INSTALLATION INSTRUCTIONS
Follow these instructions carefully. Failure to follow these instructions can
damage the unit and void the warranty.
Important: The 70 Series case requires 1 1/2” (38mm) clearance.
MODEL 70-742
1.
Basic Model 70-742
- Select a wall location between 4” and 20” off the
floor. Cut a 5 5/8” (143mm) W x 3 1/8” (79mm) H hole.
2.
Connect Supply (+) to the Red wire lead. Install a 1 amp fuse in the
positive (+) circuit. Connect the Black wire to the 12 volt Ground (-).
3.
Reconnect the power supply. Warm up 10 minutes then test the alarm.
MODEL 70-742-R KIT
1.
Model 70-742-R Kit - With Normally Closed relay.
This unit supplies
a relay with contacts rated 12 VDC, 3 amp (max). The relay is energized
whenever the alarm is operational. It may be used to shut down a
generator or to open an (optional) gas solenoid valve. The relay may also
be used to interface to alarm systems, using either the normally closed or
normally open contact, depending on the requirements of the alarm
system. In the event of an alarm the relay will shut off. It will
automatically energize after the unsafe levels of CO or explosive gas
clears.
Select a wall location between 4” and 20” off the floor. Cut a 5 5/8”
(143mm) W x 3 1/8” (79mm) H hole.
2.
Mount the solenoid according to its separate instructions. You must
install the solenoid included with the 70-742-R-Kit
. Do not connect
to an existing installed solenoid.
SEE: SPECIAL WIRING
NOTICE.
Connect the Red wire and either White wire from the alarm to
the 12 volt supply (+). Install a 5 amp fuse in the positive (+) circuit
between this connection and the battery.
Connect the Black wire to the 12 volt Ground (-).
3.
Relay Output – Connect the remaining White wire from the alarm to
either black wire from the solenoid.
Ground the remaining Black wire from the solenoid to the negative side
(-) of the 12 volt battery OR ground it to the RV Chassis.
Note: Some devices do not require correct polarity and can be connected
to either terminal or wire.
4.
Reconnect the power supply. Warm up 10 minutes then test the alarm.
SPECIAL WIRING NOTICE:
When replacing CCI Controls LP Gas
Leak Detectors they may have two power leads. Safe-T-Alert units only
have one power lead. Simply connect the Safe-T-Alert power lead (Red) to
the coach/house power supply and cap or remove the other power lead.
DO
NOT CONNECT BOTH POWER LEADS TO THE Safe-T-Alert
ALARM – this will result in a dead chassis battery.
Only use UL or recognized permanent wire connectors to
replace any unit installed with spade connectors or wire nuts.
TEST PROCEDURE
!
WARNING
TO REDUCE THE RISK OF CARBON MONOXIDE POISONING
OR PROPANE GAS EXPLOSION, TEST THIS ALARM’S
OPERATION AFTER THE RV HAS BEEN IN STORAGE, BEFORE
EACH TRIP AND AT LEAST ONCE PER WEEK DURING USE BY
PRESSING THE TEST/RESET BUTTON
.
!
WARNING
WARNING: THE TEST BUTTON ONLY TESTS THE
ALARM CIRCUIT NOT THE SENSORS. YOU MAY USE
PROPANE OR BUTANE GAS TO TEST THE GAS SENSOR.
Note it may take up to 10 seconds for the alarm to sound.
TO TEST THE CO SENSOR USE A CAN OF SAFE-T-ALERT
CO TEST GAS TO TEST THE 400 PPM CALABRATION
POINT. DO NOT TRY TO GENERATE CO TO TEST THE
ALARM.
The TEST/RESET button tests all ELECTRICAL functions of
the alarm. It does not check the sensor operation.
The alarm may be tested at any time. The TEST/Mute switch is located on
the front of the alarm. Press and hold the test button for 1 second
IMPORTANT
-
If this alarm does not test properly return it immediately
for repair or replacement. If the alarm is over five years old replace it.
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. This unit cannot go into a alarm during the warm-up
period. 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 model 70-742-R-Kit.
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 operational/safe color.

DANAGER - FIRE RISK - CCI CONTROLS GAS
LEAK DETECTOR REPLACEMENT
- DO NOT CONNECT A SAFE-T-ALERT alarm to non
Safe-T-Alert supplied solenoid. You must use the new
solenoid included in your Kit. DO NOT CONNECT TO
A CCI SOLENOID.
