Product Usage Instructions

Safety Precautions
Before installing and using the GAS ALARM GX-A1+CO, please read the instruction manual carefully and follow the safety instructions to ensure your personal safety and optimal product function.

Intended Use

The GAS ALARM GX-A1+CO and the external sensor are designed to detect carbon monoxide gas in dry indoor rooms. This product should only be used where similar products are installed so that the warning device functions properly.

Assembly Instructions

Wall Mounting GX-A1+
Before wall mounting, loosen the four housing screws and remove the front panel. If necessary, pull off the ribbon cable from the connector. Mount the lower shell of the housing on a wall using the included mounting material. The connection cables that lead to the gas detector must be permanently installed as surface-mounted cables.

Sensor Installation

The sensor to be connected only detects carbon monoxide CO. The mounting height is crucial for optimal performance, and it is recommended to consult with a master chimney sweeper for proper installation. CO that escapes from gas boilers or similar is initially heated and rises to the top, while CO that is at the same temperature as the room air is slightly heavier than air and sinks to the floor. Pay attention to the mounting height and include your master chimney sweeper in your planning.

When installing the GAS ALARM GX-A1+CO, please note the five safety rules:

1. Turn off all potential sources of ignition before installation.
2. Do not smoke during installation.
3. Do not touch any electrical contacts without protective equipment.
4. Use only original parts and accessories.
5. Install according to the instructions provided.

SCOPE OF DELIVERY

• 1 control / display unit GX-A1 + CO
• 1 ext. CO sensor GX-5042 with sensor cable
• 1 instruction manual
• Mounting material (4 large screws, 2 small screws and dowels)

SAFETY PRECAUTIONS

General

• Before installing or using the device, read the instructions for use carefully.
• The assembly must be carried out by a qualified specialist.
• Packaging material is not a children‘s toy. Keep this out of the reach of children.

Environmental conditions

• The standards used to assess the product define limit values for use in residential, commercial and commercial areas as well as in small businesses, which means that the product is intended to be used in this operating environment:
• Residential buildings / areas such as houses, apartments, rooms, etc. Sales areas such as shops, wholesale markets, etc.
• Small business premises such as workshops, service centers, etc.
• All locations are characterized by the fact that they are connected to the public low-voltage network.

INTENDED USE

The GAS ALARM GX-A1-CO is a combination of ext. CO sensor and control unit for carbon monoxide and warns of CO concentrations that were specified in DIN EN 50291 (CO in living spaces). This monitoring system is therefore set to be very sensitive in accordance with its purpose. This CO gas warning device may only be used together with the enclosed CO sensor. An LCD display constantly informs you about the operating status. The alarm signal occurs acoustically and optically, both on the control unit and on the sensor itself. At the same time, a potential-free relay is switched to, for example, lock the gas supply line with a solenoid shut-off valve so that no more gas is used in the event of a leak in the gas line or in the gas boiler can emerge. Another relay switches if the control unit itself detects technical faults. The device must not be used in potentially explosive areas. Control unit and sensor are matched to one another. Only operate the two devices together and exclusively in dry interior rooms with similar uses, e.g. in living rooms, shops, shops, offices, in dust-free workshops, seminar rooms and much more. The device is not approved for any use other than that described above.

ASSEMBLY INSTRUCTIONS

• The assembly must be carried out by a qualified specialist. Please note the five safety rules!
• The GAS ALARM GX-A1 + and the sensor may only be used in dry Indoor rooms with similar use are installed, so that the warning device functions properly.

Wall mounting GX-A1 +
The four housing screws must be loosened for wall mounting. Then the front panel is re-moved and, if necessary, the ribbon cable is pulled off the connector. The lower shell of the housing can now be mounted on a wall
(Mounting material is included).
Important! The connection cables that lead to the gas detector must be permanently installed as surface-mounted cables.

Sensor installation
The sensor to be connected only detects carbon monoxide CO. While CO, which escapes from gas boilers or similar, is initially heated and rises to the top, CO, which is at the same temperature as the room air, is slightly heavier than air and sinks to the floor. In the DIN Norm speaks of the average nose height of the people who are regularly in the room. If in doubt, ask your master chimney sweeper.
Be sure to pay attention to the mounting height!Include your master chimney sweeper in your planning and we can advise you on the optimal installation height.

Sensor connection assignment
Note the color coding of the sensor cable, see 4.5 Connection example, S = white / M = brown / +24 = green / +5 is not used

Relay pin assignment
When connecting accessory devices to the potential-free relay, make sure that the switching current of 5 amperes must not be exceeded.

• Relay status in monitoring mode: The relay is “picked up” (NO contact closed / NC contact open)
• Relay status in alarm mode: The relay “drops out” (NO contact open / NC contact closed)

Connection example

COMMISSIONING / FUNCTIONAL TEST

An electrical function test is carried out when the mains voltage is applied, then a short initialization phase is started until the sensor is checked and the sensor self-test has been successfully completed. The display message CO: Ready confirms the successful test. Please note: The function test is restarted even after a brief power failure.
For your safety, we recommend using the system to check their function regularly!

Alarm
As soon as an alarm level is reached and the corresponding (see table 5.5) delay time has elapsed, both the control unit and the sensor alarm acoustically and optically. The control unit also switches relay Re1 in the event of an alarm. The acoustic alarm can be muted by pres-sing the TEST button (sensor) or TEST / RESET button (control unit). If the CO falls below 50 ppm, the detector resets itself.

Behavior in the event of an alarm
Ventilate the room and ensure that no further gas can escape by switching off the CO source. Inform other people to leave the room.

Maintenance / test
Briefly press the test button on the sensor to check whether its alarm device sounds and all LEDs work. Press the test button longer to observe how the ppm reading in the display of the GX-A1 + rises and the GX-A1 + also issues an alarm.
Further tests, for example with test gas, are not required for a regular test.
The sensor is generally maintenance-free. Only occasionally remove coarse dirt or dust from the device. Keep the device and the sensor away from moisture.

Display
The display constantly shows the operating status of the device. From 50 ppm CO, the exact ppm value is also shown on the main screen (display). You can get more information about the device by scrolling through the displays with the SERVICE button. These are saved permanently and cannot be reset.

Alarm thresholds and delay times
DIN EN 50291 defines alarm delay times depending on the gas concentration.

When developing the sensor, the shorter times were taken into account.

Malfunctions
The control unit can recognize its own technical faults and output them with an error code or a yellow flashing LED. In addition, relay 2 switches, e.g. to inform the building management system about it. Unplug the device for at least 1 minute and then restart it. If the error cannot be rectified, look for the error code on one of the pages that you call up with the SERVICE button and contact us. It can take up to a minute for the relay to switch, as the device first tries to correct the error by internally restarting it.
