4. Verify polling loop voltage on the control panel and at the RPM.
a. This should be fluctuating between 7-12 VDC.
b. Verify that the wires are the correct polarity and on the correct terminals.
5. Verify that all devices are correctly wired.
a. It is often easy to misinterpret our instructions and connect devices incorrectly.
b. This includes panel connections, RPM connections, and field wiring.
6. Verify that the zone programming is correct:
a. Correct input type
b. Serial number and loop number if applicable.
c. If using serial devices, attempt to manually enroll the serial number. This verifies that the panel is
able to talk to the device as well as the proper serial number.
7. *86: On all control panels from 4140-4140XMPT2, Vista-40, and Vista-50, *86 allows a single 4208 to
operate as zones 10-17.
a. With this field enabled, no other polling loop devices will operate.
b. There is a special dip-switch configuration that allows this mode.
c. The Vista-50P and higher controls do not have the *86 option. The First Alert FA1000-FA1340c
have *86. The FA1500c and FA1600c and up do not.
8. Isolate the zone by removing all other polling loop devices; connect a single module directly to the panel.
9. Set the RPM for serial mode (if it can) and try to manually enroll the device.
a. If using dip-switch devices, try setting the RPM for another address; or switch this address with
that of a known good RPM.
10. Consult items under “Random Checks” on
Page 3.
Slow Zone Response
If there is an extreme amount of activity on the polling loop (i.e. 50+ motions tripping at once, etc) the panel may
start to delay the display of restore of zones. This abundance of activity, to the Global Poll logic, will cause the
prioritization of the events and start processing faults/alarms before restores.
In addition to the Global poll prioritization, the panel’s processor will start to prioritize the status updates sent to the
ECP (keypad) data. This will result in a delay of the restore display, all of this can add up to one or two minutes
before the keypad displays the restore of a zone.
This is more noticeable when partitioning. A partition with only a few zones will notice latency in restores due to
large amounts of activity on another partition. A solution would be to use SMART motions on a panel that supports
the SMART motion feature on large installs like this.
This will not cause a slow display of faults/Alarms on the polling loop. Faults/Alarms should display within 5
seconds even on a fully loaded busy panel. If Faults/Alarms are slow, check the following:
1. Verify that there are no ECP devices enabled in programming, that do not exist. The easiest way to do this
is by requesting an ECP LIST from the COMMANDS menu on the compass communication screen.
2. Check troubleshooting section under “
Random Checks” and note 1 under “General Notes”.
