isn’t practical, the telephone company may temporarily
discontinue service without notice and you will be notified as
soon as possible. You will be informed of your right to file a
complaint with the FCC. The telephone company may make
changes in its facilities, equipment, operations, or procedures
where such action is reasonably required in the operation of its
business and is not inconsistent with the rules and regulations of
the FCC that could affect the proper functioning of your
equipment. If they do, you will be notified in advance to give you
an opportunity to maintain uninterrupted telephone service.

Chapter 1: Introduction
The Sensaphone®Model 1104 is a fully-programmable,
environmental monitoring system that offers extensive on-site and
remote monitoring capability to small businesses, private homes,
farms, greenhouses, computer rooms, and remote facilities.
Designed for desktop or wall mounting, the Model 1104 is simple
to install, program and operate; no changes to standard electrical
or telephone service are required. Connected to a telephone line,
it will respond to an alarm by dialing up to four separate
telephone numbers. When the call is answered, an “Alert
Condition” message is delivered in digitized speech.
The Model 1104 features built-in sensors to monitor a variety of
conditions:
• High sound level
•AC electric power failure
• Battery backup
• Temperature*
*Note: While technically not a “built-in” sensor, tem-
perature is factory installed on input 1, and if left
installed will limit your additional inputs as listed
below to 3.
1104 is equipped with 4 alert inputs. Additional sensors* can be
added to extend monitoring capabilities to include:
•Intrusion or unauthorized entry
•Water leaks and seepage
•Temperature
• Humidity
•Equipment operation
•Many other conditions that may require unique monitoring
solutions
* Refer to Appendix B for information on additional
sensors (available separately from Sensaphone) best
suited to your application.
The status of each monitored condition is readily obtained at the
unit's installation site, or remotely by telephone. At the close of
every Status Report, time is provided for listening to on-site
sounds.
13

To ensure reliable operation, the Model 1104 features power
backup capability; in the event of AC power failure, six D-cell
batteries (not included) will continue to power the unit for
approximately 24 hours.
This manual comprises the instructions and commands for
installing and operating the Model 1104. The Quick Start chapter
is included to speed understanding of programming and operation.
Communication and Alarm Programming chapters demonstrate
step-by-step methods for utilizing the full range of available
features. The Troubleshooting chapter provides assistance in the
event that problems are encountered.

Chapter 2: Installation
Correctly installing the Model 1104 will ensure proper
functioning of the unit. Please read the entire chapter before
starting the installation process.
Within the packaging will be a Warranty Registration Card.
Please take the time to fill this out and mail. The OneYear
Limited Warranty is explained in the back of this manual.
2.1 Operating Environment
The Model 1104 should be installed and operated in an area that
provides space for wiring sensors to the screw terminals, near an
AC power source and telephone line. Operating temperature
ranges from 32° Fahrenheit (0° Celsius) to +120° Fahrenheit
(+49° Celsius).
NOTE
The Model 1104 is a sensitive electronic device. Do
not install the Model 1104 near strong electrostatic,
electromagnetic or radioactive fields. Do not expose
to fumes or corrosive vapors.
2.2 Mounting
Flat Mount: Place the Model 1104 on top of a desk or other
horizontal surface. Wall Mount: Mount on a wall with two screws
using the keyholes on the back panel of the unit. Place the screws
or bolts 313/16" apart at the desired height from the floor. Hook
the unit over the screws and toward the floor. Refer to Figure 2-1.
Figure 2-1. Wall Mount
313 16"
15

2.3 Power Surge Protection
The Model 1104 can be damaged by power surges and lightning
through the telephone line and the 120 VAC power supply.
Although the Model 1104 has built-in surge protection, we
recommend that additional protection be obtained for the unit and
for any electronic equipment that is attached to your power supply
and telephone lines. Power surge protection is especially
important if you live in a lightning-prone area. The ISOTEL
Surge Protector Model IB-4 is available through Sensaphone, Inc.
See Appendix B.
2.4 Power Supply and Battery Backup
The Model 1104 is provided with an AC power transformer that
will plug into any standard 120 VAC outlet and a battery backup
(batteries not included) that enables the unit to continue
functioning if AC power is removed (due to electric power
disruption or failure). The Model 1104 uses six, D-cell alkaline
batteries. Do not use rechargeable nicad batteries.
NOTE
Be sure that the AC transformer is plugged into an
outlet before installing batteries.
To install the batteries, open the battery compartment hatch
located underneath the unit, align batteries according to the
diagram shown in Figure 2-2, and replace the hatch.

