Relay 3 functions as an Alarm relay and monitors the condition of the communication link between the
Central and Remote units. Relay 3 is activated when power is applied and the communication link
between the Central and Remote is functioning. Relay 3 will become deactivated (Alarm condition)
when either the Relay 3 input on the remote is active OR the Remote unit is unable to communicate
with the Central unit.
