and 294AL-003 S.M.A.R.T. Emergency Phones
Getting Started
Product Overview
Thank you for your purchase of a GAI-Tronics S.M.A.R.T., ADA-compliant, emergency telephone. In
addition to providing standard emergency telephone operation, GAI-Tronics Self-Monitoring and
Reporting Telephones (S.M.A.R.T.) incorporate leading-edge technology to provide optimum
performance and flexibility. For example, when used with the GAI-Tronics Telephone Management
Application (TMA) the health of each telephone is monitored and reported. For complete details, please
refer to the on-line help included with TMA.
The following S.M.A.R.T. emergency telephone models are described in this manual:
Model Description
293-003 Surface-mount, glass-reinforced polyester enclosure including an emergency push button,
Braille tag, and visual call received indicator.
293AL-003 Surface-mount, aluminum enclosure including an emergency push button, Braille tag, and
visual call received indicator.
294AL-003 Surface-mount, aluminum enclosure including an emergency push button, call push button,
standard telephone keypad, Braille tag, and visual call received indicator.
297-003 Flush-mount, stainless steel front panel including an emergency push button, Braille tag,
and visual call received indicator.
298-003 Flush-mount, stainless steel front panel including an emergency push button, call push
button, standard telephone keypad, Braille tag, and visual call received indicator.
All of the S.M.A.R.T. emergency telephones listed above comply with the Americans with Disabilities
Act (ADA). Each phone includes a Braille tag for vision-impaired individuals to identify the functions of
the telephone and a visual indication for hearing-impaired individuals indicating that an emergency call
has been answered.
The CALL RECEIVED WHEN LIT LED is the visual call received indicator. When a call is initiated by
pressing the emergency push button, the LED will initially flash. When the telephone is answered and
audio is detected, the LED will light steadily. The LED will remain lit until the call is disconnected.
The GAI-Tronics S.M.A.R.T. Phone product line provides the flexibility to address a diverse range of
applications. A wide variety of functions can be achieved by altering the configuration data stored in the
phone’s non-volatile memory. These configuration options include:
•Pre-programmed auto-dial telephone numbers
•Call termination method (automatic or manual)
•Maximum call duration
•Answering options

02/05
These functions are initially programmed during manufacturing and testing. After installation, they can
be programmed remotely via DTMF data calls, either manually or through TMA. Set the emergency
auto-dial phone numbers in accordance with your security plan. For most applications, the other function
settings will not need to be changed from their factory defaults. For details regarding configurable
options and the factory defaults, please refer to the programming section of this manual and the on-line
help available with TMA.
The emergency push button can be programmed to call three unique telephone numbers. The unique
telephone numbers include a primary telephone number and two backup, or roll over, numbers. In the
event an emergency call cannot connect to the primary telephone number (i.e., a busy signal or no
answer), the emergency phone will automatically dial the first backup, or roll over, number. Again, in the
event an emergency call cannot connect to first backup telephone number, the emergency phone will
automatically dial the second backup, or roll over, number. This sequence will continue either until the
emergency call is answered or the programmed number of retries is reached.
All of the above S.M.A.R.T. telephones are line-powered telephones and can be connected to any of the
following:
•Central Office (CO) line to the Public Switched Telephone Network (PSTN)
•24 V dc or 48 V dc analog station port of Private Branch Exchange (PBX), Private Automatic
Branch Exchange (PABX) or KSU.
Connection may not be made to pay phone extensions or shared service (party) lines.
The phones require a minimum line current of 24 mA to operate. However, when available line current is
below 35 mA, depending on the stability of the telephone line, the telephone’s operation can be affected.
To minimize the effects of lower line current, GAI-Tronics offers a plug-in power supply, Model 40404-
045. Please refer to General Installation Guidelines.

3. As an alternate operation, the emergency phone can be configured to require operator action to light
the CALL RECEIVED WHEN LIT LED. If this mode is configured, the operator lifts the handset, and
presses #(or *) to acknowledge the call and then the CALL RECEIVED WHEN LIT LED will light
steady.
Placing a Non-Emergency Call (Models 294AL-003 and 298-003 Only)
To place a non-emergency call:
1. Press the CALL push button.
2. Wait for dial tone.
3. Use the keypad to dial the desired number.
4. At the end of the conversation, press the CALL push button again to put the phone on-hook.
Receiving a Call
When a S.M.A.R.T. emergency telephone is called, the phone will automatically go off-hook and a
conversation can take place.
Disconnecting Calls
There are several methods included in the S.M.A.R.T. emergency telephones to disconnect calls. There
are both manual and automatic disconnect methods. The disconnect methods include the following:
•Remotely disconnect of an emergency call, operator enters either the # # or *99 control command.
•Manually disconnect an emergency call, press the EMERGENCY button after 15 seconds (can be
disabled).

