Relay, Strobe, Horn and Audible Status Bar Operation
The FCS has four internal SPDT dry contact relays labeled RL1, RL2, RL3 and RL4.
Strobe, horns and the internal audible buzzer are also counted as relays.
The FCS may also have remote relays (RLY-4 and/or RLY-8) connected to it.
The Relay Status Bar on the main display of the FCS shows a summary of the status of the
relays, which includes the internal relays, remote relays and any remote strobes and horns. If
the relays are in different statuses, it will display the three most important statuses in order
from left to right. The bar will also change colour depending on the severity of the status.
This example indicates no relays are active and none are in ON or OFF delay:
