The Repeater Transmitter PCB (shown in Figure 2 above) is mounted on, and takes its control signals
and power from, the Main Control PCB which is mounted in the MFP Main panel. It drives the
Repeaters over the two wire network, via connector PL7.
Power for the network may be taken from the MFP Main panel, or in cases where there may be heavy
current drawn by the Repeater system, an Auxiliary Power Supply may be fitted, which then supplies
the Repeaters.
PCB Indicators
•
LD1 / LD2 (yellow LEDs) indicate faults on the Programmable Relay and Sounder Cards (not
applicable in Repeater only installations).
•
LD3 / LD4 (yellow LEDs) indicate diagnostic information about the Repeater network.
PCB Controls
•
PLK1 must be linked to disable PSU sense. If an Auxiliary Power Supply is used locally then this link
must be removed. If the link is removed and the Auxiliary Power Supply fails, or is not fitted then
the Repeater will sense a Fault condition and indicate this appropriately.
•
PLK2 is used to select either the MFP Main panel’s Power Supply (LOCAL position) or the Auxiliary
Power Supply (AUX position). One of these positions must be linked out, or the Repeater system
will not function.
•
SW1 and VR1, VR2. These controls are for use with the Programmable Relay and Sounder Cards
(not applicable in Repeater only installations).
In a Repeater only system the position of VR1 and VR2 is not important and SW1 should be left
with all eight switches in the off position.
