HSL offer a
comprehensive spares and repair
service for all types of headset,
helmet and handset. We are
ISO9001:2000 and EASA Part145
approved workshop where repairs,

Headset Services
Limited is the UK and Europe
distributor for the Polycon
waterproof radio intercom
system from Aksnes
in Norway. The Polycon Radio
system in the aircraft interfaces
straight into the aircraft's
intercom. The winchman can
talk on the intercom via
his Polycon radio as if he
is in the aircraft, completely
hands free giving him more
mobility and improving safety.
Headset Services Limited
also provide a range of headsets
and helmet upgrades to interface
with the Polycon system.
We make a waterproof helmet
loom upgrade for most helmets
that provides a complete
and reliable communication
system.
Radio
Transceiver
The
Polycon Transceiver
is constructed
to meet the stringent
quality requirements
for equipment used
under demanding
conditions typically
for helicopter
search and rescue
operations, and
other outdoor activities
which often take
place under extreme
operational and
environmental conditions.
The Transceiver
is designed for
ease of operation
without compromising
the integrity of
the unit and safeguarding
against interruptions
caused by unintentional
operation. The
whole unit is constructed
as a multifunction ‘ PTT’ key,
with additional
standard radio
functions.
The
unit can be used
as a dedicated
waterproof intercom
for SAR (Search
And Rescue) operations
as well as a standard ‘walkietalkie’ radio.
The radio incorporates
the PTT switch/security.

Processing
Unit
The
Polycon Base
Station 004RLI
together with
one or more crewmember’s
transceivers
form a wireless
extension of
the aircraft’s
ICS. The unit
operates as a
base station
with interface
to the ICS, and
as a repeater
station for communication
between ground
crew.
The Base Station
contains an advanced
internal radio
and processing
package, which
in addition to
high system integration
tolerance offers
duplex communication
facilities. Normally
the Base Station
will be permanently
installed in
the aircraft,
and connected
to dedicated
intercom and
DC power outlets.
The communication
range of the
radio system
is dependent
of output power,
antenna location,
antenna gain
and altitude.
The 50O BNC antenna
socket can either
be connected
to a ‘unit
mounted’ antenna,
or to an external
mounted antenna
via coaxial cable.

Repair
Services
Due
to the harsh and
extreme environment
that this equipment
is designed to be
used in, the manufacturer
(Axnes Aviation
AS Norway) recommend
that the Polycon
system is periodically
inspected and overhauled
to ensure continued
serviceability and
to prevent expensive
failures due to salt
corrosion, seal degradation
and water ingress.
Polycon
System overhaul every
2 years from
date of purchase.
Polycon System mandatory
Battery replacement
every 4 years from
date of purchase

scheme which covers
periodic maintenance
and any incidental
failure in use. Call
