PRECAUTIONS
General Prohibitions
Prohibition to Dismantle the Unit
WARNING
(Negligence could result in death or serious injury.)
1. The units must be installed and wired by a qualified technician. Having installation
performed by an unqualified technician could result in electric shock.
2. Do not dismantle or alter the unit. Fire or electric shock could result.
3. Do not connect non-specified power sources to the +, - terminals. Also, do not install
two power supplies in parallel to a single input. Fire, damage, or system malfunction
could result.
4. Keep the unit away from water or any other liquid. Fire or electric shock could result.
5. Do not remove the power supply plug with wet hands. Electric shock could result.
6. Do not put any metal or paper into the unit through the openings. Fire, electric shock,
or unit trouble could result.
7. High voltage is present internally. Do not open the case. Electric shock could result.
8. Do not connect any terminal on the unit to an AC power line. Fire or electric shock
could result.
CAUTION
(Negligence could result in injury to people or damage to
1. Before turning on power, make sure wires are not crossed or shorted. If not, fire or
electric shock could result.
2. When performing call tests or checking the chime volume or call volume, make sure the
handset is placed on the main unit. Failure to do so may result in injury to the ears.
3. Do not install or make any wire terminations while the power supply is turned on. This
can cause electrical shock or damage to the unit.
4. Do not place (install) the unit in locations subject to frequent vibration or impact. Injury or damage could result if the unit falls.
5. When mounting the unit on a wall, install the unit in a convenient location, but not
where it could be jarred or bumped. Injury could result.
6. Do not alter or change the wall-mounting area of the unit.
This could result in injury if the unit falls or if something comes in contact with the unit.
7. Do not apply force to the television monitor. Damage or injury could result.
8. If the LCD is punctured, do not allow skin contact with the liquid crystal inside. Inflammation could result. If liquid crystal is ingested, immediately gargle with water and
seek medical attention. If contact with the eyes or skin occurs, clean with pure water for
at least 15 minutes and seek medical attention.
9. When washing the wall surface with high-pressure water, make sure water does not get
on the entrance station. Fire or electric shock could result.
10. Do not install the unit in any of the following locations. Fire, electric shock, or unit
trouble could result.
* Places under direct sunlight or places near heating equipment that varies in tempera-
ture.
* Places subject to dust, oil, chemicals, etc.
* Places subject to moisture and humidity extremes, such as bathrooms, cellars, green-
houses, etc.
* Places where the temperature is quite low, such
of an air conditioner.
* Places subject to steam or smoke (near heating or cooking surfaces).
* Where noise generating devices such as dimmer switches or inverter electrical appli-
ances are close by.
11. Do not put anything on or cover the unit with cloth, etc. Fire or unit trouble could result.
12. For power supply, use Aiphone power supply model or model specified for use with
system. If non-specified product is used, fire or malfunction could result.

Prohibition on Subjecting the Unit to Water
General Precautions
General Precautions
1. All units, except for the entrance station, are designed for indoor use only. Do not use
outdoors.
2. The unit turns inoperative during power failure.
3. In areas where broadcasting station antennas are close by, intercom
fected by radio frequency interference.
4. Keep the intercom wires at least 30 cm away from strong electrical wiring (AC 100-240 V)
including, in particular, wiring for inverter electrical appliances. Noise and malfunction
could result.
5. Keep the unit more than 1 m away from radio or TV set.
6. If a strong light shines on the main unit screen, the picture will turn white or only s
ettes will be visible. But this is not a unit malfunction.
7. As to other manufacturer's devices (such as sensor, detectors, door releases) used with this
system, comply with the Specifications and Warranty conditions that the manufacturers or
venders present.
8. The LCD panel is manufactured with very high precision techniques. Please be aware of
this in advance.
9. The sensor of an entrance st

SYSTEM CONFIGURATIONS
Standard system configuration1-1
This system is constructed with a 2-line communication system and a 2-line video system and requires minimal work for installation. The system is
constructed with video trunk lines consisting of a maximum of 6 trunks from the video bus control system and communication trunk lines that use a
distribution point from a bus control unit. In addition, systems with audio only can be configured.

The GT-VBC can be used as an extension adaptor as well (2
units per trunk line).
To do so, set the setting switch (SW2) to "EXP".
Use the unit as an extension adaptor in expanded systems.
Even if two units are used as extension adaptors (SW2:
EXP), the wiring distance to the farthest residential station
from the GT-VBC (SW2: STD) or GT-VBX is limited to 300 m.

MOUNTING
3-1
• For video entrance stations and video door stations, the picture quality of residential station monitoring is affected by the nature of the external light
from above and the surrounding area of the built-in cameras, so do not install these stations in the types of locations shown below.
• Locations exposed to direct sunlight
• Locations under street lights or door lights
• Other locations exposed to strong light
• Install master monitor stations and sub master monitor stations in places where the screen is not exposed to direct sunlight.
• A switch
Allow open space of 5 cm (2").
• At least 15 cm (6") of vertical open space from the center of the mounting bracket is needed for mounting the master monitor station or sub master
monitor station.
• Entrance stations (Integrated type) include a sensor. Do not places objects such as plants or trees in places monitored by the sensor.
Also, placing the unit in bright sunlit areas may prevent the sensor from working properly.
Mounting locations
is located on the right side of the GT-2C-L/GT-2C, GT-2H-L/GT-2H, and GT-1C-L/GT-1C.

• Use PE (polyethylene)-insulated PVC jacket cable.
Parallel or jacketed 2-conductor, mid-capacitance non-shielded cable is recommended.
• Never use individual conductors, twisted pair cable or coaxial cable.
Appropriate cable
(x2)
Weak electrical current line connection
Length is 8 mm for the GT-DA-L/GT-DA, GT-DMV/GT-DM, GT-2C-L/GT-2C,
GT-2H-L/GT-2H, GT-1C-L/GT-1C, GT-BCX, GT-VBX, and GTW-LC; and 9 mm
for other units.
Insert the wire into the direct terminal. If it is difficult to insert the wire, insert it while
pressing the release button.

• For the useable modules, see 2-1.
• The GT-SW can have up to 6 modules.
To connect 7 or more modules or to increase the light intensity, please con-
tact Aiphone.
4 Mount each module panel to the front frame.
• Mount the panels from behind the front frame.
• Insert the holders into the slots on both sides.
(With the GT-4F, mount the module panels so that they catch on the tabs in
order from top to bottom.)
