It is most important that any accessory designed for use with Sepura mobile
terminals does not affect any of the current approvals
DECLARATION OF CONFORMITY
Sepura mobile terminals and approved accessories are compliant with the essential
requirements of the 1999/05/EC Radio and Telecommunications Terminal Equipment
(R&TTE) Directive. The mobile variants and accessories are specified in the Declaration of
Conformity number DC/C 02001-3.
A copy of the declaration is available from Sepura on request.
As such, Sepura mobile terminals are compliant with the following mandatory specifications:
Safety to relevant parts of EN 60950 (Safety of Information Technology Equipment). This
includes the Low Voltage Directive (LVD);
Electromagnetic Compatibility (EMC) to relevant parts of EN 301 489 (Electromagnetic
Compatibility & Radio Spectrum Matters);
TETRA air interface to EN 303 035 (Terrestrial Trunked Radio (TETRA); Harmonized EN for
TETRA equipment covering essential requirements under article 3.2 of the R&TTE Directive);
In addition, Sepura mobile terminals and Third Party Accessory must also maintain
conformance in the following areas:
Dust & moisture protection to IP54 or greater to meet the needs of the user environment and
the relevant parts of ETS 300-019; CEN1789:2000
Protection against Acoustic Shock to relevant parts of ITU P.360. Sepura mobile terminals
comply with the maximum audio levels specified for Longer Duration disturbances.
The performance of the mobile must not be compromised by the r.f. field generated by the
mobile interfering with the accessory (different versions of Sepura mobile terminals operate
over frequencies within the range 350 MHz to 900 MHz and generate signals complying with
TETRA standards).
For example no audio interference should occur when a TETRA portable transmitting at 1 W
r.f. power, at frequencies between 300 MHz and 900 MHz, is held within 1cm of the
accessory.
The product shall not degrade the performance of a SRM/G 3500/3900 installation when
tested to TETRA EMC spec. EN 301489-1&18 V1.6.1 (2005-09) Including Annex B.
The combination of the accessory and the mobile must be ―fit for purpose‖. The use of an
accessory must not make the mobile difficult or awkward to use, or in any way degrade its
performance.

The “technical file” must be approved by Sepura prior to the Third Party supplying
the Accessory to customers.
Sepura requires the designer/manufacturer to:
Allow Sepura to review, and comment on, the ―Test Plan‖ — this document will
describe the tests to be performed by, or on behalf of, the Third Party accessory
designer/manufacturer to confirm continued compliance with the above specifications,
Provide Sepura with a ―technical file”, which shall contain design details and results of
tests undertaken and the appropriate Declaration of Conformity. The information must
be approved by Sepura prior to the Third Party supplying the Accessory to
customers.
Sepura must be notified of any amendment to the approved Accessory which could
affect the continued conformance. In the event that there is a problem, perceived or
real, with the interaction of Sepura mobile terminals and the supplied Third Party
Accessory, the Third Party must make available to Sepura documentary evidence of
relevant test results.

For details of the SCC accessories interface, see document MOD-10-1253 for further
information
INTERFACE OVERVIEW
The Mobile and Gateway products are available as a one, two or three unit solution
supporting a mix of up to two Consoles or Application Interface Units (AIU) plus the
transceiver, allowing the radios to be used in many different applications and support up to 4
audio accessories such as handsets, fist microphones and headsets.
TRANSCEIVER
The SRM and SRG series of transceivers support:
2 off Console Interfaces - each can support a Console, an AIU, or an external data
application connected via a Sepura data lead. Any combinations of units on the two
Console Interfaces are possible. The Console interface is also used to customise and
program the unit via Radio Manager.
1 off Power interface providing connection for the battery, ignition sense line and also
the transceivers speaker.
3 digital inputs and 1 digital output on the power interface connector
1 off RF connector for the Tetra antenna.
GPS connector (optional).
CONSOLE
Each Console provides:
2 off AAI ports allowing connection of two audio accessories. Each AAI supports
optional hook signalling, PTT input and up to 6 accessory keys.
1 off data interface with RS232 PEI port allows connection to an external data
application via a Sepura Data Lead. The interface is also used to customise and
program the unit via Radio Manager.
The extra 3 digital inputs and 1 digital output available on the transceiver power
interface connector are not available from the console.
