1. Safety and Care Information
▲
The safety of the user/installer relies on the isolation of the telephone
network and not on the earthing of the case
▲
Please read these instruction
s thoroughly before starting installation.
These products must be installed by competent personnel familiar with
telephone installation.
▲
Telephone network voltages can be hazardous. Take adequate
precautions when opening the case or installing. If in doubt, disconnect
the telephone line elsewhere before accessing the line connections.
▲
For increased protection against lightning transients, attach a local
earth to the main terminal block (see section 6.1)

This manual describes Help Point and VR (Vandal Resistant) ranges of
hands-free telephone products. These units offer high degrees of resistance
to weather and abuse, having only a microphone, speaker and one or more
metal buttons mounted on a flat, metal faceplate, in place of a traditional
handset and keypad. Main features include:
•4mm thick aluminium faceplate
•Waterproof speaker, protected by stainless steel mesh

VR & Help Point 5
•Sensitive microphone, protected by semi porous membrane and
aluminium grille
•Stainless steel auto-dial button(s)

2.1. Changes from previous versions
This manual describes an updated range of products introduced in December
2007. For those familiar with GAI-Tronics’ products, the list of new or
changed features is as follows:
•New terminal layout (section 6).
•Increased lightning protection (section 10).
•Compliance with railway EMC standards (section 10)
•Optional additional relay outputs and logic inputs (section 6.3 & 6.4)
•Optional isolated input for power supply (section 6.2)
•Improved clear-down mechanisms (section 3.3)
•RoHS compliant
For the full list of product features, please see the specifications in section 10.
3. Operation / Testing
Please note that, following its initial connection to the line (ie first installation), there
may be a delay of up to 30s before the telephone can make an outgoing call.
3.1. Making a Call
To make a call, press the required button and wait for connection. The unit
will seize the line and then automatically dial the pre-programmed number.
3.2. Answering calls
To receive a call, press any button when ringing is heard.

6 VR & Help Point
3.3. Ending the Call
There is no direct way for a user to end a call from the unit. The unit will close
down and release the line on receipt of the following signals, usually when the
remote party clears:
•Line polarity reversal
•A line break (sometimes referred to as a “k break”).
•Receipt of exchange call progress tones (see section 10 for specification)
3.4. Call timer
The phone has a programmable call timer that can limit the maximum call
duration.
When ON, the timer forces the phone back off line after the preset time. This
prevents the line remaining tied if the neither party ends the call. The timer is
factory-set to 7mins by default, but can be set to any value (up to 2¾hrs) or
disabled. See section 7.2.1.
3.5. Semi Duplex Operation
The Help Point is semi duplex, with automated switching between transmit
and receive depending on which signal is the stronger. It therefore requires
an adequate signal level to be able to switch into receive mode. This level
may vary according to ambient noise levels at the Help Point, but we would
recommend ensuring that the incoming signal level received at the Help point
is at least -35dBm.
This level may have to increase if the ambient noise level at the Help point is
high, and in any event correct operation cannot be guaranteed in ambient
noise levels exceeding 80dBA.
Semi duplex operation can also be affected if the impedance of the telephone
line differs significantly from the pan-European standard – see section 10.
4. SMART features
This family of products has a wide range of intelligent features including:
•Monitoring of faults and health status
•Remote programming of auto-dial numbers and configuration parameters
•Alternate day / night autodial numbers
•Call logs for calls made to and from the telephones
1

Called Party Answered signalling (CPA), ie a reversal of line polarity when an
outgoing call is answered, is required to ensure accurate recognition of call
connection and answer delay times. CPA is a telephone line service and may not
be available from all telecom service providers.

VR & Help Point 7
These features are all available over standard, 2 wire telephone lines with no
external power required at the phone.
To use these features, GAI-Tronics provide a Telephone Management
Application (TMA) available separately, see section 7.3.
5. Installation
5.1. General
IMPORTANT
All possible measures must be taken to ensure water, fluid or dust
does not contaminate the internal components of the telephone whilst
unpacking, preparing and installing the telephone in inclement weather
conditions or by negligence.
Failure to do so may invalidate your warranty.
These telephones are supplied without connection leads – cabling to the
telephone network must be supplied and installed by the installer. Because of
this, extra precautions must be observed: installers must ensure that they
have the permission of the owner of the PABX or telephone network to which
the telephone is to be connected, and that installation is carried out by
competent personnel. Where the telephone faceplate is mounted into an
enclosure or recess other than the standard GAI-Tronics backbox, then
additional care must be taken that wiring and proximity to conducting surfaces
complies with the requirements of the R&TTE Directive - 1999/5/EC.
Contact GAI-Tronics if installation service is required.
From a mounting and installation point of view, VR and Help Point products
are identical.

