11. 110V Power Input: Connection point for the power cord.

4. Installation and Setup

4.1 Choosing an Installation Location

Proper placement is crucial for effective detection. Consider the following:

• For Natural Gas (Methane): Natural gas is lighter than air. Install the detector 30 cm (12 inches) below the ceiling and at least 1.5 meters (5 feet) away from gas appliances.
• For LPG (Propane, Butane): LPG is heavier than air. Install the detector 30 cm (12 inches) above the floor and at least 1.5 meters (5 feet) away from gas appliances.
• For Carbon Monoxide (CO): CO mixes with air. Install the detector at a height between 1.5 meters (5 feet) and 1.8 meters (6 feet) from the floor, or at sleeping level in bedrooms.
• General Placement: Avoid installing near windows, doors, ventilation fans, or areas with high humidity or extreme temperatures. Do not place behind curtains or furniture that could obstruct the sensor.

4.2 Mounting the Detector

1. Select a suitable wall location based on the gas type you primarily wish to detect and general CO detection guidelines.
2. Use the mounting holes on the back of the detector as a template to mark screw positions on the wall.
3. Drill two holes and insert wall anchors if necessary.
4. Secure the detector to the wall using screws.

4.3 Power Connection and Warm-up

1. Plug the detector's power cord into a standard 110V AC electrical outlet. The cord length is approximately 100 cm (39 inches).
2. Upon power-on, the green POWER light will illuminate, and the yellow W-UP light will flash. The device will enter a 3-minute warm-up period.
3. During the warm-up period, the detector is calibrating its sensors and is not fully operational. Avoid testing or exposing it to gas during this time.
4. Once the warm-up period is complete, the yellow W-UP light will turn off, and the green POWER light will remain steadily lit, indicating the detector is ready for operation.

5. Operation

5.1 Normal Operation

When the detector is powered on and has completed its warm-up cycle, the green POWER light will be continuously lit. This indicates that the device is actively monitoring for combustible gases and carbon monoxide.

5.2 Testing the Detector

It is recommended to test the detector weekly to ensure proper functionality.

1. Press and hold the TEST button (labeled '6' in the components diagram).
2. The detector should emit a loud audible alarm, and the red ALARM light should flash.
3. Release the TEST button. The alarm should stop, and the red ALARM light should turn off.
4. If the detector does not respond as described, refer to the Troubleshooting section.

6. Alarm Conditions and Actions

6.1 Gas Leak Alarm (Combustible Gas)

When a combustible gas leak is detected (e.g., natural gas, LPG), the detector will:

• Emit a loud, continuous audible alarm.
• The red ALARM light will flash rapidly.

Action in case of Gas Leak Alarm:

1. DO NOT operate electrical switches, light matches, or use any ignition sources.
2. Immediately open all windows and doors to ventilate the area.
3. Turn off the main gas supply valve if safe to do so.
4. Evacuate all occupants from the premises.
5. From a safe location, call your gas supplier or emergency services.
6. Do not re-enter the premises until the gas leak has been confirmed as resolved by a professional.

6.2 Carbon Monoxide (CO) Alarm

When carbon monoxide is detected, the detector will:

• Emit a loud, intermittent audible alarm (e.g., 4 short beeps followed by a pause).
• The red ALARM light will illuminate steadily or flash according to the CO concentration.

Action in case of CO Alarm:

1. Immediately move to fresh air outdoors or open all doors and windows to ventilate the area.
2. Perform a head count to check that all persons are accounted for.
3. Call emergency services or a qualified technician to investigate the source of the CO.
4. Do not re-enter the premises until the CO source has been identified and corrected, and the area has been thoroughly ventilated.

7. Maintenance

7.1 Regular Cleaning

Clean the exterior of the detector regularly (e.g., monthly) with a soft, damp cloth. Do not use cleaning agents, solvents, or abrasive materials, as these can damage the sensor or casing. Ensure no dust or debris accumulates around the gas hole/sensor area.

7.2 Sensor Life

The MOESAPU BH-H3 detector is equipped with sensors designed for a service life of approximately 10 years. After this period, the detector should be replaced to ensure continued accuracy and reliability.
