3-19
Long Range Radio Connected to the ECP
The control can support an ECP Long Range Radio
(LRR) (7820, 7835C, and 7845C are supported) that
connects to control panel’s keypad terminals. All
messages programmed for transmission via the phone
lines may also be sent via the LRR. These messages
are transmitted in Contact ID format regardless of the
format programmed for the control in fields 45 and 47.
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.
Operation
The VISTA-128BP/VISTA-250BP features
Dynamic
Signaling Delay
and
Dynamic Signaling Priority
message reporting when Long Range Radio 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 Long Range Radio
(1)
.
The chart below provides an explanation of how the
Dynamic Signaling feature functions.

and LRR.
Additional LRR 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 LRR, but Zone 11 will not.
Messages are transmitted from the VISTA-
128BP/VISTA-250BP to the LRR 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 IDs programmed into the
LRR: 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 LRR will not be transmitted.
If the event is to be reported to both phone numbers
(dual reporting), then reporting through the LRR will
be done in an alternating sequence. The first event in
the queue is transmitted to both the primary and the
secondary radio central stations before transmitting the
second event.
If split reporting is selected for the VISTA-
128BP/VISTA-250BP, then the LRR will send the
appropriate reports to the primary and secondary
central stations.
Installing the ECP LRR
To install the ECP LRR, perform the following steps:
Step Action
1 Mount the radio according to the
instructions that accompany the radio.
2 Connect the data in/out terminals and
voltage input terminals of the radio to the
control’s keypad connection points,
terminals 6, 7, 8, and 9. See
Figure 3-29.

Supervision
The data lines between the control and the LRR, as
well as certain functions in the radio, can be
supervised.
If communication is lost or a trouble condition occurs,
both the LRR 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 radio.
