Mounting guidelines
Mount the DGS on a flat surface, near the roof or the floor, and where gas leakage is more probable. Make sure to choose a location
that is not too near gas appliances, but yet not too far from such appliances.
Natural gas is lighter than air; therefore, mount the gas detector approximately 30cm below the ceiling, if the detector will be used
for the purpose of detecting this gas.
Butane and Propane are heavier than air; therefore, mount the gas detector approximately 30cm above the floor, if the detector will
be used for the purpose of detecting one of these gases.
Leave proper space between the detector and the wall/ceiling, for the ventilation slots (no. 6 in the figure above) not be blocked.
Mount the detector near a standard 220V outlet.
Do not mount the detector directly above cooking appliances, or near fans.
How to replace the battery
The battery compartment is located at the back of the DGS. To replace the battery, follow the next steps.
1.
Remove the detector from the bracket by pressing the projecting part on the bottom, and pulling it upwards.
2.
Open the battery compartment (no. 8 in the figure above); use a slotted screwdriver if required.
3.
Remove the battery and insert a new one; observe polarity! The buzzer will sound a long beep and the green LED will start flashing.
4.
Place the detector on the bracket and push it downwards until clicked into place.
5.
Test the detector - see how below.
How to install the DGS
Mount the detector on a flat surface. Follow the next steps.
1.
Remove the detector from the mounting bracket (no. 7 in the figure above): press the projecting part on the bottom and pull the
bracket downwards.
2.
Use the supplied screws and mount the bracket vertically on the designated surface.
Caution: The detector MUST be mounted in vertical position, or its sensitivity and performance
will be affected.
3.
Open the battery compartment (no. 8 in the figure above. Use a slotted screwdriver if required) and insert the supplied battery -
all three LEDs will flash once and a long beep will be sounded. After that the green LED will start flashing. Note: the detector's
warm-up time is three minutes.
4.
Attach the detector to the mounted bracket and push it downward, until clicked into place.
5.
Connect the supplied transformer's USB cable to the detector with the and the to a 220V AC outlet.
6.
Enroll the detector; see the alarm system's installation guide for details.
The LEDs
When connecting the DGS to power, all three LEDs flash once and a long beep is sounded. After that the green LED continue to flash for
three minutes (warm-up time), before the detector becomes operable and starts the process of continually sampling the air around it.

Operation Modes
Warm-up: the first three minutes after the unit is powered up, and before the detector becomes operable.
Standby: the normal operation mode, during which the surrounding air is sampled every 10 seconds, and the detector is self-tested
every 160 seconds. The green LED will illuminate if no trouble exists.