5.2. Wall/Pole Mounting
When wall or pole mounted, VR and Help Point units must be fitted inside a
dedicated rear enclosure.
Before mounting the telephone, check the cable routing and requirements. If
glands are required, fit them to the case as follows:
1. Remove the RED blanking plug leaving the other (usually BLACK) in
place.
Only fit a second gland if a separate cable is required to the phone (for
example for an additional hook contact).
2. Select the appropriate sized gland:
Use the smaller gland for cables
diameters 4 - 7mm.
Use the larger gland for cable
diameters 8 - 13mm.
3. From the outside of the case, insert
the selected gland into the threaded
cable entry hole and tighten, so that
its sealing washer is compressed
against the enclosure surface.
4. Ensure that both cable entries are sealed with either a gland or a black
blanking plug as described.
5. Proceed with chosen mounting method below

VR & Help Point 9
5.2.1 Wall mounting
1. Using a suitable tool, punch out 4 holes in the rear enclosure, taking
care not to damage or dislodge the plastic bushes. Only four of the
eight holes are required - the outer ones are recommended. The
inner holes are provided to be compatible with older-style mounting
posts, and should be left intact if not used. If the inner holes are
used they must be fitted with the supplied plastic bushes.
WARNING:.Your warranty will be invalidated if :-
1. Any fixing hole made in the rear enclosure is left unused.
2. Any additional holes are drilled into the telephone enclosure.
3. Plastic bushes are not used on all fixing holes.
2. Mark the wall with hole centres based on the dimensions shown
(145 x 270mm). If necessary offer the rear enclosure up to the wall
to check alignment. Do not use the enclosure as a template for
drilling.
3. Drill holes in the wall on the marked positions. Select appropriate
screws, wall plugs etc., for the type of wall, bearing in mind that the
weight of the complete phone is around 5kg.
IMPORTANT:USE ONLY countersunk-headed fixing screws. Check
that screws seat properly in the plastic bushes to ensure a
watertight seal. Do not use excessive tightening force, as this may
crack the case.
4. Ensure that all four plastic flanged bushes are in place and the rear
enclosure is screwed tightly to the surface to prevent any water
ingress through the punched holes.
5. Complete the installation by making the appropriate connections
(section 6) and re-fitting the face plate.

5.2.2 Pole mounting
Kit No 100-02-0208-001
This accessory is for mounting GAI-Tronics telephones on to the side of
round poles of 100mm to 200mm diameter, or on to square or
rectangular section uprights of 100mm to 150mm across the mounting
surface.
NOTE:
Banding straps (large scale worm-drive clamps) are not included in this
kit and must be obtained separately. For details of where banding can
be obtained, refer to GAI-Tronics.
1. Using a suitable tool, punch out the 4 outer holes in the rear
enclosure, taking care not to damage or dislodge the plastic
bushes.
2. Attach the pole mounting clamp assemblies to the rear enclosure
using the M6 x 25 screws provided, pushing the screws through
from inside the phone.
3. Tighten nuts to a torque of 4.5Nm max.
IMPORTANT: avoid the use of power tools. Spinning the nuts too
quickly can cause a rapid increase in heat which can cause the nuts
to seize as a result of galling or cold-welding.
Note: only use the outer four holes, and ensure that the screws seat
properly in the plastic bushes to avoid water ingress.
4. Ensuring that the glands are at the bottom, pass a proprietary
banding strap round each of the pole mounting clamps and the
support pole. Tighten securely.
5. Continue the installation by making the appropriate connections
(section 6) and re-fitting the face plate.
6. Re-tighten the straps firmly and trim off any excess band material.
For security the driving head of the band may also be sawn off.

VR & Help Point 11
5.3. Flush mounting
Note that it is the installer’s responsibility to prevent moisture coming
into contact with the electronics and connections on the back of the
faceplate.;
To flush-mount the telephone to a wall:
1. Prepare a recess (at least 50mm deep) in the wall according to the
dimensions shown.
2. Mark the wall with hole centres based on the dimensions shown
(155 x 326mm). If necessary offer the faceplate up to the wall to
check alignment. Do not use the telephone as a template for
drilling.
3. Drill holes in the wall at the marked positions. Select appropriate
screws, wall plugs etc., for the type of wall, bearing in mind that the
weight of the complete phone is around 1.5kg.
4. Route the cable to within the recess, and make connections to the
telephone as shown in section 6.
Secure the telephone to the wall taking care not to trap any wires. Note
that the gasket on the rear of the faceplate is intended to make a
weather seal when compressed against a smooth surface. Do not rely
on this gasket to keep water out if mounting directly to rough surfaces

12 VR & Help Point
such as brickwork – in these cases use additional sealant around the
edges to ensure a weatherproof seal.
6. Connections
6.1. Standard Connections
Connect the telephone line A and B to the main terminal block CON1 as
shown.
The centre earth terminal is intended for connection to a local earth to provide
common mode protection from lightning transients. If this terminal is not
earthed there is an increased risk that the telephone could be damaged
by line-born transients.
Note that user safety from the telephone network is provided by isolation and
does not rely on this earth connection.
Note: Conductor sizes to be 0.5mm-2.5mm
2
(flexible cable); 0.5-4.0mm
2
(solid cable) The terminal block can be disconnected from the circuit board
for easier installation
Cabling must not infringe EC Low Voltage Directive (LVD) 2006/95/EC.
6.2. Supplementary Power supply
GAI-Tronics hands-free telephones can be equipped with a supplementary
power supply, required to power the induction loop (if fitted), external relays (if
fitted) and generally to provide increased audio output level.
The standard telephone does not require this supplementary supply for
normal operation, but note that ringing on exchanges with low ring voltages
(<40Vac) may be unreliable without a supplementary supply.
A B
A B- +

