DG-1

DIGITAL GAS DETECTORS

dg1_en 06/18

The DG-1 detectors are designed to detect dangerous concentrations of:

DG-1 CO – carbon monoxide,

DG-1 LPG – propane-butane gas,

DG-1 ME – natural gas (methane),

DG-1 TCM – soporific gases (e.g. chloroform vapors).

The detectors are intended to be used as part of a security system. This manual applies to

the detectors with electronics version 2.0.

1. Features

 Digital algorithm of gas detection.

 Digital temperature compensation.

 Prealarm feature (DG-1 LPG and DG-1 ME only).

 LED for optical signaling.

 Sounder for acoustic signaling.

 Supervision of gas sensor (not applicable to DG-1 CO) and supply voltage.

 Tamper protection against cover removal.

Detecting dangerous gas concentrations

The detector will alarm when it senses a dangerous gas concentration. For information about

the gas concentrations that trigger an alarm, please refer to Table 1. The alarm is signaled by

sound and by LED indicator (repeating sequence: sound/LED ON for 1 second followed by

1-second pause, etc.). When the alarm is being signaled, the alarm output is active (relay

contacts are open). The detector will stop alarming when the gas concentration drops below

the dangerous level. The gas sensor reaction to a decrease in the dangerous gas

concentration is delayed, hence the alarm signaling can stop even a few minutes after

the gas concentration has dropped below the alarm level.

Table 1.

The DG-1 LPG and DG-1 ME detectors signal prealarm. For information about the gas

concentrations that trigger a prealarm, please refer to Table 1. Prealarm is signaled by sound

and by LED indicator (repeating sequence: sound/LED ON for 0.25 second followed by

1-second pause, etc.). Prealarm does not affect the state of alarm output. The detector keeps

signaling prealarm as long as the methane/propane-butane concentration remains above the

10% and below the 20% lower explosive limit.

Supervision of gas sensor and supply voltage

The detector will report trouble in the event of sensor defect (not applicable to DG-1 CO) or

when the supply voltage drops below 9 V (±5%) for longer than 2 seconds. Troubles are

signaled by sound and by LED indicator (repeating sequence: sound/LED ON for 0.25

second followed by a 0.25 second pause, etc.). When the alarm is being signaled, the alarm

output is active (relay contacts are open).

3. Installation and commissioning

Disconnect power before making any electrical connections.

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 detector enclosure (Fig. 2).

2. Remove the electronics board.

3. Make suitable openings for screws and cable in the enclosure base.

4. Pass the cable through the opening prepared.

5. Secure the enclosure base to the wall.

6. Fasten the electronics board.

7. Connect the leads to corresponding terminals.

8. Using the jumper, decide whether the sound signaling is to be enabled, or not.

9. Close the detector enclosure, making sure that the matchmarks on the cover and on the

enclosure base are aligned (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.
