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)
• Call status LED
• Auto-dial numbers are remotely programmable
• Line powered operation (optional supplementary power supply available)
• Optional cast aluminium rear enclosure
• Optional induction loop for the hearing impaired.
• Optional isolated input for power supply
• Optional relay outputs (2)
• Optional logic inputs (4)
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.

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 telephones1

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
