2. Do not connect any power source other than speciﬁ ed to terminals +,

- nor install two power supplies in parallel to single input. Fire or

damage to the unit could result.

3. Do not connect any terminal on the unit to AC power line. Fire or

electric shock could result.

4. For power supply, use Aiphone power supply model or model speciﬁ ed

for use with system. If non-speciﬁ ed product is used, ﬁ re or malfunction

could result.

5. Voltage is applied to parts within the equipment. Do not touch any parts

that are not associated with the installation, wiring, or connection.

Electric shock could result.

6. If any abnormality (i.e., smoke, unusual smell or unusual noise) is

sensed from the unit, or the unit falls or gets broken, unplug the unit or

turn off the breaker immediately. Fire or electric shock could result.

CAUTION

(Negligence could result in injury to people or damage to

property.)

1. Do not install or make any wire terminations while power supply is

plugged in. It can cause electrical shock or damage to the unit.

2. Before turning on power, make sure wires are not crossed or shorted.

Fire or electric shock could result.

3. When mounting the unit on wall, install the unit in a convenient location,

but not where it could be jarred or bumped. Injury could result.

4. Do not install the unit in locations subject to frequent vibration or

impact. It may fall or tip over, resulting in damage to the unit or personal

injury.

5. Be sure to perform a call test or check the chime volume with the

handset on the hook. If you operate the hook switch with the handset on

your ear, a sudden call etc. may cause damage to your ear.

6. Do not place your ear close to the speaker during use as it could cause

hearing damage.

Precautions for mounting

1. Observe the following restrictions for mounting entrance stations.

• Do not mount the entrance station so that it faces obliquely upward. The

rain water may go inside and it may damage the unit.

• Do not block the bottom of entrance station by caulking.

2. Do not install the unit in any of the following locations. Fire, electric shock,

or unit trouble could result.

• Places under direct sunlight.

• Places near heating equipment or a boiler that varies in temperature.

• Places where dust, oil, chemicals or hydrogen sulﬁ de are present.

• Places where moisture and humidity extremes are present, such as

bathrooms, cellars, greenhouses, etc.

• Places where the temperature is quite low, such as inside a refrigerated

area or in front of an air conditioner.

• Places with steam or smoke (near heating or cooking surfaces).

• Places subject to sulfur, such as hot springs.

• Places near the shore or exposed to the direct sea breeze.

3. Do not install this unit in any of the following locations where lighting or

the ambient environment could impact the display on the video monitor due

to the characteristics of the door station's camera.

• Locations where is bright as the sky is shown widely behind the caller

• There is a white wall behind the caller

• Locations subject to direct sunlight or strong lighting

4. When using a ﬂ uorescent light that shines around the camera in the 50Hz

area, the screen colors may variously change as color rolling or ﬂ ickering.

Please block off the light or use the inverter ﬂ uorescent lamp.

5. For running cables, separate them for audio/video and door release and

keep them more than 10cm (3-15/16") away from each other.

6. When using an existing wiring, depending on the type of wiring, it may not

operate the system. Please check and change it in advance.

7. Do not use the impact driver for mounting. Damage to the unit could result.

General Precautions

1. Keep the intercom wires more than 30cm (12") away from AC 100-240V

wiring. AC induced noise and malfunction could result.

2. When installing and using the system, please consider the privacy and

portrait rights of users and visitors. Aiphone shall not be held responsible

for violation or privacy or other statutory rights. (The protection of privacy

and statutory rights is the responsibility of the customer.)

3. Install the units, which will not be operated, in an area that will be

accessible for future inspections, repairs, and maintenance.

4. Be sure to install an entrance station vertically. If it is installed horizontally,

rainwater may get into the unit causing a malfunction.

5. For maintenance or after-sales service, make sure to provide the setting

data to the customer.

6. Do not put an obstacle such as a foliage plant where monitoring is done by

a human body detection sensor.

Notices

• Do not install the unit close to an electrical appliance or water heater using

a dimmer or inverter, a remote controller of ﬂ oor heating, etc. Failure to do

so may generate a noise causing a malfunction of the unit.

• In areas where broadcasting station antennas are close by, intercom system

may be affected by radio frequency interference.

• When warm indoor air ﬂ ows into the unit, dew condensation may be caused

by a temperature difference between indoors and outdoors. It is

recommended to cover openings on the unit such as cable incoming holes

to avoid condensation.

• Using a mobile phone or professional-use radio equipment such as walkie-

talkie close to the system may cause a malfunction.

Prohibited Do not dismantle unit Keep unit away from water Be sure to follow the instruction

• For video entrance stations and video door stations, the

picture quality of the residential/tenant station monitor

is affected by the external light surrounding the built-in

camera. 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

• 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.

• Controls are located on the right side of the GT-2C-L/GT-2C, GT-2H-L/GT-2H, GT-1C7-L/GT-1C7 and GT-1M3-L/GT-1M3.

