3. Before Installation
IMPORTANT
THESE UNITS MUST BE CONFIGURED BEFORE THEY ARE INSTALLED.
All units have identical settings as factory defaults, so each one must be individually
configured to give it a unique identity on the network. This may be difficult to do after
the units are installed.
IMPORTANT: After changing the IP address of the telephone you will need to browse
to the new IP address to access the configuration, instead of the default 192.168.1.2.
IMPORTANT: If DHCP is enabled, ensure that there is a suitable DHCP server available
on the network and that you have a means by which to discover the IP address of the
telephone allocated by the DHCP server. There is no other way to access a DHCP
enabled VoIP telephone over the network without being able to find the IP address
allocated by the DHCP server.
3.1. Opening the Unit
To open the case, undo the 4 security screws around the edge of the unit. These screws
are normally Torx type with a centre security pin.
The front section is fitted over the rear section and can be gently lifted clear.
Take care when separating the 2 sections – there are up to 4 cable sets between the
2 halves:
1. Induction loop audio (2 conductors)
2. DC power (2 conductors)
3. Earth cable
4. Ethernet cable (if already through one of the cable entries in the rear section).
These cables are deliberately short, but will allow the front section to sit to the left of the rear
for set-up purposes.
3.2. Initial Network set-up
Factory default settings are:
Item
Default setting
DHCP OFF
IP address 192.168.1.2
Net mask 255.255.255.0
Log in User Name user
Log in Password password
Serial port settings 115200 baud, 8 data bits, 1 stop bit, no
parity, no handshaking.
Hostname Each unit has a unique hostname (set to
the serial number of the main PCB)
These settings must be changed prior to installation: as a minimum the unit must either be
set to DHCP or assigned a unique static IP address.

400mm VoIP Help Point, 48V VoIP. 6
Refer to the VoIP configuration guide 502-20-0119-001 for full details on all settings.
The configuration guide is available from www.gai-tronics.org/support/voip-support/
To configure the unit it must first be powered, but note that the VoIP module itself can be
powered via PoE if required. External power is only necessary because of the induction loop
system.
As a quick guide the 2 most common methods of configuration are:
1. Make a direct network connection to the unit (for example using a crossover cable to
a laptop), then access the unit's web pages by browsing to 192.168.1.2, or
2. Make a serial connection to the unit, enter the login and password, then use CLI
commands such as:
IP SET DHCP ON, or
IP SET ADDRESS ...
IP SET MASK ...
etc.
The current IP settings can be displayed by entering IP SHOW ALL.
3.3. Site requirements
Having configured the unit for the intended network, ensure that the following are available
for installation:
1. Power supply: 48V dc @ 2A.
2. Ethernet connection – 10/100BaseT on CAT5/CAT5e UTP cable, the cable run is
normally limited to 95m.
3. This is normally a two-person installation, due to the size/weight of the unit and due
to the need to connect cables between the 2 sections.
4. Installation and dimensions
4.1. General
IMPORTANT
THIS PRODUCT CAN CONTAIN HAZARDOUS VOLTAGES. IT IS ESSENTIAL
THAT THE WATERPROOF SEAL IS PROPERLY MADE DURING INSTALLATION,
TO ENSURE THAT WATER CANNOT GET INTO THE ENCLOSURE. THE
INGRESS OF WATER CAN CAUSE ACCESSIBLE PARTS OF THE TELEPHONE
TO BECOME LIVE, AND THEREFORE MUST BE PREVENTED AT ALL COSTS.
All possible measures must be taken to ensure water, fluid or dust does not
contaminate the internal components of the unit whilst unpacking, preparing and
installing it in inclement weather conditions or by negligence.
Do not drill any additional holes in the casing. Make sure any unused cable
entry or mounting holes are properly sealed against water or dust ingress.
Failure to do so may result in an unsafe condition and will invalidate your
warranty.

2 x lower
1 x upper (used for aerial)
Positions are detailed on drawing
112-11-0081-001 appended to this manual.
4.3. Opening the Unit
To open the case, undo the 4 security screws around the edge of the unit. These
screws are normally Torx type with a centre security pin.
The front section is fitted over the rear section and can be gently lifted clear.
Take care when separating the 2 sections – there are 4 cable sets between the 2 halves:
5. Induction loop audio (2 conductors)
6. DC power (2 conductors)
7. Earth cable
8. Ethernet cable.
These cables are deliberately short, but will allow the front section to sit to the left of the rear
for set-up purposes if required.
4.4. Installation method
The Help Point is intended for vertical installation to a solid wall or suitable post as detailed
below.
1. Ensure the Help Point has been configured for the network as described in section
3.2.
2. Choose a suitable location for the Help Point, bearing in mind the weight of the unit,
and that the operating button(s) should normally be in the range 1200 – 1400mm
from the ground for ease of access by people in wheelchairs.
3. Mark the wall or surface with fixing centres as shown above. If necessary use the
rear section to help mark the centres. Do not use the rear section as a drilling
template.

