INTRODUCTION
The Ambient Level Controller (ALC) constantly monitors
room noise and adjusts the paging level to accommodate
for any changes in noise level. It has a built-in Sound
Pressure Level (SPL) meter.
SPECIFICATIONS
The ALC has two inputs, a loop start input (Telco) and a
balanced 600 Ohm line input. The Telco input shall have
priority over the line input. The microphone can be placed
up to 5000 feet from the ALC with shielded wire. The ALC
has five contact closure clock or remote control inputs. The ALC has four double throw relay outputs that
activate on the -6 dB and 0 dB levels.
The ALC adjusts page system level in 6 dB steps. The Telco input is loop start and has priority over the
line input. The line input has a dry contact closure which will provide an isolated dry contact closure at
the connections of the line output.