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 station.

• Entrance stations (all-in-one type) include a sensor. Do not place 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.

3 MOUNTING

To connect low voltage wires, either crimp them with a crimp sleeve or solder them, and then insulate by covering

with insulating tape.

[Crimping with a crimp sleeve]

Solid conductor

Solid

conductor

Keep the number of connections as

low as possible when wiring.

After connecting wires, make sure to check

for breaking or insufﬁ cient connection.

Especially when connecting a wire in the

middle of wiring, either crimp it with a crimp

sleeve or solder it, and then insulate it by

covering with an insulating tape.

Just twisting wires may cause poor connection,

or the surface of the wires may get oxidized to

cause a loose connection, leading to

malfunctioning or failure.

Stranded conductor

1. Line up solid and

stranded conductors,

and crimp them.

1. Twist the stranded

conductor around the

solid conductor at least

three times.

2. Bend the tip and solder it.

Make sure no lead wire

sticks out.

3. Overlap more than half of the

width and twist them at least

twice.

[Soldering]

2. Overlap more than

half of the width and

twist them at least

NOTES:

• If the lead wire with a connector is short, extend it using an interconnecting cable.

• Connectors have polarity, so pay attention and connect properly. If connected incorrectly, the

device won’t work.

The following is an example of a basic wiring diagram for the standard system.

* The wiring methods differ depending on the equipment used. Refer to sections 4-2 to 4-4 for the detailed wiring diagrams of entrance

stations, guard stations, and residential/tenant stations.

Each pair of wires should be in a separately jacketed cable (audio, video, and power wiring).

To prevent shorts, unused cables should be insulated.

NOTES:

• Do not use the unused terminals and ports for other purposes.

• In order to prevent miswiring, label both ends of each cable with the unit

and terminal names to which they are to be connected.

• For connecting other manufacturers’ products, refer to the instruction

manuals for those products.

* Refer to section 4-3 for detailed

connection diagrams.

* Refer to section 4-2 for detailed

connection diagrams.

How to set "UNIT Link-ID"

There are two methods for link setting.

By Hand-

shaking

The entrance/guard stations must be put into

programming mode and communication must

be established one-by-one with each resident

station. Either "Automatic setting" or "Manual

setting" is available.

By GT Setup

Tool

Every residential/tenant station must be set

with a unique residence UNIT Link-ID, as

shown below. Link establishment is performed

with the GT setup tool. Only the "Manual

setting" for UNIT Link-IDs is available. The

DIP swiches on SW2 must be set in advance.

1 SW1

Function Default

To terminate a residential/tenant

station, leave SW1 set to "A".

Otherwise, set to "B".

* Refer to section 4 "WIRING"

for details about the SW1 settings.

1 Set the tester for 250V AC or more.

2 Find the "hot" side of the AC outlet to be connected with a power plug.

2-1. Put one tester rod to the point that seems to be a grounding point.

2-2. Touch the other tester rod contact to one of the AC outlet slots to ﬁ nd the side where the tester needle swings.

The side where the tester needle swings is the "hot" side.

3 Find the proper grounding point.

3-1. With one tester rod put on the “hot” side, put the other to the point that seems to be a grounding point.

* If the needle swings to the power supply value for your country, it will be considered a proper grounding point.

If the needle does not reach the power supply value, it will not be considered a proper point.

3-2. Find the grounding point by repeating this step until the needle points to the proper value.

4 Connect the power supply ground terminal [ ] with the grounding point found in step 3.

When checking operation after system installation shows a malfunction in spite of no error in equipment terminal connections, check for the

following "grounding point" and "ground fault" in wiring.

Tools required: Analog tester

NOTES:

• A digital tester cannot make a precise reading.

• A megohmmeter cannot be used.

What is “ground fault”?

"Ground fault" means the state where internal copper wire is touching a metal part (ground) in the building because the coating on the wiring

of the intercom system is peeled off. This may cause the equipment to malfunction. Being in the ground fault state, the whole system will be

damaged seriously by a "power surge."

Inspection conditions:

Important

• Check that the power supply is grounded properly as described in 6-1 .

• Before starting inspection, make sure all control units (GT-BC, GT-VBC, GT-BCXB, GT-VBX), entrance station, and guard station are turned

on. (Only when the equipment is installed)

Inspection procedure:

1 Set the tester for around 50V DC.

2 Put one tester rod to the power supply ground terminal [ ]. If the power supply is not nearby, ﬁ nd a grounding point

referring to 6-1 .

3 With one tester rod put on the power supply ground terminal, put the other to the following terminals to be

inspected.

4 If the tester needle does not swing in step 3, it will be judged "no ground fault.".

* If the tester needle swings, there is a ground fault in wiring between the power supply and the inspected point.

(The same is true in the case where the needle swings reversely.)

Solution:

Divide the wiring into sections or trunk lines, identify the ground fault point, and remove the cause.
