AMBIENT LEVEL CONTROLLER
V-5335621
by
PagePac®
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 fourdouble 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.

Figure 5. Power Supply Connection
Clock Control or Remote Control of Levels [Manual Override] (see Figure 6)
In the case where a user wishes to control the system level by the time of day, it is a simple matter with
the ALC. Use a clock with four separate dry contact closures assigning each to a different time of day.
So long as the contacts are closed the level selected will override the front panel controls. Should two
contacts be closed at the same time the lower level selected will have priority. Also a manual normally
open switch may be used to achieve this result.
Control of External Devices [Relay Outputs] (see Figure 6)
The ALC provides for control of external devices that need activation at maximum noise levels. This is
provided by four sets of dry contact closures on the back panel. These activate at -6 and 0 dB levels.
This can be used for priority override of remote level controls, strobe activation or similar applications.
Set the manual level control to automatic [Blue knob] (see Figure 7). This allows the ALC to calibrate
itself. The automatic position will allow the ALC to constantly change the paging level to compensate for
the changes in noise level in the area being monitored.
Check the SPL meter [Green LED] (see Figure 7) for maximum noise level. This is your high noise level
reading. Then set the maximum noise level control [Red knob] to the average high noise level. If you
feel the room noise may actually be louder at some time, move the control up one click to the right
[clockwise].

FM-14 Log Current Microphone (see Figure 8)
The wire for the FM-14 Log Current Microphone does not have to be shielded. This can be a phone line
existing in the building. Use a RJ-11 connector at the microphone. When connecting the MIC, use a
RJ-11 connector or wire directly to the terminal strip marked MIC ONLY.
Figure 8. Connection of the FM-14 Log Current Microphone
Manual Use of the Ambient Level Controller (see Figure 7)
The ALC may be used without the FM-14 MIC. In this mode the ALC becomes a leveler or limiter for a
manual control of the sound system. The Telco input or the line input may be in this mode. The SPL
meter will not function but all other functions will work in the normal way. The manual level control on the
front panel will set the level of the sound system [Blue knob].
