General Prohibitions
General Precautions
Prohibition to Dismantle the Unit
Prohibition on Subjecting the Unit to Water
WARNING
(Negligence could result in death or serious injury to people)
1. The unit must be installed and wired by a qualified technician.
2. Do not dismantle or alter the unit. Fire or electric shock could result.
3. Do not connect any non-specified power source to the +, - terminals, and do not
install two power supplies in parallel to a single input. Fire, damage to the unit,
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 plug or unplug with wet hands. Electric shock could result.
6. Do not put any metal or paper into the unit through the openings. Fire or
electric shock could result.
7. Do not put high pressure on the video-monitor surface. If fractured, injury
could result.
8. High voltage is present internally. Do not open the case. Electric shock could
result.
CAUTION
(Negligence could result in injury to people or damage to property)
1. Make sure wires are connected properly before plugging the power supply into
an electrical outlet.
2. Do not manually hold down hook switch while testing and verifying chime or
call tone volume. The chime tone is very loud in earpiece,and could cause
hearing damage.
3. Do not install or make any wire terminations while power supply is plugged in.
It can cause electrical shock or damage to the unit.
4. Do not install the unit in a location subject to constant vibration or impact. If
dropped, injury or unit damage could result.
5. 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.
6. Do not alter or change wall-mounting of the unit. If dropped, it can cause injury.
7. Before turning on power, make sure wires are not crossed or shorted. Fire or
electric shock could result.
8. If LCD is punctured, do not allow contact with the liquid crystal inside.
Inflammation could result. If necessary, gargle your mouth and clean your eyes
or skin with clear water for at least 15 minutes, and consult your doctor.
9. When cleaning outer surface with high-pressure water, be sure that the entrance
station will not be subjected to direct water pressure. Damage to the unit could
result.
10. To avoid system malfunction, do not install the unit in places;
1. high or extreme cold temperature,
2. subject to moisture or humidity extremes,
3. environmental conditions: dust, oil, chemicals, salt, etc.,
4. constant vibration or impact, and 5. steam or smoke.
11. Do not put anything on or cover the unit with cloth, etc. Fire or unit trouble
could result.
12. For DC powered systems, use Aiphone power supply model specified with
system. If non-specified product is used, fire or malfunction could result.
GENERAL PRECAUTIONS
1. All the units, except for entrance station, is designed for indoor use only. Do
not use outdoors.
2. The unit will be inoperative during a power outage.
3. In areas where broadcasting station antennas are close by, the intercom system
may be affected by radio frequency interference.
4. Keep the intercom wires more than 12 inches (30 cm) away from AC
100~240V wiring. AC induced noise and/or unit malfunction could result.
5. Keep the unit more than 1 m away from Radio or TV set.
6. When strong light comes in on the unit's screen, the image looks white or
silhouetted. But this is not a unit trouble.

Mounting the Entrance Station (1)
[1] Back box
[2] Joint pipe
[3] Back box assembly dimensions
[4] Special screwdriver (enclosed with GH-BC)
1. Mounting the back box
• Make a hole for the cable.
• Use the joint pipe to assemble the back box.
• Make sure the back box is mounted level.
• Mount the camera and GH-NS module at eye-level for the
average height of an adult.
Do not mount the back box on a surface that is recessed by 15
mm (1/2") or more from the external surface of the wall.
2. Set up the modules.
• For information on what modules can be used, see 2-1 and 2-2.
6 GH-SW modules can be used. If you would like to connect 7
modules or more, please contact Aiphone.
3. Mount each module panel to the front frame.
• Mount the panels from behind the front frame.
•
Insert the notch into the slots on both sides and slide it downward.

Mounting the Entrance Station (3)
1. Example of interconnection of modules.
2. Use GF-C to connect to the name scrolling module.
3. To position the speech module in the center row, run GF-C
through the joint pipe in advance.
Mounting the Entrance Station (2)
1. Remove the terminal cover.
2. From the speech module to the next module, insert the attached
connector into the socket. Make sure to run the cable under the
terminal cover for protection.
3. Connect the connectors between the modules with cables.
4. Run the connection cable through the joint pipe (which you
should have made open in advance) and connect CN1 of GHSW to the next row.
5. Put back the terminal cover.

• Lift up the rubber cap.
• Press the program switch once. Use any long thin tool, such as
a fine screwdriver.
• The In-Use LED will blink for approximately 15 seconds for
entrance stations with GH-SW and between approximately 6 to
15 seconds for entrance stations with GH-NS.
4. Once the In-Use LED is lit solid, press the talk button of the
first residential station. The corresponding communication
channel will be established.
5. For GH-SW, press the (corresponding) call button and release

in steps 4 through 6. An electronic beep will be emitted twice. An
electronic sound will be emitted three times for a third residential
station and four times for a fourth residential station.
7. Correcting or changing the settings
• Press and hold down the call button of GH-SW or GH-NS until

• Replace the cap.
9. Checking the programming
• Pressing the program switch for 5 seconds or more will light up
the In-Use LED.

when the programming was successful. If the programming was
unsuccessful, an alarm beep will be emitted.
• For GH-NS, use the arrow keys or 10-key to select the room
and press the call button. An electronic sound will be emitted
once when the programming was successful. If the
programming was unsuccessful, an alarm sound will be emitted.
• Press the programming switch to end the check.
If power supply is interrupted during programming, the
programmed information might be lost. In such cases, retry
the programming again from the beginning.

simultaneously.) An electronic beep will be emitted once.
2.
If you attempt to setup a fifth residential station when four
residential stations have already been established, an alarm
beep will be emitted. To cancel the communication link,
