Annunciator Sequences and Options
K-2 Verbatim Owner's Manual
Audible indications for the channel states are also given. These take the form of
voice reports either from the speaker or over the phone. These reports may be
requested at any time by pressing the CHECK STATUS key, or phoning the
unit.
Whenever any channel is in the unacknowledged alarm or RTN state, the
Verbatim will solicit acknowledgment by phoning personel. The calling
sequence itself is determined by the alarm call grouping and alarm ready
scheduling configuration.
All audible indications can be silenced by pressing the ARM/DISARM key on
the front panel. This action will also always acknowledge all unacknowledged
conditions. Also, all annunciator state transitions and actions are suspended
whenever the box is in program mode. Channel state transitions will still occur.
The annunciator state may at any time be completely reset by pressing the
ARM/DISARM key twice. This action will also reset the state of each channel.
In terms of ANSI/ISA-S18.1 , there is one more property that all Verbatim
annunciator sequences share: there is no support for the first out sequence
designations ( F1, F2, F3 ). Groups of alarms and RTNs are always registered,
reported and reset without regard to which one tripped out first.
K.1 Standard Annunciator Sequence (Manual
Reset)
This section describes the default annunciator sequence used by the Verbatim .
It is a minor variant of the
ANSI/ISA-S18.1 designation M-1 (Manual Reset with
silence pushbutton). It may be configured by entering code 923 1 in program
mode.
Operations in this sequence are detailed in Section 5. Briefly, channel states
transit from normal to alarm when criteria violations persist for the trip delay.
The alarm state is then locked in until acknowledgment is made. The transition
from acknowledged back to normal happens upon manual reset or expiration
of the alarm reset timer. The RTN states are omitted from the sequence.
The annunciator states include only those visual and audible indications
described above. Also, the annunciator sequence follows the transitions
described there too.
This sequence differs from the vanilla
M-1
designation in two ways. The first
involves the operation of the automatic reset timer. The true
M-1
sequence is
obtained by turning the alarm reset timers off (code
922
). The second
distinction involves configurations where no phone numbers are programmed.
Here the transition from alarm to acknowledged happens automatically and
immediately. There are never any audible or visual indications of the
unacknowledged state. This sequence has ANSI designation
M-1-5-6
.
