35
is an alarm that combines into a single, compact system a powerful
alarm that detects both Carbon Monoxide (CO) and explosive
gases propane (LPG) and Methane Natural Gas).
The 35 series uses the latest microprocessor technology combined
with two electronic self-cleaning sensors that operate independently
of each other. The combined unit can detect CO and explosive
gases simultaneously.
OPERATION
When the unit is first powered up, The CO sensor requires a ten
(10) minute initial warm-up period to clean the sensor element and
achieve stabilization. The GREEN LED indicator will flash on and
off during the 10 minute warm-up period. The unit cannot go into a
CO alarm during the warm-up period. To test your unit during the
warm-up period, press the test button. See Test Procedure in this
manual. After the warm-up period, the GREEN power ON indicator
should glow continuously. If the ON indicator does not light, see the
section,
Trouble-shooting Guide,
in the user’s manual for
further information.
DO NOT attempt to fix it yourself.
Gas Alarm:
When you power the alarm, it has a warm-up period
of approximately 1 minute. This unit cannot go into a gas alarm
during the warm-up period. After 1 minute the alarm can detect
explosive gas and will energize the relay on models 35-742-R and
35-742-R-MS.
Simultaneous CO and Gas Alarms—
Because the risk of a
propane gas explosion is generally a more serious danger, your
alarm unit gives the gas alarm a higher priority during simultaneous
alarm condition.
If your unit generates alarms for both Gas and CO at the same
time, the gas LED will flash red and the beeper will sound. The CO
LED will be a solid RED until the CO is ventilated out of the RV, at
which time the LED will return to the GREEN operation/safe color.
Brownout Protection—
The unit can tolerate short power
interruptions and brownouts where the circuit voltage drops as low
as 1 VDC. If the brownout lasts too long, the unit will reset and
operate as described above.
LOW POWER OPERATION
This alarm will operate normally down to 7 VDC. Do not operate
this alarm below 7VDC.