Installation
ATTENTION Installation should be performed by qualified personnel and only in
accordance with the National Electrical Code or applicable local codes.
Safety Guidelines
When installing any GAI-Tronics telephone equipment, please adhere to the following guidelines to
ensure the safety of all personnel:
•Do not install telephone wiring during a lightning storm.
•All telephone models must be properly connected to earth ground to protect personnel and to
minimize the effects of any electrostatic discharge (e.g., lightning). The Model 293AL-003, 294AL-
003, 297-003, and 298-003 Telephones each include a ground terminal. Please note proper grounding
does not eliminate the need for lightning protection for the telephone or the telephone system.
•Install a UL Listed lightning arrestor on any phone installed where the phone or phone cable is at
risk of being exposed to lightning strikes. The lightning arrestor must be installed as close to the
phone as possible to maximize the protection. It must not be installed within the enclosure supplied
with the phone. Please consult our Service Center at 800-492-1212 for further information.
•Do not install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•Do not touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•The Model 40404-045 Power Supply must be connected to an ac source within 4 feet of the
telephone. The ac source and power supply must be mounted in a dry location, such as a
GAI-Tronics stanchion.
General Installation Guidelines
GAI-Tronics S.M.A.R.T. phones are designed to operate on telephone lines as detailed in the Product
Overview section of this manual. The telephones are designed to operate with one telephone per line. If
telephones are operated in parallel or “party line configuration” you may experience sporadic phone
operation, difficulties with programming, or premature disconnection of calls. Additionally, if special
features, e.g. voice mail, call waiting, etc, are not disabled, the phone may not function.
Tamper-Resistant Hardware
All of the telephones described in this manual are vandal resistant. The front panel for each telephone
covered in this manual is attached to its enclosure with tamper-resistant screws. A GAI-Tronics Model
233 Tamper-Resistant Screwdriver (sold separately) is recommended for installing the tamper-resistant
screws.
Conduit Installation Details
GAI-Tronics recommends installing telephone lines in conduit to protect against accidental damage and
vandalism. To prevent moisture from entering the enclosure, we strongly recommend the following:
•Conduit should enter the enclosure from the bottom.
•Sealed fittings should be installed at all cable entry points.
•Silicone sealant or equivalent should be applied around and inside all conduit entries.

Setup
Hardware Configuration
The hardware configuration options are explained in detail in the following sections, and the necessary
jumper settings are identified to enable or disable each option. We recommend reading each section,
recording the selected options, making the necessary changes, and creating a record of your settings. See
Figure 7 on page 10 for the jumper locations.
Auto-answer Configuration
Factory Setting: Auto-answer feature enabled
The Auto-answer feature enables or disables the automatic answering of an incoming call, which allows
TMA to monitor the health of this phone via polling. When the Auto-answer feature is enabled, the
phone automatically answers the call and attempts to communicate with TMA. If the caller is not TMA,
then the phone rings its sounder to alert a user to lift the handset off-hook.
Enable: Insert the J14 jumper on pins 2 and 3.
Disable: Insert the J14 jumper on pins 1 and 2 (Do not use this setting except under the direction of
GAI-Tronics personnel.)
NOTE:The Auto-answer feature must be enabled during remote programming, and to allow the
GAI-Tronics Telephone Management Application PC to contact the phone.
Polarity Configuration
Factory Setting: Non-polarity sensitive
This telephone can be configured to be polarity or non-polarity sensitive. With the non-polarized setting,
the telephone regardless of tip and ring polarity. With the polarized setting, the telephone only operates
with the telephone line’s positive terminal connected to the tip. Use the Polarity Sensitive setting to allow
a line voltage reversal disconnect signal to disconnect the call.
Non-polarity Sensitive: Insert the J6 jumper on pins 2 and 3.
Polarity Sensitive: Insert the J6 jumper on pins 1 and 2.

