1. Safety and Care Information
▲
THIS TELEPHONE IS FOR
THE KETS (Kestrel Emergency Telephone
System) ONLY. DO NOT ATTEMPT TO CONNECT THIS TELEPHONE TO
A PABX or PSTN LINE OR TO PETS.
▲
The safety of the user/installer relies on the isolation of the telephone
network and not on the earthing of the case
▲
Pleas
e read these instructions 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 7)
2. Product Description
This manual describes the KETS 1141 model Titan telephone, designed for
use on KETS (Kestrel Emergency Telephone System) at automatic half
barrier (AHB) level crossings in the UK. The product was introduced as an
alternative to PETS, and delivers the functionality of PETS, but is not
electrically compatible with any PETS interface. It can only be connected to a
dedicated KETS interface.
The product identity label is BROWN (as opposed to the blue label visible on
PETS units)
For the full list of product features, please see the specifications in section 11.

3. KETS System Summary
KETS is an "omnibus" system, meaning that all the telephones are connected
in parallel on a single cable pair from the crossing to the concentrator.
In practice all the phones at a crossing are connected into a Line Termination
Unit (LTU), but this is a passive device containing only line conditioning
components, terminals to connect up to 4 devices to a common pair and an
ON OFF switch to isolate all crossing phones from the line. The ability for 4
telephones to work independently on a single pair with detailed fault
monitoring and without interfering with each other relies on each telephone
being an intelligent device with its own unique address on the system.
4. Addressing Procedure
To make sure that a KETS phone automatically acquires the correct address
the rules are simple:
1. Only apply power to a phone when the handset is OFF HOOK.
2. Always test ALL phones at a crossing before leaving site, even
if only a single unit has been changed.
These rules apply equally to a complete new crossing installation or
replacement of a unit or units on an existing installed crossing.
If a KETS phone powers up with the handset on hook, it will retain its previous
address. So, in the event of temporary disconnection or power interruption, all
phones will retain their original addresses and function normally.
When installing or replacing a phone, it is essential that it does not retain any
previously set address, for example from another crossing, which may cause
a conflict. Powering up with the handset off hook will force it to acquire a new,
unique address.

KETS 1141 Titan Illuminated Crossing Telephone 7
Always check the function of all KETS phones after any replacement has
been made. If any individual phone does not perform as expected, it is usually
because the above procedure has not been followed. In this case follow
these steps to recover:
•disconnect power from all the phones (using the LTU switch),
•take all the handsets off hook,
•turn the LTU switch back on
•Replace all the handsets one by one
This will ensure that every phone acquires a unique address.
Note this situation can only occur as a result of maintenance activity, not
during normal operation or as a result of power or line interruption.
5. Operation / Testing
Normal operation of the phone is as follows:
Open the door - the illumination panel will come on
Lift handset - dial tone is heard but the call does not start.
Press button - ring tone is heard until the call is answered.
The call is cleared when the signaller hangs up, regardless of whether the
user hangs up.
When a call is made from the signal box back to the crossing, all KETS
phones on the line pair will ring.
When a handset is lifted the call is connected to that phone, and all the other
phones will stop ringing.

6. Installation
6.1. 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: installation must be carried out by
trained personnel. Contact GAI-Tronics if installation service is required.
1. To prepare for installation, open the door, then undo the four retaining
screws to remove the faceplate from the rear enclosure. A 3mm Allen
key is required.
2. Line connections are on the reverse of the faceplate, on the lower edge
of the PCB as it protrudes from the back box.
3. The Titan telephone is intended for vertical installation to a wall or pole.
Select the required mounting method (section 6) and mount the rear
enclosure first where applicable.
4. Route the required cable through a gland as appropriate.
5. Make sure the handset is off the cradle before connecting the
telephone to the line
6. Make connections following section 7.
Ensure that both cable entries are sealed with either a gland or a black
blanking plug as described.
7. Replace the handset on its cradle.
8. Re-fit the faceplate ensuring a weatherproof seal is maintained.
9. Test the operation of the telephone (sections 4 & 5) noting that all KETS
phones at the crossing must be tested before leaving site. Installation is
now complete.
6.2. If glands are required
Before mounting the telephone, check the cable routing and requirements. If
glands are required, fit them to the case as follows:

KETS 1141 Titan Illuminated Crossing Telephone 9
1. Remove the RED blanking plug leaving the other (usually BLACK) in
place.
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. Proceed with chosen mounting method
below
As standard, the telephone is supplied with a pole mounting kit, part number
100-02-0208-001.
6.3. 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: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 7) and re-fitting the face plate.
