F-Type

Diagnostics

Both One-Way and Two-Way AlarmNet-A radios are each capable of producing manually

triggered diagnostic messages that help determine how an account is performing.

To transmit these messages typically requires that a technician visit the account, however some

radios may have the capability to have a test message triggered remotely via the use of the central

station’s AlarmNet Console.

In any case, whenever an F-Type Diagnostic message is produced by a subscriber account and is

detected by any of the network’s Master Stations, it is evaluated and then reformatted for delivery

to the central station. Unlike the A-Type Diagnostic, the F-Type Diagnostic can provide more

practical information to the central station that can be directly utilized to obtain the best radio

performance possible. Each network node that has received the radio’s transmissions formulates

an F-Type Diagnostic message. The message sent to the central station contains data on the

signal strength, frequency, and modulation characteristics of the signals produced by the

subscriber radio being evaluated.

Note: The manner in which One-Way and Two Way radios are manually triggered to produce F-

Type Diagnostics are covered in their respective Installation Instructions. While the quantity of

such messages produced will vary among Two-Way radios. One Ways are designed to transmit

approximately 60 such messages over an interval of several minutes.

Illegal

(Unregistered)

subscriber

This message is received when a radio is programmed for an account that does not exist in the

AlarmNet database. The account number that is being transmitted is displayed in the message.

When such a message is received, the central station should check with its installers and/or

dealers to identify recently installed radios, and confirm whether or not there was an error in

programming the subscriber account number for one of them. If the source of the report can not

be determined, contact AlarmNet Technical support. (Note that there is no restore message

associated with this condition)

keyed-on

subscriber

This message indicates that a subscriber is continuously transmitting. Such reports may be sent at

intervals of about six minutes, and from each network node detecting the condition. Under the

worst conditions, such a radio will transmit until it is physically powered down. Action may be

required. Contact AlarmNet.

If the report for a keyed-on subscriber is received, note the account number, the reporting node,

and the time. It is likely that additional reports of the same event will be received from other

network nodes that hear the radio being reported. Six minutes later, not if any subsequent reports

of the same event are reported. If so, contact AlarmNet technical support at (800) 222-6525.

Based on instructions from AlarmNet, you may need to have the service personnel that are

responsible for the radio disabled it.

Loss of ECP

Supervision

Applies to the 7845C radio only when used with the 4229 zone expander module or when

programmed for 4204 emulation mode. The radio is connected to the panel in either of these

modes, using the ECP bus (Enhanced Console Protocol aka keypad wiring). In either of these

modes, if the radio detects that it is no longer in communication with the control panel, it will
