Appendix C: External Alarms
Other pieces of equipment can be alarmed by connecting relay outputs into the
external alarms of the MirrorCell II. An alarm condition will be generated when the
open collector input is pulled to common ground. The input has a very weak pullup
resister in circuit. The external alarm inputs can be physically connected either on the
alarm terminal-strip as pictured in figure C-1 or directly to the DC Distribution board on
the labeled jumper. The software should be configured to not alarm any external alarm
not physically connected to the repeater. The software alarms for the external alarms
are in order and number 13 to 16. Alarm 9 corresponds to the Batt Backup alarm input
and is used to alarm BBU systems attached to the repeater.
