3. Installation and commissioning
The DG-1 digital gas detectors are designed for indoor installation.
Considering specific character of the gases to be detected, the DG-1 TCM and
DG-1 LPG detectors should be mounted in low position, just above the floor,
the DG-1 ME detector in high position, just under the ceiling, and DG-1 CO
detector at a height of about 1.5 meter.
1. Open the housing as shown in Fig. 2.
Fig. 2. Opening the detector housing.
2. Remove the electronics board.
3. Make suitable openings for screws and cable in the rear housing panel.
4. Pass the cable through the opening prepared.
5. Secure the rear housing panel to the wall.
6. Fasten the electronics board.
7. Connect the leads to corresponding terminals.
8. Using the jumper, decide whether the buzzer is to be enabled, or not.
9. Close the detector housing, making sure that the matchmarks on the cover and on the
rear housing panel are aligned (see Fig. 3).
10. Switch on power supply of the security system. Putting the detector into operation is
signaled by three short sounds, accompanied by blinking of the LED.
Notes:
•
It is not recommended to install the detector in spaces where industrial type equipment is
working.
•
During the detector operation the gas sensor heats up.
•
The DG-1 detectors are tested during production process with special gas mixtures. It is
not allowed to test the detector by any improvised methods (e.g. by using gas lighter gas).
Wherever it is necessary to confirm functionality of the detector, use the testing kits offered
by SATEL.
•
The DG-1 TCM detector does not work selectively. Alarm may be triggered not only by
chloroform vapors, but also by vapors of paints, lacquers, or alcohol, as well as by other
organic compounds (e.g. refrigerants, like freon (chlorofluorocarbon), tetrafluoroethane, or
chlorodifluoromethane, but also by cat urine).
•
In the first five minutes after power-up, the DG-1 TCM detector is stabilizing and alarm
may be triggered during that time.
