Summary of Features

PAGE 11

Cater for 8 duty and 1 standby
Expandable for 1 standby to cater for more than 8 duty amps.
Built in Pilot Tone generator, transmit in intervals and senses at sequence to protect 

amplifiers

Overloading protection by allowing only a single take over

Prioritised changeover where the lower numbered amplifier shall be preferred for 

take over if more than two units are down
Short fault detection time within 20 seconds
Changeover at input and output section simultaneously ; suitable for matrix system 

installations

Input link switch ; making connection of channels sharing the same source easier

Channel isolation switch for unused or un-monitored channel

Individual channel status indicators ; normal, fault and changeover status
