THE MICROPHONE
The 4100 is provided with a microphone on a 25' cable to monitor high sound level at your
location. It is pre-wired to screw terminals 13 and 14. The microphone will continuously
listen for a high sound level that increases approximately 10 decibels over the normal sound
level at a frequency of about 1000 Hertz or more. (NOTE: The sensitivity of the
microphone can be changed. See Chapter 4, “Sound Alarm Monitoring Sensitivity.”) If this
sound level exists for 8 consecutive seconds or longer (such as with a smoke alarm or
burglar alarm), the Model 4100 will dial out with an alarm message.
NOTE: The location of the audible alarm in relation to the microphone is extremely
important. Normally, the 4100 and the audible alarm must be in the same room. The
maximum distance can vary considerably depending on the alarm, the acoustics, and the
size of the room.
During an alarm dial out, the microphone allows four 4-second intervals to listen-in to the
Model 4100’s location.
During a call in for a status report, the microphone allows you to listen to on-site sounds for
the user-programmed time interval.
ALERT INPUTS
The Sensaphone Model 4100 can monitor up to 4 dry contact inputs. (The fourth input is
the AUX TEMP terminal. See page 11 for details). Each input connection consists of two
terminal screws. One marked: INPUT 1 (screw #3), INPUT 2 (screw #4), INPUT 3 (screw
#5), or AUX TEMP (screw #12). The other marked: COMMON (screws #6, #10, or #14).
See figure 4:
Figure 4: Alert inputs
An alert input can be used with any normally open (N.O.) or normally closed (N.C.) device.
Open is when there is no contact and closed is when a contact exists. The Model 4100 will
adapt to N.O. or N.C. sensors when the unit’s ID number is programmed (see Chapter
3,“Unit ID Number,” or Chapter 4, “Configure Input Normality”). You must determine what
type of sensor will be connected to each alert input.
