1678 RFD OPERATION MANUAL 8
2.4.3. Power ON Self Test: Upon installing the antenna and pressing the “ON”
switch, a rigorous self test is initiated. If a failure of the self test occurs, the green
receive light (RX) will blink continuously and it will not be possible to operate the unit.
Contact the Manufacturer for service. Do not attempt to use a failing unit.
2.4.4. Display Panel Light Dimmer Circuit: With the unit powered on, Repress
the ‘ON’ switch briefly to toggle the LED display light’s intensity between bright and
dim. When the unit is turned on, the last chosen intensity setting is restored.
2.4.5. Select Remote Units: Depress the Select Switches “1” through “4” or “8” to
select independently the Remote Units that will communicate with the Controller. Any
combination of the four or eight Remote Units may be selected. The yellow SELECT
light on the switch indicates if the Remote Unit programmed for that switch is selected.
Press the switch again and the yellow SELECT light for that Remote Unit will be
turned off indicating the Remote Unit is not selected.
2.4.6. Request Remote Unit Status: Depress the “STATUS” switch to transmit a
status request signal to the selected Remote Units. The selected Remote Units will
transmit their current status to the Controller. If none of the Remote Units are
selected, the Controller will request status from all of the Remote Units. Any
answering Remote Units will be selected automatically. If the Controller is within
range of the Remote Unit transmitter, the status of the selected Remote Unit will be
presented on the display panel with a steady light. If the Controller is out of range of
the Remote Unit transmitter, the status will be assumed from the last command sent to
that Remote Unit. In that case the assumed status of the Remote Unit will flash on the
display panel.
2.4.7. Arm the Remote Unit: Depress the “ARM” switch for 1/2 second and the
Controller will transmit the Arm command to the selected Remote Units. The red
ARMED light at the selected Remote Units will flash on the Controller display panel
until the firing capacitor charging time is completed. The Controller then requests
status of the selected Remote Units. If the Controller is within range of the selected
Remote Unit transmitter, the ARMED red light for that Remote Unit will be on steady
on the Controller display panel. If the Controller is out of range of the selected
Remote Unit transmitter, the red ARMED light for that Remote Unit will continue to
flash on the Controller display panel. If the Fire command is not sent within the Arm
Time Period, the system will disarm automatically.
