1.2.5 Battery Power Condition
In the event of an
AC power failure, the Control Panel can operate with
battery power.
A power failure causes the following sequence of events to
occur:
o
AC pilot lamp goes OFF
o AC monitor relay (K3) de-energizes
o
AC monitor relay (K3) contacts 1 and 4 close
o
AC monitor relay (K3) contacts 6 and 8 open
o Battery power is applied to Control Panel
o Trouble condition occurs (see Paragraph 1.2.3)
When
AC power is restored the Control Panel automatically restores except
for the ring back feature (due to the Trouble Silence switch (Sl) in the
Silence position). Placing this switch in Normal position turns the
audible Trouble signal
OFF. Appendix C contains information on how to
calculate required battery capacity.
