Use of the ‘M-Fire Unit’
Connection and preparing for use
[The information below applies only to a set-up with a separate operation console]
Connect the gas hose and the cable from the operation console to the burner unit.
Next, turn on the gas valve and check that there are no leaks.
If there is a mains power supply available, you can connect the operation console to this. If there is no
mains power supply, the M-Fire console will operate on the built-in battery. This must of course be
charged.
Pull out the emergency stop switch
and switch on the “power” switch.
The system is now ready for use.
When using the M-Fire Unit within a confined space, the following requirements must be met:
•
The distance between the unit, the walls and the ceiling must be
3 metres or more
. The walls and
ceiling must be made of non-inflammable material and must be able to withstand high
temperatures. The volume of the confined space must be
at least 150 m
3
.
•
Sufficient ventilation
must be provided to a) ensure oxygen supply for combustion, and, b)
prevent the formation of inflammable and explosive mix by residual gases. Since propane gas is
heavier than air, any residual gas will sink to floor level. Therefore,
there must be ventilation
along the floor surface!
•
Alternatively:
The area should be especially designed for fire simulations.
Operation
The operation of M-Fire Unit can be carried out in 2 different ways. By means of the selector switch,
“hand” or “auto” can be chosen.
“Hand” (manual)
The instructor determines the operation by holding down the start button.
The “M-Fire Unit” will ignite automatically by means of an electrical ignition.
Acoustic signal prior to the start: 4 beeps of approx. 0.3 seconds with the same length of time in between.
Next, the fire will ignite as determined by the selector switch:
A: Burner 1
B: Burner 1 + 2
C: Burner 2
Ignition starts simultaneously with the gas supply.
Once the fire has been put out (detected by the sensors, or, by releasing the
Once the fire has been extinguished (detected by sensors or by releasing start button), the gas supply shuts
off and an acoustic sound will be produced (a long beep of approx. 1.5 seconds). After a waiting time of
approx. 5 seconds, the unit will be ready for use.
The gas supply will be shut off and the Fail LED will flash if the unit has not ignited after 10 seconds.
After a waiting time of approx. 5 seconds, the unit will be ready for use.
“Auto” (automatic)
The operation will be started by the instructor by pressing the start button. An acoustic sound signal will
be produced while the start button is being pressed: 4 beeps of approx. 0.3 seconds with approx. 0.3
seconds gap in between.
After this sound signal, the start button should be released
, whereupon
the M-Fire Unit will ignite automatically and will run the chosen programme cycle (A-B-C on the selector
switch). The gas supply will be shut off and the Fail LED will flash if the unit has not ignited after 10
seconds.
