Overview
Automatic Amplifier Switch
The AS12 Automatic Amplifier Switch continuously monitors the outputs of paging amplifiers to
detect failures. If it detects a problem it will switch the defective amplifier out of the circuit and
activate the standby amplifier. The appliance is capable of simultaneously monitoring four amplifiers
plus a standby, and provides visual indication of amplifier status.
As part of an integrated industrial emergency/communications system, the AS12 ensures
uninterrupted communication in the event of an amplifier failure.
The AS12 Automatic Amplifier Switch is one component in Guardian Telecom's full line of paging
system products, which also includes alarm tone generators and distribution amplifiers.
