General Information
The
BM350
gas monitor offers a robust, easy to use, cost effective approach to providing a gas
monitoring system where safety matters.
The
monitor’s
fibreglass
housing is weather and corrosion resistant. It is suitable for installation
where general equipment is in use. The housing door is hinged on the left side and is secured
on the right with one latch. The display screen and status lights are visible through the
transparent hinged cover. Optional mounting feet can be fixed to the back panel for vertical
mounting.
The alarm buzzer is located at the bottom of the unit and is on the left side of the power input.
The gas sensor element is located on the bottom of the unit on the far left hand side. (or on a
3M or 5M trailing cable)
A large LCD display indicates vapour level.
The concentration of Vapour
is displayed in either parts per million (ppm) or milligram’s per
cubic meter (mg/m
3
) depending on your specific requirements.
The unit has an alarm, both audible and visual, and when a predetermined level of s is reached
the alarm is activated, this alarm level is set at manufacture to customers requirements
The monitor incorporates three fuses one domestic 3 amp plug head fuse, and one internal
circuit board mounted 1A time delay fuse, and one 2A fuse to protect the alarm relay.
If required an external alarm or device can be connected to the unit to provide other warnings of
alarm level see installation instructions for more detail.
The monitor is very easy to operate and requires no specialist knowledge or training.
Automatic self-test
The monitor incorporates a self testing feature, to quickly inform the user that monitoring is
compromised, all foreseeable modes of failure have been taken in to account, in the unlikely
event of a system failure the user will be alerted by the sensor malfunction light.
Operating requirements
The unit requires connection to a permanent electrical supply, see specification for your model
on page.
Consideration should be given to the power connection, if possible try not to use switched
sockets or extension leads as these can easily be turned off leaving the monitor without power.
The monitor is designed for
indoor use only
and should not be exposed to very high levels of
condensing moisture.
Technology
The monitor uses the latest printed circuit technology, component parts have been
selected to
provide a high level of reliability combined with low drift over time.
