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 light does not light, see the
section,
Trouble-Shooting Guide
, in this 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 70-742-R and 70-742-R-
MS.
Simultaneous CO and Gas Alarms–
Because the risk of a propane
gas explosion is generally a more serious danger, you 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 operational/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 7 vDC.
VISUAL AND AUDIBLE ALARM SIGNALS
This SAFE-T-ALERT™ CO/Propane Gas Alarm is designed to be
easy-to-operate. The alarm has two indicator lights that display a
specific color for each monitored condition. There also is a matching
sound pattern for alarm conditions.
