CHAPTER 3 CONTROLS AND FACILITIES
j. 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 on the
control cards with the alarm condition and also on the control card
designated the Vote Master Card (unless it is fitted with a High
Integrity Relay).
Vote compensation (Version 2V6 and above Software only) 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.
k. Update Alarm (Version 2Vx Software only)
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
channel or on a grouped alarm. eg. 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.
When relays are used for signalling update alarms, no other alarms
or messages must be allocated to them. Configuration of update
messages for "inhibit" should be avoided.
l. Rising Alarm
A rising alarm is caused by a rising level of the parameter being
measured crossing a preconfigured threshold and will also cause the
associated alarm LED to illuminate.
