The LPBD521 module is used to drive the FireRay
2000 beam detector units directly from the
MINERVA loop. A single LPBD521 can be used to
power the analyser unit, the beam receiver unit
and the transmitter unit. Alternatively, two
separate LPBD521's can be used with one to
power the analyser unit and receiver units and the
second to drive the transmitter separately, either
from the same loop or a different loop. Up to 12
LPBD521's can be used per loop.
The module is addressable and will therefore take
one address on the loop.

LPBD521 - Loop Powered Beam Detector Module
The LD40 linear heat detection system is used to
monitor fire (or overheat) conditions in confined
or polluted areas or where there are adverse or
unusually variable environmental conditions. The
sensor cable is unaffected by dust, moisture or
vibration and requires little maintenance.
Features
• Easy and cost effective installation
• Good sensitivity with adjustable alarm
threshold
• Open and short circuit monitoring
• Suited for outdoor and indoor applications
• Can be used in hazardous areas
• Mechanical protection is provided for cables in
areas where damage may occur
• Chemical resistance sheathing is available for
areas where petro-chemical corrosion may
occur.
