SA 05 Automatic Changeover Unit, provides constant monitoring of
public address system amplifiers and automatic changeover of faulty
amplifiers to a standby amplifier in the event of a fault. The unit
is designed to work seamlessly with the amplifier supervisory module
attached to the amplifier, which provides a signal to the SA 05
when a fault is detected.
single SA 05 unit is capable of monitoring up to five duty amplifiers
and one standby amplifier. Multiple units can be cascaded to serve
more than five duty amplifiers by a single standby amplifier.
SA 05 also provides audio and visual indication upon detection of
a fault, thus the operator can service or replace the faulty amplifier.
In view that the integrity of the public address system should not
be compromised at any time, the SA 05 is essential in every public
address setup to supervise the duty amplifiers of the system.
