Confidentiality Notice
This manual is provided solely as an operational, installation, and maintenance guide and contains sensitive
business and technical information that is confidential and proprietary to GAI-Tronics. GAI-Tronics
retains all intellectual property and other rights in or to the information contained herein, and such
information may only be used in connection with the operation of your GAI-Tronics product or system.
This manual may not be disclosed in any form, in whole or in part, directly or indirectly, to any third party.
Introduction
The GAI-Tronics Model 297 Emergency Telephone is designed for isolated or high-risk areas requiring
emergency communication equipment.
These telephones are constructed of
14-gauge, brushed stainless steel. This
rugged design prevents vandals from
damaging the telephone.
For increased visibility and security, the
telephones are equipped with an auxiliary
output to attach peripheral equipment, such
as beacons, video cameras, or alarms.
GAI-Tronics’ emergency telephones have
many user-programmable features and
options. The telephones are password
protected to ensure the integrity of all
programmed information.
The programming mode is accessed by
dialing the unit from any touch-tone
(DTMF) telephone and entering the
telephone’s password. Please refer to the
Programming Instructions section (page 8)
for a listing of all features.
To comply with the Americans with Disabilities Act (ADA), the Model 297 Emergency Telephone (shown
above) provides hearing-impaired individuals with a visual indication that the emergency call has been
answered. Also, the Braille tag provides vision-impaired individuals with a method of identifying the
functions of the telephone.

Operation
When an individual presses the EMERGENCY push button, a call is immediately made to a preprogrammed
number, typically a security office or a 911 emergency number. Personnel answering the emergency call,
takes the handset off-hook and presses *to acknowledge the call. The CALL RECEIVED WHEN LIT lamp
on the front panel will then illuminate, and half-duplex communication between the caller and the
emergency personnel can begin.
Acknowledgment of the call causes the telephone to perform two functions: illuminate the CALL RECEIVED
WHEN LIT lamp on the front panel and transmit a user-programmed three-digit location identification code.
Installation
The following sections provide information for installing the Model 297 Telephone.
SAFETY GUIDELINES
When installing any GAI-Tronics telephone equipment, please adhere to the following guidelines to ensure
the safety of all personnel:
•NEVER install telephone wiring during a lightning storm.
•NEVER install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•NEVER touch uninsulated telephone wires or terminals unless the telephone line has been disconnected
at the network interface.
•USE CAUTION when installing or modifying telephone lines.
INSTALLATION GUIDELINES
•GAI-Tronics’ emergency telephones are not designed to be installed in parallel or to be “party-lined.”
Any such installation can cause programming difficulties, premature disconnection of calls, or stations
that may not respond when activated. GAI-Tronics highly recommends that one telephone line (PBX
extension or CO line) be allocated for each unit.
•GAI-Tronics highly recommends that a telephone line surge suppressor be installed to guard against
lightning strikes. Please consult our Service Center at 800-523-4303 if further information is required.
•Sealed fittings should be installed at all cable entry points to prevent liquids from entering the unit.

PROGRAMMING THE SILENT MONITORING FEATURE
Emergency telephones emit a splash tone with every incoming call to alert individuals near the telephone to
answer the call. When the Silent Monitoring feature is enabled, the splash tone is eliminated, and
monitoring can begin without notifying individuals near the telephone.

NEW/OLD DTMF TRANSMITTER SELECTION
Emergency telephones have been manufactured with two different versions of the (U9) DTMF Transmitter.
Emergency telephones manufactured before 4/97 contain the older DTMF Transmitter (5087). All other
telephones contain the new DTMF Transmitter (5089). In most cases, a change to the factory settings will
not be necessary, however, if problems are experienced with dialing and/or status tones, identify the DTMF
Transmitter installed in U9 and program the unit accordingly.

AMERICANS WITH DISABILITIES ACT (ADA) PROGRAMMING
The ADA features provide the following three benefits:
Call Received Indicator Lamp Activation
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 will detect the *DTMF signal
and illuminate 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.
DTMF Call Disconnect
The DTMF Call Disconnect feature enables the person receiving the call (typically the security operator) to
disconnect the call on command. The security operator can disconnect the call by pressing #continuously
for two seconds or by pressing # twice within two seconds.
Feature Key
Sequence Description Default
ADA Options # 1 8 LThis option enables three features: call received

Auxiliary Output
The auxiliary output enables peripheral equipment (beacons, video cameras, alarms, and so on) to be
activated when the emergency push button is pressed. The auxiliary output is a solid state relay that
optically isolates the control voltage from the output contact. The auxiliary output is disabled when the
emergency push button is depressed.
See Figure 6and Figure 7for typical interconnection details of the GAI-Tronics 530A or 530FB Beacon
(sold separately) and the GAI-Tronics 531A Beacon (sold separately). See Figure 8for typical
interconnection details of relays to the auxiliary output. The relay design guidelines, the Auxiliary Output
Electrical Specifications, and the relay design examples have been provided to aid the user in selecting the
customer-supplied peripheral equipment.

AUXILIARY OUTPUT DESIGN GUIDELINES FOR RELAY ACTIVATION
•The auxiliary output is polarity sensitive (TB2-1 is positive and TB2-2 is negative).
CAUTION
Polarity reversals can damage the auxiliary output.
CAUTION
Use minimal torque on the terminals of TB2 to avoid damage.
•It is highly recommended to use a 24 V dc external voltage source.
•Transient suppression diodes must be used with inductive loads such as electromechanical relays.
