M8A1 Chemical Alarm . . .
Because the M43A1 has a radioac-
tive source, put on the air outlet filter
to trap radioactive particles before you
turn it on indoors. Be careful putting
on the filter. If you force it on, it breaks
the outlet port. That’s a depot-level fix.
If the filter doesn’t turn clockwise eas-
ily, you’ve put it on wrong. Take it off
and try again.
Because of its radiation source, the
M43A1 detector must be wipe tested
yearly for leaks. So check the label on
the detector cell for the next due date.
If the test is past due, the M43A1 is
NMC.
Feel the M42A1 remote alarm’s horn
knob for looseness before you go to
the field. The knob often works loose
and disappears. Your commo people
Better yet, order a snap-on adapter,
NSN 4730-01-350-1584, that makes it
easier to put on the filter.
Remember, to purge the M43A1 the
toggle switch must be pointing in.
Otherwise, the detector will shut down
before it’s through purging. Flip the
switch back out when you’re finished.
Once you’ve purged the M43A1, you
can’t pitch the outlet filter because it
now contains radioactive particles.
Don’t touch it with your bare hand,
either. Put its plastic shipping bag over
it to unscrew it and then seal the filter

The best thing you can do for your
alarm’s M43A1 detector is simply to
run it. If it sits for weeks, it could take
hours to purge the detector cell when
you’re ready to detect. So, run it at
least 1 hour every month.