Figure 7. Emergency Phone PCBA
Audio Level Adjustment
The speaker volume and microphone sensitivity are factory set to nominal levels that are acceptable for
most installations. However, some installations may require adjustments for the speaker and microphone.
Both the speaker and microphone adjustments are made using potentiometers on the emergency phone
PCBA. R106 is the speaker volume adjustment, and R88 is the microphone sensitivity adjustment. Refer
to Figure 7 for the potentiometer locations.
After making any adjustments to the audio levels, perform the automatic line level compensation as
detailed in the programming section of this manual.
When the phones leave the factory, the microphone potentiometer is set near minimum, and the speaker
pot is set to maximum. The speaker volume potentiometer (R106) provides 6 dB range of adjustment and
the microphone sensitivity potentiometer (R88) provides 12 dB range of adjustment.

PAGE 11 of 19
S.M.A.R.T. ADA-COMPLIANT EMERGENCY PHONES 42004-351H
\\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-351h.doc
02/05
Special care must be given to adjusting the speaker volume and microphone level. If one or both of the
levels are set too high, acoustic feedback (howling) can occur. If acoustic feedback occurs, we
recommend returning both potentiometers to the nominal factory settings and beginning the adjustment
again from this point.
Additionally, the acoustical characteristics of the emergency phones are different both when the front
panel is removed from the enclosure and when the front panel is tightly mounted in the enclosure. After
making any volume adjustments, we recommend mounting the front panel to the enclosure and again
testing the phone.
Auxiliary Output
Each telephone includes one isolated solid state switch capable of switching a maximum of 48 V dc, 125
mA or 28 VRMS ac, 80RMS mA. TB2 (OUT1) on the emergency phone PCBA provides the connections for
the auxiliary output. Refer to Figure 7 for the location of TB2.
The auxiliary output allows peripheral equipment, such as beacons, video cameras, and alarm generators,
to be activated when the EMERGENCY push button is pressed. The relay remains energized for the
duration of the emergency call.
In many applications, the auxiliary output is used to operate a GAI-Tronics Model 530FB/531A Beacon
(sold separately). For connection details, please refer to the Model 530FB/531A installation bulletin
included with the beacon. Information is also available at www.gai-tronics.com.

Programming
All S.M.A.R.T. Phone models are programmable. The phone settings are initially programmed during
manufacturing and testing. Factory default settings can be found in Table R-1. The following section
provides instructions for programming basic features needed to initially set up the phone from another
touch-tone phone.
We recommend using a handset phone exclusively when programming the S.M.A.R.T. phone remotely.
If a speakerphone is used for programming, the background noise can lead to incorrect settings. A cell
phone is also not recommended.
TMA is required to access many of the programmable features of the emergency telephones. For
programming using TMA, refer to the on-line help provided with the software, or contact the GAI-
Tronics Field Service Department.
Enter the Programming Mode
Read the entire programming section and carefully plan your programming before beginning the process.
For each setting that will be changed, we recommend writing down the key sequence from the Command
column of Table R-1, Basic Programming Commands. Having the programming information written
down allows you to enter the key sequence at a steady pace. This is important because the programming
sequence times out if there is a pause of more than 5 seconds during the programming sequence.
Complete the following steps to enter the programming sequence from a remote DTMF telephone:
1. Call the telephone to be programmed. (Do not use a cellular phone.)
2. Listen for a confirmation tone during ringing, which signals that the telephone has answered.
3. Press *** to enter the programming mode.
4. Wait two seconds.
5. Enter **0000 (0000 is the factory default maintenance PIN #.)
6. Enter *20. If the phone has successfully entered into the maintenance mode, the phone will respond
with six DTMF digits. If access to the maintenance mode is denied, the phone will respond with two
DTMF digits. If access is denied, repeat steps 5 and 6 to again request access.
7. Complete the desired programming. Refer to the Basic Programming Commands section for options.
8. Listen for a confirmation tone at the end of each programming sequence, which indicates the
programming change was accepted.
9. When finished programming, press *99 to exit the programming mode.

