The GAI-Tronics emergency 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
All of the above 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, Part No.
40404-045.

Americans with Disabilities Act (ADA) Functionality
Call Received Indicator Lamp
The CALL RECEIVED WHEN LIT lamp indicates to hearing-impaired individuals that the emergency call
has been answered. When the individual presses the emergency push button, the person receiving the call
(typically the security operator) presses the * DTMF button. The telephone detects the * DTMF signal
and illuminates the CALL RECEIVED WHEN LIT lamp.
Location Identification Code Dialing
The Location Identification Code feature enables security personnel to quickly and easily locate an
individual in trouble. When the individual presses the EMERGENCY push button, the person receiving the
call (typically the security operator) presses the * DTMF button. The telephone detects the * DTMF
signal and transmits a three-digit location identification code to identify which emergency telephone is
originating the call. This location code can be displayed on a DTMF decoder device (not supplied).
Disconnecting Calls
There are several methods to disconnect emergency telephone calls, including both manual and automatic
disconnect methods:
•To remotely disconnect an emergency call, the operator presses the #for a least 2 seconds or # #
twice within 2 seconds.

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-001, 294AL-
001, 297-001, and 298-001 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 in a
GAI-Tronics stanchion.
General Installation Guidelines
GAI-Tronics emergency 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
233-001 Tamper-Resistant Screwdriver (sold separately) is recommended for installing the tamper-
resistant screws.

Audio Level Adjustments
Speaker Volume Adjustments
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.
Please refer to Figure 13 for the potentiometer locations.
After making any adjustments to the audio levels, perform the automatic line level compensation as
detailed below.
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 a 6-dB range of adjustment
and the microphone sensitivity potentiometer (R88) provides a 12-dB range of adjustment.
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 phone with the front panel removed are
different than 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 testing the phone again.
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 resetting the automatic level compensation feature. The
automatic line level compensation feature is reset remotely (See the Remote Programming Section of this
manual) or locally with the #2316 command, as follows:
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.
4. On the PCBA, enable auto-answer by placing a jumper between pins 2 and 3 on J14 and disable
password protection by removing the jumper from J9.
5. Connect a keypad to J13. (Keypad, Part No. 51035-011, and Keypad Cable Assembly, Part No.
61504-048 are sold separately).
6. Press the EMERGENCY button. After you hear the dial tone, simultaneously press the 1and #keys.
After a confirmation tone is heard, enter the command #2316. To hang up the phone, press the
EMERGENCY button or wait for the phone to time out.
7. 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.

Programming
The telephone can be programmed remotely from another telephone, or locally at the emergency
telephone. To program the Model 294AL-001 and Model 298-001 locally, the front panel keypad can be
used. However, to program the Models 293-001, 293AL-001, and 297-001 locally, a Model 51035-011
Keypad must be connected to J13 on the telephone PCBA using the Model 51504-048 Keypad Cable
Assembly. Refer to Figure 8 for locations. Refer to the Local Programming section on page 17.
For remote programming, a touch-tone (DTMF) telephone connected to a separate central office (CO) or
private branch exchange (PBX) line is required. See the Remote Programming section below.
Remote Programming
The programming mode is accessed by dialing a four-digit programming password. Should it become
necessary to bypass the password protection feature, see the Password Disabled Programming section on
page 17.
Password Enabled Programming
1. Enable the password protection feature—insert the J9 jumper on pins 2 and 3.
2. Enable the auto-answer feature—insert the J14 jumper on pins 2 and 3.
3. Using a touch-tone telephone, call the emergency telephone. The emergency telephone automatically
answers the call and generates a splash tone followed by a success tone (single beep).
4. Dial the four-digit password. If the password has not been altered, dial 2468 (factory setting).
Otherwise, dial the preprogrammed user password. A success tone (single beep) is generated to
indicate the programming mode has been accessed.
NOTES:
•The telephone automatically times out if 20 seconds elapse between digit entries, or if an invalid
password is entered.
•If DTMF digits have not been dialed within three seconds of the call initiation, the telephone
remains off-hook and the programming mode is terminated.
•If the success tone is not generated, the telephone has failed to recognize the password.
Therefore, the telephone must then be programmed with the password disabled. See the
Password Disabled Programming section on page 17.
5. After you hear the success tone, begin entering the desired user-programmable parameters. Refer to
the Programming Sequences section on page 19. A success tone (single beep) is generated each time
a new parameter is accepted. An error tone (two beeps) is generated to indicate an error. If an error
tone is generated, verify the programming sequence, and enter the sequence again.
6. Terminate the programming by placing the touch-tone telephone on-hook.

For Models 294AL-001, and 298-001, the procedure is as follows:
1. Disable the password protection feature—insert the J9 jumper on pins 2 and 1.
2. Press the CALL push button. A dial tone is broadcast over the speaker. Simultaneously press 1and #
on the phone keypad. The telephone generates a splash tone followed by a success tone.
3. Enter the desired programmable parameters. See the Programming Sequences section below.
A success tone (single tone [DTMF #]) tone is generated each time a new parameter is accepted. An
error tone (double beep) is generated to indicate an error. If an error tone is generated, verify the
programming sequence is correct, and enter the sequence again.
NOTES:
•The telephone is off-hook during local programming. Therefore, programming should be
completed quickly to avoid any off-hook timeouts controlled by the CO or PBX.
•The telephone will automatically time out if 20 seconds elapse between digit entries.
4. Terminate the programming by pressing the CALL push button.
5. Enable the password protection feature—insert the J9 jumper on pins 3 and 2.

Programming Sequences
The programming information on the following pages explains the
programming options. The telephone is shipped from the factory
with a set of default parameters that are listed in the Programming
Table on page 24. A User Settings section has been provided in
the Programming Table for the user to record the selected
programming parameters.
It is recommended that the user read the sections that follow, record the desired parameters in the User
Settings section of the Programming Table, and then complete the programming using the instructions
from either the Remote Programming or the Local Programming section.
Dialing Options
The emergency telephones can be configured for either auto-dialing or ring-down operation. Select the
dialing option that fits your application. The dialing options are explained in detail in the following
sections.
Auto-dialing
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 back-up telephone number, the emergency phone will
automatically dial the second backup, or roll over, number. This sequence will continue until the
emergency call is answered, or the sequence is repeated three times for a total of 12 call attempts.
For the rollover feature to function properly, all three auto-dial memories must be programmed with valid
telephone numbers. The three auto-dial numbers can be the same or any combination of phone numbers.
If the phone is programmed with only one or two auto-dial numbers, the rollover operation will not
function and the numbers will only be dialed one time.
If an emergency phone is connected to a PBX, PABX, KSU, etc., telephone system, the emergency phone
can be programmed to access outside CO lines. Typically access to a CO line requires adding a digit (e.g.
9) to the auto-dial number. Also, a “pause” may be required in the auto-dial number. The pause typically
is required to wait for secondary (CO line) dial tone. See the example in the Emergency Button Auto-dial
Number 1 in the table below.
In addition to the pause, the emergency telephone has a programmable Primary Dial Tone Delay and
Secondary Dial Tone Delay. Both delays determine the amount of time the emergency phone will wait
before dialing the stored telephone number. The Secondary Dial Tone Delay can only be used if a “9” is
dialed to gain access to a CO line.
