Re: Strange Fire Alarm Activity

["Just Some Guy" <notarealaddress@xxxxxxxx>]

Since it is an old school, does it have a clock system?  Often the old
clocks syncronize at some ungodly hour.  Perhaps the sync pulses are setting
it off?  Perhaps the fire alarm wire is run in the same conduit, not unusual
for the old systems where everything was 120 VAC.
