Apollo 3300 IB 1978 - Page 20

Each remote
detector
has
an LED
that
monitors
the
gas
sensor
ele-
ment’s
heater
current.
This
LED
should
be
ON when
the
POWER
switch on
the Monitor
Panel
is ON.
Ifthe
LED
is not
ON, the
remote
detector
is inoperative
and
must
be serviced
or replaced.
3. Nuisance
alarms can
be caused
by small amounts
of alcohol
vapor (less
than 2%
of the L.E.L.).
Nuisance
alarms may
be silenced
for 10
min-
utes by pressing
the MUTE
pushbutton.
A NUISAN
CEalarm must
be
treated
as a REAL alarm
until the
source has been
clearly identified.
Common
sources for alcohol
vapors
include: aftershave
lotion, co-
logne, stick
deodorant
and heated alcoholic
beverages.
Small amounts
of certain
other vapors
will also sound
the alarm. Included
are: methyl
alcohol, isopropyl
alcohol, acetone,
M.E.K.
and benzene. These
sub-
stances
are toxic to humans
and should
not be used without
adequate
ventilation.
Hairspray and
other aerosols
will sound the alarm;
however,
these
vapors
are highly volatile and
must be treated
as potentially explosive
gases, especially
in confined spaces.
4. During
periods of vehicle
storage the
Gas Monitor should
be switched
OFF to avoid
discharging the
vehicle’s storage
batteries. When
the Gas
Monitor
is switched
OFF the
vehicle’s
L.P.G. tanks should
be shut off
as a safety measure.
The Gas Monitor
should
not be left on
for more
than
48 hours (4
detector system)
without recharing
the vehicle’s
stor-
age batteries.
If a battery
charger is connected,
the system
may be
left
ON continuously.
5. Low
battery voltage
(5 to 6 volts)
will cause the
alarm to sound,
but
none
of the
DETECTOR
LED’s on the Monitor
Panel
will be
ON. The
battery should
be recharged
when this
occurs.
If The
Alarm
Sounds:
1.
DO NOT
switch on lights or
strike a match.
2. Evaluate
the vehicle.
3. Leave door
and windows
open.
4.
Shut
off
LP Gas at the tanks.
5. Alarm automatically
resets
when
gas is at
a safe level.
