Induction Loop Amplier Module for barrier-free communication
Commend – Communication and security for everyone
Induction loop amplier modules for sound transmission to hearing aids are
an essential part of Commend’s product portfolio. Upgrading WS stations to
barrier-freeness has never been easier. As an add-in circuit board with on-board
induction loop, the module may be small in size but is a huge advantage for us-
ers of hearing aids. Designed specically for public locations such as building
reception areas or on-street help points, the modules deliver Intercom audio in
high Commend quality directly to hearing aids. Being hard of hearing doesn’t
have to be a barrier – especially with Commend induction loop modules. Take
the opportunity to upgrade your system to barrier-freeness and provide opti-
mum conditions for all Intercom users with the benets of the world’s leading
Intercom technology.
Features and Highlights
– A fully integrated, IEC 60118-4 compliant induction loop system enables
wearers of hearing aids to receive Intercom audio signals in clear, uninter-
rupted quality.
– Flexible integration into vandal resistant or polycarbonate WS stations
without camera or TFT-display
– Energy-efcient and power-saving technology with low heat generation.
– Functions as MLC (Metal Loss Correction) and AGC (Automatic Gain
Control) for easy startup and faultless operation.

- JST plug (type: PAP-02v-s)
Power supply: external supply 15 – 26 VDC
(max. power consumption 8 W)
Extent of supply
– Induction Loop Amplier Module
– Induction Loop and mounting kit
– Sticker with hearloop symbol
– Line-In connection cable
Requirements
– Power supply: 15 VDC - 26 VDC
– WS station without camera or TFT-display
– Flush Mount Kit (WSFB 50x) or Surface Mount Kit (WSSH 50x)
Mounting instructions / Restrictions
– Do not expose the station to extreme temperature.
– Observe the country specic standards for installation, mounting and
conguration.
– When opening the stations ESD precautions must be observed.
– The housing may only be opened by authorised service engineers.
– Induction Loop Performance compliant with IEC 60118-4 (when correctly
installed)
– Metal Structures signicantly affects performance of the induction loop
system. The magnetic eld generated by an induction loop system,
induces a current in any closed path of a metal structure placed in the
vicinity of the induction loop. These induced currents tend to weaken the
magnetic eld and cause loss.
Examples of metal structures:
– Lightweight oor construction with a (usually proled) metal sheet
under a thin reinforced concrete slab.
– Girders, beams, constructional metal work
– Metal cladding and walls
– Metal box construction (elevators, lifts)

Please follow the following instruction for the installation of the Induction Loop Amplier module:
– Open the WS station - instruction see respective short reference
– Disconnect the station from the Intercom network and if used, from the external power supply.
– Mount the Induction Loop on the surface or ush mount box as shown in the following picture
– Snap the Induction Loop Amplier module in the slot of the WS station:
– It is only possible to snap the module in the middle slot of the WS station!
– If in the middle slot a Camera module or a TFT-Display module is used, it is not possible to mount the induction loop amplier module.
Quick Start
Note:
It is mandatory to install the induction loop on the right side of
the housing, as shown in the connection diagram. Otherwise
disturbing hum may occur. For the installation use the attached
mounting clips and screws (in extent of supply).

– Carry out the connection of the induction loop, signal input and power supply
– Connect the loop cable (polarity does not matter) via the screw terminals as shown in the following picture.
– Connect Line-In with the connection cable (in the extent of supply) - as shown in the following picture.
– Connect power supply (15 VDC - 26 VDC) as shown in the following picture.
Note: If an external power supply is used for the terminal, it is possible to use this power supply also for the Induction Loop Amplier Module.
– Switch on the external power supply and check if the green “Power” LED illuminates!
– The potentiometers “Level-Input”, “MLC” and “Loop Current” are preset at factory delivery.
– Test the performance of the system using a loop receiver or eld strength meter and adjust ‘MLC’ & ‘LOOP CURRENT’ to achieve acceptable performance -
please consider the respective norm!
– Mount the Intercom Station - see short reference Surface / Flush Mount Kit.
– Place the sticker with the hearloop symbol onto the frontplate of the Intercom Station.
