IN CASE OF FIRE

CHECKFIRE MP-N Electric
Detection and Actuation System Manual
Read these precautions carefully until they are clearly understood.
All equipment operators or anyone who has any responsibility for
the equipment should fully understand how the CHECKFIRE
MP-N Detection and Actuation System operates. Every operator
should be fully trained in these procedures.
1. When the system alarm sounds, bring the equipment to a safe
controlled stop, shut off the engine, and exit. (Equipment left
running may add fuel to the fire or reignite the fire with heat or
sparks.)
Automatic Equipment Shutdown – The CHECKFIRE MP-N
system is equipped with a shutdown relay and time delay. If a
shutdown device is connected to the system, all responsible
personnel should understand shutdown device operation and
the length of the time delay (in seconds). If the DELAY button
(on the control module cover) is pushed and released before
the end of the shutdown time delay period, the time delay will
automatically repeat itself. This delay can be repeated (using
the DELAY button) as many times as is necessary to stop the
vehicle safely before it shuts down. (The DELAY button can
also be held in indefinitely to delay shutdown – the shutdown
delay will then restart after the button is released.)
The CHECKFIRE MP-N system can utilize an explosion-proof
pressure switch for shutdown. If the pressure switch is
connected to the system, all responsible personnel should
understand shutdown device operation and the length of the
time delay (in seconds). If the delay/reset button (on the
control module cover) is pushed and released before the end
of the pre-alarm time delay period, the time delay will auto-
matically repeat itself. This delay can be repeated (using the
delay/reset button) as many times as is necessary to stop the
vehicle safely before it shuts down. (The delay/reset button
can also be held in indefinitely to delay shutdown – the pre-
alarm delay will then restart after the button is released.)
2. Move away from the equipment taking a hand portable extin-
guisher along if possible.
3.
In case of fire, evacuate area to lessen risk of injury from
flames, heat, hazardous vapors, explosions, or other
hazards that may be created.
Stand by with a hand portable extinguisher to guard against
any fire that may reignite after the fire suppression system has
been discharged. Remain alert until the equipment cools and
the possibility of reignition is no longer a threat.
Manual System Actuation
The system can be actuated manually by pulling the ring pin and
striking the red button on the manual/automatic actuator as shown
in Figure 41. Again, bring the equipment to a safe stop, shut off the
engine, manually actuate the system, move a safe distance from
the vehicle, and stand by with a hand portable extinguisher.
