CHAPTER 3 CONTROlS AND FACIlITIES
i. Voted Alarm*
A voted alarm is caused by the simultaneous presence of an identical
alarm on more than one control channel within a preconfigured
group. The relevant LED (A1, A2, A3, Fault, Inhibit) will illuminate
as described in Section 2.3.1 on the control cards with the alarm
conditions and the message display of the control card designated
the Vote Master Card will show VOTE.
Vote compensation may be applied to the voted alarm output
operation by selecting one of the following configurations:
a. No compensation.
b. Faults counted as alarms.
c. Faults and inhibits counted as alarms.
d. Vote count reduction on faults.
e. Vote count reduction on faults and inhibit.
Vote compensation is useful to ensure that sensors in fault (or inhibit)
do not prevent voted alarm outputs.
Note: Vote compension should not be used with software Version
1V5 or earlier.
j. Update Alarm
The update alarm facility provides a common alarm indication
whenever a new alarm occurs, even if a previous alarm condition
exists. The update alarm can be configured to operate on a single
card or on a grouped alarm e.g. master or zoned. The update alarm
is especially useful in systems configured with only master or group/
zone relays, where the occurrence of subsequent alarms will not
cause further relay output compared to that caused by the initial
alarm. The relevant LED (A1, A2, A3, Fault, Inhibit) will illuminate
on the control card with the alarm condition as described in Section
2.3.1. The ATTN LED will also illuminate as described in Section
2.3.2b and the message display will show the cause of the update
alarm, e.g., -FT-, -IN-, -A1-, etc.
When relays are used for signalling update alarms, no other alarms
or messages must be allocated to them.
Note: Update alarms should not be used with software Version 1V5 or
earlier.
