Section 3 - Installing the Control
3-25
Communicators Connected to the ECP
The control can support an IP or GSM communications device (7845i-ent, 7845i-GSM, or 7845-GSM) that connects to
control panel’s keypad terminals. All messages programmed for transmission via the phone lines may also be sent via
the communications device. These messages are transmitted in Contact ID format regardless of the format programmed
for the control in fields 45 and 47. The 7845-GSM and 7845i-GSM communicators may currently be used for Commercial
Burglary systems only.
We recommend that, if possible, you use Contact ID for the main dialer. If Contact ID is not used, certain types of
reports are not sent.
Supervision
The data lines between the control and the communications device, as well as certain functions in the Communicator,
can be supervised. If communication is lost or a trouble condition occurs, both the communications device and the
control’s dialer can be programmed to send a Trouble message to the central station.
NOTE: For complete information, see the Installation Instructions that accompany the Communicator.
Operation
The VISTA-128FBP/VISTA-250FBP features Dynamic Signaling Delay and Dynamic Signaling Priority message
reporting when a Communicator is used. These message outputs are accessed through data fields ✱56 and ✱57,
respectively. The Dynamic Signaling feature is designed to reduce the number of redundant reports sent to the central
station.
The feature is described as follows:
Dynamic Signaling Delay (Field ✱56)
Select the time the panel should wait for acknowledgment from the first reporting destination before it attempts to send
a message to the second destination. Delays can be selected from 0 to 225 seconds, in 15-second increments.
Dynamic Signaling Priority (Field ✱57)
Select the initial reporting destination for messages, Primary Dialer (0) or Communicator (1).
The chart below provides an explanation of how the Dynamic Signaling feature functions.
If Priority
(✱57) is…
And message is… Then…
Acknowledged before delay expires Message is removed from queue and no message is sent to
communications device.
Primary Phone
No. ("0")
Not acknowledged before delay
expires
Message is sent to both the Primary Phone No. and
communications device.
Acknowledged before delay expires Message is removed from queue and no message is sent to
Primary Phone No.
Communicator
("1")
Not acknowledged before delay
expires
Message is sent to both the Primary Phone No. and
communications device.
Additional communications device reporting options are defined by selecting the events for each subscriber ID in fields
58 and 59. The reporting events are Alarms, Troubles, Bypasses, Openings/Closing, System Events, and Test. Also,
within an enabled category, the specific event must be enabled for dialer reporting. If, for instance, zone 10 is enabled to
report, but zone 11 is not, zone 10 will report via the communications device, but zone 11 will not.
Messages are transmitted from the VISTA-128FBP/VISTA-250FBP to the communications device on a “first in/first out”
basis. If events occur at the same time, they are transmitted in order of priority. The priority from most to least
important is : Fire Alarms, Panic Alarms, Burglary Alarms, Fire Troubles, Non-Fire Troubles, Bypasses,
Openings/Closings, Test messages, and all other types of reports.
There are two subscriber ID’s programmed into the communications device: primary and secondary. These correspond to
the two subscriber ID’s programmed into the control for each partition. If a subscriber ID for a partition is not
programmed (disabling reports to that central station), the events enabled for the corresponding subscriber ID in the
communications device will not be transmitted.
If the event is to be reported to both phone numbers (dual reporting), then reporting through the communications device
will be done in an alternating sequence. The first event in the queue is transmitted to both the primary and the
secondary Communicator central stations before transmitting the second event.
If split reporting is selected for the VISTA-128FBP/VISTA-250FBP, then the communications device will send the
appropriate reports to the primary and secondary central stations.
