Fire-Lite Panels Suggested Firmware Upgrade

Document: FLSB15-1-1

Fire-Lite Alarms has identified a firmware issue that could potentially aff=
ect the operation of the Signaling Line Circuit (SLC) when using the follow=
ing addressable Fire Alarm Control Panels; MS-9050UD(E),MS-9200UD(E),MS-920=
0UDLS(E),MS-9600(E) and MS-9600(UD)LS(E).

The following conditions must all be present for a system to be affected:

The Fire Alarm Control Panel Signaling Line Circuit is operating in CLIP mo=
de
A CMF-300 module is installed on the Signaling Line Circuit
The occurrence of an End of line resistor becoming damaged in a way that ch=
anges its value from 47k ohms to a value between 89k-101k ohms while instal=
led on the CMF-300 module

If all of the above conditions are present, the Signaling Line Circuit beco=
mes unresponsive and will no longer process SLC events and no trouble would=
 be indicated.

Given the low probability of a resistor value changing in this way, Fire-Li=
te Alarms is not requiring a firmware upgrade. Upgrading the firmware will =
eliminate the possibility of this issue affecting a system.