VR & Help Point 13
The supplementary power input is provided on CON1A as shown and must be
an earth-free isolated supply of 12V dc (250mA min) to suit the power
requirements of the required peripherals, suitable for connection to a TNV-3
circuit.
Note: A common supply cannot be used for multiple telephones unless the
unit is equipped with an isolated power supply input. This is available as an
option if specifically ordered. Contact GAI-Tronics for details.
CAUTION: occasional problems have been observed with certain 3rd party
switched-mode power supplies. GAI-Tronics cannot accept responsibility for
the performance of any 3rd party supplied power supply. If in doubt always
use a power supply provided by GAI-Tronics.
6.3. Optional relay outputs
GAI-Tronics hands-free telephones can be equipped with external relay
outputs, controlled by the telephone software. Note – these optional
connections are only available if specifically ordered, and are not field
upgradeable. A supplementary power supply (see section 6.2) is also
required. Contact GAI-Tronics for details.
The additional outputs are provided on HD9 & HD10 as shown and are
isolated SELV outputs as defined by EN 60950-1.
To comply, the installer must ensure that any connections are within SELV limits.
Relay ratings / SELV limits: 30Vdc, 42.4V peak (resistive load)
Max switching current: 3A

6.4. Optional external inputs
GAI-Tronics hands-free telephones can be equipped with 4 external inputs,
which can be used to generate call-in events or alarm reports (using TMA).
Note – these optional connections are only available if specifically ordered
and are not field upgradeable. Contact GAI-Tronics for details.
The inputs are provided on HD4 as shown, and are also labelled on the circuit
board. Control inputs are for connection to voltage free contacts only. Internal
pull-up resistor source current = 33µA. These inputs form part of a TNV3
circuit and precautions must be taken to prevent hazardous voltages being
applied to these circuits.
NB these inputs are not isolated from the telephone network.

16 VR & Help Point
7.2. Further programming options
In addition to programming auto-dial numbers, several other features
can be programmed using a tone-phone.
7.2.1 Time-out
The call time out is factory set to 7 minutes, meaning that the phone will
drop the call and go back on hook electronically after this period even if
a call is in progress. This feature is provided to guard against the
handset being left off hook and tying up the line.
The timer can be set in increments of 10s from 60s to 9980s by entering
the code *50, followed by the required timeout divided by 10s, followed
by #.
For example to set the timer to 3 minutes enter *50 18 # (3min is 180s,
18 is 180/10).
This command must be entered between entering the PIN and closing
the phone down with *99 (ie during step 5 of the quick programming
guide above).
To disable the timer use a value of 999, ie *50 999 #.
The phone will respond to a successful command with a single tone.
7.2.2 Inserting a pause into an auto-dial number
To enter a pause (approx 1 second gap) into a dial number, use the
digits *1.
For example to program 9 <pause> 12345 into memory 1, use
*101 9 *1 12345 #
This command must be entered between entering the PIN and closing
the phone down with *99 (ie during step 5 of the quick programming
guide above)
7.2.3 Auto-answer behaviour
To set a SMART help point to automatically answer in a voice call, use
*70 0 #
To set a SMART phone to answer immediately, and only ring after auto-
answering (ie for silent monitoring), use
*70 240 #
The actual formula for rings before and after auto-answer is
*70 n #
Where n is a number between 0 and 255 calculated as follows:

VR & Help Point 17
n = 16xRa + Rb,
where Ra is the number of rings after autoanswer, and Rb is the number of rings
before autoanswer
This command must be entered between entering the PIN and closing
the phone down with *99 (ie during step 5 of the quick programming
guide above)
7.2.4 Receive level
To change the receive level, use
*72 n #
Where n is the level in dB, minimum 10, maximum 31, the factory default
setting is 26.
This command must be entered between entering the PIN and closing
the phone down with *99 (ie during step 5 of the quick programming
guide above)
CAUTION - changing this level may cause the phone to be too loud or
too quiet, and in extreme cases could affect the semi duplex operation.
To set the phone back to its factory default volume setting use
*72 26 #
7.3. TMA
GAI-Tronics TMA is a fully featured software application (Telephone
Management Application) for Windows™, offering the facilities to program,
maintain, monitor and report on all types of GAI-Tronics SMART products.

8. Cleaning
Recommended cleaning methods are outlined below:
8.1. Normal Cleaning
For normal cleaning we recommend "Virosol", manufactured by Clover
products.
Carefully follow manufacturer's instructions for storage, handling and use.
8.2. 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.
8.3. Graffiti
For graffiti, paint and ink we recommend the use of 3M GR1 graffiti stain
remover.
CAUTION: This is a very aggressive chemical. Pay close attention to the
manufacturer's recommendations for storage, handling and use.
8.4. 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
