AES 7788 Series RF Subscriber Unit ─ Installation and Operation Manual
AES Corporation 35 40-7788, Rev 6, August 30, 2016
4.8 Local Status Check
HandHeld Programmer: <SHIFT> + <F4> PC Terminal: <d>
This function performs a quick diagnostic check at any time. Use the handheld
programmer: press <SHIFT>+<F4>. The following message appears:
SUB [rev#] 7788F
ID#:[NNNN] (C)YYYY AES
RT1:NNNN LEVEL: NNN
STAT:NNN NETCON: N
EXPLANATION OF STATUS CHECK TERMS
Top Line: Indicates Subscriber model and firmware revision information.
ID#: 4-digit ID number programmed into this unit.1
YYYY: Indicates Copyright year.
RT1: Route #1, the ID of the first Subscriber that will be attempted in route to
the central station. If RT1 is 0000 or an IP-Link ID, the unit is attempting to
communicate directly with the central station or IP-Link. If XXXX appears, the
unit is not on the network. Any other 4-digit ID indicates the unit at the top of the
routing table.
Dynamic Routing Table: Each subscriber unit maintains a list of up to 7
alternate IDs. IDs are prioritized according to signal strength and NETCON
ratings. This function is dynamic, and is updated constantly.
LEVEL: Refers to the subscriber unit “level" or "link layer”, which suggests the
expected number of “hops” the message packet might make to get to the central
station or IP-Link. In general, if the number is 1, then this unit is attempting
communication directly with the central station or IP-Link. If the number is 2, the
unit expects to relay its message through one other subscriber unit to reach the
central station or IP-Link. If the number is 3, the message goes through 2 other
subscribers ... and so on. Also, the level number of subscriber with a weak signal
to the unit on the top of its routing list will be incremented by 1. A unit level =
255 indicates that unit is not on network.
STAT: Status shows the self-test data
(Refer to Section 3.8 for explanation and resolution.)
NETCON: (NETwork CONnectivity) An internal rating used in the automatic
positioning of this unit in the network. The range is from 0-7, 0 being best. Note
that while a low number is better, any NetCon from 0 to 6 is OK. 7 may indicate a
problem with this unit or a unit in its path to the central receiver.
All Fire Alarm installations require a NETCON of 0 to 5
Minimum criteria for a "good" repeater are as follows:
1. RF signal exceeds good threshold
2. No faults indicated in status (such as low battery)
3. Level/Link Layer of Subscriber/IP-Link is less than or equal to this
unit’s
4. Signal received from Subscriber/IP-Link at least once every 6 hours