\\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-351h.doc
02/05
Basic Programming Commands
The following programming commands can be entered from any touch-tone telephone. Acceptance of
data transfer commands is indicated via a return code transmitted as an audible DTMF tone.
Auto-dial Memory
When the EMERGENCY button is pressed, the S.M.A.R.T. Phone dials a pre-programmed telephone
number (the primary number). If the call cannot connect (line busy, no answer), the phone will redial
using the first backup (roll-over) number. If again the call cannot connect, the phone will redial using the
second backup (roll-over) number. This sequence will continue until either the emergency call is
answered, or the programmed number of retries is reached.
Use the *1 command to program these three auto-dial numbers. The three auto-dial telephone numbers
are labeled as 11 (primary), 12 (first roll-over), and 13 (second roll-over). You can program these for
three different numbers, or set them to the same telephone number. Each auto-dial memory storage
location accommodates up to 24 characters.
To enter the auto-dial number into memory storage, or to change the number in storage, enter
*11<N><CHAR>#
*1 Data transfer command
1<N> Auto-dial memory location (N = 1, 2, or 3)
<CHAR>Telephone number to be stored in memory location (up to 24). Valid entries are
0-9 and the following 2-digit codes: *1 provides a 0.6-second pause in the
dialing sequence, *2 provides a DTMF #, and ** provides a DTMF *.
#End-of-string indicator
The command *1115551212#, for example, sets the primary number to 555-1212.
After each auto-dial memory storage location is successfully programmed, the phone returns a system-
generated DTMF check-digit.
If the phone is installed on a ring down telephone line, clear the first auto-dial memory using the
command *111#.

Automatic Line Level Compensation for Optimum Audio Performance
Every telephone line has different audio and electrical characteristics. To accommodate the varying lines,
the telephone has an automatic line level compensation function. When a telephone is first installed and
connected to a telephone line, we recommend initiating the automatic level compensation feature. The
automatic line level compensation is initiated in the programming mode with the *78 command, as
follows:
*780 Data transfer command
#End-of-string indicator
After the *78 command is successfully entered, the phone returns a system-generated DTMF check-digit.
To complete the automatic line level compensation, when programming is completed and the phone
placed back on-hook, the following process must be followed:
For single button emergency phones:
1. Remove the phone from the back box or enclosure.
2. Disconnect the emergency push button from J7, the “Emerg PB” socket on the phone PCBA.
3. Connect the emergency push button to J1, the “Call PB” socket on the phone PCBA. Press the
emergency push button. When dial tone is steady (with no volume variations), the process is
complete. Depending on the phone line and the duration dial tone, it may be necessary to repeat this
step one or more times.
4. Disconnect the emergency push button from J1, the “Call PB” socket on the phone PCBA.
5. Reconnect the emergency push button to J7, the “Emerg PB” socket on the phone PCBA.
6. Install the phone in the back box or enclosure.
For emergency phones with a call push button and keypad:
Press the call push button. When dial tone is steady (with no volume variations), the process is complete.
Depending on the phone line and the duration dial tone, it may be necessary to repeat this step one or
more times.

Call Time-out
The call time-out feature is used to limit the maximum duration of a call. The call time-out can be any
duration between one minute and 4 ½ hours. The duration is set in ½ second increments and the valid
range is from 120 to 32,400. To determine the value associated with a specific time duration, see the
example below.
*37 Data transfer command
<120~32400> Call duration (120 to 32400 ½ seconds) – See example below.
#End of string indicator
Example:
To determine what to enter for the call time-out duration, multiply the desired time limit, in minutes, by
120. For example, to determine the call duration entry for a call time-out of five (5) minutes, do the
following:
5 minutes ×120 = 600
To enter a call time-out duration of five (5) minutes, enter the character string *37600#.
When the call time-out duration has been successfully entered, the phone returns a system-generated
DTMF check-digit.

Maintenance
TMA users can schedule auto-dial maintenance calls to alert maintenance personnel of any unusual sensor
or fault conditions that exist. S.M.A.R.T. Phones can also be programmed to generate an auto-dial
maintenance call when certain sensor events are discovered. Access to the S.M.A.R.T. Phone’s
maintenance mode is restricted through the use of the maintenance access PIN. The maintenance access
PIN should be distributed only to trained maintenance personnel.
If your S.M.A.R.T. Phone requires service, contact your GAI-Tronics Regional Service Center for a
return authorization number (RA#). Equipment should be shipped prepaid to GAI-Tronics with a return
authorization number and a purchase order number. If the equipment is under warranty, repairs will be
made without charge. Please include a written explanation of all defects to assist our technicians in their
troubleshooting efforts.
Call 800-492-1212 inside the USA or 610-777-1374 outside the USA for help identifying the Regional
Service Center closest to you.