2.5 Starting the Model 1104
When the AC power transformer is first plugged into the electrical
outlet, the Model 1104 automatically starts in RUN mode. The
red LED light will begin to glow. The unit will respond
with,“Hello, this is Sensaphone® 1104.”
2.6 Run Mode and Standby Mode
Pressing the RUN/STANDBY key on the Model 1104 keypad will
alternately activate or deactivate the unit. If the unit is activated
and in RUN mode, the red LED (small red light on the upper right
of the unit’s front panel) glows steadily. In STANDBY mode, the
red LED goes out, but will blink every few seconds to indicate
that power is still supplied to the unit.
In RUN mode, the Model 1104 is able to receive incoming calls
and to dial out automatically in the event of an alarm on one of
the monitored conditions. To enter STANDBY mode, press
RUN/STANDBY.
As soon as the Model 1104 enters STANDBY mode, it responds
with “Have a good day.” The red light immediately goes out and
then resumes with a blink every few seconds. While in
STANDBY mode, all functions are disabled, but programmed
memory is preserved. Upon exiting STANDBY mode, any
currently existing alert conditions will be announced.
NOTE
STANDBY mode is not equivalent to “power off”—
an electrical source, such as the 120 VAC, or the bat-
tery backup, continues to provide full power to the
unit. If the unit is placed in STANDBY mode,
unplugged from the 120 VAC outlet, and placed in
storage, the batteries will continue to power the
Model 1104, discharging until they fail.
Consequently, batteries should always be removed
from the unit following disconnection from any 120
VAC outlet, prior to storage.
Press the RUN/STANDBY key again to return to RUN mode.

2.7 Telephone Line
The Model 1104 will operate with all standard telephone systems
that accept pulse or tone dialing. The Model 1104 cannot be used
on an extension line to dial its own telephone number. Also, it
may not be installed on a party line or pay telephone line.
Certain private telephone systems and public switching equipment
may not accept the Model 1104 dialing or may generate an
unacceptable ring signal. In those cases, a dedicated line may be
required. Consult the supplier of your telephone system if you
encounter problems.
If you do not have a modular telephone extension at the Model
1104’s location, you must contact your local telephone company
to have one installed (there is a charge for this service). If you
have four-pin jacks, adapters are available to convert them to the
modular plugs. Contact your local telephone company or
electronics parts store.
CAUTION
Never install telephone wiring during a lightning
storm. Never install telephone jacks in wet locations
unless the jack is specifically designed for wet loca-
tions. Never touch uninsulated telephone wires or ter-
minals unless the telephone line has been disconnect-
ed at the network interface. Use caution when
installing or modifying telephone lines.
To install the telephone line, plug the modular telephone jack
provided into any standard RJ11 phone outlet.
Refer to Figure 2-4.
Figure 2-4. Installing the Telephone Line

site. The sensitivity of the microphone is configurable and will
detect a continuous as well as a beeping alarm.
Other programming options that apply to the microphone include
setting the length of time before a high sound causes an alarm.
If this sound level exists for 8 consecutive seconds (default) or for
the programmed length of time, the Model 1104 will dial out with
an alarm message.
NOTE
The proximity of the audible alarm to the microphone
is extremely important.
Normally, the Model 1104 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-second
intervals to listen-in to sounds at the Model 1104’s location.
When calling for a Status Report, the microphone permits
listening to on-site sounds for a programmed time interval.
2.9 Alert Inputs
The Model 1104 can monitor up to 4 inputs (represented by the
numbered terminal screws shown in Figure 2-5, below).
Figure 2-5. Alert Inputs
Inputs are configured as either dry contact or temperature. An
input configured as dry contact can be used with any normally
open (N.O.) or normally closed (N.C.) device. “Open” refers to
an opened circuit path; if conditions cause the circuit to close, an
alert condition occurs. “Closed” refers to a continuous circuit
path; if a closed circuit is opened, an alert condition occurs. The
Model 1104 determines the way inputs are configured by the type

of sensor connected to each alert input (refer to Chapter 5,
Section 5.1).
An input configured as “temperature” is designed to evaluate a
range of settings. The Model 1104 will read the temperature at the
sensor’s location and compare that value to programmed high and
low temperature limits. Temperature inputs must be used with
Phonetics Remote Temperature Sensor.
NOTE
Before wiring, it is advisable to disable the inputs to
prevent accidentally tripping an alarm. See Chapter 5,
Section 5.2.
2.10 Installing the Sensor
After you have selected the sensor, loosen the screw of the alert
input and its corresponding ground. Two wire leads are used to
connect any monitoring sensor. Fasten one lead to the numbered
screw and the other lead to GND. Tighten both screws. If the
input was not disabled, the Model 1104 may recite its “Alert
Condition Exists” message as you connect the sensor. If it does,
just press any key to stop it. Re-enable the input after wiring.
Refer to Figures 2-6 and 2-7 for connecting a sensor to an alert
input.
Figure 2-6. Sensor Connected to an Alert Input
Any sensor can be attached to the Model 1104 using 22-gauge
wire. The sensor can be several hundred feet from the unit, as
long as the total resistance of the circuit is not greater than 50
ohms. Use wire appropriate for the application.
