Step 10
– Connect the antenna cable to the radio module. See
Figure 6A
.
Step 11
– Connect the ribbon cable from the radio module to the radio PCB. See
Figure 6B
. Verify that the black wire is aligned with
the right-most pin on the PCB.
Step 12
– Connect the radio PCB data cable to the controller. See
Figure 6C
.
Step 13
– Connect the toggle switch to the controller. See
Figure 6D
.
Note:
Position the switch with the unwired connector at the top.
Step 14
– Loop the antenna wire so that it will not interfere with the controller circuitry and secure it with wire ties.
Step 15
– Connect any sensor inputs to the data retrieval terminal block.
Step 16
– Replace the control panel and the bottom cabinet panel.
Step 17
– Affix the provided labels on the bottom panel. Write the assigned licensed frequency in the provided space. See
Figure 7
.
Step 18
– Set the hand-held radio frequency to match the Retro-Link frequency for proper communication.
Step 19
– Set the toggle switch to
ENABLE
and place the dial selector to the
RAIN OFF
position. Reconnect the main power source
to the controller and test for proper operation.
Troubleshooting Guide
Sentinel Retro-Link does not respond to hand-held or central commands:
More than one station activates when a hand-held command is initiated:
Radio:
Equipment Type – Data radio, MAXON, model SD-125 U2
Frequency Band – UHF
RF Output Power – 2 watt
Current Consumption:
Standby (Muted) – < 65 mA
Transmit 2 watts RF power – < 1.0A
FCC License:
FCC ID # MNT - PC - UC
Electromagnetic Compatibility
Radio complies with FCC Part 22 and Part 90 of the FCC Rules
Domestic:
This equipment has been tested and found to comply with the limits for a FCC Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. The equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to the radio communications. Operation in a
residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own
expense.
– Verify toggle switch is in “ENABLED” position.
– Verify proper and secure wiring and cable installation.
– Verify power to the MC Plus controller.
– Verify continuity of the antenna grounding.
– Verify that the hand-held battery is fully charged.
– Reset the hand-held radios.
– Reset power to the central station.
– Reset power to the MC Plus controller.
– Verify proper and secure wiring and cable installation.
– Replace Timing Mechanism and retry hand-held commands.
