purpose of maintaining a secure radio connection while the alarm system is violated, the power-

up reset message will be sent to the central station from the new radio, thereby alerting the central

station to the possibility of such a condition.

If the reasons for receiving this message cannot be immediately explained with positive

confirmation as to one of the above conditions, it is possible the radio is being tampered with and

it is recommended that it be treated as an alarm and action be taken in accordance with the central

station’s normal procedures.

If this message is received reference the central station (i.e. Account # 0000) this indicates that

the central station 685 receiver has been reset. This action would also reset the central station

radio transceiver, which would generate this message.

Redundant

supervision

warning

This message indicates a potential problem with the local AlarmNet-A network. The AlarmNet-A

networks are designed with overlapping coverage, and often two nodes are designated as being

responsible for the supervision of a subscriber radio. This message indicates that an AlarmNet-A

network node is down (not working), and that node is responsible for supervising at least one

subscriber belonging to the central station as either a primary or secondary node. Note that this

message does not indicate which node is down, or which subscribers are affected. It simply

indicates that there may be a potential problem with the supervision of one or more subscribers.

Keep in mind that many accounts are supervised by two network nodes, and alarms are repeated

multiple times and handled by any node that hears them. If the central station is equipped with an

AlarmNet Console, you may use the (N) Network Status function to determine which of the

network’s node (Master Stations) are down. Once the problem node has been identified, you may

determine which subscribers are affected by the problem by reviewing the Central Station Report

that is sent to the central station each month.

Repeating alarm

suppressed

The primary node responsible for this radio detects five separate but identical alarm reports within

an 8-minute time period. The first five alarms are reported as the network normally would deliver

them. However, instead of the sixth alarm, the “Repeating Alarm” message will be sent. Future

messages that are identical to the suppressed alarm will not be sent for the next 25 minutes. It is

impotant to note that unless the radio has been programmed to generate restore signals, the

network will be unable to produce the “Repeated alarm” message, and in this case all repeated

alarms would be reported to the central station.

Status Message Another name for A-Type diagnostic. See “A-Type diagnostic”

Supervision

interval

A time period during which the network expects to receive a signal or poll response from a radio.

The network will then check with other network nodes to determine if the radio was heard

elsewhere. If it is determined that the radio has indeed failed to respond during this interval, it

will be considered in Communication Failure, and a Comm Fail message will be sent to the

central station.

Swinger A frequent and generally unwarranted repetition of the same alarm condition. (Note, ‘swingers’

are rarely the fault of the radio itself and are almost always related to the sensors or wiring of the

alarm system.

Swinger

suppression

A method to reduce unnecessary alarm reports. See “Repeated Alarm Message”
