses have been programmed or “Added”

the following message will be displayed:

• If there are RF zones that may be removed, the first available

zone will be displayed:

• You may select the zone displayed by pressing the [#] key or

advance to another zone by pressing the [On] key. If the [#] key is
selected at this time, the panel scans the receiver to remove the
ID for the specified sensor. When completed, the display shows
the following message:

• Pressing the # key at this time will present the next zone that can

be removed. Press the “Off” key to exit the Remove Zone mode.

RF Zone Troubles

RF Zone Troubles will only appear on the display after a user code
followed by [#] [8] [7] has been entered into the keypad. One or
more of the following messages will appear if there is a problem
with a RF Zone:

• Missing Zone indicates that the receiver failed to receive a report

from the sensor during the supervisory period of 4 or 24 hours.

• Trouble Zone indicates that the RF sensor has determined that

there is some type of trouble with itself. Not all types of sensors
have the capacity to report troubles.

• Zone Trouble indicates that a RF zone was programmed as

“Trouble On Short”. RF zones must be programmed as “Alarm On
Short”. See Sections 11.2-11.4, Zone Programming.

• Tamper Zone indicates that the cover tamper has been violated

on the detector.

• Low Battery indicates that the sensor battery is low. This

message will remain until the battery is replaced and the
sensor sends a signal (alarm, tamper or supervisory) to the
receiver.

Receiver Trouble Displays

Receiver #1 refers to the receiver with the lower zone
numbers. Receiver #2 refers to the receiver with the upper
zone numbers.

Removing a receiver from the system will cause zone
faults for all zones assigned to that receiver. To disable
the faulted zones, see Sections 16.3 and 11.3.

The Keypad displays may show the following receiver troubles:

• RF Receiver Tamper indicates that one of the receiver’s covers

have been removed or tampered with. Receiver #1 refers to the
receiver with the lower zone numbers.

• RF Receiver Jammed indicates that the receiver may be getting

interference from outside sources. Such types of interference
may be caused by older Cell Phones, multichannel cordless
phones, some business/police/fire band radios and “Walkie
Talkies”. Receiver #1 refers to the receiver with the lower zone
numbers.

• RF Receiver Trouble indicates that the receiver has not received

any supervisory signals from the sensors during the supervision
interval. Check the receiver antennas and test all the sensors. If
the sensor tests are unsuccessful, then the problem is likely to be
in the receiver. Receiver #1 refers to the receiver with the lower
zone numbers.
