The Beambar 4 is a multiple
infrared Beam device for short range internal use. Four time multiplexed
beams are arranged with a separation of 75mm, an alarm being generated
if two adjacent beams are broken. Its unique expansion capability allows
a complete barrier of almost limitless height to be formed by stacking
units together. Such a barrier provides a tightly controlled detection
area with a very high probability of detection. The Beambar 4 is housed
in a white ABS box 300mm long x 44mm wide x 254mm deep, allowing a very
compact and attractive installation. Additional fixings are provided
which permit a wide range of installation options. Installation is
facilitated by the provision of several features such as test LEDs for
each beam, automatic gain reduction during installation, and
environmental outputs are provided which will warn of impending
problems.

installation
- as a replacement for
conventional wire in tube installations.
- protection of perimeter
windows, skylights, doors and walls.
- can be
used in securing of ventilation ducts.
- protection of paintings
and valuable articles).

-
INTERCONNECTIONS
- Master to
slave: 6 core
- Tx to Rx: 7
core plus one for each slave
- Severance of cables
between Tx and Rx or between master and slave will lead to an alarm
being generated.
Installation
The transmitter and receiver may be mounted either directly on to
the wall (with the beams parallel to the wall) or at 90 degrees
using the supplied bracket. Alternatively, the bracket may be used
to mount either unit continuously through 180 degrees.
Clean relay contacts are provided for the alarm (two adjacent beams
broken) and environmental (any single beam broken) outputs. Cabling
for a single unit consists of a seven core cable between the
transmitter and receiver plus cables to the control equipment as
normal.
For multiple unit operation a six core connection is required
between master and slave units plus one additional wire between
transmitters and receivers.
In a multiple unit installation all units self test on power-up to
determine if they are master or slave. Afterwards all
interconnection cables are monitored for correct operation and the
severance of any cable will lead to an alarm condition.