400mm VoIP Help Point, 48V VoIP. 8
4. Select fixing screws or bolts appropriate to the type of wall or surface, suitable to
support the unit. Drill fixing holes to suit.
5. Separate the front and rear sections of the Help Point, taking care to disconnect
interconnecting cables as described in section 3.1.
6. Secure the rear section to the wall, making sure that the fixing holes are sealed to
prevent water ingress using nylon washers or other appropriate sealing methods.
7. Bring power and Ethernet cables into the unit through one or both of the cable entry
holes. Cables will normally be contained in conduit, but glands may also be used.
8. The power cable is terminated directly to the terminal block provided, and secured
using the cable restraint.
9. The ethernet cable should be left long enough to allow connection to the front section
(approximately 450mm from entry point) and terminated with an RJ45 plug.
10. Ensure that cable entries are sealed to prevent water ingress. If glands are used do
not over tighten – CAT5 UTP can be damaged by excess tightening. If only one cable
entry is used, the blanking plug fitted to the second position must be left in place.
11. Connect induction loop audio, dc power, ethernet and earth cables to the front
section of the case.
12. Apply power. The LED on the internal PSU should illuminate. After approximately 1
minute the red "heartbeat" LED inside the VoIP module should be visible flashing.
13. Fit the front section over the rear section and secure in place using the 4 security
screws.

5. Connections
5.1. DC Power connections
Connect a 48V DC power supply to the terminal block as shown
on the connection label.
If a 48V power supply is not available, GAI-Tronics can supply a
suitable unit, see spare parts (section 8).
One power supply cannot supply more than one PHP400 - a
separate, isolated supply must be provided for each unit..
Cabling from the 48V supply to each PHP400 must be sufficient
to provide the required current (2A) without causing a significant
voltage drop over the required distance.
The fuse must always be replaced by the correct type, ie 3.15A
T (20x5mm).
5.2. IMPORTANT SAFETY INFORMATION
Please pay particular attention to the following points if hazardous voltages (>48V) are
to be connected to either of the control outputs:
The circuits that the relay contacts are connected to must be of the same type, i.e. Both
mains, both SELV or both TNV. It is not permissible to mix the types of circuit
connected to these relays.
It is acceptable to connect mains circuits in the frequency range 45 to 65 Hz to these
relays.
For currents up to 3 Amps, the minimum conductor cross sectional area must be 0.75
mm
2
(19awg) for flexible cords, or 1mm
2
(18awg) for other cables. For currents up to 10
Amps, the minimum conductor cross sectional area must be 1 mm
2
(18awg) for flexible
cords, or 1.5mm
2
(16awg) for other cables.
Circuits connected to these relays must be protected against over-current and short
circuit by a suitable method, for example a fuse or circuit breaker rated at less than or
equal to the relay contact rating.
The use of an isolated supply or an RCD is recommended for these circuits.
Cables or cords used must be insulated and and have an overall insulated outer sheath
covering both conductors. They must be appropriately rated and certified. Examples of
suitable ratings for PVC cords are IEC 60227 designation H05 VV-F or H05 VV-F2, or
for rubber insulated cords, IEC 60245 designation H05 RR-F
Always ensure that sufficient clearance is maintained between hazardous
voltages and any accessible conductive parts.

Connection types and ratings:
•LAN connection - RJ45 on Cat5 or Cat5e UTP cable
•All other connections - 0.14mm² to 2.5mm² (26 to 14awg) for rigid/solid cables,
0.14mm² to 1.5mm² (26 to 16awg) for flexible/stranded cable.
Refer to safety information in section 5.2
Output 1 - rating 2A at 250Vac, 2A at 30Vdc
Output 2 - 3A at 250Vac, 1A at 24Vdc
(Note: for Output 1, a continuous current of 2A will cause a 22°C temperature rise to the
PCB area close to the terminals after 10mins. If the current is below 1A this
temperature rise will be less than 5°C. Output 2 will not give any significant temperature
rise up to its rated current of 3A)
Power Connection - 48Vdc from external supply, connected via terminal block in rear
section. Note that the VoIP module itself requires only 100mA from the 48V supply –
the majority of the power is required by the induction loop amplifier fed by the 48-12V
DC-DC converter.
Control inputs - for connection to voltage free contacts only. Internal pull-up resistor
source current = 300uA. These inputs form part of a SELV circuit and precautions must
be taken to prevent hazardous voltages being applied to these circuits

6. Cleaning
Recommended cleaning methods are outlined below:
6.1. Normal Cleaning
For normal cleaning we recommend "Virosol", manufactured by Clover products.
Carefully follow manufacturer's instructions for storage, handling and use.
6.2. Stainless Steel Push-buttons
Stainless steel push-buttons, where fitted, should be cleaned regularly especially if the
Help Point is in a marine environment. The stainless steel may show signs of
discolouration or rust – this will not damage the buttons or impair their performance but
may look unsightly and can be cleaned off using normal cleaning agents as above. In
extreme cases a mild abrasive may be necessary.

400mm VoIP Help Point, 48V VoIP. 12
6.3. Graffiti
For graffiti, paint and ink we recommend the use of 3M GR2 graffiti stain remover.
CAUTION: This is a very aggressive chemical. Pay close attention to the manufacturer's
recommendations for storage, handling and use.
6.4. Anti-Graffiti Coating
Where polyurethane anti-graffiti coating or paint has been specified (as an option), it
can be cleaned using Methylated Spirits or Methyl Isobutyl Ketone. Other cleaners can
be used but should be tested on a small area first.
