Important Notes On Commissioning - Telecom Behnke 10 series Kurzanleitung

I M P O R T A N T N O T E S O N C O M M I S S I O N I N G
Thank you very much for buying a quality product from the
Behnke company. Your hands-free telephone has special
features, which you should take into account when
installing and configuring the unit:
(A) The hands-free telephone can be used on an
analogue PBX extension or on an analogue direct
exchange line.
(B) The hands-free telephone can be used without any
additional power supply.
(C) The hands-free telephone works in full-duplex
mode (and can be switched to semi-duplex and
simplex).
Observing the following 9 notes, you will achieve the
greatest possible operating safety and speech quality with
your Behnke hand-free telephone.
1 . M O U N T I N G C O N D I T I O N S
• The optimum mounting height is when, during opera-
tion of the unit, there is a horizontal distance of 30–50
cm between the user and the loudspeaker and micro-
phone.
• Always choose the greatest possible distance between
microphone and loudspeaker. Thus you will obtain the
highest possible intelligibility in full-duplex mode. (See
also Behnke volume classes in the product catalogue.)
• In the case of rear-mounting modules (i.e. modules
mounted behind an existing front wall or, for instance, a
car operating panel), make sure that there are large
enough sound inlet holes in front of the microphone
and sound outlet holes in front of the loudspeaker (at
least 50% of the loudspeaker membrane surface for
sound exit and 50% of the sound inlet of the micro-
phone casing).
• To ensure best sound quality, always mount rear-mount-
ing modules flush (without a distance) behind their
front wall. The supplied gasket must be mounted
between front wall and module.
2 . O U T D O O R M O U N T I N G
• Only use Series 10 hands-free telephones in moisture-
protected situations.
• Hands-free telephones must be protected from direct
rain exposure.
• When Series 20 hands-free telephones are used at
weather sides, they should be equipped with a rain
guard in the case of flush mounting or with a surface-
mounted casing in the case of surface mounting.
• In the case of flush mounting, always seal the upper
edge of the telephones well to protect them from rain-
water (especially when the wall is not level, using e.g.
silicone), but at the lower edge leave a space in the cen-
tre unsealed to allow the water to run out.

Take care to ensure correct seat when mounting the sup-
plied gaskets. In the case of Series 10 telephones this is
important for good sound quality and moisture protection
of the unit. In the case of Series 20 telephones this is
important for moisture protection. The gasket must be
seated snugly on the frame of the flush- or surface-mount-
ed casing.

• For basic electronics packages 20-0005, 20-0006 and
20-0018: 25 m max.

20-0022 and 20-0028: 25 m max.
• The loudspeaker and microphone each require the same
distance as the buttons.
5 . C A B L I N G
• Use Behnke patch cables or shielded cables such as IY-
ST-Y or AY-ST-Y for mounting. Connect the cable shield
to the –12-V terminal of the special-purpose hands-free
telephone or lift emergency telephone (not to earth!).
• Extension of buttons with unshielded cables may result
in malfunctions of the basic electronics package.
6 . O R I G I N A L B E H N K E P A R T S
Only use original Behnke parts as accessories or spare
parts – this also applies to plug-in power supplies! Only
this will ensure a trouble-free operation.
7 . C O N F I G U R A T I O N
The hands-free telephones may be configured locally on
the basic electronics package, remotely by telephone
(DTMF) or through a Behnke control station.
Alle hands-free telephones come with a factory standard
configuration.
