2. FCC REQUIREMENTS
(1) The AI-900 complies with FCC Rules, Part 68. On this equipment is a label which contains, among other
information, the FCC Part 68 registration number.
(2) The ringer equivalence number (REN) is used to determine the quality of devices which may be
connected to the telephone line. Excessive RENs on the telephone line may result in the devices not
ringing in response to an incoming call. In most, but not all areas, the sum of RENs should not exceed five
(5.0). To be certain of the number of devices that may be connected to a line, as determined by the total
RENs, contact the local telephone company.
Note: RENs are associated with loop-start and ground-start ports. It is not used for E&M and digital ports.
The REN assigned to the AI-900 is 0.4. If requested, this information must be given to the
telephone company.
(3) In the event of equipment malfunction, all repairs should be performed by AIPHONE CORPORATION or
an authorized agent. It is the responsibility of users requiring service to report the need for service to
AIPHONE CORPORATION or to one of our authorized agents. Service can be facilitated through our
office at:
AIPHONE CORPORATION
1700-130th Ave., N.E.
Bellevue, Washington 98009
Phone (425) 455-0510
The telephone company can ask you to disconnect the equipment from the network until the problem is
corrected or until you are sure that the equipment is not malfunctioning.
(4) If the AI-900 disrupts the telephone network, the telephone company can discontinue your service
temporarily. If possible, the telephone company will notify you in advance. If advance notice is not
practical, they will notify you as soon as possible. You are also informed of your right to file a complaint
with the FCC.
(5) The telephone company can make changes in its facilities, equipment, operations, or procedures that can
affect the operation of your equipment. If they do, you should be notified in advance so you have an
opportunity to maintain uninterrupted telephone service.
(6) While the AI-900 is fully compliant with FCC rules and regulations, it is recommended that an alternating
current (ac) surge arrestor of the form and capability suitable for the model purchased be installed in the
ac outlet to which the AIPHONE CORPORATION products are connected. Consult with your distributor as
to the surge protector requirements for your equipment.
(7) The FCC rules require that the following Affidavit be completed by the installer and forwarded to the local
exchange carrier, whenever digital terminal equipment without encoded analog content and billing
protection is used to transmit digital signals containing encoded analog content, which are intended for
eventual conversion into Voiceband analog signals and retransmitted on the network.
(8) The AI-900 has been tested and comply with the limits for a class A digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction manual,
can cause harmful interference to radio communications. Operation of this equipment in a residential area
is likely to cause harmful interference, in which case the user will be required to correct the interference in
the user's expense.
CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY AIPHONE CORPORATION
COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT.

3. INDUSTRY CANADA REQUIREMENTS
(1) ''NOTICE: This equipment meets the applicable Industry Canada Terminal Equipment Technical
Specifications.
This is confirmed by the registration number. The abbreviation, IC, before the registration number signifies
that registration was performed based on a Declaration of Conformity indicating that Industry Canada
technical specifications were met.
It does not imply that Industry Canada approved the equipment."
(2) ''NOTICE: The Ringer Equivalence Number (REN) for this terminal equipment is 0.4.
The REN assigned to each terminal equipment provides an indication of the maximum number of
terminals allowed to be connected to a telephone interface.
The termination on an interface may consist of any combination of devices subject only to the requirement
that the sum of the Ringer Equivalence Numbers of all the devices does not exceed five.''
(3) "The abbreviation, IC, before the registration number signifies that registration was performed based on a
Declaration of Conformity indicating that Industry Canada technical specifications were met. It does not
imply that Industry Canada approved the equipment.
(4) This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.

4. GENERAL DESCRIPTION
The AI-900 Security System is a voice communication system that permits calls to be quickly and easily
made - even in emergency situations - with the touch of single button. The system can record conversations,
and features external equipment sync output and operation log output. These features combine to make the
AI-900 an ideal system for voice security applications.
5. FEATURES

• Rack- or wall-mountable exchange.
• Up to 4 master stations (or commercial telephone sets) and 64 substations can be connected per exchange.
• Up to 2 outside telephone (C/O) lines can be connected per exchange.
• Station paging (by means of the substation speaker) and external paging functions.
• External sound source distribution capability.
• Up to 19 paging zones can be established.
• Emergency Paging function.
• By connecting an external recording device, the conversations at the master station (or telephone set) and
at the outside line telephone can be recorded.
• Exchange operating log can be transmitted to a PC.
• Tie-line possible for up to 16 exchanges.
• 24 V DC input for connection of backup power supply.
• Manual/Automatic Call Forwarding, Conference, Scan Monitor functions.
6. INSTALLATION PRECAUTIONS
• To prevent the unit's failure, be sure to switch off its power when inserting or removing the card.
• When mounting each card, fully insert it into the Main Frame. After all cards are mounted, secure them with
the card fixing bracket.
• When the unit gets dirty with dust or oil, wipe down with a soft, dry cloth. Never use a chemically-treated
cleaning cloth or volatile liquids, such as benzine and thinner, because the unit's plastic parts may be
deformed or its finish discolored.
• All units except the AI-RS170 and AI-RS180 Substations are designed exclusively for indoor use.
Do not install them outdoors.
• The whole system will not operate without power supply.
• In areas where broadcasting stations are close by, the system operation may be affected by radio frequency
interference.
• Keep DC wiring at least 30 cm away from AC wiring. Otherwise, the system may malfunction.

Replace only with the same or equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer's instructions.
CAUTION
Danger d'explosion lorsque la batterie n'est pas remplacée correctement.
Remplacer uniquement avec des batteries identiques ou d'un type équivalent.
ATTENTION
Battery replacement
As the battery life is rated at about 4 years, replace it with a new one every 4 years.
Follow the replacement procedure below.
Step 1. Switch the Main Frame (AI-900MF) power off.
Step 2. Remove all installed cards.
Step 3. Switch the AI-900MF power on.
Step 4. Replace the battery.

12.5.2. External recording device and AI-900AL connection
An external recording device can be connected to each telephone line.
[Connection]
To connect the external recording device, use a twisted pair cable for voice output, and a twisted pair cable for
control output. The voice output is 0 dB* and of unbalanced type. The control output is an open collector
output of 20 mA, 24 V DC max. Connect as shown below.

14. SPEECH AND FUNCTION TESTS
Using installed equipment, perform both speech and function tests after system programming completion.
14.1. Speech Test
(1) Calls from the substation
• Call the Master Station (telephone) from each substation to check to be sure that a conversation is possible.
Also, check to confirm that the master station (telephone) registered in system programming is correctly
called.
• Check to be sure that the calling substation number (name) is correctly displayed on the Master Station.
(2) Calls from the master station
• Call the substation and Master Station from each Master Station to check to be sure that a conversation is
possible.
• Check to confirm that the designated station is correctly called.
14.2. Function Test
Check each function registered in system programming for correct operation.
For each function's operation, refer to the "AI-900 OPERATING INSTRUCTIONS."
